Presented herein are system(s), method(s), and apparatus for determining the presentation time for a picture without a presentation time stamp. A first and second picture are decoded. The first picture is a reference picture for the second picture. The presentation time for the second pictures is computed as a function of a presentation time and a decode time for the first picture.

System, method, and apparatus for determining presentation time for picture without presentation time stamp

Disclosed are various embodiments that facilitate recording to a storage medium in a personal video recorder (PVR) system. In one embodiment, a transport stream is received. The transport stream is stored into a memory. An index table is generated that provides information for locating particular frames recorded in the memory.

Method of timebase management for MPEG decoding with personal video recording functionality

A system, method, and apparatus for playback of multiple video elementary streams is presented herein. A host processor modifies the video elementary streams to allow a transport demultiplexer to distinguish among the plurality of the video elementary streams.

System, method, and apparatus for playing back a plurality of video elementary streams with one playback channel

Command packets for a personal video recorder that provides for a transport stream (TS) that contains data and also includes a transport packet (TP)/TS formatted command packets. The TP/TS formatted command packet may be communicated between any number of devices, including multiple chips, multiple boards, and multiple processors. A decoder is able to decode the TP/TS formatted command packet and to perform the appropriate operation on data portions of the TS. When a TS is provided to a device not having the capability to perform the proper decoding of the TP/TS formatted command packet, that particular packet may be deemed as being unidentified (or unknown) adaptation field data. Alternatively, the packet may be identified as being corrupted data and/or irrelevant data.

Command packets for personal video recorder

Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. Error concealment of MPEG data may take place within various components within playback, recording, reading and writing data systems. The error concealment may be provided within existing systems whose components may not be capable of accommodating errors within MPEG data. In certain embodiments, the available data that contain no errors is maximized to conceal those portions of the data that do include errors.

Error concealment for MPEG decoding with personal video recording functionality

Presented herein are a system, method, and apparatus for audio and video synchronization. In one embodiment, there is presented a method for displaying audio data and video data. The method comprises examining a plurality of portions of the audio data, where each of said plurality of portions of audio data is associated with a time stamp; examining a plurality of portions of the video data, where each of said plurality of portions of the video data is associated with a time stamp; decoding one of the portions of the video data; and decoding one of the portions of the audio data while decoding the one of the portions of the video data. The difference between the time stamp associated with the one of the portions of the video data and the time stamp associated with the one of the portions of the audio data is within a certain margin of error from a predetermined offset.

Displaying audio data and video data

Described herein is a system and method for audio visual synchronization. The picture are displayed by receiving an identifier, said identifier associated with a frame buffer storing a picture; extracting a presentation time stamp associated with the picture, wherein the picture is associated with a time stamp; comparing a local time clock value to the presentation time stamp; determining that the picture is mature for presentation if the presentation time stamp exceeds the local time clock value by less than a first predetermined threshold; and determining that the picture is mature for presentation if the local time clock value exceeds the presentation time stamp by less than a second predetermined threshold.

System and method for audio/video synchronization

Presented herein are systems, methods, and apparatus for improving performance of video decoders during rewind and fast forward operation. Video decoder performance is improved by avoiding repetitive decoding of prediction pictures. When a decoded prediction picture is stored in a frame buffer, techniques are presented for decoding multiple pictures in the rewind order which are dependent thereon, displaying the picture directly from the frame buffer, and setting one type of prediction picture as another type of prediction picture.

Performing personal video recording (PVR) functions on digital video streams

A television on a chip (TVOC) system that provides a cost effective approach for providing television functionality on a single integrated circuit chip is disclosed. A TVOC includes the functionality necessary to receive and display television signals in a variety of input and output formats. A TVOC can be used in set-top boxes for cable and satellite television, or directly within a television. All functionality provided can be provided on a single integrated circuit. TVOC includes a data transport module, an IF demodulator, a digital audio engine, an analog audio engine, a digital video engine, and an analog video engine. The TVOC also includes three sets of interfaces including output interfaces, control interfaces and ancillary interfaces. Further features and embodiments provide enhanced functionality and increased efficiencies.

Television functionality on a chip

Systems and methods that provide time-based management for MPEG decoding are provided. In one example, a method for live decoding in a personal video recorder system includes the steps of receiving at least one data packet; determining at least one program clock reference (PCR) using the at least one data packet; and locking a timing mechanism to the at least one determined PCR.

Presented herein is a system and method for reducing the total size of the frame buffer portion of a decoding circuit. The reduction in size is possible because first portions of B-pictures are displayed while second portions occurring later in the raster order are decoded. The foregoing allows the second portions occurring later in the raster order to overwrite third portions of the picture that have already been displayed. As a result, the frame buffer for providing the frame from a decoder to the display engine need only store the portion that is being displayed and the portion that is being decoded.

Delta frame buffers

Systems and method for processing v-chip data for an MPEG-2 decoder with personal video recording functionality are provided. In one example, a system that processes V-Chip data with personal video recording functionality may include a data transport engine and a video decoder. The video decoder may be coupled to the data transport engine and may be adapted to parse out V-Chip data.

V-chip data processing for decoder with personal video recording functionality

Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. Error concealment of MPEG data may take place within various components within playback, recording, reading and writing data systems. The error concealment may be provided within existing systems whose components may not be capable of accommodating errors within MPEG data. In certain embodiments, the available data that contain no errors is maximized to conceal those portions of the data that do include errors. Various layers may be accommodated while performing error concealment, including the MPEG transport stream layer, the video layer, and the audio layer.
