摘要： First digital audio-visual program video component(s) are switched on a second digital audio-visual program video component(s) by switching on the beginning of the first set of images including an Intra-coded picture of the second program video component encountered after the switching command. In the transmission order of images, each bidirectionally predictive-coded picture of the first set of images referring to the set of images pertaining to the set of images preceding it before switching, is substituted for a bidirectionally predictive-coded picture of the video coding which is produced independently of (1) the substituted image content and (2) the contents of the images to which it refers.

摘要： For some video processing applications, most notably watermark detection (40), it is necessary to add or average (parts of) the two interlaced fields which make up a frame. This operation is not trivial in the MPEG domain due to the existence of frame-encoded DCT blocks. The invention provides a method and arrangement for adding the fields without requiring a frame memory or an on-the-fly inverse DCT. To this end, the mathematically required operations of inverse vertical DCT (321) and addition (322) are combined with a basis transform (323). The basis transform is chosen to be such that the combined operation is physically replaced by multiplication with a sparse matrix (32). Said sparse matrix multiplication can easily be executed on-the-fly. The inverse basis transform (35) is postponed until after the desired addition (33, 34) has been completed.

摘要： An encoder is arranged to add a binary code bit to block of a signal by selecting, within the block, (i) a reference frequency within the predetermined signal bandwidth, (ii) a first code frequency having a first predetermined offset from the reference frequency, and (iii) a second code frequency having a second predetermined offset from the reference frequency. The spectral amplitude of the signal at the first code frequency is increased so as to render the spectral amplitude at the first code frequency a maximum in its neighborhood of frequencies and is decreased at the second code frequency so as to render the spectral amplitude at the second code frequency a minimum in its neighborhood of frequencies. Alternatively, the portion of the signal at one of the first and second code frequencies whose spectral amplitude is smaller may be designated as a modifiable signal component such that, in order to indicate the binary bit, the phase of the modifiable signal component is changed so that this phase differs within a predetermined amount from the phase of the reference signal component. As a still further alternative, the spectral amplitude of the first code frequency may be swapped with a spectral amplitude of a frequency having a maximum amplitude in the first neighborhood of frequencies and the spectral amplitude of the second code frequency may be swapped with a spectral amplitude of a frequency having a minimum amplitude in the second neighborhood of frequencies. A decoder may be arranged to decode the binary bit.

摘要： A method of transmitting signals along a communication path, by a first compression/decompression unit, which method comprises receiving first signals from a first direction along the path, determining based on the received first signals whether a second decompression unit is located along the path in the first direction, receiving second signals from a second direction. In the case it is determined that a second decompression unit is located along the path in the first direction, selecting a compressed or decompressed format for transmission of the second signals responsive to at least one additional parameter, such that the determination that a second decompression unit is located along the path in the first direction does not always bring about selecting the compressed format. Then, the second signals are transmitted in the selected format.

摘要： A method for pipelining variable length decode and inverse quantization operations in a hybrid motion-compensated and transform coded video decoder includes the step of mapping a new code word to a look-up table to retrieve a code word length, a zero-run length, and a quantized level. A new linear, zig-zagged position of a current coefficient is identified from the zero-run length and a previous zero-run length. The code word length is added to a current bitstream position to yield a new bitstream position. A quantization matrix coefficient from the new linear, zig-zagged position of the current coefficient is selected. The quantized level is multiplied by a predetermined value to produce a quantization product. In the case of inter block processing, a quantized level sign value is added to the quantization product. In the case of intra block processing, the quantization product does not include the quantization level sign. The quantization product is multiplied by a quantization matrix coefficient to form a derived quantization value. The derived quantization value is divided by a predetermined word length to produce a final quantization value. The new linear, zig-zagged position of the current coefficient is converted to a two-dimensional display position. The final quantization value is written at the display position.

摘要： Embodiments of the invention comprise a new device and method to realize an improved video frame memory reduction for a video decoder. In one embodiment, this improvement is achieved by a removal of the rate controller and the utilization of both a block compression technique and a fixed storage allocation technique, in order to lower the overall system cost, and to lower the frame memory requirements. In a preferred embodiment, this improvement is achieved by performing a hierarchical transform, for example, a Haar transform, that operates on the previously decoded frames. Then, the coefficients obtained from this transformation are quantized and then run-length coded, utilizing variable-length codes. The hierarchical transform preferably operates on an N×N block size with L levels of hierarchical decomposition, where N and L can be selected in advance. For example, in one preferred embodiment, N may equal 8, and L may equal 3. The compression system then fits the N×N block into an allocated storage of (N×N)/cf bytes, where cf designates the compression factor. For example, a nominal value of cf that equals 2, 3, or 4 may be utilized. The quantization process comprises a simple scaling of the coefficients. However, the DC coefficient is not scaled. The variable-length encoder comprises a run-length encoder that fits as many coefficients as is possible into the available space of the (N×N)/cf bytes.

摘要： A device for regulating bit rate in a system for statistically multiplexing several streams of MPEG 2 coded images is disclosed. The statistical multiplexing system includes a device (1) for allocating bit rate using the complexity calculated by a bit rate regulating device (10). Each coder E(i) of an image stream includes a first coding device (20) for performing spatial coding, a second coding device and a memory for storing the complexity X1st| of the last image coded spatially by the first coding device. The complexity (X−GOP) of the last group of pictures is coded by the second coding device (30). Device (10) regulates the bit rate of coder E(i) for determining the complexity value for the next image coded by the second coding device (30), using stored complexity values. This complexity value is transmitted to the bit rate allocator (1) to determine the next bit rate sent to the coder E(i).
