摘要： An apparatus and method for compressing multiple resolution versions of a video signal are disclosed. A first resolution version of a video signal is applied to an input of a first video compressor and to an input of a video scaler. The first video compressor encodes the first resolution version of the video signal to generate a first compressed video bit stream. The video scaler generates a reduced resolution version of the video signal from the first resolution version. The reduced resolution version is supplied to a second video compressor and to the first video compressor. The first video compressor utilizes the reduced resolution version of the video signal in performing a hierarchical motion estimation (ME) search as part of the encoding process for the first resolution version. The second video compressor encodes the reduced resolution version to generate a second compressed bit stream. The second video compressor receives motion vectors or other results of the hierarchical ME search performed in the first video compressor, and uses these results to facilitate the encoding of the reduced resolution version. The apparatus and method may be used in a non-linear video editor, a video server or other video processing system. The video scaler and first and second video compressors may share memory, a transform unit and other processing hardware such that system cost and complexity are reduced.

摘要： A process and apparatus for encoding are provided, wherein fields of a digital signal are processed to detect repeat fields. Adjacent pairs of the non-repeated fields are organized into frames. A determination is made whether to encode each of the frames as an intraframe, a predicted frame or a bidirectionally predicted frame. The frames are encoded in a specific, predefined order relative to the order of capture of the frames and the type of frame. After each bidirectionally predicted frame that immediately precedes one of the detected repeat fields, encoding of a frame is delayed for one field time. Encoding is paused after encoding each reference frame that is the very next reference frame to be encoded after a second reference frame, which second reference frame immediately precedes one of the detected repeat fields. A process and apparatus for statistically multiplexing multiple encoded digital video signals are also provided. Statistics are gathered for one or more of the encoded digital video signals and bit rates are allocated for transmitting one or more of the digital video signals as encoded. One of the digital video signals is encoded to produce a certain number of bits for each encoded picture in accordance with a decoder buffer model having a predefined size and filling at a certain bit rate, which is updated with the bit rate allocated to the one digital video signal. The update is delayed by a number of field display times depending on the number of times encoding pauses, and a presumed number of times decoding pauses, as a result of the detected repeat fields.

摘要： A system and method for receiving a video sequence with a given aspect ratio and displaying that sequence on a device with a different aspect ratio in letterbox form by performing letterbox type conversion immediately before display. In letterbox form, the viewer sees the entire active region of the picture but the whole screen is not used. In one embodiment a video sequence with a given aspect ratio can be displayed on a device with a different aspect ratio in letterbox or pan-scan form, at the users discretion, by performing, respectively, letterbox or pan-scan conversion immediately before display. Thus, the user can decide to use the entire screen or to see the entire picture.

摘要： This invention minimizes the number of non-trivial multiplications in the DCT process by rearranging the DCT process such that non-trivial multiplications are combined in a single process step. In particular, the DCT equations for the row-column application of the DCT process on k=pq points wherein p and q are relatively prime, are factored into a permutation matrix, a tensor product between matrices having p.times.p and q.times.q points, and a matrix whose product with an arbitrary vector having pq points requires pq-p-q+1 additions and/or subtractions. The tensor product is then further factored to remove non-trivial multiplications by developing a a first factor having (pq-p-q+1)/2 non-trivial multiplications and a diagonal matrix. The diagonal matrix is not unique for any set of data. Its j,j-th elements are chosen from a subproduct of the factorization of the tensor product. Once the diagonal matrix elements are chosen the remaining first factor is developed. When the factorization is complete, the diagonal matrix is absorbed into the quantization step which follows the DCT process. The quantization step is the multiplication of a diagonal matrix by the DCT output data. The quantization diagonal matrix is combined with the diagonal matrix of the DCT to form one multiplication process by which non-trivial elements multiply data. This combination of multiplication steps reduces the number of non-trivial multiplications in the DCT process.
