XBT 529 Multiplexer

Broadcast Transport Stream Multiplexer

Multiplexer for 3 layers ISDB-T (188 bytes) which produces a BTS signal (204 bytes). The XBT 529 is a multiplexer designed mainly to perform adaptation of data from TS (ISO/ IEC 13818-1) to BTS (ABNT NBR 15601). The BTS to TS adaptation is provided by BTS to 188 bytes format encapsulation (BTS tunnelling) and a network adapter that generates, from multiple input Transport Streams (TS).
The XBT 529 manages 3 types of inputs: TS, BTS and BTS tunnel. The BTS tunnel is based on MBITL standard defined to enable the data transmission with radio links that allows only the 188 bytes format. In the BTS tunnel output, the BTS 204-bytes data are divided in 184 byte groups and to each group an MPEG-2TS 4 byte header is added.
