Introduction

The Unit is a flexible platform consisting of a base unit or chassis in to which various option cards can be plugged. The base unit provides an Ethernet control interface, and Ethernet data interfaces, it also provides basic transport stream processing functionality. Other functionality such as video encoding, audio encoding, or other input or output interfaces are provided by option cards.

License Keys

License Keys control the availability of some of the features accessible from the unit and are issued to a specific chassis, not an option card, and are held within the chassis.

Base Chassis

This section introduces the chassis and describes the functions associated with the host controller.

Option Cards

The following are the available option cards:

EN7100 SD MPEG-2 VCM

This provides high quality MPEG-2 Video encoding, and audio encoding.

EN8100 SD MPEG-2 VCM

functionality being enabled is provided by an option card.

Features

License Keys consist of a feature, and the number of instances of this feature that are allowed within the chassis. License Keys are allocated on a ‘first configured first served’ basis within the chassis. If an attempt is made to enable a feature, but the required license key is not available then the feature is not enabled, and a log message is generated. When a function that has a license associated with it is disabled, the license key is released within 1 second, and therefore available to be re-allocated .

Verifying which licenses are present in the Unit

Access to the encoder web pages is necessary to verify the licenses that are enabled on the unit. Navigate to Configure > System > Licenses feature enabled by the license.

NOTE : Short term licenses are not supported.

Ordering Additional Licenses.

When ordering additional licenses for existing units the following information is needed:

1. Unique Chip ID of the unit is required to generate the key. This is retrieved by navigating to the following web page :

Configure > System > Base Unit > Advanced > ChipID

2. The TOTAL FINAL number of licenses required (including licenses already enabled on the unit) needs to be provided.

The above information is used to generate a new license key file, which then needs to be loaded onto the appropriate unit.

Entering License Keys

The keys are saved in an XML (newlicensedetail.xml) ready to be entered onto the unit via the web page Browse to: Configure > Licenses In the license box enter the license filename and select upload.

NOTE : The front panel CANNOT be used to enter license keys!

The option cards provide the video, audio and data processing functionality and can be ‘Hot Swapped’, i.e. inserted or removed whilst the chassis is powered.

Why Have Two Mains Connectors

Many broadcasting sites have two power supply chains, either from the master switchboard or, for major sites, from different points on the supply grid. As the most common cause of system failure is loss of power, feeding the chassis from the separate chains ensures reliability of supply and, therefore, continuity of service.

Audio Encoding

Overview

Up to eight channel pairs can be de-embedded from the HD-SDI or SDI video input, or up to four channel pairs can come via the 15 way D-Type Audio Input connector on the cards rear panel as either balanced or unbalanced AES/EBU digital audio.

If a /SWO/DOLBY/AC3 license key is available, two audio channel pairs may be encoded in accordance with the Dolby Digital specification.

Up to eight audio channel pairs of uncompressed audio can be encoded in accordance with MPEG-1 Layer II, subject to license key /SWO/M1L2 for more than two channels.

Audio that has already been Dolby Digital encoded can be input, and suitably encapsulated for inclusion in an output transport stream (pass through mode).

A total number of eight audio channel pairs can be processed of which up to two channel pairs can be encoded in accordance with the Dolby Digital specification

Audio Input

The Pre-processing function on the VCM accepts digital audio input from either de-embedding from the HD/SD-SDI input, as a balanced pair (110 Ω) or unbalanced input (75 Ω) from the D type back panel connector. See Technical Specification for more details.

HD-SDI Input

Audio can be embedded on a serial digital interface (HD-SDI) feed within four groups. Each group contains two pairs. Hence each HD-SDI can carry up to a maximum of 2 x 4 = 8 pairs, or 16 mono channels.

Each group has an associated Data Identifier (DID). The DIDs are set to the SMPTE 299M defaults for audio group 1 to group 4:



Group 1 = 0x2E7



Group 2 = 0x1E6



Group 3 = 0x1E5



Group 4 = 0x2E4

The DIDs are located in ancillary packets in the data stream. They are fixed at the SMPTE 299M defaults.

SD-SDI Input

Audio can be embedded on a serial digital interface (SDI) feed within four groups. Each group contains two pairs. Hence each SDI can carry up to a maximum of 2 x 4 = 8 pairs, or 16 mono channels.

