摘要:
To control content distribution to plural mobile entities (20, 25-27), a device (10) for managing the distribution of the content may determine mobile entities (20, 25-27) which participate in sharing the same content and which are located in the same region. The mobile entities (20, 25-27) respectively have a first interface for communication with a mobile communication network (2, 4, 5) and a second interface for forming an ad-hoc network with another mobile entity (25-27). A message indicating at least one peer address of a peer mobile entity (25-27) may be selectively transmitted to a mobile entity (20). The peer address allows the mobile entity (20) to retrieve at least a piece of the content over the second interface from another mobile entity (25-27).
摘要:
The invention relates to techniques for providing media content in a broadcast scenario to a streaming player, like a DASH player. In order to compensate a problem of variable segment sizes, which leads to the variation in the reception intervals of the media segments, it is proposed to estimate the segment availability time for requesting subsequent media segments. The estimation considers a correction value compensating the variation in a reception intervals of media segments so that the streaming player receives the media segments at a constant time interval, namely at the segment duration. In one embodiment it is proposed to use the value of the minBufferTime from the MPD file, The minBufferTime is namely an indication of the varying segment size of the media content. The minBuFferTime indicates the time needed for buffering a media content before starting playing out said media content. The estimation may be done on the client, user equipment UE or on the server device side. If the UE is correcting the segment availability, then the UE uses the time of a first segment reception as base. If the server is correcting the segment availability then it uses the original segment availability time at the server as base plus end-to-end delay.

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.
