摘要： Decoders A and B decode MPEG-2 bitstreams A and B. A switch (S1) switches from decoded stream A to decoded stream B to achieve a splice. The resulting bitstream is re-encoded in an encoder 4. A new GOP is defined beginning at the splice. The new GOP is defined by picture type decision rules which may the effect of changing the GOP compared to the GOPs of streams A and B. The new GOP provides a prediction of the position in stream B where the occupancy value of stream C should coincide with that of B. A target for the new number of bits in the new GOP is calculated dependent on the difference between the occupancy value of stream C at the splice and a prediction of the occupancy of stream B at the predicted position. The occupancy value of stream C is controlled in accordance with the target so that it tends towards the occupancy value of stream B at the predicted position.

摘要： An image processing apparatus generating output pixel values with respect to pixels of an input image selected in accordance with an image feature direction in the input image and including a comparing mechanism comparing blocks of pixels of the input image, the blocks disposed with respect to a pixel position under test so that a correlation between the blocks would indicate an image feature direction applicable to that pixel position; and a validating mechanism detecting whether an image feature direction may be used to interpolate an output pixel value at the pixel position under test. The validating mechanism: (i) detects whether a detected image feature direction for the pixel position under test meets one or more predetermined directional criteria; and (ii) detects whether pixel values in image regions disposed with respect to the pixel position under test in accordance with possible image feature directions meet one or more predetermined pixel value criteria.

摘要： Data compression apparatus for compressing an input data unit to produce an output data unit in accordance with a desired data quantity of the output data unit, the degree of compression being determined by a compression control variable having a range of possible values. A trial encoder compresses successive sections of the input data unit in accordance with a trial group of two or more values of the compression control variable. A data quantity detector detects the trial data quantities generated by each trial encoding of the sections of the input data unit and selects a base compression control variable applicable to the input data unit on the basis of the detected trial data quantities, in order to comply with the desired data quantity. An allocator allocates a compression control variable for use in final encoding each section of the input data unit to generate the output data unit, the allocator being comparable to determine whether to use the base compression control variable or another possible value of the compression control variable for the current section.
