1.1.5 Service Availability
The EN8030 Encoder is able to generate an MPEG-4 Standard Definition output and the
EN8090 Encoder is able to generate an MPEG-4 High Definition output or an MPEG-4
Standard Definition output.
1.2 Modes of operation
1.2.1 MPEG-4/H.264 AVC over TS
The elementary streams from the EN8000 H.264/AVC encoding module are encapsulated into
an MPEG TS (Transport Stream) system within the Encoder.
• Video: Main and High Profile of the ISO/IEC 14496-10 (H.264/AVC) technology are
supported.
• Audio: There is a wide range of audio encoding standards that can be used including
MPEG-1 Layer II and Dolby Digital.
• Output: The elementary streams from the Intelligent Compression Engine (ICE) card are
multiplexed on the motherboard of the Encoder into a compliant single-program transport
stream. Hence, the combined output of these streams is through the ASI outputs on the
motherboard.
• Option: An IP/Ethernet output card (EN8000/HWO/IPTSDUAL) can be fitted to the
EN8000 range of encoders to allow the transmission of TS over IP using RFC 22 50.
The details of this are shown in Table 1.2.

Output
TS outputs on the Encoder: the standard is ASI output but this can extend to IP using the IP/Ethernet
output option card.
1.2.2 Picture-in-Picture
If the software option EN8000/SWO/PIP is purchased for the Encoder, there is the capability
of generating a second, reduced resolution, video image. The Encoder prod uces a multiple
program transport stream (MPTS) where one service is the broadcast stream and the other
contains the reduced resolution video image. This is covered in more detail in Chapter 3, Options and Upgrades and Chapter 6, Picture in Picture.

1.3 Video Encoding
1.3.1 SD Video Inputs (EN8030 Encoder)
The standard video inputs are:
• SDI - Serial Digital Interface - ITU-R BT.656-4, part 3 (D1 serial format) – SMPTE 259
• 525-line composite NTSC-M (with and without pedestal) or PAL-M (ITU-R BT. 624-4)
• Serial digital (ITU-R BT.656-4, part 3) input (D1 serial format) and (ANSI/SMPTE 259M)
(component only)
• Internal test pattern function
Serial Digital Video Input Error Detection and Handling (EDH)
Introduction to the Basic Encoder
The serial digital video input supports error detection and handling (EDH) as defined by the
specification SMPTE RP 165-1994, ‘Error Detection Checkwords and Status Flags for Use in
Bit Serial Digital Interfaces for Television’.
Video Pre-processing
The efficiency of the encoding can be enhanced through pre-processing of the incoming video
using functions such as:
• Support for different resolutions including the standard set of video picture resolutions
(720, 704, 640, 576, 544, 528, 480, 352) in both 625 and 525 line operation.
• An internal frame synchroniser.
• The aspect ratio for the incoming video feed as defined in the VBI, can be maintained in
the output if desired.
• Generation of test patterns to allow the overall system to be tested.
• Replacement of the video stream when input is lost.
• When the SD-SDI input is used, a logo overlay facility is available whereby the Encoder is
configured to overlay a broadcaster’s trademark/logo onto the active video.
Internal Frame Synchroniser
An internal frame synchronizer is provided to accommodate slight differences between the
incoming frame rate and that generated by the stable reference
2
used by the Encoder.
1
Noise reduction is only available when software option EN5900/SWO/NR is purchased.
2
To ensure broadcast quality it is recommended that the studio reference is fed to HYSNC.
In the event of video input loss the Encoder can be software-configured to show either:
• A test pattern (with or without identification text).
• A freeze frame (with or without identification text).
• Cut to a black screen (with or without identification text).
• Drop the video PID if TS encapsulation is active.
1.3.2 HD Video Input (EN8090 Encoder)
The only operational video input is:
• HD-SDI (so named on the back panel) - High Definition Serial Digital Interface that is
compliant to SMPTE 292M.
Video Input Types
The video input frame rate and resolution is user selectable and the available options are
shown in Table 1.3.

