MX-1500 MPEG-2-TS Multiplexer for Terrestrial Digital Broadcasting

MX-1500 MPEG-2-TS Multiplexer For Terrestrial Digital Broadcasting

The MX-1500 is the MPEG-2-TS multiplexer which multiplexes various MPEG-2-TS signals from HDTV/SDTV/1seg encoders, data broadcasting equipments, SI/EPG equipments, subtitle equipments and EMM/ECM equipments, to the ISDB-T frame structure format Broadcasting TS (BTS) signal. The MX-1500 output signals could be switched seamlessly by synchronizing the ISDB-T frame to an external synchronization signal. The MX-1500 is an energy and space saving Eco friendly product.

Feature

Compliant with standard for digital terrestrial TV PSI generation and multiplexing broadcasting (ARIB STD-B31, SBTVD-T N03) The unit multiplexes signals in the ISDB-T frame structure format, adding The unit multiplexes not only the inputted PSI packets but also the transmit control information and outputs the Broadcasting TS (BTS) signal. generated PSI packets based on information from the host controller.

Seamless switch TOT generation and multiplexing

The output signals could be switched seamlessly by synchronizing the The unit generates TOT packets based on time and date information ISDB-T frame to an external synchronization signal. from an external clock equipment and multiplexes them together.

Input bitrate limiter PCR generation and multiplexing

The packets which exceeded input bitrate limiter value don’t affect the The unit generates PCR packets synchronized with an external STC other ports so that it is rejected. sync signal and multiplexes them together.

Input PID filtering and replacement Synchronizing with external signals

For each TS input port, the unit can filter out the undesignated PIDs and The unit synchronizes the transport clock, the STC value, the setting replace each input PID with a new one designated from the host controller. change timing and the ISDB-T frame phase with each external signal.
