The included accessories

Signal-350 A/V-COFDM (DVB-T) R86350 encodes input analog audio-video signal into MPEG-2 stream that modulates RF signal in compliance with DVB-T standard (COFDM). The device is intended for use of one source of baseband video signal (CVBS) and baseband audio signal (stereo/two channels). The signals are to be connected via RCA cable.

In the case of a signal source with HDMI output, the suitable device is Signal-751 R86751.

The A/V signal may come from a camera, multimedia player, computer, DVD player, satellite receiver etc. The output RF signal in DVB-T standard can be distributed via coaxial cable in antenna systems as well as can be used as transmission medium in some CCTV systems. The maximum data rate of the output stream is compliant with DVB-T standard (total: 31.68 Mbps; video: 19 Mbps).

Signal-350 R86350 has been equipped with USB port allowing for recording the source material in .ts format and playing back the same or other material prepared in .ts format. The manufacturer provides the suitable software for converting various content such as pictures, music, videos etc. into .ts files. It means that the device can work independently, generating the output DVB-T signal based on the .ts files played back from a USB drive.

The parameters such as output frequency, bit rate of the stream, modulation scheme etc. are set with buttons and shown by the display located on the front panel of the modulator.
