Abstract
The disclosed embodiments relate to a system and method for inserting sync bytes into a video transport stream. More specifically, there is provided a method comprising determining a parsing procedure supported by a first set top box, appending a first transport packet to comply with the parsing procedure of the first set top box, and transmitting the first transport packet to the first set top box.
Claims12
A method for processing transport packets in a gateway device, the method comprising:
- maintaining a list of parsing procedures for a plurality of set top boxes, each parsing procedure identifying a sync symbol and packet length of a transport packet recognized by a particular set top box;
- determining a parsing procedure supported by a first set top box from the list of parsing procedures;
- appending a first transport packet to comply with the parsing procedure of the first set top box;
- transmitting the first transport packet to the first set top box;
- determining a parsing procedure supported by a second set top box from the list of parsing procedures;
- appending a second transport packet to comply with the parsing procedure of the second set top box, wherein the parsing procedure of the second set top box is different from the parsing procedure of the first set top box;
- and
- transmitting the second transport packet to the second set top box.
