摘要： In accordance with an example embodiment of the present invention, a method and apparatus are described for assigning layers of a scalable media stream to one or more groups. A data type value is assigned to least one group, and the at least one group is mapped to a physical layer pipe. Data of the scalable media stream is transmitted in the physical layer pipe in a data frame, and a lowest data type value of groups of layers transmitted in the physical layer pipe in the data frame is signaled in the transmission of the data frame. Further, a corresponding method and apparatus are disclosed for receiving data from a scalable media stream.

摘要： An accurate indication of a re-synchronization point/time in streamed media content is provided to allow playout of the streamed media content from or at a desired point/time when a client or receiver switches from multimedia broadcast multicast service (MBMS) to packet switch stream (PSS) service. Various parameters, e.g., synchronization source (SSRC) and real-time protocol (RTP) timestamp, of a last received media RTP packet is signaled to a receiver. Alternatively, the SSRC and sequence number of the last received media RTP packet is signaled to the receiver, or the SSRC, the RTP timestamp, and the sequence number of the last received media RTP packet is signaled to the receiver. Also, a UTC clock time can be calculated based upon the last received real-time control protocol (RTCP) sender report (SR) and the timestamp of the last received media RTP packet in order to effectuate proper synchronization between MBMS and PSS servers.

摘要： Various methods are described for selecting an access method for receiving a DASH media presentation. One example method may comprise providing for reception of a media presentation description. The media presentation description may identify a first set of access methods for receiving media and may provide attribute values associated with each of the access methods. The method of this example embodiment may further comprise identifying a second set of access methods supported by an apparatus. Furthermore, the method of this example embodiment may comprise determining a third set of access methods belonging to both the first set and the second set. The method of this example embodiment may further comprise selecting an access method from the third set based at least in part on the attribute values associated with the access method. Similar and related example methods, example apparatuses, and example computer program products are also provided.
