Introduction

The Unit is a flexible platform consisting of a base unit or chassis into which between one and six Media Processing Modules (MPMs) can be plugged. The base unit provides an Ethernet control interface, and Ethernet data interfaces, it also provides transport stream processing functionality. Other functionality such as video / audio transcoding, or other input or output interfaces are provided by the media processing modules.

License Keys

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

Base Chassis

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

Media Processing Module (MPM)

The following media processing module is available:

MPM1 HD/SD Transcoder

This provides high quality MPEG-2 and H.264 Video transcoding, and multi-standard audio transcoding.

Page 16

Home > SPR1100 Handbook > Introduction > License Keys

License Keys

Overview

License Keys control the availability of some features and are issued to a specific base unit not a media processing module, even if the functionality being enabled is provided by a module.

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 transcoder web pages is necessary to verify the licenses that are enabled on the unit.

Navigate to Configure > Licenses. This page displays the marketing code, number of each license and a description of the feature enabled by the license.

Ordering Additional Licenses.

N.B. License keys are unit-specific. They cannot be loaded onto a different unit.

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

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

The Chip ID value is displayed just beneath the diagram of the transcoder.

The TOTAL FINAL number of ALL types of license required (including licenses already2.

Page 17

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 file (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!

SPR11/CHASSIS/2AC 1U Base Chassis (Dual AC)

Overview

The Ericsson SPR1100 consists of a base chassis, dual AC inputs and up to four modules. The base chassis is a 1 ‘RU’ 19" rack mount chassis that provides the control interfaces, and two pairs of dual redundant Ethernet ports for data input and output.

The modules 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.

Manual Configuration via the Web Pages

The Ericsson SPR1100 has been designed to be configured and controlled by its own web interface, which is described here.

The main Transcode Configuration page can be found by the following navigation :

Configure > Services

1) Configure Input Streams

The left-hand panel of the Transcode page defines the input Transport Streams to be processed by the unit.

Page 82

Transport Streams are grouped by Physical Interface. Each Transport Stream is defined by its IP address and port number. Multiple services can reside within each transport stream, with multiple components within each service.

The tree of input streams is navigated by expanding and contracting items using the and

buttons alongside. All entries within an item can be expanded by right-clicking on that

item and selecting Expand All .

Selecting an item (by clicking on it) causes the relevant properties for that item to be displayed in the "Properties" panel. Properties that cannot be edited will be "greyed out".

Transport streams may be added to a Data Interface by right-clicking on the interface entry and selecting Add transport stream .

2) Configure Output Streams

The second panel from the left defines the output Transport Streams that will be produced

Page 83

by the unit.

Transport Streams are again grouped by Physical Interface. Each transport Stream has an IP address and port number, and can contain multiple services, with multiple components in each service.

Transport Streams may be added in several ways:

Right-clicking the Output Interface and selecting Add transport stream . Dragging streams or services from the Inputs panel and dropping them onto an appropriate place in the heirarchy of the Outputs panel.

NOTE:

Each input service may be used in up to two independent (and different) transcode operations. This is achieved by dragging the same input service to multiple output multicasts. Each transcode will require a separate license.

Output services can be duplicated up to four times, so that the same transcode operation can be included in up to four output Transport Streams. This is achieved by right-clicking on

Page 84

the output service and selecting "Duplicate Selected on output".

3) Configure the Transcode Operations

Each item in the Outputs panel can be configured at its position in the heirarchy. This allows the operator to configure all dependent items together; for example, selecting a transport stream would allow all services within that transport stream to be configured together. Individual components can also be altered if a common configuration is not desired.

Page 85

For each item selected, a number of panes will appear in the Properties panel. These include:

Transport Stream Service Video Component Video PIP Component

Audio Component Not all of these will be available for every component. Each pane of the configuration may have several sets of parameters that may be

configured. These are arranged in a tabbed interface within the pane.

Page 86

4) Warnings, Errors and History

At the bottom of the Services Configuration page is an "Information" panel. This can show Warnings, Errors, or Change History according to the tab selection on the left hand side

5) Allocation Status

With the very dense transcode configurations possible with the Ericsson SPR1100, it is all too easy to lose track of exactly how much of the unit's resource has been used.

To assist the operator in managing the total allocation usage, the Services Configuration page has an Allocation pane to show the amount of resource allocated or available with the configuration currently set up on the page.

If more detail is required, the panel has a "Details" tab which will show the allocated/available breakdown for each transcode type.

6) Apply Configuration

Page 87

All configuration changes initially only occur in the User Interface. The Ericsson SPR1100 does not change its behaviour until the operator presses the "Apply All" button.

Once the configuration is applied, the unit is updated with the new configuration.

NOTE:

Changing the configuration may cause output glitching. This is kept to a minimum; transcoder units which do not need reconfiguration will not be interrupted. Additionally, changing the output bit rate will not cause a glitch.

MPEG-2 Compliancy

The encapsulated transport stream packets (video, audio, VBI/ANC data and PCR - 188 bytes), are fully compliant MPEG-2 transport streams (all relevant fields completed, continuity counters, PTS/DTS, adaptation fields etc.).

Transport Streams

The system can form up to 128 output transport streams, with each stream mirrored on the two physical output interfaces.

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).

ProMPEG FEC

ProMPEG 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 (SPR/SWO/PROFEC) has been purchased. One license instance is required per Transport Stream.

NOTE:

The ProMPEG FEC functionality is not yet available on this product. Please contact Customer Services for more details.

Background

Page 94

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 ProMPEG 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). ProMPEG 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 FEC stream offset from media stream and has a UDP port number which is the media port number +2. The Row FEC stream is offset 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. ProMPEG 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 ProMPEG 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 ProMPEG 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 ProMPEG 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 72 services divided between the output transport streams.

Each service can contain a maximum of 18 elementary streams, consisting of a maximum of 8 data components, 8 audio components, one main video and one PIP video component.

An elementary stream can be included in up to four services. Only one main video elementary stream can be assigned to a service, and the audio delay will be matched to the video. A PIP Video stream may also be added. 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

On (PAT/PMT Only)

PAT/PMT are generated

On (PAT/PMT/SDT/CAT)

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

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.

Formation of SI

SI packet formation and play out is the responsibility of the host card. However it is the Media Processing 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 into 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.

Output Bit Rate

The output rate of the transport packets is derived from the 27 MHz reference clock and is accurate to within 1 kbps of the configured transport bit rate.

The output video bit rate of the MPM is configurable within ranges dictated by the operating mode. These ranges are listed in the MPM1 Feature Summary page. The configured video rate means the transport stream 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

The MPM will insert a PCR in each video stream header. See Appendices > Clock and Timing > Program Clock Reference (PCR).

Transport Packets

The MPM supports 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.
