Abstract
A method for identifying variations introduced in signals transmitted over a signal path, the method comprising sending, over the signal path, one or more test patterns with functional features to a test pattern analyser, wherein said functional features are for determining aspects of variations introduced in the one or more test patterns during transmission over the signal path; and including a data pattern in at least one of the test patterns prior to said sending, said data pattern comprising meta-data on functional features of the at least one test pattern.
Claims18
A method for identifying variations introduced in signals transmitted over a signal path, the method comprising:
- sending, over the signal path, one or more test patterns with functional features to a test pattern analyzer, wherein said functional features are for determining aspects of variations introduced in the one or more test patterns during transmission over the signal path;
- and
- including a data pattern in at least one of the test patterns prior to said sending, said data pattern comprising meta-data on functional features of the at least one test pattern;
- wherein at least one of said one or more test patterns comprises a video test pattern or an audio test pattern.
A system for identifying variations introduced in signals transmitted over a signal path, the system comprising at least one of:
- (i) one or more test pattern generators, configured to:
- generate one or more test patterns with functional features, wherein said functional features are for determining aspects of variations introduced in the one or more test patterns during transmission over the signal path;
- and
- include a data pattern in at least one of the test patterns, said data pattern comprising meta-data on functional features of the at least one test pattern;
- and
- (ii) one or more test pattern analyzers, configured to:
- receive the one or more test patterns from one or more test pattern generators, wherein at least one of the test patterns comprises the data pattern, said data pattern comprising meta-data on functional features of the at least one test pattern;
- and
- determine variations, introduced over the signal path, of the one or more received test patterns by means of functional features of the received test patterns and by means of said data pattern;
- wherein at least one of said one or more test patterns comprises a video test pattern or an audio test pattern.