1080 x 1920 Interlaced 29.97 frame/s Native SMPTE274M
Video Pre-processing
The efficiency of the encoding can be enhanced through pre-processing of the incoming video
using functions such as:
• Support for reduced horizontal resolution on the encoded video relative to the input video
to reduce the macro-block rate such as resizing from 1920 pixels to 960 pixels for 1080line resolution and resizing from 1280 pixels to 640 pixels for 720-line resolution.
• A downsampler.
• An internal frame synchroniser.
• The aspect ratio for the incoming video feed as defined in the VBI, can be maintained in
the output if desired.
• Generation of test patterns to allow the overall system to be tested.
• Replacement of the video stream when input is lost.
Noise reduction is only available when software option EN8000/SWO/NR is purchased.

An internal frame synchronizer is provided to accommodate slight differences between the
incoming frame rate and that generated by the stable reference
Output on Video Loss
In the event of video input loss the Encoder can be software-configured to show either:
• A test pattern (with or without identification text).
• A freeze frame (with or without identification text).
• Cut to a black screen (with or without identification text).
1.3.3 Video Encoding
H.264/AVC Encoding
Both the EN8030 and EN8090 Encoders can generate a bitstream, from the input video, that
is compliant with the MPEG-4 Part 10 (ISO/IEC 14496-10) specification with a maximum
bitrate of 10.0 Mbit/s for SD operation and 20.0 Mbit/s for HD operation. The H.264/AVC video
encoding functions include.
• Support for the following tools
Spatial Intra prediction: Intra macro-blocks are predicted from surrounding,
previously coded macro-blocks.
Sub-pixel motion vectors: This allows motion to be more accurately represented.

