摘要： The exemplary embodiments of this invention provide in one aspect thereof an ability to signal multiple decoding times for each sample in a file format level in order to allow, for example, different decoding times for each sample (or sample subset) between decoding an entire stream and decoding a subset of the stream. An alternate decoding time box is specified to allow for the signaling of multiple decoding times for each sample. Such a box can contain a compact version of a table that allows indexing from an alternate decoding time to a sample number, where an alternate decoding time is a decoding time to be used with a sample when only a subset of an elementary stream stored in a track is to be decoded. Furthermore, each entry in the table provides the number of consecutive samples with the same time delta, and the delta between those consecutive samples. By adding the deltas a complete time-to-sample map can be constructed.

摘要： Methods and systems for coordinating user terminals are disclosed. A user terminal may receive a user terminal identifier and a sensor identifier from a user terminal, determine a group topology based on the user terminal identifier and the sensor identifier to identify a spatial relationship relative to the user terminal, receive a media signal, and identify a subsection of the media signal. The user terminal also may generate subsection information to assign a subsection of the media signal to the user terminal corresponding to the spatial relationship, and may communicate the subsection information to the user terminal.

摘要： A system and method for conveying information that is helpful for a network middlebox or a media player to decided which coded data units to forward or process within an RTP payload or a file format data unit in an easy-to-access manner. This mechanism can be used to provide indications of items such as redundant coded pictures, temporal level switching points, gradual decoding refresh access points, view identifiers, and view random access points. A middlebox and/or receiver can then use this information to determine whether certain coded data units need to be processed and/or transmitted.
