Sharp Corp will introduce into the Japanese market a new receiver tuner module for One-Seg digital terrestrial broadcasts capable of receiving two One-Seg programs simultaneously. Mass production of the model VA3A5JZ923 begins Monday.
In Japan, the percentage of mobile handset shipments with the capability to receive One-Seg programs exceeded 85% in December 2008. Now, manufacturers are seeking new added-value receiver functions in their efforts to differentiate their handsets in a competitive market environment.
The VA3A5JZ923 combines two tuner ICs with two OFDM demodulation ICs to allow two One-Seg broadcast programs to be received simultaneously, enabling such features as dual-screen display, or background recording of another program on a different channel.
In addition, the VA3A5JZ923 supports diversity techniques to improve reception performance. In diversity mode, when receiving only a single broadcast channel, the signals received from the two tuners are combined to provide the optimal (most stable) video reception in the mobile environment. This enables a higher reception sensitivity of 112 dBm, a 3 dB improvement over its predecessor. Plus, Sharps proprietary high-density surface mount technology makes possible a compact package design measuring only 9.0 x 9.0 x 1.25 mm.

9.0 x 9.0 x 1.25 mm is a huge package size for a mobile phone, plus 1-seg reception is non-existent and/or totally sucks. I don't know why they are bothering - even if the reception is improved the contents are rubbish. Mobile TV has been around for over twenty years and has never really caught on.

I have no clue as to what a seg is.

Here in Sapporo, the regular analog signal is much better than the 1-seg, which is weak and spotty at best. Totally useless technology outside of Tokyo, is my guess. Isn't the real market for this the train commuters in Tokyo? I can't be bothered to turn on my TV to watch one channel, let alone get a phone that can receive two!