Each group has an associated Data Identifier (DID). The DIDs are set to the SMPTE 272M defaults for audio group 1 to group 4:



Group 1 = 0x2FF



Group 2 = 0x1FD



Group 3 = 0x1FB



Group 4 = 0x2F9

The DIDs are located in ancillary packets in the data stream. They are fixed at the SMPTE 272M defaults. DID 1F4 is reserved for EDH error packets. Refer to the SMPTE 272M specification for more details.

Audio Input

The digital input of the VCM accepts four stereo pairs of digital audio. See Technical Specification for more details.

CAUTION...

When the digital audio source is used with the AUDIO IN connector, consideration must be given to the choice of clock source used by the Encoder. To ensure correct operation, both the Encoder and the audio source may need to be genlocked to the studio source by selecting the video clock as external. Then the encoding clock is derived from an External Sync module.

Audio Encoding Modes

Up to eight audio channel pairs of uncompressed audio can be encoded in accordance with MPEG-1 Layer II, subject to license key SWO/M1L2 for more than two channel pairs.

If a SWO/AC3 license key is available, two audio channel pairs may be encoded in accordance with the Dolby Digital specification.

Pre-encoded Dolby Digital, Dolby Digital Plus and Dolby E inputs can be suitably encapsulated for inclusion in an output transport stream.

The VCM can generate a 1 kHz test tone, which may be used in place of any audio input.

Any audio input can be associated with the video being processed, and the audio encoding delay will be matched to the video encoding delay so that audio/video synchronisation (lipsync) is maintained.

All Audio modes are configurable on a per channel basis, which includes the source of the audio, its encoding configuration and output PID. The following is a summary of the Audio Compression functionality available.

Dolby Digital pass through (Dolby Digital AC-3)

Dolby Digital Plus pass through Glitch suppression is supported in this mode 8 DolbyE pass through Compliant with SMPTE 302M 8 LPCM pass through Compliant with SMPTE 302M 8

Glitch suppression is supported in this mode 8

Glitch Suppression Mode

When in Dolby Digital pass through mode, the coding module monitors the encoded bitstream and if the framing structure is incorrect, a valid silence frame or the last good frame is inserted in its place. If this state occurs for more than a second, the Encoder signals that the Dolby Digital bitstream is corrupted.

Test Tone

The VCMs can generate a test tone on any audio channel at 1 kHz

Advanced Settings

Dolby Digital (AC-3) components by default use the descriptor defined by the DVB in the PMT. However the AC-3 PMT Descriptor Syntax control available in the Audio Module/Advanced menu enables this descriptor to be forced to the ATSC AC-3 descriptor.

Vertical Blanking Interval (VBI) Data

General

All VBI information carriage are configurable (either enabled or disabled). The video line from which the VBI is extracted is configurable. The default is set according to the recognised standard for the VBI type.

VBI Lines

Up to at least 8 VBI lines per field can be extracted. Unless otherwise stated, all VBI data are formed into one VBI transport stream packet that conforms to ETSI EN 301 775 or SCTE 127.

In this release the ASI outputs are mirrored - the same transport stream is transmitted from both outputs.

Two 75 Ω female BNC input connectors are also available but are not supported in this release.

The ASI option module uses the 27MHz clock and System Reference Clock (SRC) from the base chassis backplane as its frequency reference.

The output bit rate of the ASI Card is configurable up to 216Mbps. The module automatically determines if the packets are to be sent either in Burst or Byte Mode. If the TS rate is less than 70Mbps, packets are sent in byte mode. Above 70Mbps burst mode is used.

External Sync Input

The External Sync Input card provides a 75 Ω female BNC connector to allow an external synchronization signal to be input to the unit. This signal may then be used as the frequency reference for the units 27 MHz System Clock Reference.

The input signal may either be: 1 V peak to peak PAL or NTSC black and burst video signal. 1 V peak to peak 10 MHz square wave or sine wave reference.

Static Parameter Issues

1. The default line standard within the Video Processor with a new device is 625 line 25Hz. If the unit is not configured within the

devices. It is therefore recommended that the static parameters are re-read for devices when they are running a live profile such that the default settings are appropriate for that system.

2. In the event of a software upgrade to the encoder, the static parameters should be re-read for upgraded devices, to ensure that

there is no mis-match between the XML in nCC and in the unit.

Current recommended procedure for upgrading encoders:

Schedule blank profile and blank map, set nCC off, upgrade encoders, set nCC on, load map, get static parameters, save map, schedule profile.

