| NEC Electronics Corporation has announced
a new audio-visual (AV) codec, the uPD61171, which integrates digital
set-top box (STB) and digital video disk (DVD) recording functions
in a single chip.
The newly developed product features fully integrated back-end
functions of DVD/hard disk drive (HDD) recorders, providing a cost
and space savings by realizing AV compression/decompression and
graphics and video encoding, all on one chip.
The new codec incorporates a dual-CPU architecture using the world's
highest- performance CPU core for DVD recorders. Two 225-MIPS CPUs
are integrated in the chip; one is assigned for audio decompression,
while the other provides processing power for user applications,
including high-quality graphical user interface (GUI) and networking
products.
Two advanced technology attachment (ATA) ports are employed for
up to four HDD/DVD drive connections. This dual-ATA feature, with
the above-mentioned stream processor capability, supports complicated
functions such as time-shifting playback with HDD while programming
on a DVD drive.
