Re-Multiplexing ISDB-T BTS Into DVB TS for SFN

The Single Frequency Network (SFN) allows a single TV channel to cover a great area in the same frequency, increasing the spectrum efficiency and signal quality. In this case, all the programs are re-multiplexed into a Transport Stream (TS) and distributed to the re-transmitter stations. The Integrated Digital Services Broadcasting-Terrestrial (ISDB-T) has been projected to operate in SFN, and uses a TS-adapted version called Broadcast Transport Stream (BTS). The BTS has a constant bit rate and packet size of 204 bytes. Owing to these characteristics, most network adapters are non compliant with this signal type. This article proposes a new re-multiplexer algorithm of the BTS signal that allows the encapsulation of the BTS into the Digital Video Broadcasting Transport Stream (DVB TS) and vice versa. This technique makes the BTS distribution possible through satellite, allowing the large SFN construction and accomplishing lesser bit rate than the original BTS.