used by the Encoder.
CABAC: Context Adaptive Binary Arithmetic Coding – a more efficient form of
entropy coding compared to traditional variable length codes.
Adaptive GOP structures of IP, IBP, IBBP and IBBBP where the encoder chooses
whether to use B frames according to the video content.
• AUDIO IN2 - This 15-way male D-type connector can be used for the input of up to four
stereo pairs of AES/EBU digital audio when the optional audio encoding daughter card
(EN8000/HDC/AUD) is fitted. Only the input sampling rate of 48 kHz is supported. A
break-out cable is supplied which plugs into this connector and provide s a mo re
convenient means of connecting the audio inputs via five connectors. There are four XLR
female connectors, with the fifth cable being a BNC, which provides an AES/EBU 75 Ω
digital reference output.
• Audio can be de-embedded from the HD-SDI input on the HD encoding card as digital
audio with a sampling rate of 48 kHz. Up to 8 stereo pairs can be extracted from this
interface.
• AUDIO IN - This 15-way male D-type connector is used for the input of up to two stereo
pairs of AES/EBU digital audio or four analogue audio channels. A break-out cable is
supplied which plugs into this connector and provides a more convenient mean s of
connecting the audio inputs via five connectors. There are four XLR female connectors,
with the fifth cable being a BNC, which provides an AES/EBU 75 Ω digital reference
output.
Audio Channels
The HD Encoder has the possibility of two separate audio encoding systems:
• Audio A and B - Audio inputted through AUDIO IN or HD-SDI can be routed to the audio
encoder streams A and B, that can currently implement:
MPEG-1 Layer II (up to two stereo pairs)
Dolby Digital (up to two stereo pairs)
Pass-thru (Dolby Digital and Dolby E)
• Audio 3A, 3B, 3C and 3D - Alternatively if the optional audio encoding daughter card
(EN8000/HDC/AUD) is fitted, audio inputted through AUDIO IN 2 or HD-SDI can be routed
to audio streams 3A, 3B, 3C and 3D, that can currently implement:
MPEG-2 AAC (up to four stereo pairs, or one 5.1 and one stereo pair)
MPEG-4 HE-AAC (up to four stereo pairs, or one 5.1 and one stereo pair)
MPEG-4 HE-AAC v2 (Up to four Stereo Pairs)
Pass-thru (Dolby Digital and Dolby E)
Output on Digital Audio Loss
In the event of loss of digital audio input lock loss the Encoder can be software-configured to
either:
• Code an audio stream of silence
• Remove the presence of the audio PID from the Transport Stream
• Turn off the ASI output of the Encoder
Test Tones
The equipment can be configured to generate a test tone for alignment purposes. Refer to
Annex B, Technical Specification for level and frequency.
Page 1-8 Reference Guide: EN8000 MPEG-4 Part 10 (H.264/AVC) EncodersST.RE.E10233.1
1.4.2 Audio Inputs (EN8030 SD Encoder)
The standard audio input is:
• AUDIO IN2 - This 15-way male D-type connector can be used for the input of up to four
stereo pairs of AES/EBU digital audio when the optional audio encoding daughter card
(EN8000/HDC/AUD) is fitted.
Only the input sampling rate of 48 kHz is supported. A break-out cable is supplied which
plugs into this connector and provides a more convenient means of con necting the audio
inputs via five connectors. There are four XLR female connectors, with the fifth cable
being a BNC, which provides an AES/EBU 75 Ω digital reference output.
• AUDIO IN – 15-way male D-type - software selectable balanced analogue or digital
AES/EBU, with AES/EBU on left only. A break-out cable is supplied which plugs into this
connector and provides a more convenient means of connecting the audio inputs via five
connectors. There are four XLR female connectors, with the fifth cable being a BNC, which
provides an AES/EBU 75 Ω digital reference output.
• Alternatively, audio can be input embedded as AES/EBU on the serial digital interface
(SDI or HD-SDI). Audio may be converted to either of the standard output samplin g
frequencies, 32 kHz or 48 kHz, by use of the built-in asynchronous sample rate
converters. This applies only to audio that is not pre-encoded.
Introduction to the Basic Encoder
Audio Channels
The SD Encoder also has the possibility of three separate audio encoding systems:
• Audio A and B – the audio encoder is capable of processing two stereo pairs inputted
from either an SDI embedded source, a digital source AES/EBU or an analogue source,
termination impedance 600 Ω or 20 kΩ. These are routed to audio encoder streams A and
B that can currently implement:
MPEG-1 Layer II (up to two stereo pairs)
Dolby Digital (up to two stereo pairs)
Pass-thru (Dolby Digital and Dolby E)
• Audio 3A, 3B, 3C and 3D Alternatively, if the optional audio encoding daughter card
(EN8000/HDC/AUD) is fitted, audio inputted through AUDIO IN 2, HD-SDI or SDI can be
routed to audio streams 3A, 3B, 3C and 3D, that can currently implement:
MPEG-1 Layer II (up to four stereo pairs)
MPEG-2 AAC (up to four stereo pairs, or one 5.1 and one stereo pair)
MPEG-4 HE-AAC (up to 4 stereo pairs, or one 5.1 and one stereo pair)
MPEG-4 HE-AAC v2 (up to four stereo pairs)
Pass-thru (Dolby Digital and Dolby E)
Output on Digital Audio Loss
The Encoder can be software-configured, in the event of loss of digital audio input lock loss, to
either:
• Code an audio stream of silence
• Remove the presence of the audio PID from the Transport Stream
• Turn off the ASI output of the Encoder
Test Tones
The equipment can be configured to generate a test tone for alignment purposes. Refer to
Annex B, Technical Specification for level and frequency.
The available audio algorithms that can be used to encode the input audio are:
AAC (MPEG-2 and MPEG-4)
The encoder has the capability of encoding incoming audio using the highly efficient Advanced
Audio Coding (AAC) algorithm. This is the standard WindowsMedia audio algorithm for WM9S
and is commonly known as WMA in the public domain. The sampling rate is restricte d to 48
kHz and the constant bitrate can be varied between 64 kbit/s and 128 kbit/s for a stere o pair of
audio channels.
There is only a single encoding algorithm but there is a menu switches to allow one of main
variants to be selected:
• MPEG-2 AAC: the actual AAC bitstream is compliant to the specification ISO/IEC 13818-7
and is encapsulated in ADTS (Audio Data Transport Stream), which is described in the
same specification. Menu switches have been included to allow the operator to enable an
ARIB-compliant mode.
• MPEG-4 HE-AAC: the actual AAC bitstream is compliant to the High-Efficiency (HE) AAC
profile of MPEG-4 Part 3 as described in ISO/IEC 14496-3. This allows the use of the
Spectral Band Replication (SBR) tool to achieve reasonable results for sub-64 kbit/s
stereo encoding. The minimum bitrate has been restricted so that operation of the encoder
does not use any of the extra tools associated with version 2 of the Profile. The bitstream
is encapsulated in the Transport Stream using LATM/LOAS (Low-overhead Audio
Transport Multiplex/Low-overhead Audio Stream). The implementation is compli ant to
ETSI TS 101 154 V1.7.1 Annex H.
• MPEG-4 HE-AAC v2: The actual AAC bitstream is compliant to the High Efficiency (HE)
AAC v2 profile as described in ISO/IEC 14496-3. This allows both Spectral Band
Replication (SBR) and Parametric Stereo (PS) tools to be used. Operation in this mode is
currently restricted to Stereo at 32 kbit/s.
MPEG-1 Layer II
The Encoder can encode incoming audio at a sampling rate of 48 kHz to an
MPEG-1 Layer II compliant bitstream for TS output only. The available coding modes are:
• Single Mono: either the left or the right channel is encoded - the signal is output to both
XLR connectors at the receiving end. Not available in Linear PCM.
• Dual Mono: the left and right signals are encoded and carried in the transport stream as a
single Packetised Elementary Stream (PES) data stream. The way that the left and right
signals are output from the Receiver is dependent on how the routing is set up on the
Receiver. Both the left and the right may be output, or the left only, or the right only. This is
typically used for multilingual services.
• Stereo: A stereo pair is coded as two mono signals - the two signals are output as stereo
at the receiving end.
• Joint Stereo: A stereo pair is coded taking advantage of the stereo nature of the channels
- the two signals are output as stereo at the receiving end. Available in MPEG-1 Layer II
only.
• Audio Description Service: Signals the presence of an Audio Description Service for the
visually impaired in the PMT.

