Abstract: Apparatus, methods, and computer program products are provided for receiving and presenting, or playing-out, representations of media content and for enabling time synchronization and random seeking across multiple representations. A client device can access an appropriate time mapping fragment that associates play-out time intervals of the media content of the multiple representations with the corresponding media segments to identify the appropriate media segment corresponding to the desired time point within the current representation or in another selected representation. The time mapping fragments may be created and preloaded onto a media content server, and the media content server may transmit the time mapping fragment(s) to a client device upon receiving a request form the client device or as part of a media segment. In other cases, the media content server may create the time mapping fragments dynamically, e.g., upon receiving a request from the client device.

Abstract: 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.

Abstract: Systems and methods of signaling changes and updates associated with the default notification channels in a non-time sliced way are provided. A default notification channel event is signaled to a terminal. The signaling includes a reference to the relevant default notification channel, a timestamp, and/or a version number/counter. A comparison is made between a stored timestamp and/or version number/counter with the timestamp and/or version number/counter indicated in the signaling. A more recent timestamp and/or version number/counter prompts the terminal to tune in to the default notification channel to process the default notification channel event. The signaling can be performed using Program Specific Information/Service Information (PSI/SI), which is non-time-sliced and is received by all terminals. Additionally, the PSI/SI signaling is effectuated by creating descriptors in existing notification/network information tables and/or by creating a dedicated notification signaling table.

Abstract: A system and method for providing MBMS content distribution using unicast bearers. According to various embodiments, MBMS download user services are delivered to pieces of user equipment by delivering a FLUTE file delivery table via an OMA Push message. One of a number of different additional actions may be used in the delivery of the MBMS download user services. These actions include (1) making a single HTTP GET request using simple URL-encoding format to retrieve all files of the FDT; (2) making a single HTTP GET request using "group" field of FDT in URL- encoding to retrieve a logical group of files of the FDT; (3) making pipelined HTTP GET requests where each HTTP GET request retrieves at least one file of the FDT; (4) making serialized HTTP GET requests where each HTTP GET request retrieves at least one file of the FDT; (5) making pipelined HTTP GET requests where each HTTP GET request retrieves at least one logical group of files of the FDT; (6) making serialized HTTP GET requests where each HTTP GET request retrieves al least one logical group of files of the FDT; (7) delivering the servicelD of the MBMS user service in the above mentioned OMA PUSH message but not including the servicelD in the FLUTE FDT; (8) an HTTP request to de-register the MBMS UE from the BM- SC for stopping the unicast delivery of the MBMS download user service; and (9) delivering the FDT Instance ID of the FDT Instance in an OMA Push message,

Abstract: A system and method are provided for changing the file repair functionality associated with MBMS systems in order to allow for the unambiguous identification of a file version in the file repair request. A file repair request is extended by information that can globally, and independently of the file download session, identify the version of a file. According to one embodiment of the present invention, a last modification date of a file can be utilized in conjunction with the file's URL to identify the file and its version. According to another embodiment of the present invention, a hash value of the file can be utilized in conjunction with the file's URL to identify the file and its version.
