Method and system for long term monitoring of video assets

摘要

A method and system for test monitoring video assets provided by a multimedia content distribution network (MCDN) includes an expert test monitoring platform (ETMP) configured to emulate MCDN client systems at a facility of an MCDN service provider. The ETMP may be used to test monitor MCDN performance by acquiring a baseband video signal and performing a test operation. The test operation may involve determining if a video freeze event and/or an audio freeze event has occurred with respect to the baseband video signal. In one example, detection of both an audio and a video freeze event may determine a freeze event for an MHD. After a freeze event is detected, the MHD may be restarted. The freeze event may be logged as a result of the test operation. A predetermined network address may be sent a notification of the freeze alert.

主权项

1. A method, comprising:
requesting a master controller coupled to a video matrix switch for access to a multimedia handling device as an active unit under test, wherein the video matrix switch is coupled to the multimedia handling device and to a plurality of additional multimedia handling devices; obtaining, from the multimedia handling device via the video matrix switch, a video signal including a series of frame images and corresponding audio data output by the multimedia handling device operating as a terminal device of a multimedia content distribution network; recognizing a video freeze event when a difference between two images in the series of frame images is less than a video threshold; recognizing an audio freeze event when a signal power of a portion of the audio data is below an audio threshold; and sending a command to the multimedia handling device responsive to recognizing an instance of the video freeze event coexisting with an instance of the audio freeze event.
