Abstract
A method and test instrument for validating MPEG content in a CATV network, particularly one having a Remote PHY architecture.
Claims20
A computing device for testing Moving Picture Experts Group (MPEG) content transmitted to a cable television network, said computing device comprising:
- a processor configured to:
- obtain MPEG data on each physical channel within the MPEG content;
- perform an analysis 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;
- validate a logical channel plan comprising logical channels against the analyzed MPEG data;
- and
- determine if each logical channel is present and properly formed.
3 more elements
A method for testing Moving Picture Experts Group (MPEG) content transmitted to a downstream portion of a cable television, said method comprising:
- determining whether first content within an MPEG transport stream matches content within a logical channel plan;
- determining whether second content within the MPEG transport stream is associated with third content within the MPEG transport stream;
- and
- validating 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.
