摘要： A noise-shaping predictive coding system is disclosed, in which the deviation (i.e. correlation) of quantization representative values, which occurs when the coding noise resulting from predictive coding is frequency-shaped by a noise shaping filter, is used to perform an coding operation, so that the quantization entropy can be reduced simultaneously. According to another aspect of the present invention, the human visual characteristic may be combined with the deivation of quantization representative values.

摘要： An inter-frame adaptive prediction system for television signals is disclosed in which a prediction value P.sub.1 for a picture element 1 in the current field is newly produced, through using prediction values P.sub.OPT and P.sub.MED obtained by the following two procedures.In a first procedure, the intra-field prediction (a prediction value X.sub.N), the inter-field prediction (a prediction value X.sub.K) and the inter-frame prediction (a prediction value X.sub.F) are performed for a picture element temporally ahead of the picture element in the current field F.sub.0, for instance, the picture element 2, and a prediction circuit which yields a prediction value closer to the picture element value X.sub.2 of the picture element 2 than the prediction values of any other prediction parts is selected, and a prediction value X.sub.1S for the picture element 1 obtainable from the selected prediction circuit is obtained and is used as the prediction value P.sub.OPT.In a second procedure, the intra-field prediction, the inter-field prediction and the inter-frame prediction are carried out for the picture element 1, and prediction values obtained from the three prediction circuits are compared in magnitude with one another to obtain a prediction value corresponding to a median, which value is used as the prediction value P.sub.MED.Therefore, for a picture signal such that the moving and stationary parts are clearly distinguished in the picture, P.sub.OPT obtained by the procedure 1 provides a prediction value close to the true value. On the other hand, for a picture signal such that the moving and stationary parts are not clearly distinguished in the picture, a weighed mean value of the predicted values P.sub.OPT and P.sub.MED is employed.
摘要翻译：公开了一种用于电视信号的帧间自适应预测系统，其中通过使用通过以下两个过程获得的预测值POPT和PMED来重新产生当前场中的图像元素1的预测值P1。在第一过程中，对于在时间上在前面的图像元素执行场内预测（预测值XN），场间预测（预测值XK）和帧间预测（预测值XF）选择当前场F0中的图像元素，例如图像元素2，并且选择产生比其他预测部分的预测值更接近图像元素2的像素值X2的预测值的预测电路，以及获得从所选预测电路获得的图像元素1的预测值X1S，并将其用作预测值POPT。在第二过程中，针对像素1执行场内预测，场间预测和帧间预测，并且从三个预测电路获得的预测值的大小彼此进行比较，以获得对应于中值的预测值，该值用作预测值PMED。因此，对于图像信号，使图像中的移动和静止部分被清楚地区分，通过过程1获得的POPT提供接近真实值的预测值。另一方面，对于图像中移动和静止部分没有明确区分的图像信号，采用预测值POPT和PMED的加权平均值。

摘要： A variable length code is converted to a new code in order to improve synchronization recovery capability without changing the length of each codeword. A short codeword with high occurrence probability is first selected as a seed. An object codeword, which is longer than the seed located at a leaf of a tree structure of the code, is exchanged with another node or leaf, which at the same is located depth as that of the object codeword in the tree structure, when a rear portion, called a suffix of said object codeword, coincides with the seed. The seed is also exchanged with another node or leaf on the same level as that of the seed, and the exchange of the object codewords is effected for the fresh seed in a similar manner as above. The final seed and the object codewords are determined so that the number of the codewords which coincide with the suffixes of seeds becomes maximum.

摘要： A variable length code system which is instantaneously decodable in both forward direction and backward direction is generated either in asymmetrical form or symmetrical form. The code thus generated has high transmission efficiency, and capable of backward reconstruction of video signals even when some bits are lost during transmission. The symbols to be encoded are prepared (1) with occurrence probability, and they are provisionally encoded to a non-reversible variable length code (2). Then, the provisional code is transformed to an asymmetrical reversible code (4) through equivalent transform process (9), reverse symbol tree process (10), and bit supplement process (12) when suffix condition is not satisfied. The provisional code is also transformed to a symmetrical reversible code (3) by assigning a symmetrical code word to each symbol on a symbol tree (FIG. 5). At least one of symmetrical code or a asymmetrical code is selected (5), and is provided as a final resultant code.
