Promax Quadruple Video/Audio encoder, multiplexer and DVB-T

The DT-504B module offers the possibility to build a broadcast signal in DVB-T and TS-ASI(*) format from four composite video and audio inputs. It is made of four independent video and audio MPEG-2 encoders and a modulator. Audio inputs can be stereo or mono.

Frequently some TV services are only available as analogue baseband video. That is the case of encrypted programmes which can only be received with a dedicated STB and smart card, signals from CCTV cameras, door entry systems, etc.

By means of the DT-504B modulator, programmes originally in analogue format are inserted to the TV distribution network with the benefits of DVB-T technology.

(*) TS-ASI output optional (option OP-504-S).
