TV networks.

The CX2416x family offers dual MPEG-2 MP@ML video decoders, 32-bit RISC

The CX2416x also features an impressive array of I/O features, including

CX2416x

electronics of dual-TV digital set-top box (STB) for satellite, cable, or terrestrial

encoders, and a set of peripheral I/O ports for STB front and back panel

connectors. The multi-format audio decoder supports MPEG-1, MPEG-2, and

engines for encryption of data to the HDD. This functionality enables

consumers to simultaneously watch and record separate programs, or record

Personal video recorder (PVR) functionality is supported by three dual-stream

transport processors (up to 8 baseband transport stream (TS) interfaces),

fully integrated parallel- and serial-advanced technology attachment (ATA)

interfaces for hard disk drive (HDD) connectivity, and 3DES/AES ciphering
