摘要： A stream of signal values is adaptively encoded using a predetermined set of code words with diverse codeword lengths. A running histogram of estimated frequencies of occurrence of respective ones of the signal values is maintained. The assignment of code words to signal values is changed between one signal value and the next. The different assignment is determined by selecting a permutation of the assignment of codeword to signal values. A permutation is selected that has a decreased a sum of the codeword lengths weighted by the estimated frequencies of the signal values to which the code words are assigned, compared to a current assignment. During decoding of the outputted code words the same permutations are made.

摘要： A decompression process is used that forms a decompressed data value by adding a correction value to a signal value prediction. During compression the required correction value is computed. The correction value is encoded in two parts, such as an absolute value and a sign. It is tested whether more than one valid possible decompressed data value can be obtained by adding the signal value prediction to all of a plurality of different possible correction values that are consistent with a first part. A second part of the correction information is included in the compressed data, for selecting among the more than one possible decompressed data values, conditional on a result of said testing. The second part is omitted in cases where there is no more than one valid possible decompressed data value. During decompression the prediction is determined and it is tested whether the second part is needed or not to determine an unambiguous signal value. The second part is read from the compressed data when it is needed to select an unambiguous signal value.

摘要： Data, such as an image, is made up of data-items (pixels) that are each associated with a respective data address. Compressed blocks representing the data are stored in a memory system. Each block representing compressed data-items associated with data addresses in a respective sub-range of addresses of the data. Each block starts from a respective preferred starting address for multi address transfer. The sub-range of addresses of each block has a length corresponding to an address distance between the preferred starting address, leaving memory addresses not occupied by the particular block in between blocks due to compression. A decompressor is coupled between a processing element and the memory system. The decompressor starts a multi address memory transfer of a required one of the blocks from the memory system dynamically when the processing element requires access to the block, leaving memory addresses directly following the block up to a preferred starting address for a next one of the blocks untransferred in the transfer. The transferred data is decompressed and passed to the processor.

摘要： Bit-rate scalable compression for storing A/V information in a pause buffer of a digital video recorder, providing a viewer of a live program to take a delayed decision about whether or not to record the program while still viewing the "live" program at full quality, i.e. at a higher quality than the quality at which it will be stored, whereby only the "enhancement layers" need to be stored in the buffer, whereby since the bit rate of these layers is significantly lower than the bit rate for the complete compressed data, the capacity (minutes of recording time) of the buffer is significantly increased.

摘要： In a method of selecting a teletext page, a user enters at least a first digit in a desired teletext page number, and a table (33) comprising combinations of a page number and an indication of the probability of the corresponding page being desired is consulted. The table (33) is a histogram of previously selected pages. A complete teletext page number is selected from the table (33) on the basis of the probability indications after part of the desired teletext page number has been entered, and may depend on the currently displayed page. The likelihood information can also be used in page selection with a 'zap' button. When this button is pressed, the next most likely page is displayed.

摘要： A hither before unknown cause of image artefacts has been identified. Encoders such as MPEG encoders may use two picture structures: Field pictures and frame pictures. For a frame picture both frame and field-based DCT (and other types) of coding may be used. The decision whether to use frame or field based coding is not always made correctly. In the decoded image this leads to an image artefact visible as stripped blocks. The invention reduces, in one aspect of the invention, these artefacts by analyzing the block content on the presence of such artefacts and if the analysis proof the existence of such artefacts applying a vertical low pass filter to the data in the block. In another aspect of the invention encoding parameters are checked for combination of encoding parameters for which the artefact may occur and such blocks are indicated. The invention may be embodied in a method as well as in a device such as a receiver, encoder, decoder, display device etc.
摘要翻译：在未知的图像伪像原因之前已被确定。诸如MPEG编码器的编码器可以使用两个图像结构：场图像和帧图像。对于帧画面，可以使用基于帧和场的DCT（和其他类型）的编码。决定是否使用基于帧或场的编码并不总是正确的。在解码图像中，这导致图像伪像作为剥离块可见。在本发明的一个方面，本发明通过在存在这种伪影的情况下分析块内容来减少这些伪像，并且如果分析证明这样的伪像的存在对块中的数据应用垂直低通滤波器。在本发明的另一方面，检查编码参数的组合，其中可能发生伪影的编码参数和指示这些块。本发明可以以一种方法以及诸如接收机，编码器，解码器，显示装置等的装置来体现。

摘要： In a method for coding and decoding indicator data (d(x, y), S)are compared to a criterion (T). If the indicator data meet the criterion, an absolute value (Hival/Loval) is inserted instead of a predicted value based on differential coding. This amounts to a bypass of the differential coding loop, which reduces or eliminates oscillatory behavior in such loop, thereby reducing smearing of text parts of a compound image. The absolute values are preferably dynamically determined on the basis of previous predicted values.
摘要翻译：在将指示符数据（d（x，y），S）进行编码和解码的方法与标准（T）进行比较。如果指示符数据满足标准，则插入绝对值（Hival / Loval），而不是基于差分编码的预测值。这相当于差分编码环路的旁路，这减少或消除了这种环路中的振荡行为，从而减少了复合图像的文本部分的拖尾。绝对值优选基于先前的预测值动态地确定。
