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

Described herein are system(s), method(s), and apparatus for embedding personal video recorder functions at the picture level. In one embodiment, there is presented a computer readable medium for storing a data structure. The data structure comprises a picture header and at least one command following the picture header.

Presented herein are system(s) and method(s) for clean channel changes. In one embodiment, there is presented a method for changing a channel. The method comprises receiving a portion of a first video bitstream associated with a first channel; receiving a command to switch display from the first channel to a second channel after receiving the portion of the first video; and displaying the portion of the first video bitstream associated with the first channel after receiving the command.

System, method and apparatus for clean channel change

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.

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

Described here are systems and methods for providing data starting from start codes aligned with byte boundaries in multiple byte words. A start code is written starting at a byte in a middle portion of a data word in a memory. An address associated with the byte is written in a table. Data is fetched from the memory starting from the byte.

System and method for providing data starting from start codes aligned with byte boundaries in multiple byte words

Presented herein are a system, method, and apparatus for retrieving an object from memory. The object can be stored in a manner, such that the first byte of the object and the last byte of the object are in the middle of the memory data words. The object is retrieved by a direct memory access controller. The direct memory access controller, when provided with a read transaction with the starting address and the ending address of the object, retrieves the data words storing the object, and overwrites the portions of the data word that precede and follow the object.

Direct memory accessing for fetching macroblocks

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

Presented herein is a direct memory access engine for providing data words in the reverse order. The data words are fetched in batches comprising a predetermined number of data words starting from the last data word and proceeding to the first data word. The batches are stored in a local buffer. The contents of the local buffer are transmitted in reverse order.
