Highly programmable system multiplexing processor
鈥?Ability to multiplex up to four inputs to one or two multiplexed
streams
鈥?CBR/VBR Program/Transport stream multiplexing
鈥?User data / VBI insertion
鈥?Programmable stream parameters
single chip drastically reduces overall system and
development costs.
Dual encoder enables simultaneous time shifting of one
channel and recording of another channel.
Video/audio elementary, video/audio packetized
elementary, program, and transport streams generated
internally to the BCM7041.
Broadcom fourth generation production/field-proven
and in-production technology.
Universal compatibility through standards compliance:
Meets key video encoding (ISO/IEC 13818-2), audio
encoding (ISO/IEC 11172-3, MPEG-1, Layer II and
Dolby digital AC-3) and system multiplexing
(ISO/IEC 13818-1).
Broadcom-developed reference design kit includes
application board, sample application, and drivers
based upon industry-standard operating systems,
enabling rapid and streamlined software and
hardware development, reducing time to market.
Simple system design: BCM7041 + 1 or 2 modules
SDRAM.
