How to distribute a High Definition TV channel (HDTV) at home

Description: 

So far, the distribution of a high definition video source in TV show rooms of large Shopping Centers, was possible only through the distribution by means of splitters and HDMI cables, then only visible to TV with HDMI input.

Today, thanks to COFDM modulator DigiSlot (Ref. 554501) and HDMI Encoder (Ref. 554803), you can deploy  HD content on a RF coaxial network by connecting the HDMI output of the device that generates or receives this signal (PC, BluRay, TVSAT receiver, etc.) to the HDMI input of this encoder, by keeping the original quality (HD or 3D) on all television with integrated DTT HD (MPEG4).

If we need to receive this content on the TV of the showroom, even without an MPEG4 chip, a solution may be to create a SD version of this signal by extracting of A/V signals from the source device and sending them to the A/V Encoder (Ref. 554801) which will generate a DTT MUX output  with the SD version of the HD source.

For these situations, Televés offers its DigiSlot COFDM modulator together with the HDMI Encoder Ref. 554803. By using these two devices,  it is possible to deliver the original signal quality (HD or 3D) for all television sets.

.

In this way, all the TVs will receive a COFDM multiplex providing two TV channels containing the output of our source: one HDTV and one SDTV. The MPEG4 TV set can display HD content, while those with MPEG2 only will display the standard definition
