A method and apparatus for synchronizing streaming media with multiple output devices. One or more media servers serve media streams to one or more output devices (i.e., players). For playback synchronization, one output device is the “master”, whereas the remaining output devices are “slaves”. More data is requested from the media server by the “master” device to maintain a nominal buffer fill level over time. The “slave” devices receive streamed data from the media server at the rate determined by the master device's data requests, and the average rate of data flow over the streaming network is thus controlled by the frequency of the single “master” device's crystal. “Slave” devices make playback rate corrections to maintain respective buffer fill levels within upper and lower threshold levels. For slow networks, each media data packet timestamp is calculated from the time the master's buffer reaches nominal level.

An audio encoder applies an adaptive block-encoding process to segments of audio information to generate frames of encoded information that are aligned with a reference signal conveying the alignment of a sequence of video information frames. The audio information is analyzed to determine various characteristics of the audio signal such as the occurrence and location of a transient, and a control signal is generated that causes the adaptive block-encoding process to encode segments of varying length. A complementary decoder applies an adaptive block-decoding process to recover the segments of audio information from the frames of encoded information. In embodiments that apply time-domain aliasing cancellation (TDAC) transforms, window functions and transforms are applied according to one of a plurality of segment patterns that define window functions and transform parameters for each segment in a sequence of segments. The segments in each frame of a sequence of overlapping frames may be recovered without aliasing artifacts independently from the recovery of segments in other frames. Window functions are adapted to provide preferred frequency-domain responses and time-domain gain profiles.

A multimedia server system includes a disk array subsystem including a plurality of multimedia files, e.g., movies, a media file system manager for managing the storage of the plurality of multimedia files within the disk array subsystem, and a playlist which includes a list of titles of specific multimedia files to be played at designated times. The multimedia server system advantageously includes synchronization parameters associated with each of titles specified by the playlist. The synchronization parameters are programmed to specify the manner in which particular files should be truncated in order to compensate for admission delays. An admission delay synchronization unit receives the synchronization parameters and truncates the multimedia files as specified by the synchronization parameters. In one implementation, a first synchronization parameter is used to specify that the current file should be truncated at the time for the play of the next file. A second synchronization parameter specifies that up to a given amount of time should be sacrificed at the beginning of the next file to account for the admission delay of the current file. In this manner, the beginning of the next file is truncated. Still a third synchronization parameter is provided to specify an amount of time up to which the current file will be truncated at it's end to account for it's admission delay. As a result, the truncated file can be played in a shorter amount of time than the scheduled duration, and the "excess time" created is available to absorb any admission delay.

FIG. 7 shows a camera system (700) that operates to time-stamp video content captured from multiple cameras (740) relative to a recorded and time-synchronized location of a portable tracking unit (722). The position of the cameras (740) is known to the system. Based on the time and position data for each uniquely identifiable tracking unit, an editing suite (770) automatically compiles a composite video made up from time-spliced video segments from the various cameras. Video or still images captured by the cameras (740)are cross-referenced against the client address stored in database (760) and related to the assigned, uniquely identifiable tracking unit (722). A server (750) is arranged to use the client address to send reminder messages, which reminder messages may include selected images taken by the composite video. Alternatively, a client (720) can use the client address to access the database and view the composite video. In the event that the client (720) wants to receive a fair copy of the composite video, the server (750) is arranged to process the request and send the composite video to the client. Streaming of multiple video feeds from different cameras that each encode synchronized time allows cross-referencing of stored client-specific data and, ultimately, the assembly of the resultant composite video that reflects a timely succession of events having direct relevant to the client (720).

Events in a first data stream are correlated with events in a second data stream based on a method of indexing. As information of a first and second data stream are stored to a data file, the data streams are monitored for certain trigger events. An informational data set is generated and stored in an index file for each detected trigger event. Preferably, each informational data set includes the type of detected event, a time-stamp indicating when the event occurred and a data pointer indicating where the data associated with the event is stored in a corresponding data file. When time-stamps of detected trigger events in both data streams are generated based on a common system clock, data in one data stream is correlated with data in another data stream based on the time-stamps.

An audio/video (A/V) hub that coordinates playback of audio content is described. In particular, the A/V hub may calculate current time offsets between clocks in electronic devices and a clock in the A/V hub based on differences between receive times when frames are received from electronic devices and expected transmit times of the frames. For example, the expected transmit times may be based on coordination of clocks in the electronic devices and a clock in the A/V hub at a previous time and a predefined transmit schedule of the frames. Then, the A/V hub may transmit, to the electronic devices, one or more frames that include audio content and playback timing information, which may specify playback times when the electronic devices are to playback the audio content based on the current time offsets.

In performing stereoscopic view, a shift information memory (21) stores, as a number of pixel lengths, an offset indicating how far in a right direction or a left direction to move coordinates of pixels to realize stereoscopic view. When realizing stereoscopic view, a plane shift engine (20) moves the coordinates of image data in a graphics plane in the right direction or the left direction by the number of pixel lengths indicated by the offset. When a scale of video data targeted for stereoscopic view is changed by a basic graphics plane (15), a shift distance of pixel coordinates by the plane shift engine (20) is based on a number of pixel lengths obtained by multiplying the offset by a changed scaling factor in the horizontal direction.
