BCM7100 SINGLE-CHIP CABLE SET-TOP BOX SYSTEM

B C M 7 1 0 0 F E A T U R E S

A fully featured analog and digital video cable set-
top box feature set in a single chip reduces overall
system cost dramatically.

Subsystems are based on Broadcom's field-proven
production-available technology.

Can be used in cable systems worldwide with DVB,
DAVIC, and ITU standards compatibility.

Broadcom developed device drivers enable rapid
software development cycle with support of
industry-standard operating systems.

Advanced graphics system allows applications such
as internet browsers and electronic program guides
to deliver studio-quality text and graphics on
television monitors.

Includes dual analog and digital (MPEG-2) video
system.

Supports DVS POD requirements.
