Abstract: 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.

Abstract: A scan technique using linear matrix to drive scan chains is used, along with an ATPG, to constraint scan test vectors to be generated through the linear matrix. The linear matrix scan technique reduces the test application time and the amount of test vector data by several orders of magnitude over conventional techniques, without reducing fault coverage.

Abstract: A system and method that support display of video fields using related data encoded in data structures. Each data structure is associated with one video field and contains all the information associated with the display of the video field. The data structure is encoded with the video field that is displayed exactly one field prior to the field associated with the data structure. In an embodiment of the present invention, the data structure contains all the information associated with the display of a video field, regardless of whether certain data changes from one field to the next.

Abstract: Presented herein is a scheme for processing multilayered packets. In one embodiment, an application engine aligns a lower level packet header with data objects in the multilayered packet. Additionally, the memory stores the objects of the multilayered packet, such that the objects start at the beginning of a data word. Remainder portions of data words can store 0's. Additionally, an object table stores records comprising object identifiers associated with particular objects, and the address where the particular object is stored.
