Toshiba introduces in Japan a small portable digital TV receiver and video viewer.

Update:
The altavista translation made me first think its a satellite TV receiver, but its the digital terrestrial broadcasting in Japan or also called mobile broad-casting. Anyway only works in Japan.

The Toshiba MTV-S10 has a 3.5" TFT color screen with a QVGA resolution. It can receive the Japanese digital TV Channel モバHO! (altavista does not translate the name) from the Mobile Broadcast company.
The Toshiba MTV-S10 has access to EPG for users to select a video or audio channel. The MTV-S10 can also record video and audio to SD-Memory Cards. The Portable Digital TV can also playback MP4 video like a normal Portable Video Player. The Toshiba MTV-S10 measures 99.8x112x31.9mm. The handheld Satellite TV will go on sale in Japan on November 1st.
