For high-quality compressed transmission
We have developed an 8K video decoder that is compatible with the previous 8K video encoder using MPEG-H HEVC/H.265*1. The encoder and decoder enables real-time encoding and decoding of 8K video, which contains massive amounts of data.
We have developed an audio encoder/decoder using MPEG-4 AAC*2 supporting 22.2 ch sound and a multiplexing/demultiplexing capability using MPEG-H MMT*3 to combine and transmit compressed video and audio data.
The video coding, audio coding, and multiplexing schemes comply with the domestic standard ARIB STD-B32 ver. 3.1*4, which was revised in December 2014.
We will verify the operation of the devices by conducting transmission experiments using an actual broadcasting satellite. We are also continuing with development of 8K video encoder/decoder capable of a 120-Hz frame frequency.
