Abstract
A method and system for 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 obtain remote control response metrics, along with internal performance data, for client systems in the ETMP. Historical metrics and historical data may be logged along with the release version for the client systems, which may then be used to correlate operational performance when analyzing client system characteristics.

1-20. (canceled)
A method, comprising:
- acquiring a baseband video signal output by a multimedia handling device installed in a test monitoring platform of a multimedia content distribution network responsive to receiving first user input selecting the multimedia handling device;
- generating a remote control command;
- and
- analyzing the video frames and corresponding timestamps to determine a remote control response metric indicative of a response time of the multimedia handling device to the remote control command.
A test monitor platform, comprising:
- a processor;
- a network adapter accessible to the processor;
- a computer readable storage medium, including stored processor-executable instructions, which when executed by the processor cause the processor to perform operations comprising:
- sending the remote control command to a multimedia handling device coupled to the testing monitoring platform;
- receiving a baseband video signal output by the multimedia handing device, wherein the signal includes a series of video frames;
- and
- determining, based on the video frames and corresponding video frame timestamps, a video performance metric indicative of a remote control command response time of the multimedia handling device to the remote control command.
A computer readable memory media including stored processor executable instructions, which when executed by the processor, cause the processor to perform operations including:
- receiving a baseband video signal from a multimedia handling device, the based band video signal including a series of video frames;
- responsive to receiving user input for controlling multimedia output presented by the multimedia handling device, sending a remote control command corresponding to the user input to the multimedia handling device;
- obtaining a first timestamp when the remote control command is sent;
- monitor the baseband video signal for an expected video frame associated with the remote control command;
- when the expected video frame is detected, obtain a second timestamp associated with the expected video frame;
- and
- record a response time for the multimedia handling device corresponding to a difference between the second timestamp and the first timestamp.
