Field, 16x8, and frame-mode prediction for superior

video quality

Integrated programmable video pre- and post-

processors, including noise-reduction and

deblocking filters

Integrated temporal filter and telecine functions

Programmable VBI extraction

Hardware-based cipher engine for content protection

of recording media (CPRM)

1.8V and 3.3V power supplies, 5V I/O tolerant

channel audio using either the Dolby

Consumer Encoder (DDCE) or MPEG audio,

including MP3

Digital

The new CS9268X is a family of single-chip, real time MPEG-2 audio and

video encoders with an integrated DV decoder, DV to MPEG transcoder,

system multiplexor, programmable VBI extraction, and a rich set of inter-

faces, such as IDE and IEEE 1394 link-layer A/V interface. The CS9268X

family is designed for digital video recording systems, such as DVD

recorders, personal video recorders, and advanced set-top boxes, as well as

home media centers.

These devices integrate all the features of the CS92288 MPEG-2 audio/video

encoder plus:

By integrating advanced MPEG-2 features, such as support for both frame

and field prediction, and proprietary rate control algorithms, these

processors provide high video quality at both low and high bit rates.

IEEE 1394 link-layer A/V interface

DV to MPEG transcoding

Hardware-based cipher engine for content protection (CPRM)

Dedicated, bi-directional, serial or 8-bit parallel transport stream

interface (BGA packages only)

Programmable VBI extraction

Serial Bus Interface (BGA packages only)

IDE Interface (BGA packages only)
