The BCM7115 is a single-chip set-top box device that combines
the key aspects required for the next generation of set-top boxes
including cost-effective single-chip design, personal video
recording (PVR), communication via DAVIC or other protocol
and support of all major global physical layer standards for
worldwide deployment.
The BCM7115 includes a 1024/256/64-QAM receiver, an
out-of-band QPSK receiver and a QPSK to 256-QAM upstream
burst modulator. All major physical layer standards are supported
for deployment worldwide. The device includes a complete
DAVIC 1.2/1.5 MAC for interactive services.
The BCM7115 also contains a high-performance MIPS32^TM
RISC processor with 8-KB I cache and 8-KB D cache.
The BCM7115 includes a number of peripherals required for
next-generation set-top boxes, including USB host, IDE
controller for connection to disk drives, POD interface for
external conditional access, and a glueless IEEE 1394 interface.
The BCM7115 also contains support for the Broadcom V.90
softmodem.
Onboard descrambling supports all major conditional access
systems and includes 3DES encryption/decryption for PVR.
The BCM7115 also includes a standard definition MPEG-2
video decoder and 2D/3D graphics subsystem. This allows for
the display of studio-quality text/graphics and 3D effects. The
DVB/DCII transport of the device supports PVR. This support
includes time shifting on the program being viewed and
recording of another program, simultaneously.
The BCM7115 represents the most integrated, cost-effective set-
top box single-chip solution incorporating next-generation
requirements including support of multiple middlewares and
applications. It is built on the previous generation of Broadcom
silicon and software to offer a low risk and quick time to market
for interactive broadband set-top boxes.
A full PCM audio engine for mixing sounds into the main audio
stream is also on-chip. Outputs include left and right analog and
SPDIF.
