In the broadcasting industry, supporting the distribution of high capacity video data (whose resolution is increasing) such as 4K broadcasting has created challenges with regards to transmission bandwidth requirements and increasing running costs for storage consumed by video data.
High compression, high quality, and high resolution encoding of 4K video in real-time with no fluctuations is achieved with Socionext’s codec LSIs, the Multi-Channel Encoder MB86M31 and the Multi-Format, Multi-Channel Codec MB86M30 supporting the leading-edge H.265/HEVC. They also contribute to reducing running costs and power consumption as well as to saving space thanks to their high processing density and Adaptive Bit Rate (ABR) output function.
The M820L comes with fast-speed data processing power including transcoding of compressed video data, abstraction of metadata by real time analysis and integration with the video data. Additionally, it can selectively capture and transmit AV meta data to the cloud for AI and deep learning, making it a suitable for applications that can benefit from such video analysis system include advanced surveillance camera, digital marketing, sports video analysis, and content management in video distribution services of applications.
- Reduction of transmission bandwidth load and amount of storage consumed
Reduction of required transmission bandwidth and amount of storage consumed by more than 50% as a result of pursuing high quality video based on a mean opinion score (MOS) while achieving higher compression
(In HEVC, the 4K60p 4:2:2 10bit video quality required for digital broadcasting can be provided at bitrates from 8 to 30 Mbps)
- Provision of high quality, high resolution video
Provision of high quality, high resolution video enabled by real-time codec with no fluctuations in processing speed
- Support for high dynamic range (HDR)
These codec LSIs support HDR, which significantly enhances the brightness of video. Peak brightness (nit*) can be increased to 100 times that of conventional video. Unlike the synthetic HDR applied for digital cameras, the supported HDR realistically reproduces the various brightness levels existing in the real world for the entire system by subdividing the brightness.
*: Unit of brightness (nit, SI unit symbol: nt)
The MB86M31 is a dedicated H.265/HEVC encoder LSI that compresses high quality, high definition 4K video (4K60p 4:2:2 10bit) required for digital broadcasting at real-time processing speeds with no fluctuation.
The MB86M31 performs simultaneous multi-channel encoding, up to 4 channels for full HD video and 16 channels for SD video. Its 4-chip configuration provides 8K video (8K60p 4:2:2 10bit) encoding at high quality, definition and compression in real-time. With these processing technologies, the MB86M31 can reproduce an exceptional sense of being there and a natural reality, which can only be achieved with 8K video.
- Real-time 4K/8K encoding (up to 4K60p/8K60p)
- Multi-channel* H.265/HEVC encoding
The MB86M30 is developed as a successor of the MB86M31 and inherits the features of the MB86M31. The MB86M30 is a codec LSI that achieves multi format (H.265/HEVC, H.264/AVC and MPEG2) encoding, decoding and transcoding in a single chip.
Those customers who are considering operating a new system along with their existing one (H.264/AVC, MPEG2) can significantly reduce transmission bandwidth requirements and running costs for storage consumption by partially applying the HEVC specification codec while supporting existing systems
- Real-time single chip codec (encoding, decoding, and transcoding)
- Multi-channel* codec/transcode function
- Adaptive bit rate (ABR) function
*: A mix of different resolutions may be used