NOTE : In both the above cases, if static parameters are not re-read, any changes that have been made to the defaults on

the encoder will be over-written if nCC is taken off line and then re-started, as the nCC static parameters will be loaded onto the encoder. In the case of the upgraded units, this could result in loss of operation.1.

Video Processor UDP Port Numbers



nCC defines the Video Processor UDP Port Number



The range of these ports are defined within nCC during initial setup.



Each slot within a Video Processor Chassis is automatically given its own unique Port (Encoder Port), determined by the Base Reflex Port.

Example: Slot Port 1 6010 2 6020 3 6030 4 6040 5 6050 6 6060



These port numbers are fixed on a system basis and are re-used across all Video Processor chassis.



These port numbers are used for both the control network and the data network (PCR exchange).

Backwards Compatibility



If other Reflex v4 protocol enabled encoders are used within an Video Processor encoder system, then they should assume definition of the slot 1 encoder card



If a Video Processor is used as a replacement in a legacy system, then the Port number used should be allocated as per the allocation with the legacy encoders.



If a Video Processor is used as a replacement in a legacy system, it may only be a single encoder card device. That card must be fitted to slot 1.



Mixed systems with legacy encoders should start with a base encoder UDP reflex port of 6003 for DIPNIC support. This will be defined by the Engineer installing the system.



Reflex only works with other Video Processor MPEG-2 SD Encoders in the same statistical multiplexer pool. Not in a mixed encode type statistical multiplexer pool.

Each Muxlet will use the Source Port (Mux Port) number 6003



The first video module within an encoder card should use the multi_video_idx of 1



Subsequent video modules should increment in value from 1 (i.e. 2, 3, etc.)



This range should be the same for all encoder module types, regardless of video encoder type (e.g. MPEG2, H264).



Legacy encoder configuration should not change

TS Bit rate overheads for the Video Processor in nCC



When the TS rate is changed on the output of the Video Processor, there is a small period of disruption. As the nCC dynamically allocated this rate depending on component rates, a compromise solution is that the nCC configures each multicast by default from a Video Processor at 20 MBit/s TS rate. This has a safety feature in case the TS rate required is greater than this value then the dynamic update takes precedence.

NOTE : In large systems it may be necessary to reduce the TS rate due to input TS rate limits in the Multiplexers.

Multi-VCM Operation & Redundancy



The Video Processor spare must have sufficient duplicate VCMs to switch the entire chassis

The Video Processor in R2AFD1 supports inter-chassis redundancy only – Redundant VCM must be in spare chassis, not same chassis

Redundancy Steps:

MPEG-2 Compliancy

The encapsulated transport stream packets (video, audio, VBI/ANC data and PCR - 188 bytes), are fully compliant MPEGstreams (all relevant fields completed, continuity counters, PTS/DTS, adaptation fields etc.).

Transport Streams

The system can form up to six output transport streams.

Transport Streams are encapsulated in either a UDP or a UDP and RTP packet and can have added Pro-MPEG FEC packets before being transmitted out of the assigned Data Ethernet port(s).

Pro-MPEG FEC

Pro-MPEG FEC (Forward Error Correction) as per SMPTE 2022 1/2 can be added to the MPEG-2 Transport Stream to improve the reliability over IP networks if the relevant license (/SWO/PROFEC) has been purchased. One license instance is required by Transport Stream.

Output Data Rate

The system is designed to support a maximum output data rate of 120 Mbps.

The bit rate of each output transport stream can be individually controlled with a resolution of 1 kps.

Transport Stream Parameters

The output rate of all transport streams is derived from the Base Unit's 27 MHz clock. This can be locked to any 27 MHz or 10 MHz clock provided by an option card, or can free run. This means that it can be locked to an option card's video input, or locked to the external sync input on the External Sync Module.

Background

Forward Error Correction or FEC, enables packets lost during transmission over IP networks to be recovered by adding extra information to the transmitted data. The particular type of FEC used on the unit is that specified by SMPTE 2022 1/2.

The key features of Pro-MPEG FEC are:

• Open standard FEC scheme.

• Increased robustness of transmission.

• Increases network reach through FEC on high loss links.

• Highly configurable depending on bandwidth vs. robustness.

• FEC transmitted separately to media stream.

• Independent of video compression standard (MPEG-2, MPEG-4).