Introduction to the Basic Encoder
Dolby Digital
If licensed, the Encoder can encode incoming audio at a sampling rate of 48 kHz to a Dolby
Digital compliant bitstream for the TS output only. Dolby Digital audio encoding incorporates
digital normalization, pre-processing (filtering), dynamic range compression and the addition of
bit-stream information. Dolby Pro Logic audio can be carried as ste reo audio through the
Encoder as long as a suitably high bitrate is selected (see Annex B, Technical S pecification).
The available coding modes are:
• 1/0: centre
• 2/0: left and right
Pass-thru
This is where an audio stream has already been encoded e xternally, prior to entering the
Encoder. Currently the Encoder is certified to handle Dolby Digital and Dolby E pre-encoded
streams for TS output only.
NOTES…
1. See Annex F, Audio Modes for details of setting up the audio.
2. The sampling rate for all audio encoders is fixed at 48 kHz.
1.5 VBI Line Processing Modes
With analogue video, ancillary information associated with the video image is encoded within
the vertical blanking interval (VBI) of the video image. However the VBI is not encoded as part
of the active image by the video encoding module for efficiency reasons because the VBI is
not visible to the viewer. So, this information, termed VBI data, must be carried separately in
some other form within the bitstream.
Transport of VBI Data
There are two methods to achieve this:
• Embedding the VBI data within the video elementary stream: all video coding technologies
allow the carriage of user data associated with a video frame with the video frame
bitstream. The following data formats are handled with this method:
Closed Captions and V-chip information stored on Line 21 on top and bottom field of
each frame according to EIA-608 and EIA-708B specifications.
Wide Screen Signalling (WSS) stored on Line 23 according to ETS 300 294 and
signals the aspect ratio of the video image. For H.264/AVC bitstream, the aspect
ratio is contained within the GOP header sequence. Frame accurate switching is
enabled because a GOP header with an accompanyi ng I frame is inserted whenever
this value changes.
• Encapsulating the VBI data within its own elementary stream: the VBI data is contained
separately from any of the other stream. The following data formats are handled with this
method:
Neilson AMOL I and II.
18 lines of Teletext from each field of the video frame can be extracted and
packetised according to DVB specification EN 300 472.
The Encoder has the ability to extract VBI data from line number ranges 10-22 and 272-285
for 525 lines and 6-23 and 318-335 for 625 lines. The specifications surrounding VBI data are
covered in great detail in the Application Note ST.AN.1097 - VBI in TANDBERG Television
Systems.

Teletext Extraction
Line filters can be invoked to selectively disable any individual lines in this range. The filters
are provided to allow the user to ensure that non-Teletext lines (e.g. ITS lines) are not
erroneously extracted. The extracted Teletext lines are formatted into PES packets according
to the DVB specification. The Teletext PES packets are time stamped to allow correct
alignment of subtitling captions with decoded video.
Included as a separate PID.
The following Teletext services are extractable:
• System B (WST) Teletext
