Abstract
A method, system, and computer-readable medium for facilitating integrity verification of a transport stream is provided. Integrity verification is performed without increasing the bit rate of the transport stream by generating a checksum corresponding to a portion of the transport stream and inserting the checksum into a null packet within the transport stream. Utilizing a null packet to carry the checksum allows the checksum to be transmitted without increasing the bit rate of the transport stream. In addition, by creating a checksum corresponding to a portion of the transport stream, integrity verification may be performed on a streaming data file.
