摘要:
A system and method for decoding a digital video data stream. In one aspect, a plurality of hardware acceleration modules are used together with a core processor. The accelerators operate in a decoding pipeline wherein, in any given stage, each accelerator operates on a particular macroblock of video data. In the subsequent pipeline stage, each accelerator works on the next macroblock in the data stream, which was worked on by another one of the accelerators in the previous stage. The core processor polls all of the accelerators during each stage. When all accelerators finish their tasks for a given stage, the core processor initiates the next stage. In another aspect, two variable-length decoders are employed to simultaneously decode two macroblock rows of a video frame. Each variable-length decoder works to decode an assigned row and the rows are variable-length decoded in parallel. The variable-length decoders operate as part of a pipeline wherein the variable-length decoders alternate, stage-by-stage, decoding macroblocks.

Means of communicating between modules in a decoding system. A variable-length decoding accelerator communicates with a core decoder processor via a co-processor interface. In one embodiment, other decoding accelerators, in addition to the variable-length decoder, are adapted to provide status data indicative of their status to a co-processor status register. In another embodiment, a decoding accelerator is controlled by providing commands to the accelerator via posted write operations and polling the accelerator to determine whether the command has been performed. In still another embodiment, a first hardware accelerator communicates with a core decoder processor via a co-processor interface and other decoding accelerators, in addition to the first hardware accelerator, are adapted to provide status data indicative of their status to a co-processor status register.

The invention refers to mono- and divalent (diabody) single chain Fv (scFv) antibody fragments, obtained by recombinant DNA techniques from the anti-carcinoembryonic antigen (CEA) monoclonal antibody (Mab) CB/ior-CEA. 1. This antibody has high affinity for CEA and is employed in the diagnosis and follow-up of human colorectal tumors. As the original Mab, the monovalent fragment and the diabody exhibit high affinity for human CEA and recognize an epitope dependent of carbohydrate conservation. The monovalent scFv fragment and the diabody have affinity constants for CEA of (5.0±0.4)×109 L mol−1 and (2.8±0.3)×1010 L mol−1, respectively. These two fragments do not show cross reactivity with human normal cells and tissues, exception made of the normal colonic mucosa, where CEA is occasionally present. The fragments can be produced through the expression in recombinant microorganisms, starting from the cloning of the encoding variable region nucleic acid sequences obtained from the hybridoma that produces Mab CB/ior-CEA.1. As the original Mab, the monovalent scFv and the diabody have the ability to identify in vivo cells that produce human CEA and grow as tumors in mice. The monovalent scFv and the diabody have a molecular size 5 and 2.5 times lower, respectively, than the mouse Mab, and do not have Fc domains, fact this that confers them the potential to better penetrate tissues in vivo and to be less immunogenic in man.

Output buffer (100) translates input signals from one voltage range to a second voltage range. The second voltage range may be identical to the first range or may be greater. The particular range is programmable by one of several ways. This feature makes output buffer especially suitable for use in devices which must be compatible with two voltage ranges. Output buffer uses a bias generator (110) to limit the voltage across the gate oxide of its various transistors to a level which is consistent with the first voltage range.

A real-time disk system (10) stores and plays back D1 digital 10-bit 4:2:2 component video and audio signals from magnetic storage disks (12). The system (10) has a main channel subsystem (14) with an associated smooth motion option (16) and a second or key channel option subsystem (18) with an associated smooth motion option (20). Serial and parallel D1 digital video inputs (30) and (32) and outputs (34) and (36) are connected to each of the channels (14) and (18) and to control subsystem (22). In the main channel (14), the serial and parallel D1 input (30) is connected through an input board (60) to a video processing board (62). The video board (62) is connected by a bidirectional, 11.times.2 wide bus (64) to disk arrays (66) and (68). Digital video signal information is stored and retrieved in parallel to and from the disk arrays (66) and (68) without requiring any serial to parallel or parallel to serial conversion. Smooth motion option (20) processes a group of video fields by creating a plurality of additional fields between two original fields in the group of video fields by a combination of motion adaptive interpolation and frame repetition.

A method, system and device are provided for pre-filtering device for filtering a video signal prior to digitally encoding. The method includes receiving at least one input picture and at least one reconstructed picture from an encoding process and performing an in-loop temporal filtering process using at least one input picture and at least one reconstructed picture from an encoding process to output a pre-filtered video signal for use in an encoding process. The result is enabling an encoding process to produce an output with increased temporal correlation between adjacent pictures regardless of the coding type, since the artifacts introduced by the encoding process are also considered by the process.
