TBS8510-6205-6004 DVB-T2 H.265 AC3 to DVB-C H.264 AAC modulator


TBS8510-6205-6004 DVB-T2 H.265 AC3 to DVB-C H.264 AAC modulator

  • Model: TBS8510-6205-6004
  • Weight: 22,000.00g


The DVB-T2 H.265 AC3 to DVB-C H.264 AAC modulator is combined by a TBS8510 Video transcoder, a TBS6205 DVB-T2 Quad Tuner PCIe Card and a TBS6004 DVB-C Quad Mods modulator PCIe card. It supports to generate around 22 HD DVB-C channels.

Why we need to use this modulator?

Nowadays, more DVB-T2 signal is adopted, especially in EU countries. These kind of DVB-T2 channels are mostly in H.265/HEVC video format and in AC3 audio format.

However, there are still many villages are still with old DVB-T/C system, and not every family has TV sets supporting HEVC and AC3.

In the case, TBS DVB-T2 H.265 AC3 to DVB-C H.264 AAC modulator will help to solve the problem.
