  • Publication number: 20140160302
    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 test monitor MCDN performance by acquiring a baseband video signal and performing a test operation including at least one check point condition. The check point condition may be associated with a masked region of the video signal and may also involve a test of an audio channel. A plurality of test operations and/or check point conditions may be defined and executed on the baseband video signal, while the results of the test operation may be logged.

  • Patent number: 8661487
    Abstract: A control server receives a local input to control a remote video device and sends an indication of the local input to the remote video device to control, access, or operate the remote video device. Video data indicative of images provided by the remote video device in response to the local input are relayed to the control server by the remote video device or associated components. A plurality of remote video devices can be simultaneously controlled, accessed, or operated. Control code sets for remote video devices are mapped to a local interface control set. Local input is translated to a remote video device command based on such mappings.

  • Patent number: 8544034
    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 allow users to provide input to an ETMP studio application for generating remote control commands to send to a desired multimedia handling device (MHD) representing an emulated MCDN client. The user input may be captured to generate an ETMP script, which may be stored in a globally addressable format that is reusable with other MHDs in the ETMP. Additional functionality for editing and combining portions of ETMP scripts to generate further ETMP scripts may also be provided.

  • Patent number: 8352994
    Abstract: 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.

  • Patent number: 8332900
    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.

  • Publication number: 20120143359
    Abstract: A particular method includes receiving, at a control server from a user terminal, input selecting at least one media device that generates media output in an output format. The method includes sending a signal from the control server to a media switch to couple an output of the at least one media device to the user terminal. The media output of the at least one media device is sent to the user terminal in the output format when the output is coupled to the user terminal. The method includes receiving, at the control server from the user terminal, a command to be performed by the at least one media device. The method also includes sending command data from the control server to one or more controllers associated with the at least one media device. The at least one media device is controlled based on the command data to perform the command.

  • Publication number: 20120143606
    Abstract: A method and system for monitoring video assets provided by a multimedia content distribution network includes testing closed captions provided in output video signals. A video and audio portion of a video signal are acquired during a time period that a closed caption occurs. A first text string is extracted from a text portion of a video image, while a second text string is extracted from speech content in the audio portion. A degree of matching between the strings is evaluated based on a threshold to determine when a caption error occurs. Various operations may be performed when the caption error occurs, including logging caption error data and sending notifications of the caption error.

    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 allow execution of ETMP scripts that specify remote control commands to send to a desired plurality of multimedia handling devices representing emulated MCDN clients. The ETMP scripts may be manually or automatically initiated and may be configured with execution parameters specifying, among other aspects, a number of iterations to repeat. Results recorded when the ETMP script executes may be retrieved and used to generate reports.

  • Publication number: 20120066735
    Abstract: A method and system for performance monitoring of a multimedia content distribution network (MCDN) includes a probe device configured to capture input and output data with respect to a network terminal device at an MCDN client premises. The input data, representing network data sent to the MCDN client for display, may be buffered along with the output data, representing audio and video data generated using the input data. When an anomaly event, such as a display error, occurs, the probe device may record the buffered input and output data, including data acquired prior to the anomaly event. The input and output data may be analyzed to determine a source or origin of the anomaly event. The probe device may also certify that the MCDN and/or the network terminal device was operating normally.

  • Publication number: 20110090346
    Abstract: Remote video devices are monitored by receiving video pattern data from the remote video devices and comparing device video patterns represented by the video pattern data to predetermined video patterns. If device video patterns match the predetermined video patterns, a rule corresponding to the predetermined video pattern is accessed and execution of a recovery action is initiated.
