| Super Hi-Vision (SHV) broadcasting was brought a step closer to reality with the development of an advanced video compression codec system. This real-time coding/decoding prototype based on the MPEG-4 AVC/H.264 coding scheme* is the first of its kind for SHV video. It estimates the coding complexity for input video before the actual coding process, and it minutely controls the allotment of information. As a result, it can compress data to one hundredth or one two hundredth its original size, while maintaining the quality of the SHV video. |
- It compresses an SHV video signal to 1/100th to 1/200th its original data size.
- Parallel coding units enable real-time coding of 24-Gbps SHV video signals.
- It controls the start time of coding to ensure synchronized operation of multiple coding units.

| We will conduct SHV transmission experiments with this new codec, and we will continue to develop technologies for high-compression, high-quality video coding.
