Hardware Configuration

Each piece of hardware has a specific reference number. These are linked

to give a hardware configuration number (see Figure 1.4) for the whole

unit. The first part of the number refers to the enclosure and any

mandatory modules, and each subsequent part refers to an option module.

Refer to Table 1.7 for the positions of each option module.

Build Revision

The build revision number (see Figure 1.4) refers to the physical status of

the enclosure and any option modules at the time the equipment was

shipped from the factory.

Firmware / Software Versions

This manual has been written to cover the functionality of the firmware

versions which are contained within the build standard identified on the

information label (see the rear of the Encoder and also Figure 1.4).

This manual continues to be relevant to subsequent build standards where

the functionality of the equipment has not changed. Where the build

standard 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 and

lightweight, fully MPEG-2 and DVB compliant, and has high performance

for the transmission of studio-quality video material. The equipment is

designed to be suitable for both flyaway use (within an appropriate flight

case) 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 VBI

extraction and encoding circuitry.

High quality video encoding is ensured by the inclusion of digital noise

reduction techniques and many other proprietary algorithms as well as

standard 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 to

trademark material.

Transponder bandwidth can be traded with video quality by operating the

video compression bit-rate in the range 1.5 – 45 Mbit/s. Over this

operating range, encoded video resolution can be controlled in order to

optimise subjective encoding performance.

The MCE encodes up to four channels of audio, which may be configured

as four mono channels or two stereo pairs, input as either analogue or

AES/EBU digital audio.

Introduction

Page 1-6 Instruction Manual: evolution 5000 E5500 Mobile Contribution Encoder

ST.TM.E10033.3

One channel of asynchronous data and one channel of high speed

synchronous data can also be supported (data channels are not

compressed).

The MCE multiplexes these input signals, under user control, to provide

secure programme transmission. The digital stream is then processed for

forward error correction (FEC) and modulates a single IF carrier for output

to an Up-converter and High Power Amplifier (HPA) equipment for

transmission to the satellite.

If the Compact Remultiplexing option module is fitted, the MCE is capable

of accepting up to three separate transport streams via ASI connectors

and, (together with the host encoder transport stream), provides four

transport 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 or

RS-232/RS-485 port. Local health monitoring is incorporated, along with a

local alarm/fail/reset port.

The equipment is fully configurable and extremely flexible, while still being

simple to operate and maintain. Various alignment, testing and diagnostic

facilities have been incorporated to assist with operation and maintenance

in the field.

1.3 Summary of Features

1.3.1 Video Encoding

MPEG-2 Encoding

The encoder processes a broadcast-standard video signal into a

compressed encoded bit-stream in accordance with:

• The MPEG-2 Main profile @ Main level (MP@ML) specification (ISO/IEC

13818); or

• The MPEG-2 4:2:2 Profile @ Main Level (4:2:2P@ML) specification

(ISO/IEC 13818).

NOTE…

The 4:2:2 option will only be available if purchased as an option.

Video Encoding Modes

Either the 4:2:0 or 4:2:2 video encoding modes can be selected. The

coding mode selected affects the compression techniques, encoder delay

and rate control.

• 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’s

logos 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 (16

pixels 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.

Video Variable Bit-rate

The MPEG-2 compression algorithm uses adaptive field/frame coding,

forward and backward predictive processing with motion estimation and

compensation 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 ASI

output. The actual modulated output depends on the symbol rate (which has a maximum of 30

Msymbols/s).

Coding Resolutions

To provide optimum picture quality over the full bit-rate range, the

encoded picture resolution is controlled automatically according to the

video bit-rate. Alternatively, the user can override this and select manual

control, if desired. Available coding resolutions are shown in Table 1.2.

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 encoded

bit-stream in the event of discrepancies between the relative timing of the

input video syncs and the internal flywheel syncs.

Output on Video Loss

The MCE can be software-configured to show, in the event of video input

loss, 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 on

configuration) for MPEG-1 Audio (layer 2) and 56-640 kbit/s

(dependent on configuration) for Dolby Digital.

Introduction

ST.TM.E10033.3

• Pre-compressed (or pre-encoded – IEC 61937) audio in pass-through

mode is also available (it only operates at 48 kHz). This is where an

audio stream has already been encoded externally, prior to entering

the Encoder, and passes through to the output. This type of audio is

supported 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 balanced

analogue or digital AES/EBU, with AES/EBU on left only. The right

channel can be configured to output a reference AES/EBU signal for an

external 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 connector

and provides a more convenient means of connecting the audio inputs

via four XLR female connectors.

• Alternatively, audio can be input embedded as AES/EBU on the serial

digital input (SDI). In this mode a maximum of four stereo pairs can

be extracted. Audio may be converted to either of the standard output

frequencies, 32 kHz or 48 kHz, by use of the built-in asynchronous

sample 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 encoding

modes:

• 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) 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/intensity 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.

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 range

32-384 kbit/s (dependent on configuration).

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 stereo

audio 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 dual

channel stereo (2/0) encoding mode. The audio output bit-rate is

selectable in the range 56 – 640 kbit/s (dependent on configuration). See

Table 1.4.
