This manual continues to be relevant to subsequent build standards wherethe functionality of the equipment has not changed. Where the buildstandard changes the functionality, a new issue of this manual is provided.

1.2 Role of the MCE

1.2.1 Typical System

The Mobile Contribution Encoder (MCE) is a transportable digital exciter

designed specifically for mobile contribution applications. It is compact andlightweight, fully MPEG-2 and DVB compliant, and has high performancefor the transmission of studio-quality video material. The equipment isdesigned to be suitable for both flyaway use (within an appropriate flightcase) and truck installation.

The Encoder comprises a single video encoder, two stereo audio encoders(dual standard MPEG-1 (layer 2)/Dolby Digital) and general purpose VBIextraction and encoding circuitry.

High quality video encoding is ensured by the inclusion of digital noisereduction techniques and many other proprietary algorithms as well asstandard MPEG compression techniques. Hierarchical motion estimation is

also used.

Video is input to the unit in Composite, Component or serial digital (SDI)format. There is also a logo overlay facility allowing broadcasters totrademark material.

Transponder bandwidth can be traded with video quality by operating thevideo compression bit-rate in the range 1.5 – 45 Mbit/s. Over thisoperating range, encoded video resolution can be controlled in order tooptimise subjective encoding performance.

The MCE encodes up to four channels of audio, which may be configuredas four mono channels or two stereo pairs, input as either analogue or

AES/EBU digital audio.


14/256

Introduction


One channel of asynchronous data and one channel of high speedsynchronous data can also be supported (data channels are notcompressed).

The MCE multiplexes these input signals, under user control, to providesecure programme transmission. The digital stream is then processed forforward error correction (FEC) and modulates a single IF carrier for output

to an Up-converter and High Power Amplifier (HPA) equipment fortransmission to the satellite.

If the Compact Remultiplexing option module is fitted, the MCE is capableof accepting up to three separate transport streams via ASI connectorsand, (together with the host encoder transport stream), provides fourtransport streams multiplexed together. Refer to Figure 1.6 and Chapter 4,Equipment Description for details.

Local control of the equipment is via the front panel keypad and display.The MCE can also be controlled remotely over an Ethernet interface orRS-232/RS-485 port. Local health monitoring is incorporated, along with alocal alarm/fail/reset port.

The equipment is fully configurable and extremely flexible, while still beingsimple to operate and maintain. Various alignment, testing and diagnosticfacilities have been incorporated to assist with operation and maintenancein the field.

• Serial Digital (SDI) – 4:2:2 YCRCB (ITU-R BT. 656-1 part 3) (“D1” serial format), SMPTE-259M.

• Internal test pattern function.

Serial Digital Video Input Error Detection and Handling (EDH)The serial digital video input supports error detection and handling (EDH)as defined by the specification SMPTE RP 165-1994, ‘Error DetectionCheckwords and Status Flags for Use in Bit Serial Digital Interfaces forTelevision’. Refer to Chapter 4, Equipment Description for furtherinformation.

Video Encoding Functions

The standard video encoding functions include:

• Support for all MP@ML standard coding modes, (and 422P@ML, if purchased).

• Selectable bit-rate operation, 1.5 Mbit/s - 15 Mbit/s.• Support for the standard set of video picture resolutions (720, 704,

640, 544, 480, 352 and SIF) in both 625 and 525 line operation.

• Hierarchical motion estimation.• A built in frame resynchroniser to maintain a valid encoded bit-stream

in the event of loss of video.

• Various low delay modes for delay critical applications.• Support for a variety of Group of Pictures (GOP) structures with a

variable number of B frames.

• Built in patented adaptive noise reduction circuitry.• The ability to generate internal video test patterns. These can be

moving, with the ability to load 2 frames.

• A logo overlay facility whereby the MCE is able to overlay broadcaster’slogos onto the active video.

• Various video fail options, eg, freeze frame, cut to black.

Motion Estimation

The MCE uses Hierarchical motion estimation. It takes a macro block (16pixels x 16 pixels) and then performs a series of exhaustive searches for

that block on areas of increasing resolution homing in on an exact match.


