• Manufacturer Part Number: 2452-000-X7R0-471M
• Description: Bcm7400 - Dual Avc/mpeg-2/vc-1 Hd Digital Video Decoder For Satellite, Ip And Cable
• Manufacturer: Broadcom Corp.

The BCM7400 is a dual-channel high definition satellite, cable, and IP set-top
box DVR solution offering integrated AVC (H.264/MPEG-4 Part 10),
MPEG-2, MPEG-4 Part 2, DivX, and VC-1 video decoding technology. It
combines a data transport processor, two high-definition AVC/MPEG-2/VC-
1 video decoders, two advanced-audio decoders, 2D and 3D graphics
processing, high-quality video scaling and motion adaptive deinterlacing,
seven video DACs, dual stereo high-fidelity audio DACs, a dual-threaded
350-MHz MIPS32 with FPU class CPU, and a peripheral control unit
providing a variety of set-top box control functions. The BCM7400 supports
DDR2 memory architectures.
The MPEG-2 DVB-compliant transport stream/PES parser and demultiplexer
is capable of simultaneously processing 256 PIDs via 128 PID channels in up
to six independent external transport stream inputs and four internal playback
channels. All 128 PID channels can be used by the record, audio, and video
interface engine, PCR processing, message filter, and for output via the high-
speed transport or remux module. The data transport module can be
configured to support eight record channels for PVR functionality and six AV
channels to interface to audio and video decoders. 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 BCM7400 features the Broadcom secure processor, providing
secure key generation, management, and protection.
The advanced video decoders featured in the BCM7400 are 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 and playback applications. Tools include additional
transform sizes and spatial prediction modes and support for adaptive
quantization matrix. The video decoders also support high definition VC-1

(Advanced Profile Level 3, Main, and Simple Profiles) and MPEG-2, Main
Profile at Main and High Level. The BCM7400 has two advanced audio
processors 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
PDIF, and two pairs of analog outputs.
High-quality video and graphics processing is integrated, featuring advanced
studio-quality 2D and 3D graphics processing. Also included are motion-
adaptive deinterlacing with 3:2 pull-down, and letterbox detection. Digital
noise reduction minimizes mosquito noise and MPEG artifacts, including
block noise. Picture-in-picture, split picture, and independent picture in
graphics are supported.
The BCM7400 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, 1080i, and
1080p 24/30. Seven output video DACs are available to be shared among the
output functions. The BCM7400 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 BCM7400 incorporates a complete MIPS32-Verified™ microprocessor
subsystem, including caches with bridging to memory and a local bus.
Integrated peripherals include three UARTS, three ISO7816 smart card
interfaces, counter/timers, a GPIO, a LED/keypad controller, IR receivers, an
IR blaster, two UHF remote control receivers, 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 2.0/
1.1 port, two SATA II ports, and an Ethernet port with MAC with integrated
PHY and alternate media independent interface (MII) with overclocking
capability.
