BCM7452 Block Diagram
The BCM7452 is a high-definition satellite, cable, and IP set-top box DVR
solution offering integrated AVC (H.264/MPEG-4 Part 10), MPEG-4 Part 2,
MPEG-2, DivX (3.11, 4.11, 5x), and VC-1 video decoding technology. It
combines a data transport processor, high-definition/standard-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 BCM7452 features the Broadcom secure
processor providing secure key generation, management, and protection.
An advanced video decoder is featured in the BCM7452 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
decode 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 BCM7452 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 BCM7452 has a dual-stream analog video encoder with Macrovision
that supports the following output standards: NTSC-M, NTSC-J, PALBDGHIN, 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, and 576p. Six
output video DACs are available to be shared among the output functions.
The BCM7452 also supports output over an HDMI interface. An ITU-R-656
output port is also available with teletext sideband.
The BCM7452 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, 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, and an Ethernet port with MAC with
integrated PHY and alternate media independent interface (MII).