17/256

Introduction


Video Variable Bit-rate

The MPEG-2 compression algorithm uses adaptive field/frame coding,forward and backward predictive processing with motion estimation andcompensation to reduce the bit-rate to the range 1.5 to 15 Mbit/s.

NOTE…

If the 4:2:2 upgrade has been purchased, video bit-rates of up to 50 Mbit/s are available on the ASIoutput. The actual modulated output depends on the symbol rate (which has a maximum of 30Msymbols/s).

Coding Resolutions

To provide optimum picture quality over the full bit-rate range, theencoded picture resolution is controlled automatically according to thevideo bit-rate. Alternatively, the user can override this and select manualcontrol, if desired. Available coding resolutions are shown in Table 1.2.

Table 1.2: Video Coding Resolutions and Typical Bit-rates

625 Line Modes 525 Line Modes Typical Bit-rate

4:2:0 (Mbit/s)

Typical Bit-rate 4:2:2 (Mbit/s)

720 pixels x 576 lines 720 pixels x 480 lines 4.0 – 8.0 up to 50.

704 pixels x 576 lines 704 pixels x 480 lines 4.0 – 8.0 up to 50.

544 pixels x 576 lines 544 pixels x 480 lines 2.5 – 6.0 -



System configuration can be stored in non-volatile random access memory(NVRAM) for restoration of configured state at power-on.

Internal Frame Synchroniser

An internal frame synchroniser is incorporated to maintain a valid encodedbit-stream in the event of discrepancies between the relative timing of theinput video syncs and the internal flywheel syncs.

Output on Video Loss

The MCE can be software-configured to show, in the event of video inputloss, either:

• Test pattern• Freeze frame• Cut to a black screen.

1.3.2 Audio Encoding

General

Audio can be encoded to either:

• MPEG-1 Audio (layer 2) standard (sampling rate 32 kHz or 48 kHz).• Dolby Digital (sampling rate 32 kHz, 44.1 kHz or 48 kHz).

Output bit-rate is selectable in the range 32-384 kbit/s (dependent onconfiguration) for MPEG-1 Audio (layer 2) and 56-640 kbit/s(dependent on configuration) for Dolby Digital.


18/256

Introduction


• Pre-compressed (or pre-encoded – IEC 61937) audio in pass-throughmode is also available (it only operates at 48 kHz). This is where anaudio stream has already been encoded externally, prior to enteringthe Encoder, and passes through to the output. This type of audio issupported in Dolby Digital.

NOTE…Motherboard software prior to ver 3.3 included Dolby Digital (AC-3) as part of the standard product.

A separate licence is required from software ver 3.3, this is available from TANDBERG Television.

The input for this type of audio is either via the Serial Digital Input of the audio connector or it can be embedded with the incoming video.

Audio Inputs

The standard audio input is:

• AUDIO IN - 15 way male D-type - software selectable balancedanalogue or digital AES/EBU, with AES/EBU on left only. The rightchannel can be configured to output a reference AES/EBU signal for anexternal Dolby AC-3 Encoder. The audio connector is a 15-way male D-type, but a break out cable is supplied which plugs into this connectorand provides a more convenient means of connecting the audio inputsvia four XLR female connectors.

• Alternatively, audio can be input embedded as AES/EBU on the serialdigital input (SDI). In this mode a maximum of four stereo pairs canbe extracted. Audio may be converted to either of the standard outputfrequencies, 32 kHz or 48 kHz, by use of the built-in asynchronoussample rate converters.

Audio Channels

The MCE supports four channels of audio, which may be configured as:

• Four analogue single mono channels, 600 Ω or 20 kΩ• Two analogue stereo pairs, 600 Ω or 20 kΩ• Two digital channels, AES/EBU or embedded SDI.

MPEG Encoding Modes

The two stereo pairs may be configured in various MPEG-2 encodingmodes:

• Single mono: a mono signal is encoded on the left channel only• Dual mono: the left and right signals are encoded and carried in the

transport stream as a single Packetised Elementary Stream (PES) datastream. The way that the left and right signals are output from thereceiver 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 rightonly. This is typically used for multilingual services

• Stereo: A stereo pair is coded as two mono signals - the two signalsare output as stereo at the receiving end

• Joint/intensity stereo: A stereo pair is coded taking advantage of

the stereo nature of the channels - the two signals are output asstereo at the receiving end.


