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)

·

The MPEG-2 4:2:2

8

profile @ Main Level (422P@ML) specification

(ISO/IEC 13818)

Video Encoding Modes

Either the 4:2:0 or 4:2:2

8

video encoding modes can be selected. The

coding mode selected affects the compression techniques, encoder delay

and rate control.

Video Inputs

The standard video inputs are:

·

SDI - Serial Digital Interface - ITU-R BT.656-4, part 3 (D1 serial

format) – SMPTE 259 (component only)

·

Composite Analogue (PAL/NTSC)

Video Input Types

The video input types which are supported are:

·

625-line composite PAL-B, -D, -G, -H or -I (ITU-R BT. 624-4)

·

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)

The serial digital video input supports error detection and handling (EDH)

9

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 Encoding Functions

The standard video encoding functions include:

·

Support for all MP@ML and 422P@ML

8

standard coding modes

·

Selectable bit-rate operation, <1.5 Mbit/s - 50 Mbit/s (see Table 1.3)

10

·

Support for the standard set of video picture resolutions (720, 704,

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

full and half-vertical resolution in both 625 and 525 line operation

8

4:2:2 is only available when software option M2/ESO2/422 is purchased.

9

Error detection and handling is not currently supported.

10

Bit-rates lower than 1.5 Mbit/s are only available when the software option M2/ESO2/PU is purchased.
