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).
