Introduction to the Basic Encoder
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)
·
The MPEG-2 4:2:2
(ISO/IEC 13818)
Video Encoding Modes
Either the 4:2:0 or 4:2:2
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.656-3 (D1 serial format) –
SMPTE 259
·
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. 656-3) 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)
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
·
Selectable bit-rate operation, <1.5 Mbit/s - 50 Mbit/s (see Table 1.3)
·
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

4:2:2 is only available when software option M2/ESO2/422 is purchased.
8
Error detection and handling is not supported in software version 2.0.0.
9
Bit-rates lower than 1.5 Mbit/s are only available when the software option M2/ESO2/PU is purchased.
