• Manufacturer Part Number: BCM7402
• Description: AVC/MPEG-2/VC-1 HD DIGITAL VIDEO SYSTEM-ON-A-CHIP SOLUTION
• Manufacturer: Broadcom Corporation

The BCM7402 is a high-definition satellite, cable, and IP set-top box non-
DVR solution offering integrated AVC (H.264/MPEG-4 Part 10), MPEG-2,
and VC-1 video decoding technology. It combines a data transport processor,
high-definition AVC/MPEG-2/VC-1 video decoder, advanced-audio decoder,
2D graphics processing, high-quality video scaling and motion adaptive
deinterlacing, six video DACs, stereo high-fidelity audio DACs, a MIPS32/
MIPS16e™ class CPU, and a peripheral control unit providing a variety of
set-top box control functions.
The M P EG-2 D VB -compliant transport stream /P ES parser and
demultiplexer is capable of simultaneously processing 256 PIDs via 128 PID
channels in up to five independent external transport stream inputs and two
internal playback channels. All 128 PID channels can be used by the record,
audio, and video interface engine (RAVE), PCR processing, message filter,
and for output via the high-speed transport or remux module. The transport
provides 1DES/3DES/DVB/Multi2/AES descrambling support. A memory-
to-memory DMA security module may be programmed for supporting AES/
1DES/3DES/CSS/CPRM/CPPM/DTCP copy protection algorithms/
standards. The BCM7402 features the Broadcom secure processor providing
secure key generation, management, and protection.
An advanced video decoder is featured in the BCM7402, capable of
supporting high-definition AVC, VC-1, and MPEG-2 streams. AVC support
is for main- and high-profile to level 4.1 for 720p and 1080i high-definition
support or to level 3.1 for standard definition streams. AVC high profile was
added to the fidelity range extensions specifically to address the needs of
consumer broadcast applications. Tools include additional transform sizes
and spatial prediction modes and support for adaptive quantization matrix.
The video decoder also supports high-definition VC-1 (advanced-profile
level 3, main, and simple profiles) and MPEG-2, main profile at main and

high levels. The BCM7402 has an advanced audio processor capable of
decoding Dolby Digital, Dolby Digital Plus, AAC 5.1, AAC+ level 2, and
MPEG 1 layers 1, 2, and 3 with simultaneous pass-through support. 3D SRS
audio is also supported. Available audio outputs are I
of analog outputs.
High-quality video and graphics processing is integrated, featuring advanced
studio quality 2D graphics processing. Also included are motion-adaptive
deinterlacing with 3:2 pulldown, and letterbox detection. Digital noise reduction
minimizes mosquito noise and MPEG artifacts, including block noise.
The BCM7402 has a dual-stream analog video encoder with Macrovision
that supports the following output standards: NTSC-M, NTSC-J, PAL-
BDGHIN, PAL-M, and PAL-Nc. The following output formats are
supported: composite, S-Video, SCART, RGB, and YPrPb component. The
following output resolutions are supported: 480i, 480p, 576i, 576p, 720p, and
1080i. Six output video DACs are available to be shared among the output
functions. The BCM7402 also supports output over an HDMI interface and
a channel 3/4 RF modulator. An ITU-R-656 output port is also available with
teletext sideband.
The BCM7402 incorporates a complete MIPS32™-based microprocessor
subsystem, including caches with bridging to memory and a local bus.
Integrated peripherals include three UARTS, two ISO7816 smart card
interfaces, counter/timers, a GPIO, a LED/keypad controller, IR receivers, an
IR blaster, a UHF remote control receiver, an integrated soft modem system
side device, and BSC and SPI controllers. Advanced connectivity features
include two USB 2.0/1.1 ports, an additional independent USB 1.1 port, a
serial ATA port, and an Ethernet port with Mac with integrated PHY and
alternate media independent interface (MII).
