摘要： According to one embodiment, a Programmable Video Recorder (PVR) receives streaming multimedia data from a data source and stores the multimedia data in a backing store. Prior to being stored, the multimedia data is assigned Presentation TimeStamps (PTS)s according to a capture graph clock that is associated with the PVR. Thereafter, system clock times that correspond with the times in which each data packet is read from the backing store are compared with the corresponding PTSs of each data packet to generate a clock scaling value that is used to slave the system clock with the capture graph clock. The clock scaling value may include the average of a plurality of scaling values that are calculated during a predetermined duration of time corresponding with the most recently read data packets.

摘要： A computing system connected to storage medium and one or more rendering devices identifies and processes only selected frames of data that are stored on the storage medium, thereby reducing the resources and bandwidth is required to process and transmit the data to the rendering device(s) at a desired playback. The computing system has various modes for selecting the frames to be processed and transmitted. In one mode, all frames are selected. In another mode, only the key frames are selected. In yet other modes, only certain key frames are selected. Upon selecting the frames to be transmitted to the rendering device(s), the time stamps assigned to the selected frames are scaled so that the selected frames will be displayed for an appropriate duration of time that corresponds with the desired playback rate.

摘要： A programmable video recorder (PVR) includes a writer application programming interface (API) and a reader API that operate essentially independently to enable the PVR to be networked to multiple reader applications. The writer API creates a backing store and a shared memory mapped file. The backing store stores streamed data in temporary files. The shared memory mapped file stores state information of the backing store files. The reader API receives requests from reader applications to access the stored streamed data. In response to the requests, the reader API permits the reader applications to access the shared memory mapped file to determine where the stored streamed data is located. Upon locating the stored data, the reader API permits the requesting reader applications to access the stored streamed data.

摘要： A computing system connected to storage medium and one or more rendering devices receives streamed multimedia data. The multimedia data is encoded in a format, such as an Advanced Streaming Format, that is conducive to storing the multimedia data in files having appended indexes. Upon receiving the multimedia data, the multimedia data is written to file structures within the storage medium, while at the same time maintaining a real-time index for each file in a shared memory. After a file is complete, the real-time index is appended to the completed file and deleted from the shared memory. When a request for data is received that pertains to a file that does not have an appended index, the computing system obtains any necessary file index information from the real-time index in the shared memory, thereby enabling the requested data to be accessed.
