Transmodulator 4xDVB-S/S2/S2X Multistream – 2xDVB-T/C TMS-204 FTA ALCAD

View of the TMS-204 transmodulator

The TMS-204 R82616 transmodulator is a device enabling distribution and management of satellite TV content in a private TV system. The TMS-204 R82616 module is used to convert a DVB-S/S2 signal into a DVB-T/DVB-C signal. The device is capable of receiving "multistream" signals and enables reception of free-to-air channels. One panel TMS-204 R82616 receives the entire signal package from four satellite transponders and creates two adjacent DVB-T (max. capacity 31.68 Mbps) or DVB-C (max. capacity 53 Mbps) multiplexes. In practice, this means several channels in standard SD/HD resolution for each multiplex. The system administrator selects the channels of interest from a given satellite stream and then creates two adjacent DVB-T/C multiplexes. When remultiplexing the streams, a safety margin of 10% should be kept in mind when determining the maximum bit rate for the entire multiplex. If the limit is exceeded, it is possible to feed the signal to further TMS-204 R82616 modules. The digital DVB-T/C signal available at the output is supplied to the end receivers, usually with the use of splitters/tappliers. Such a solution works best in modern hotel systems, distributing high-quality programmes, including high-definition HD channels.

In the case of introducing coded channels into the TV system, it is recommended to install the TMS-214 R82614 panel.