19/256

Introduction


NOTE…

Joint/intensity stereo is not available in Dolby Digital mode.

Audio Variable Bit-rate

MPEG-1 audio output bit-rate (see Table 1.3) is selectable in the range32-384 kbit/s (dependent on configuration).

Introduction


Dolby Digital (AC-3)

Dolby Digital (AC-3) audio encoding incorporates digital normalisation,preprocessing (filtering), dynamic range compression and the addition of bit-stream information. Dolby Pro Logic audio can be carried as stereoaudio through the Encoder as long as a suitably high bit-rate is selected.

The audio outputs may be configured in single channel mono (1/0) or dualchannel stereo (2/0) encoding mode. The audio output bit-rate isselectable in the range 56 – 640 kbit/s (dependent on configuration). SeeTable 1.4.

The equipment can be configured to generate a test tone for alignmentpurposes. Refer to Annex B, Technical Specification for level andfrequency.

1.3.3 Vertical Blanking Interval Line Processing

Vertical Blanking Interval Line Processing Modes

Introduction

The Encoder has three possible modes for processing Vertical BlankingInterval (VBI) lines.


21/256

Introduction


NOTE…

The following three processing modes are only available if the 4:2:2 upgrade is purchased.

VBI in Picture

By selecting the extended active picture format available in the MPEG4:2:2 specification the MCE compresses and transmits the VBI data as partof the active picture. This mode requires up to 3 Mbit/s of extra bit-rate,depending on the amount and complexity of the VBI present.

NOTE…

VBI in Picture transmits the VBI waveform as part of the picture and as such will be subject to somedistortion. Most analogue VBI types are robust against this type of distortion but others, e.g. videoindex, are intended for SDI transmission and will not survive MPEG coding/decoding in VBI in Picturemode.

VBI in PIDThe MCE has the ability to extract and transmit a wide variety of VBI lineformats. Field Programmable Gate Array (FPGA) circuitry on the front endof the equipment incorporates a number of general purpose line grabbersso that known formats of VBI data can be extracted. Closed caption datatogether with other formats of VBI data such as VITC and VPS are to betransmitted in the user data field of the video.

The following VBI data formats are supported:

• Line 21 data Services EIA-608 (Closed Caption and V-chip)• Neilson AMOL 11

• VITC (EBU and SMPTE)• Programme Delivery and Control PDC, via ITU-R system B Teletext

extension data packets of type 8/30, format 2 and Line 16 VideoProgramming System (VPS). Video Programming Teletext (VPT) andVPS are trade names

• Wide Screen Signalling (WSS) EN 300 294• Test Signals UK-ITS, ITU-R, FCC ITS (inserted at the receiver)• Video Index (for Pan Scan and Aspect Ratio).

Teletext Extraction

The Encoder supports internal Teletext data extraction (Teletext drop)from the VBI of a video input and formats this data into a transportpacket, as specified in the DVB specification.

The MCE can extract up to 18 lines of Teletext from each field of the videoframe. The supported VBI line number range is 10-22 and 273-285 for 525lines and 7-24 and 319-336 for 625 lines. Line filters can be invoked toselectively disable any individual lines in this range. These are provided toallow the user to ensure that non-Teletext lines (e.g. ITS lines) are noterroneously extracted. The extracted Teletext lines are formatted into PESpackets according to the DVB specification. The Teletext PES packets aretime-stamped to allow correct alignment of subtitling captions withdecoded video.


22/256

Introduction


The following Teletext services are extractable:

• WST Teletext• PDC Program Delivery Control• STARTEXT;• Softel Remote Control;

• Night Owl Remote Control;• Studio Talk Back;• Inverted Teletext.

1.3.4 Data Channels

The MCE can provide data channels that operate as bit-pipes between theencoder and decoders. Two types of data channel are supported:

• Synchronous RS-422: one channel is supported at data rates of n × 64 kbit/s (up to 2.048 Mbit/s) or n × 56 kbit/s (up to 1.792 Mbit/s)where n = 32 max.

• Asynchronous RS-232: one channel is supported at baud rates of 1.2 – 38.4 kbaud.

