Abstract
A method and test instrument for validating MPEG content in a CATV network, particularly one having a Remote PHY architecture.
Claims20
A method for testing Moving Picture Experts Group (MPEG) content transmitted to a downstream portion of a cable television network, said method comprising:
- obtaining a logical channel plan comprising logical channels;
- obtaining MPEG data on each physical channel within the MPEG content and performing an analysis and accounting of the MPEG data to identify programs, elementary streams and associated packet identifiers (PIDs) of said programs, and a count of a number of times PIDs were repeated within an analysis duration;
- validating the logical channel plan against the analyzed MPEG data;
- and
- determining if each logical channel is present and properly formed.

A computing device for testing Moving Picture Experts Group (MPEG) content transmitted to a downstream portion of a cable television network, said computing device comprising:
- a storage device;
- and
- a processor executing program instructions stored in the storage device and being configured to:
- obtain contiguous MPEG data from an MPEG transport stream;
- obtain a logical channel plan;
- determine whether first content within the MPEG transport stream matches content within the logical channel plan;
- determine whether second content within the MPEG transport stream is associated with third content within the MPEG transport stream;
- and
- validate the MPEG content when it is determined that the first content matches the content within the logical channel plan and when it is determined that the second content is associated with the third content.
