Security features on MPEG decoder prevent piracy

Santa Clara, Calif. — To prevent the piracy of digital broadcasts on pay television, NEC Electronics America, Inc. rolled out a single-chip MPEG decoder with enhanced security features for digital set-top boxes (STBs).

NEC has incorporated features specifically designed to prevent the illegal reception and
copying of pay TV broadcasts and information stored in STBs.

The μPD61126 decoder integrates two MIPS32 4KEc microprocessor cores capable of delivering speeds up to 286 mips each. The decoder also offers an improved DDR-SDRAM interface, with speeds up to 333 MHz and memory up to 1 Gbyte.

An enhanced graphics engine provides designers with more flexibility to manipulate advanced graphics and data. The combination of these performance-enhancing features enables smooth operation of the Multimedia Home Platform (MHP), outstanding speed in
interactive Multimedia and Hypermedia Experts Group (MHEG) applications, and
integration of standard on-screen display functions, said Masao
Hirasawa, NEC's general manager, Digital AV Systems Division.

An embedded USB 1.1 host interface permits connection to external devices such
as cable modems or digital cameras, and direct support for Digital Video
Broadcasting-Common Interface (DVB-CI) standards eliminates the need for external
routing chips. In addition to these functions, the device has comprehensive
power management functions and a design process optimized for low-power
operation. The μPD61126 decoder also enables maximum reuse of hardware and
software components from field-proven devices to facilitate speedy migration
from legacy devices.

The decoder is supported by a range of software and middleware,
including reference designs, evaluation systems and a full suite of high-level
application program interfaces (APIs) and wrappers that are compatible among all
of NEC Electronics' digital AV devices.

Volume production is slated for early next year. Samples of the μPD61126 decoder are available today and are priced at $25.00 each Click here for the μPD61126 data sheet.
