XM-1630 マスタ タイトルの書式設定 MPEG-2-TS Multiplexing Board For Terrestrial Digital Broadcasting The XM-1630 is a MPEG-2-TS multiplexing board 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 ISDBT frame structure format Broadcasting TS (BTS) signal. This board can be installed into the XF-730 frame and XF-712 frame.

Input PID filtering and replacement For each TS input port, the unit can filter out the undesignated PIDs and replace each input PID with a new one designated from the host controller. PSI generation and multiplexing The unit multiplexes not only the inputted PSI packets but also the generated PSI packets based on information from the host controller. TOT generation and multiplexing The unit generates TOT packets based on time and date information from an external clock equipment and multiplexes them together. PCR generation and multiplexing The unit generates PCR packets synchronized with an external STC sync signal and multiplexes them together. Synchronizing with external signals The unit synchronizes the transport clock, the STC value, the setting change timing and the ISDB-T frame phase with each external signal. TS compression The unit compresses the broadcasting TS (204 bytes) of 32.5 Mbps into the MPEG-2-TS (188 bytes) of 19.0 Mbps or less. Custom support to the number of input TS signals, sync signals and control signals By changing a rear board depending on application, you can change the number of the corresponding input TS signals, sync signal inputs and control signals.
