Panasonic Amazing HDR Like Portable TV

Category: Image - Tags: Digital, Hdr, Oled, Panasonic, Tuner, Tv

I admit I’m impressed with this new Panasonic TV and its HDR like TV tuner. The TH-L17F1, is an average 17” OLED backlight TV portable equipped with an IPV panel and a 1366×768 resolution, featuring four antennas that behave like a DLSR when it comes to HDR (High Dynamic Range).

These antennas all capture the same TV channel, four different image qualities from four sub channels… Mix all them together for the clearest picture possible (see graphic below). The TV uses Japanese Terrestrial Digital Broadcasting, the only way for Panasonic to use this HDR like system.

This technique provides the best TV quality anywhere you are.

Note: HDR is different from Panasonic’s “antenna diversity”, but it may give you an idea of what we’re talking about if “antenna diversity” doesn’t ring a bell.

This is called antenna diversity, not HDR, simply because the dynamic range is the same in all images, contrary to what happens in photography.

I use the HDR as a reference, I thought that this will be easier for people to understand

Antenna diversity techniques can also be used with the European/Aus/NZ DVB-T system, which like ISDB-T, uses COFDM transmission. Quite a few PC DVB-T tuners allow you to merge two tuners into one “diversity” tuner using the same techniques. When you’re travelling, using a pair of whip antennae can massively improve your signal quality. I’ve used my Hauppauge Nova-DT Stick on many occasions to get digital TV in hotel rooms on my laptop using diversity. Haven’t seen it in TVs in Europe yet – probably because many European homes have rooftop aerials.

Wouldn’t you need separate sources to get any meaningful diversity? Or at least decent spacing between receivers?

Also, do you need digital transmission to do it?
