The BCM7401 is a high-definition satellite, cable, and IP set-top box 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 MPEG-2 DVB-compliant transport stream/PES 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 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 BCM7401 features the Broadcom secure
processor providing secure key generation, management, and protection.
An advanced video decoder is featured in the BCM7401, 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 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 BCM7401 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
I²S, SPDIF, and one pair 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 BCM7401 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. Six output video DACs are available to be shared
among the output functions. The BCM7401 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 BCM7401 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).