Pro-MPEG FEC can help to solve the problems caused by missing packets. It is an open standard for protection of contribution broadcast real-time transmissions over IP networks by facilitating real-time lost packet recovery at the receive units. It permits flexible configurations for optimisation requirements. The scheme uses an RTP layer which adds timing information for sequence correction. FEC packets are transmitted in separate IP packets. It uses a matrix of media packets to calculate the FEC packets. The matrix size defined by columns (L) and rows (D). FEC packets are calculated along columns and rows using the XOR function. FEC can be 1D (Column Only) or 2D (Column and Row). Media and FEC packets are transmitted on separate IP streams with the Column

from Media stream and has UDP port number which is the media port number +4. This arrangement means that non-enabled FEC receivers can simply ignore FEC streams and decode the media packets. The FEC data stream is off-set from the media stream to protect against burst error loss and jitter. At the receiver, lost packets recovered using the FEC data packets. The Column FEC protects against burst errors and the Row FEC protects against random errors. Pro-MPEG FEC recovers lost packets using column and (optionally) row FEC packets using the XOR function on the remaining packets. Depending on the distribution and severity of the pack loss not all errors are recoverable.

The overhead which results from Pro-MPEG FEC transmitting extra packets depends on whether column or column and row FEC is selected and how many columns and rows there are. (Note that L = number of columns, D = number of rows.)

Column FEC: 1D FEC Overhead = (L+(D*L))/(D*L) = 1/D + 1

Worst case, 4 rows = 25%

Best case, 20 rows = 5%

Column and Row FEC: 2D FEC Overhead = (D+L+(D*L))/(D*L)

Worst case, 4 x 4 = 50%

Best case, 10 x 10 = 20%

FEC offers two methods of block alignment (also referred to as FEC linearisation) for use when generating FEC packets: Non Block Aligned and Block Aligned. Both are guaranteed of being able to correct L errors, sometimes more. The Block Aligned method can however correct 2L+2 errors; this never happens with Non-Block Aligned.

Non-Block Aligned can in theory have a lower latency at the decoder if it can be guaranteed that the mode of operation will never change.

Block Aligned linearisation is dealt with in Annex B of the Pro-MPEG Code of Practice. In Block Aligned column FEC packets are sent

every D’th frame and the L Column FEC packets are played out every D slots. They are therefore evenly spread over the D*L matrix period.

Non Block Aligned linearisation is dealt with in Annex A of the Pro-MPEG Code of Practice. In Non Block Aligned the matrix is

skewed’ for the column calculation. The L column FEC packets are played out at the end of every column plus a constant. For

square’ matrices (diamonds) where L=D then these column packets will emerge at regular intervals. For ‘rectangular’ diamonds they will not. In the case of a 4 column by 20 row matrix the 4 FEC packets will emerge within 16 slots, followed by a gap of 64 slots before the next 4. It therefore produces a less linear spread of packets.

Receivers which do not have FEC capability can simply ignore the FEC packets and just make use of the media packets.

Services

Overview

The system is capable of forming up to six services divided between the output transport streams. Each service can contain a maximum of 16 elementary streams. The elementary streams that make up a service can be selected from the elementary streams available from the option cards. The only restriction is that the elementary streams in a service must all reference the same 27 MHz clock. An elementary stream can be included in up to eight services, but the PID of the elementary stream must be the same in all services. Only one video elementary stream can be assigned to a service, and the audio delay of audio services should be matched

to that video. Only one PCR can be associated with a service.

Service Information Tables

The SI tables that the system generates for each individual output transport stream can be selected. The following table shows the available levels.

SI Level Description

Off Elementary streams only

PAT/PMT Only PAT/PMT are generated

PAT/PMT/CAT/SDT

Some users may not require ETR 290 compliance, so it is possible to set the PMT repetition rate to either 100 ms (default) or 500 ms.

The listed tables are generated. The CAT will be empty as Conditional Access is not supported in this release.

Formation of SI

SI packet formation and play out is the responsibility of the host card. However it is the Video Encoding module's responsibility to provide SI data fields related to the stream that it is generating.

Repetition Rate

The repetition rate of SI packets must take in to account the output transport stream rate, otherwise the jitter introduced by the multiplexing of packets to form the transport stream can lead to the SI repetition rate being too long.

Coded Elementary Stream

Overview

The compressed output streams from the module are in the form of MPEG-2 transport packets that have been encapsulated into a transport stream packet.

The output rate of the transport packets are derived from the 27 MHz reference clock and are accurate to within 1 kbps of the configured bit rate (transport rate). The output video bit rate of the VCM is configurable within ranges dictated by operating mode. The configured video rate means transport rate. The rate control operates on the transport rate. The module supports bit-stuffing to maintain configured bit rate if the operating mode requires it. The output of a module never exceeds the configured bit rate (or bit rate ceiling).

