TBS 6004

The TBS-6004 is a DVB-C 4 QAM modulator PCIe card, working as a DVB-C signal generator. It supports to be fed with any DVB resource or other digital resources, and then output DVB-C channels in 4 Frequencies. For example, you can use a TBS DVB-S2 TV tuner card to receive satellite TV channels and then use TBS-6004 modulator card converting these channels into DVB-C coaxial system. TBS-6004 is equipped with a Loop-in interface, which allows to receive DVB-C resources from other devices, and then remix all the different resources into a new DVB-C coaxial system. TBS-6004 provides a very cost-effective solution to transfer other digital resources, like DVB-S2/S, DVB-T2/T, ISDB-T, ATSC or even IPTV resources into an existing DVB-C Coaxial system in hotels, hospitals, or CATV head stations.

How does TBS-6004 work?

The TBS-6004 DVB-C modulator is designed to convert spts/mpts which generated from TBS DVB-S/S2 card, DVB-T2/T card, network IP, or local SPTS file to DVB-C signal. Then you can use DVB-C STB to receive and play the channels directly.

1. Configure input source: 

  • TBS Adapters -> Only DVB-S2/S Card TBS-6904 supported currently.
  • Network TS -> HTTP, UDP, RTP supported
  • Local Files (SPTS) -> Video format: MPEG-1 MPEG-2 MPEG-4 H264 H.265 Audio format: MPEG-1 MPEG-2 AAC_ADTS AAC_LATM A52 (aka AC3)

2. Remux and generate the channels into DVB-C streams: 

  • A TBS-6004 has 4 modulators. As long as the first mod is set with frequency, the other mod will be set automatically by adding 8M one by one.
