FEATURES
1.1
Video input and preprocessing
Digital YUV input according to “ITU-R BT.656”(8 bits at
27 MHz) and “ITU-R BT.601”
Support of enhanced “ITU-R BT.656”input format
containing decoded VBI data readable via I
2
C-bus;
Closed Caption (CC), Wide Screen Signalling (WSS)
and copyright information with Copy Generation
Management System (CGMS)
Processing of non-broadcast video signals from analog
VCR according to IEC 756
Two video clock input pins for switching two digital video
sources
“ITU-R BT.601” format conversion to 1/2D1, 2/3D1 and
Standard Interchange Format (SIF)
4 : 2 : 2 to 4 : 2 : 0 colour format conversion
Decimation filtering for all format conversions
Adaptive median filter and motion compensated filter for
input noise reduction.
1.2
Video compression
Real-time MPEG-2 encoding compliant to Main Profile
at Main Level (MP@ML) for 625 and 525 interlaced line
systems
Supported resolutions: D1, 2/3D1, 1/2D1 and SIF
IPB frame, IP frame and I frame only encoding
supported at all modes
Supported bit rates: up to 25 Mbit/s I-only encoding;
up to 15 Mbit/s IP-only or IBP encoding.
Variable video bit rate mode for constant picture quality
and constant bit rate mode to gain optimum picture
quality from a fixed channel transfer rate
Access to bit rate control parameters whilst encoding to
support external real-time control algorithms (e.g.
constrained variable bit rate control)
Programmable Group Of Pictures (GOP) structure
Innovative motion estimation with wide search range
Adaptive quantization
Motion compensated noise filter.
1.3
Audio input
Audio inputs: I
2
S format or EIAJ format (16, 18 or
20 bits), master or slave mode at 32, 44.1 and 48 kHz
Two digital I
2
S input ports for selection between two
digital audio sources
Audio clock generation: 256f
s
or 384f
s
(where
f
s
= 48 kHz) locked to video frame rate (if video is
present and locking is enabled)
Sample rate conversion to 48 kHz (locked to video
frame rate if enabled) for slave mode operation in all
modes except Digital Versatile Disc (DVD) compliant
bypass.
1.4
Audio compression
Dolby
(1)
Digital Consumer Encoding (DDCE) also
known as AC-3
(2)
2 channel audio encoding at
256 kbit/s or 384 kbit/s (only for SAA6752HS/V103)
MPEG-1 layer 2 audio encoding at 256 kbit/s or
384 kbit/s
Input data bypass for Linear Pulse Code Modulation
(LPCM) and compressed audio data [MPEG-1,
MPEG-2, Dolby
Digital (DD) and Digital Theatre
System (DTS)] according to IEC 61937
Preamble Pc, Preamble Pd and bit stream information
captured for identification of modes during bypass of
compressed audio data for MPEG-1, MPEG-2, DD and
DTS according to IEC 61937
Audio mute via I
2
C-bus control for all modes except
DVD-compliant bypass.
