2.2.2 HDD BASED TIME SHIFT RECORDING
Hard Disc Drive (HDD) based time-shift systems enable
Personalized TV (PTV) functionality, providing consumers
with new powers of control over what and when to watch
broadcast content. With the audio and video content
recorded digitally, identification, search and retrieval
becomes a `no brainer' task as compared to traditional
VCR functionality. Combine this with electronic program
guides and intelligent control, and the PTV can also
analyse the viewers watching habits to search for
programs likely to be of interest and automatically
recorded in anticipation of the viewers preferences.
Since HDD recorders are closed systems, the recording
format stream can be proprietary. SAA6752HS flexible
multiplexing formats, support a number of recording
stream formats for HDD including MPEG Transport
Stream (TS) or MPEG Packetized Elementary Stream
(PES).
2.2.3 D
IGITAL VCR (DVHS) RECORDING
A DVHS player records streams based on MPEG
Transport Streams (TS) packed in logical tape tracks. The
SAA6752HS output streams are compliant with DVHS
standard requirements.
2.2.4 V
IDEO EDITING/TRANSMISSION/SURVEILLANCE/
CONFERENCING
The SAA6752HS can operate as a stand-alone device in
all above applications. The SAA6752HS' full features and
flexibility allows customers to tailor functionality and
performance to specific application requirements. All
required control settings such as GOP size and bit rate
modes can be selected via I
2
C-bus.
