Abstract: A technique for detecting an encoder functionality issue in a media distribution system is presented. In the media distribution system consecutive media segments generated by an encoder are transmitted to a media client, and media descriptions describe expected availability times of media segments for the media client. A method implementation of the technique comprises the step of monitoring an availability time of a media segment compared to an expected availability time of the media segment, wherein the expected availability time is described by, or derived from, a media description. The method further comprises determining whether a deviation of the monitored availability time of the media segment from the expected availability time of the media segment is present, and detecting the encoder functionality issue based on a result of the determination. The encoder functionality issue may comprise one or more of an encoder restart, an encoder malfunction and an encoder time drift.

Abstract: Methods, devices, systems, and non-transitory process-readable storage media for scalable data service distribution in WiFi Miracast. A processor of a source computing device in a WiFi Miracast network may group all sink computing devices scheduled to receive a frame or packet of a service into a single multicast group and transmit a multicast frame or packet to the sink computing devices. Individual sink computing devices in a WiFi Miracast network may be configured to send error logs indicating the quality of their respective wireless connections with a source computing device to the source computing device. A source computing device may add multicast group member sink computing devices to a unicast group based at least in part on missing and/or received error logs from the multicast group member sink computing devices.

Abstract: A user equipment node, upon determining that the data loss in a requested file is above, or likely to be above a threshold value, transmits a delivery missing report to a server node indicating that the data loss in the requested file is above the threshold value. The delivery missing report is used by the server node for determining whether or not a multicast file repair procedure should be enabled, based on the number of delivery missing reports it has received from other user equipment nodes. This enables a point-to-multipoint file repair procedure to be enabled sooner, and prevent a flood of point-to-point file repairs.

Abstract: A network element (100) comprises a memory (1004) storing a data structure arrangement. The data structure arrangement includes: an ordered list of asset blocks (CHVq_1, ... CHVq_N) having a head end and a tail end, each of the asset blocks indicating a number of clients (102, 104, 106, 108, 110, 112) in an access network (AN1, AN2, AN3) currently streaming video content of a corresponding channel, the asset blocks being ordered according to the number of clients currently streaming the video content for each channel; and a border structure block (208) storing a pointer to a border asset block within the ordered list of asset blocks, the pointer to the border asset block defining an active set of multicast channels for the access network, and causing the multicast controller to direct a termination node to provide the active set of multicast channels to the clients in the access network.

Abstract: Systems and methods are described herein for detecting information that indicates that a user will be traveling from a first geographic location to a second geographic location, and responsively accessing a playlist indicated by a profile of the user that indicates a plurality of streaming media that the user intends to consume. Control circuitry may then compare data corresponding to each streaming media of the plurality of streaming media to a database to determine whether each streaming media of the plurality of streaming media is accessible to the user at the second geographic location, and may determine that a subset of the plurality of media is not accessible to the user at the second geographic location. In response to determining that the subset is not accessible to the user at the second geographic location, the control circuitry may download each media of the subset.

Abstract: In an embodiment, a transmitting device transmits a real-time media stream for a real-time communication session to a set of target devices. At least one of the set of target devices detects a media reception gap in the real-time communication session, and transmits a rewind request to the transmitting device to trigger the transmitting device to generate and provide a time-delayed version of the real-time media stream that includes media lost during the media reception gap. The transmitting device generates a rewind stream based on the rewind request and transmits the rewind stream to the at least one target device.

Abstract: A first UE receives a request for a service from an application running on a second UE or an application running on the first UE. The second UE is different than the first UE. The request for the service is a request for a set of files/streams through an MBMS service. The first UE attempts to receive the set of files/streams through the MBMS service from one of a base station or a third UE. The first UE sends a reception report including at least one of a reception acknowledgement or a statistical report associated with the set of files/streams. The at least one of the reception acknowledgement or the statistical report associated with the set of files/streams includes an identifier associated with at least one of the second UE, the third UE, the application running on the second UE, or the application running on the first UE.

Abstract: The disclosure discloses a method and system for implementing a broadcast group call in a click to dial service, which is used to resolve technical problems with the conventional CTD service which cannot implement the group call of multiple logical callees and does not support functions such as broadcasting. In the disclosure, the signaling control and conference mixing are performed by a click to dial service application server and no specific terminal is required, and the group call and broadcasting of multiple logical callees can be implemented under the control of the click to dial service application server, every logical called user can access the call as long as he/she goes off-hook. The disclosure extends the functions of the existing click to dial service, extends the application of the click to dial service, and satisfies multiple demands of users.