PCR Placeholders

The VCMs enable a PCR placeholder to be put in the adaptation field of every video PID stream. See Appendices > Clock and Timing > Program Clock Reference (PCR).

Transport Packets

The VCMs support adaptation field stuffing of transport packets for the alignment of PES packets to transport packet boundaries. Valid continuity counter values are inserted into the transport packet headers.

Audio Output

Encoding

The audio encoding supports encoding at 48 kHz only.

The audio output is formed of fully compliant MPEG-2 transport packets encapsulated into a transport stream packet. The module runs in aligned mode where there are an integer number of audio frames fitted into a PES packet, therefore a PES packet will be the start of an audio packet. The audio output rate is derived from the 27MHz reference clock.

Lip Sync

The Video Encoding module ensures that lip sync is maintained between the limits of audio leading video by 10 ms to video leading audio by 30 ms.

PID Assignment

The module enables a PID to be assigned to each audio channel separately, which includes the ability to assign separate PID’s to every mono channel. The PID value is configurable.

PCR Placeholders

The module enables a PCR placeholder to be put in the adaptation field of every audio PID stream. See Appendices > Clock and Timing > Program Clock Reference (PCR)

Audio Reference Output Signal

A 48 kHz digital output reference signal is provided to enable an external audio encoder to be locked.

The Video Encoding module supports adaptation field stuffing of transport packets for the alignment of PES packets to transport packet boundaries. PES streams carry the stream_id = 0xE0.

Transport Packet Headers

PIDs used in the transport packet headers are configurable and have valid continuity counter values inserted.

Packetised Video Elementary Streams

The compressed video data is packetised within MPEG-2 PES packets which are configurable to be per picture or per GOP.

VBI Data on a Separate PID

The VBI data is packetised within MPEG-2 PES packets as specified in ETSI ETS 300-472 (teletext), ETSI EN 301 775 or SCTE 127 for all other VBI data.

The Video Encoding modules support adaptation field stuffing of transport packets for the alignment of PES packets to transport packet boundaries.

PID Assignment

Assigning PIDs

If a PID has not been assigned a value (or is a value of 0) a unique PID will be allocated to that component.

Duplicate PIDs

If a PID is given a value that is already in use, a Duplicate PID alarm is raised in the logs that identifies the transport stream and PID.

There is no facility to automatically re-assign duplicate PIDs to a unique value.

Ethernet: Control

Overview

The Base Chassis has two Ethernet control ports that support IEEE 802.3 100BASE-TX and 1000BASE-T protocols. The control ports are accessible via RJ-45 connectors mounted on the rear panel of the unit.

Ethernet Control Port Numbering

The Ethernet control ports are used to connect the unit to a web browser or the control system (nCompass Control [V6.5 onwards]).

Ethernet Control Port Parameters

NOTE : Control via the Data input ethernet ports is not supported

A single IP port is defined for all ethernet control of the chassis. The physical ports used for ethernet control are by default the control ethernet ports. The control ports can raise an alarm during abnormal operational conditions, (see Looking After the Unit > Troubleshooting > Handling Alarms > Alarms - Control Port).

The parameters defining the control ethernet port are as shown in the following table

Data Output

The unit can generate one or more output transport streams from the components produced by the option cards fitted. The output transport stream packets are encapsulated in IP packets prior to being transmitted via the Ethernet Data ports. The base chassis does not provide any other interface by which to output a transport stream.

Data Network Redundancy

Both outputs of a pair are active at the same time, therefore the use of primary and secondary ports is meaningless in

Redundancy

NOTE :

The four Ethernet data ports operate as two redundant pairs. Data 1 and 2 (Ge1 with Ge2), and Data 3 and 4 (Ge3 with Ge4).

When an output transport stream is defined, it is assigned by the user to one or other data output pairs.

Both ports are independent of each other i.e. the IP address, MAC address, subnet mask and default gateway can have different settings. Both ports are active at the same time and transmit the same data. If both ports are configured to be on the same subnet, only one port will respond to ICMP messages.

IP Encapsulation of MPEG Transport Streams

This topic describes how an MPEG-2 transport stream is carried over an IP link.

