A New Generation of High-definition Multi-standard Video Decoder supporting AVS standard

【Overview】

The 2nd generation video coding standard with H.264/AVC as representative is the currently popular video coding standard. AVS is 2nd generation video coding standard with independent China intellectual property. The Microsoft VC-1 and MPEG-2 are extensively applied. If a decoder is developed for each standard, to support 4 standards, the device requires 4 decoders, so it increases the device cost much. We developed a full high-definition decoder which can simultaneously support 4 standards and features high integration and low power consumption. Among them, the feature of supporting full HD AVS video decoding is particularly noteworthy, because, at present, most of the other HD chips only support SD AVS decoder.

【Solution】

Analyze common parts of 4 standards, unify the design architect and share computing units and memory units to most extent.

【Technical points】

1. Configurable bitstream parsing unit
2. Configurable decoding unit
3. Reference picture buffer patent technology
4. Variable length code decoding patent technology.

【Effect】

High-definition video decoding: support H.264/AVC Level 4.1 high profile,MPEG-2 HD/SD MP@HL, AVS Jizhun Profile 6.0 and VC-1 AP Level 3.

1080p @ 50/60Hz video output

SoC chip for multi-standard decoder ---- MB86H61 SoC series has been released.
