Abstract: A method is disclosed of analyzing a video stream using a video analyzer. The video stream includes image frame data corresponding to an integer N number of image frames, respectively. The video analyzer includes a controller and a frame processor. The method includes setting a problem threshold value corresponding to a parameter of the image frame data, receiving first image frame data corresponding to a first image frame, analyzing the parameter of a portion of the received first image frame data and generating an analyzed value and determining whether there is a problem based on the analyzed value and the problem threshold value. The portion of the analyzed portion of the received first image frame data is less than the total received first image frame data.

Abstract: The present provides a resource allocation system, including providing a workstation session manager in a workstation, coupling a resource schedule manager to the workstation session manager, coupling a disk drive storage system to the resource schedule manager, and provisioning a workflow process on the desk drive storage system utilizing the resource schedule manager.

Abstract: Apparatus and methods for efficient queuing and dequeuing using segmented output buffers comprising sub-buffers and priority queues. Output buffers are monitored for empty sub-buffers. When a newly empty sub-buffer is discovered, a refill request is enqueued in a ranked priority queue wherein the rank of the destination priority queue is based on the number of empty-sub-buffers in the requesting output buffer. All high priority refill requests are dequeued before lower priority refill requests, thereby reducing the possibility of starvation. Optionally, by using simple dequeuing criteria, such as a FIFO discipline, instead of complex algorithms designed to improve fairness, system resources may be conserved thereby improving system throughput.

Abstract: The invention described herein improves and expedites compressed video data delivery by providing systems and methods for transcoding and pass through on a sub-picture level. For example, in MPEG embodiments described herein, transcoding and compressed video data pass through may occur on a macroblock or slice level. This permits portions of a picture that need no rate reduction to be passed through without transcoding. The invention may also implement pass through on a picture by picture basis. Accordingly, the invention may determine transcoding or pass through for each picture or picture subregion. Thus, systems and methods described herein provide flexible compressed video data transcoding and pass through, as determined by varying bit rate demands of compressed video data transmission.
