Hitachi Ltd prototyped a digital camcorder that can stream HD video on a TV via a wireless LAN and exhibited it for reference at CEATEC JAPAN 2008.

The camcorder can output video recorded on its HDD or video being shot live to Hitachi's TV that supports HDTV. Video selection, playback, stop and other operations can be done using the TV's remote control.

The prototyped camcorder transmits the HD video compressed in the MPEG-4 AVC/H.264 (H.264 hereafter) format through an SDIO standard IEEE802.11g module and delivers it to a TV via an access point.

DLNA is used to deliver already recorded video. Hitachi incorporated DLNA server capability in the camcorder so that it can deliver recorded video to Hitachi's TVs supporting DLNA client capability.

Video being shot live is transmitted using the camcorder's IPTV server capability. It compresses the video into H.264 format in real time and delivers it via a wireless LAN. With an IPTV reception capability compatible with the "acTVila" specification, Hitachi's TVs can receive the video signals.