1.3.5 QPSK IF ModulationThe QPSK Modulator Module provides the satellite transmission functionsspecified for MPEG-2 packet signals as defined by the followingspecifications:

• EN 300 421, ‘Digital Video Broadcasting (DVB); Framing Structure,Channel Coding and Modulation for 11/12 GHz Satellite Services’;

• prEN 301 210, ‘Digital Video Broadcasting (DVB); Framing Structure,Channel Coding and Modulation for Digital Satellite News Gathering(DSNG) and Other Contribution Applications by Satellite’.

The modulator module provides QPSK modulation in the frequency range70 MHz ± 20 MHz, and outputs data at a symbol-rate defined by theencoding module. The spectrum of the QPSK signal can be set to Normaland Inverted states. The convolutional FEC rate can be selected fromvalues 1/2, 2/3, 3/4, 5/6, and 7/8. Output power can be programmed inthe range -20 dBm to +5 dBm

1.3.6 Control and Monitoring

Introduction


1.4 Guided Tour

1.4.1 The User InterfaceThe MCE itself provides no controls at the rear panel but there is a statusdisplay and keypad at the front panel. All connectors are provided at the

rear panel. Control and monitoring may be performed in a variety of ways(see Control and Monitoring). Once configured, the system runs withoutthe need for further intervention unless system configuration requirementschange.

1.4.2 LED Colour Coding PhilosophyTwo LED colours are used externally in this equipment:

• Red is used to indicate fault conditions, e.g. a missing or faulty inputsignal. For correct operation, the red LED must be off, although it maybe on briefly during power-up.

•

Green is used to indicate correct conditions and correct systemfunctioning. For normal operation, the green LED must be oncontinuously.

This colour coding principle was devised to facilitate instant perception bythe operator of the equipment's operational status, i.e. the red LED on orthe green LED permanently off indicates a fault condition.

1.4.3 Front Panel Description

Components

The MCE provides a keypad to input data. There are two LED indicators,located on then left of the front panel (see Figure 1.7 ).

Front Panel Status Display and Keyboard

The front panel status display and keyboard are used as a local controlmethod and to set up and configure the MCE (see Chapter 3, Operatingthe Equipment Locally ). They can also be used as quick method foraccessing the status of the equipment. The status display by default showsthe service name of the video channel being encoded, the equipment typeindicator and the alarm fail status.

1.5.1 FunctionsThe MCE is shipped with the Video, Data and QPSK Modulator modulesfitted in slots 1, 2 and 3 respectively. The functionality of the basic MCE

can normally be enhanced with the inclusion of additional modules in slot4. These consist of a horizontally mounted PCB with rear panel connectorspace. At reset, the software of the Motherboard2 detects which modulesare fitted and configures them as necessary. The modules are fitted intothe positions indicated in Table 1.7.

1.5.2 Analogue Video Input(M2/EOM1/VID)

The Video Input Module (S8481) provides the MCE with high qualityanalogue video inputs via three BNC connectors. The input format is eithercomposite video (PAL B/D/G/H/I/M and NTSC-M) or component Y, CR, CB.

The Setup/Video/Source menu associated with this option is described inSection 3.9.3 in Chapter 3. For a specification of this interface see Annex B, Technical Specification.

1.5.3 Frequency Agile QPSK Modulator(M2/EOM1/QPSK2)

The Frequency Agile QPSK Modulator (S10949) is an internal satellitemodulator module. It plugs into the MCE backplane and accepts an MPEG-2 transport stream directly from the Encoder’s internal program Multiplexeror via the RAS scrambling module over a synchronous parallel interface.

The Modulator performs energy-dispersal scrambling, Reed-Solomonencoding, convolutional interleaving, convolutional encoding, symbolmapping, baseband shaping and modulation, in accordance with theEN 300 421 specification.

The Modulator module provides QPSK modulation in the frequency range70 MHz ± 20 MHz, and outputs data at a symbol-rate defined by thesource equipment (Encoder). The spectrum of the QPSK signal can be setto Normal and Inverted states. The convolutional FEC rate can be selectedfrom values 1/2, 2/3, 3/4, 5/6, and 7/8. Output power can be programmedin the range -20 dBm to +5 dBm.

Menus associated with this module are given in Section 3.9.6 in Chapter 3.
