Ultra-Low-Delay H.264 Based Wireless HDTV Camera
For existing MPEG-2 based wireless HDTV camera, latency and picture quality is a major issue, and swift improvement is strongly required. Therefore, NHK developed a wireless HDTV camera integrated with ultra-low delay H.264 encoder, as for this solution. By installing board-type ultra-low delay H.264 encoder to compact-type OFDM (Orthogonal Frequency Division Multiplexing) microwave transmitter, 10msec latency and twice of compression efficiency was achieved. As a result, operation of wireless HDTV camera will become the same as any other wired HDTV camera, and no special treatment will be needed. Contribution to various HDTV program is greatly expected for this ultra-low delay H.264 based wireless HDTV camera. In the presentation, a detailed technology and operation image of this camera will be shown.
