20120066735METHOD AND SYSTEM FOR PERFORMANCE MONITORING OF NETWORK TERMINAL DEVICES - 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.03-15-2012
20130212634RECEPTION APPARATUS, RECEPTION METHOD, PROGRAM AND INFORMATION PROCESSING SYSTEM - A reception apparatus includes: a reception section adapted to receive an AV content; a trigger extraction section adapted to extract trigger information transmitted together with the AV content for rendering an application program, which is to be executed in a linked relationship with the AV content, operative; a command acquisition section adapted to acquire a command for controlling the operation of the application program in response to the extracted trigger information; and a control section adapted to control the operation of the application program in response to the acquired command.08-15-2013
