Abstract: Mechanisms for performing decoding of context-adaptive binary arithmetic coding (CABAC) encoded data. The mechanisms receive, in a first single instruction multiple data (SIMD) vector register of the data processing system, CABAC encoded data of a bit stream. The CABAC encoded data includes a value to be decoded and bit stream state information. The mechanisms receive, in a second SIMD vector register of the data processing system, CABAC decoder context information. The mechanisms process the value, the bit stream state information, and the CABAC decoder context information in a non-recursive manner to generate a decoded value, updated bit stream state information, and updated CABAC decoder context information. The mechanisms store, in a third SIMD vector register, a result vector that combines the decoded value, updated bit stream state information, and updated CABAC decoder context information. The mechanisms use the decoded value to generate a video output on the data processing system.

Abstract: Methods and systems are disclosed for decoding image data including I-picture, P-picture, and B-picture encoded data. A method includes receiving encoded image data and selectively performing a modified inverse discrete cosine transform (IDCT) process to generate output pixel array blocks at a lower resolution than the resolution of the received image data. The image data can be 8×8 pixel array blocks, which are used to produce lower resolution pixel array blocks such as, for example, 4×8 or 4×4 pixel array blocks. In certain instances, after the IDCT process is performed, the resulting pixel data is up-sampled before motion compensation is performed. Furthermore, in certain instances, the resulting pixel data is subjected to motion compensation and scaled to display size prior to display.

Abstract: A method for caching of stream data is accomplished by assigning for each video segment in the system a likelihood rating of future showing and then determining for each node that contains a copy of the segment a second likelihood value that reflecting a probability that the node will be used to serve streams for the segment. The future cost value of a segment copy is then predicted and preload orders are issued to nodes for segments with the per-copy likelihood above a predefined threshold.

Abstract: An EPG service architecture incorporates multiple EPG servers connected in a cluster with each EPG server having an EPG service module and a dispatcher. Each dispatcher has the capability for state determination as an active or standby dispatcher. A plurality of STBs interface with the EPG server cluster and issue requests for EPG service which are routed by the active dispatcher. The routing is accomplished by redirection of the request to an EPG service module selected from the multiple EPG servers in the cluster. Each EPG service module includes the capability for service connection to the STB upon receiving the redirection from the active dispatcher. Upon a determination that the current active dispatcher is not operating, the standby dispatchers vote for a replacement which then assumes the active dispatcher role.

Abstract: An EPG service architecture incorporates multiple EPG servers connected in a cluster. An active dispatcher is associated with at least one EPG server and multiple standby dispatchers are associated with the cluster. A plurality of STBs interfaced with the EPG server cluster issue requests for EPG service for which the active dispatcher employs an affiliation table as a portion of the cache for redirecting each request to a specific one of the EPG servers affiliated with the STB issuing the request. The active dispatcher multicasts the affiliation table to the multiple standby dispatchers for synchronization.

Abstract: A media content distribution system for distributed multimedia streaming communicates over a network and incorporates multiple independent media stations, each having a media director for control and a number of media engines for storage, retrieval and streaming of media content. A content request from a media console connected to the network is redirected by the media director to a selected one of the media engines storing content corresponding to the request for streaming. Statistical indicators are defined for measuring effectiveness of the content distribution network. Push and pull indicators with additional differentiation for remote and local access to pulled content provide means for efficiency determination of data distribution and storage. A middleware Application Programming Interface (API) structure is provided for flexible interfacing between media consoles and content distribution system components.

Abstract: A method and system for decoding symbols of variable length in a digital video bit stream in real time, using Very Long Instruction Word (VLIW) architecture. In one embodiment, several bit sections are first read from a bit stream. While the first bit section will correspond to a valid symbol in the bit-stream, the rest of the bit sections may or may not, depending on the length of the first section. A table of variable length codes is then indexed to obtain a look-up result for each of the read-in bit sections, which done in parallel for all sections. Next, a determination is made as to whether each of the look-up results is valid. A valid look-up result provides the length of the symbol. The valid look-up values are then accepted. In another embodiment the bit stream is thereafter advanced by the sum of all accepted look-up results.