1 to 7 MPEG Transport Stream Packets RTP Header (optional) UDP (User Datagram Protocol) IP (Internet Protocol) Ethernet (IEEE 802)

Between one and seven MPEG transport stream packets are carried in a UDP packet. The UDP packet may optionally also contain an Real Time Protocol (RTP) header, which adds additional information such as a sequence number and a timestamp, which can help in the detection of packet loss across a network. The UDP header is 8 bytes long, and the RTP header is 12 bytes long. The network layer protocol is IPV4, which adds a 20 byte header to every packet. The physical link layer is then Ethernet at either 100 Mbps or 1000 Mbps.

would not normally be encoded. Apply a 120 Hz low pass filter prior to an encode. Should only be switched off if it is

known that there are no frequencies above 120 Hz. Attenuate surround channels by 3 dB before encoding. Theatrical and consumer mixing

rooms use different levels for the surround channels, and this can be used to compensate. Apply a phase shift of 90 degrees to the surround channels. This simplifies the decode

process for producing a 'Lt/Rt' downmix.

Dolby E Transcode

A Dolby E encoded audio input can be decoded and subsequently re-encoded using a different coding algorithm if a /VP/SWO/DOLBYE/DEC license is available.

The following parameters configure the audio decoder:

Parameter Description

Decoder Main Input

Decoder Switchout Input

Specifies the main decoder input source, ie, the source of compressed (Dolby E) audio frames. Set to ‘Off’ to disable the audio decoder.

This source is used when Dolby E ‘switchout’ is active. This input must always carry uncompressed audio (linear PCM).

When set to ‘On’, the main input is passed through to program outputs 1at the input (see diagram below).

PCM Bypass

Switchout

Decoder Status

When the decoder is enabled, the decoder reports whether it is locked to a valid compressed audio (Dolby E) stream. A valid stream is defined as follows:

• Compressed (Dolby E) audio frames are embedded in the AES3 data according to SMPTE 337M.

• The Dolby E frame must be correctly formatted with a valid CRC.

• For Dolby E, the video frame rate indicated in the Dolby E stream must match the current video frame rate used by the video encoder. An alarm is generated if the frame rates do not match. The decoder also reports if PCM bypass and/or switchout are active. The Dolby E program configuration, video frame rate and bit depth are reported when the decoder is locked to a valid Dolby E stream. It is possible to view the Dolby metadata associated with each Dolby E program by navigating to Audio Module N ->

-> Metadata Status -> Metadata Status (Program X) menu.

always match the current input metadata.

The following parameters configure an audio encode of the decoder output:

Parameter Description

Input Source

Dolby E Program

The parameters listed in the table below control downmixing at the input to the encoder, if it is required to match coding modes. By default downmix is controlled by the Dolby metadata from each decoder output as each Dolby E program has its own associated Dolby metadata. However it is possible to override the Dolby metadata parameters with user-specified (fixed settings) if desired.

Parameter Description

Downmix metadata override

Downmix metadata reversion mode

When set to ‘Off’, program outputs 1-4 are replaced with silence if compressed audio is not detected at the input.

Program outputs 5-8 are always replaced with silence when compressed audio is not detected at the input. When set to ‘Auto’, uncompressed audio on the ‘switchout’ input is passed through to program output 1 if

compressed audio is not detected at the input (see diagram below). When set to ‘Off’, the ‘switchout’ input is never used.

Specifies the encoder input source. For audio transcode, the input source should be set to ‘Decoder 1 (Audio Module N)’, where N is the audio

module number (1 on the EN8100, 1 or 2 on the EN8190). Set to ‘Off’ to disable the encoder.

This is used to select the program output (1 to 8) from the Dolby E decoder. For example, for a 5.1+2 Dolby E stream, then program 1 contains the 5.1 stream and program 2 contains the 2.0 stream.

It is possible to route the same Dolby E program to multiple encoders if desired. If the specified Dolby E program output is not present in the Dolby E stream, then the encoder input is

replaced by silent audio and an alarm is generated.

Set to ‘On’ to always override the downmix parameters in the metadata with fixed (user-specified) parameters.

Set to ‘Off’ to use the metadata values (if they exist). Specifies the behaviour on loss of metadata from the decoder output.

Set to ‘Use fixed settings’ to use the user-specified parameters when metadata doesn’t existed. Set to ‘If available, maintain last received metadata values, otherwise use fixed settings’.

Downmix type

Centre mix level Sets the centre channel mixing levels when downmixing to L/R channels (-3.0 dB, -4.5 dB or -6.0 dB). Surround mix level Sets the surround channel mixing levels when downmixing to L/R channels (-3.0 dB, -4.5 dB or zero gain).
