Abstract: A system and method for enabling parallel decoder implementation for different views, even when there are existing dependencies between views. In various embodiments of the present invention, information is signaled to a decoder that slices are coded using certain constraints, so that parallel decoding of slices is possible. This signaling can be performed at a sequence parameter set level, or it could be performed at picture parameter set level, slice header level or macroblock header level. Additionally, the delay between various views is also signaled to the decoder, at the same location as the constraint information in various embodiments. Various algorithms can also be used to improve the coding efficiency of the system.

Abstract: A METHOD AND DEVICE FOR ENCODING, DECODING, STORAGE AND TRANSMISSION OF A SCALABLE DATA STREAM (402) TO INCLUDE LAYERS HAVING DIFFERENT CODING PROPERTIES. THE METHOD INCLUDES: PRODUCING ONE OR MORE LAYERS OF THE SCALABLE DATA STREAM (402), WHEREIN THE LAYERS ARE CHARACTERIZED BY A CODING PROPERTY, AND SIGNALING THE LAYERS WITH THE CODING PROPERTY SUCH THAT THEY ARE READABLE BY A DECODER TO DETERMINE THE CODING PROPERTY WITHOUT ANALYZING THE SCALABLE DATA STREAM (402). ALSO, A METHOD OF ENCODING, DECODING, STORAGE, AND TRANSMISSION OF A SCALABLE BIT STREAM (100), WHEREIN AT LEAST TWO SCALABILITY LAYERS ARE PRESENT AND EACH LAYER IS CHARACTERIZED BY A SET OF AT LEAST ONE PROPERTY, SUCH AS PROFILE, LEVEL AND A SET OF AT LEAST ONE HRD/VBV PARAMETER, THAT MAY BE DIFFERENT FROM THAT OF THE ENTIRE STREAM, AND WHEREIN SAID A SET OF AT LEAST ONE PROPERTY IS SIGNALED FOR AT LEAST ONE LAYER THAT IS DIFFERENT FROM THE ENTIRE STREAM, WHEREIN SIGNALING OF SAID A SET OF AT LEAST ONE PROPERTY MAY BE IN SAID SCALABLE BIT STREAM (100), IN A FILE FORMAT CONTAINER CONTAINING SAID SCALABLE BIT STREAM (100), OR IN A TRANSMISSION OR CONTROL PROTOCOL FOR TRANSMISSION OR CONTROL OF AT LEAST ONE LAYER OF SAID SCALABLE BIT STREAM (100).

Abstract: A file format design supports storage of multi-source multimedia presentation via the inclusion of indications as to whether a presentation is a multisource presentation,and for one media type,the tracks of which are from different sources and should be played simultaneously. If a multi-source presentation exists,additional indications may be provided including: an indication of a multi-source presentation type being stored; indications regarding the source of each track and which tracks have the same source; indications of different parties' information such as phone numbers, etc. Thus, a player may playback a recorded presentation in the same or substantially the same manner as it was presented during the actual session, and may automatically manipulate the presentation to be more informative or efficient. The file format design further supports storage of other types of multi-source presentations that render more than one media stream for at least one type of media.

Abstract: The invention discloses a method of improving the playback of streamed media on a client device by overcoming problems caused by variations in the transmission delay of packets due to network and transport protocol operation and variations in encoding/server specific delays. In an embodiment of the invention, a client device has a decoder (120) and a pre-decoder buffer (110) which receives streamed packets from source server via a packet network. The pre-decoder buffer is variable in size and has a variable initial buffering time for receiving the transmitted packets from the source server prior to decoding in the decoder. The initial buffering time and pre-decoder buffer size can be dynamically adapted for improved playback performance by the source server. In a further aspect of the invention, a post-decoder buffer operates in conjunction with the pre-encoder buffer to reduce decoding-related delay variations.

Abstract: A method of encoding/decoding a video sequence, which is composed of video frames. In the method, at least one video frame is divided into a set of coding blocks, and at least one of the coding blocks is encoded by intra-coding. Then a first reliable region that comprises at least one intra-coded coding block is determined, and the first reliable region in the video sequence is encoded such that creation of an information dependency between the first reliable region and coding blocks outside the first reliable region is prevented.

Abstract: The present invention relates to a method and a communication system for transmission of multimedia streams. Multimedia streams are transmitted in the communication system from a sending communication device to a receiving communication device at least partly via a wireless communication network. Information about the multimedia stream is transmitted to the receiving communication device comprising at least one parameter of the transmission of the multimedia stream for reservation of network resources. The parameter is the maximum bit rate which is needed for the transmission or the maximum service data unit size to be used in the transmission. It is also possible that both the mentioned parameters will be transmitted as attributes of the session description protocol. In an advantageous embodiment the receiving communication device informs the sending communication device about the QoS profile parameters which the wireless communication network granted for the transmission.

Abstract: Systems and methods for using sample numbers to pair timed metadata samples with media or hint samples is provided. A timed metadata sample can be paired with media or hint samples since a sample number contained in the time media sample is provided relative to the appropriate media or hint track. Additionally, an offset of sample numbers, applicable to scenarios where a plurality of timed metadata samples exist, may be added to the provided sample number to obtain the actual sample number within the media or hint track.

Abstract: Systems and methods are provided which allow receivers to recover the decoding order of network abstraction layer (NAL) units conveyed in different Real Time Protocol (RTP) sessions. An indication of decoding order for application data units (ADUs) in each packet is included in the packet structure of a PACSI NAL unit, when the PACSI NAL unit is a single-time aggregation packet type A (STAP-A) packet and the PACSI NAL unit is the first NAL unit in an aggregation packet (e.g., when a receiver is subscribed to different RTP session that convey NAL units). If the receiver is subscribed to only a base layer RTP session, the CL-DON indication can be ignored.
