Abstract: Methods for monitoring quality metrics of a video session transmitted over a mobile video delivery network facility are disclosed. A method for monitoring quality of a video system that uses traffic transmitted over a mobile video delivery network facility may include tapping, by a video quality probe, into a mobile network traffic stream transmitted over the mobile video delivery network facility, filtering, by the video quality probe, the tapped mobile network traffic stream to identify an individual video session; and determining, by the video quality probe, a video quality parameter corresponding to the identified individual video session.

Abstract: Methods for monitoring quality metrics of a video session that uses traffic transmitted over a mobile video delivery network facility are disclosed. A method for monitoring quality of a video system that uses traffic transmitted over a mobile video delivery network facility may include monitoring the mobile video delivery network facility that handles at least a portion of the video traffic for the video session for information about the video traffic at a location of the mobile video delivery network facility and monitoring at least one user mobile device that plays the video delivered by the mobile video delivery network facility using a software development kit (SDK) that reports at least one media delivery quality metric.

Abstract: A method for monitoring video quality transmitted over a mobile network, comprising tapping into a mobile network traffic stream organizing the tapped network traffic into at least one individual video session associated with a single user; determining a video quality parameter for the at least one individual video session wherein the video quality parameter is at least one of packet jitter growth, packet loss, instantaneous flow rate balance (IFRB), delay between packets; a jitter statistic; a total time required to receive all packets needed to fully assemble a segment; a statistic of errors in key frames; aggregating context information for the at least one individual video session wherein context information includes at least one of cell tower, smart node, serving gateway node, user, subscriber level, device type, application, and content provider; and transmitting aggregated context information and at least one video quality parameter to a video quality server.

Abstract: A server at the edge of a broadband network distributes multimedia content streams to clients, while ensuring that the first data delivered to each client is key data (milestones) needed for correctly decoding the stream content. This is obtained by buffering the packets in the incoming stream and transmitting the packets from the buffer in an outgoing stream, starting with the most recent milestone placed in the buffer before a request to join the respective incoming stream is received. As the writing to and reading from the buffer are performed at different rates, the incoming and outgoing streams are eventually synchronized, at which point the client may be switched to receive the incoming stream directly.

Abstract: In a system that provides decoding of A/V streams, this invention reduces switching delays between different streams by modifying the Program Identification (PID) values of the Audio and Video data to respective PID values that are already known by the decoder. This technique allows the decoder to stay in a run state when switching between A/V streams, thereby reducing channel change times.

Abstract: The PIP system enables display of a mosaic of favorite channels in a Picture-in-Picture (PIP) format to a subscriber terminal. Picture-in-Picture support is efficiently provided by sending only I-Frames of the secondary video channel to the end-user. That is, any unnecessary packets (null, B-P frames, audio, etc.) in the secondary video channel are stripped away. This method uses very little bandwidth and is STB agnostic.

Abstract: Methods, devices and systems for providing content providers with a secure way to multicast their data flows only to legitimate end users. By making a specific decision for each potentially legitimate end user requesting a specific data flow, differing subscriber profiles may be taken into account. Furthermore, end to end encryption is avoided by having a switch and/or router control the specific data flow to a specific end user. Each end user sends a request DTU to the switch and/or router asking for permission to join a multicast group. The switch and/or router extracts identification data from the request data transmission unit (DTU) and determines whether the requesting end user is cleared for the requested specific data flow. This determination may be made by sending a query DTU containing the identification data to a policy server which checks the identification data against preprogrammed criteria in its databases.
