Method and apparatus for analyzing digital multi-program transmission packet streams |
摘要 |
A method and device for monitoring a multi-program data stream. The data stream preferably contains digital packets multiplexed from different data and control channels. A service information channel or program guide is available from the data stream to identify the various channels and the associated packets in the data stream. The packet stream analyzer verifies the program guide and the contents of the program guide against the packets found in the packet stream. The semantics and sequencing of packets can also be verified. Verification errors can be recorded and displayed via an interface computer.
