Dual-channel IC boosts MPEG-2 encoding

Las Vegas—Targeted at set-top box and personal video recorder applications, Magnum Semiconductor Corp.'s DM8803 dual channel MPEG-2 encoder features a 3D comb filter for improved image quality.

The DM8803 achieves its video quality by pre-processing the image with its TrueView Pro motion-compensated temporal filtering. This helps to alleviate the visual artifacts that often result from poor analog signal (NTSC/PAL) acquisition and transmission. The image is then compressed using Magnum's fifth-generation MPEG technology. A 3D comb filter is used to remove “mosquito noise” from the picture.

The DM8803 accepts two standard 8-bit YUV video inputs, and is able to perform greater than 30 billion operations per second (30 BOPS) for dual A/V compression. It delivers compressed video via a multi-program MPEG-2 transport stream. The device uses standard SDRAM, and features a USB port for expansion.

The DM8803 is packaged in a 388 BGA.

Pricing: $20 for 10,000-piece quantities.
Availability: Samples and production orders.
