摘要： This invention relates to a coding system and the coding method in encoding information source symbols of an image. When the total number of original information source symbols cannot be known at the decoding site just from the encoded symbols, it is an object to finish the decoding process correctly and decode the symbols equal to the number of original information source symbols.At an encoding site, the total number of information source unit composed of a finite number of information source symbols is placed at the tail of code at the completion of encoding process. For example, at the encoding site, the number of horizontal pels of an image are transmitted in advance as an information source unit and the total number of lines are placed at the tail of code at the completion of encoding process. At the decoding site, the number of decoded lines is counted and decoded up to the number of lines placed at the tail of code. As a result, it is possible to judge the end of information source symbols without missing the total number.

摘要： A coding system comprises the comparing circuit which compares a magnitude of the range on the number line which is allocated to the most probability symbol with a magnitude of the fixed range on the number line which is allocated to the Less Probability Symbol. If the range allocated to the MPS is smaller than that to the LPS, and when the symbol is the MPS, the range allocated to the LPS is generated. If the range allocated to the MPS is smaller than that to the LPS, and when the symbol is the LPS, the range allocated to the MPS is generated. By the system, a coding efficiency is improved especially when a probability of occurrence of LPS (Less Probability Symbol) is approximate to 1/2.

摘要： A coding method of a binary Markov information source comprises the steps of providing a range on a number line from 0 to 1 which corresponds to an output symbol sequence from the information source, and performing data compression by binary expressing the position information on the number line corresponding to the output symbol sequence. The present method further includes the steps of providing a normalization number line to keep a desired calculation accuracy by expanding a range of the number line which includes a mapping range, by means of a multiple of a power of 2, when the mapping range becomes below 0.5 of the range of the number line; allocating a predetermined mapping range on the normalization number line for less probable symbols LPS proportional to its normal occurrence probability; allocating the remaining mapping range on the normalization number line for more probable symbols MPS; and reassigning the predetermined mapping range to the remaining mapping range the half of a portion where the allocated remaining range is less than 0.5, when the allocated remaining range becomes below 0.5.

摘要： Although data is transmitted with efficiency by an arithmetic encoding system, the number of carry control signals increases in proportion to the number of consecutive bits "1" s or bytes X`FF` s in a conventional system. In the present invention, an arithmetic encoder 302 `detects the possibility of a carry generated during arithmetic coding operation being propagated beyond at least a predetermined number of consecutive bytes X`FF` s in a supplied arithmetic code 315. When the propagation of the carry is impossible, a carry control signal is inserted into the first 2 bits of the byte other than X`FF` which occurs immediately after the consecutive bytes X`FF` s so as to transmit the presence or absence of a carry. An arithmetic decoder 303 detects the continuation of at least a predetermined number of bytes X`FF` s in the arithmetic code 315, and arithmetically decodes an output value YN316 on the basis of the predicted value MPS317 of the occurrence probability of the output value YN316 to be encoded and the region width Qe of the complementary predicted value LPS. Since the number of total bits of the inserted carry control signals is reduced by this "one-time 2-bits insertion system", the total number of transmitted code bits is also reduced.
摘要翻译：虽然通过算术编码系统有效地发送数据，但是进位控制信号的数量与常规系统中的连续比特数“1”或字节X'FF的比例增加。在本发明中，算术编码器302'检测在所提供的算术代码315中，算术编码操作中产生的进位在至少预定数量的连续字节X'FF之后传播的可能性。当进位传播不可能，在紧邻连续字节X'FF之后发生的X'FF'以外的字节的前2位插入进位控制信号，以发送进位的存在或不存在。算术解码器303检测算术码315中至少预定数量的字节X'FF'的继续，并且基于输出值YN316的发生概率的预测值MPS317对输出值YN316进行算术解码并且互补预测值LPS的区域宽度Qe。由于通过“一次2位插入系统”减少了插入的进位控制信号的总比特数，所以发送码位的总数也减少了。

Further, the encoding apparatus includes a boundary detector detecting a carry boundary value within the effective region at predetermined interval and instructing to truncate a part of the effective region based on the detection result.

摘要： Encoding efficiency is enhanced by actively combining a plurality of encoding methods. A picture element memory receives and stores picture elements within a predetermined range. A mode determinator selects an encoding mode based upon a reference picture element. A first encoding section and a second encoding section predicts the value of the encoded picture element, determines whether the prediction is correct, and then encodes the value of the encoding picture element based on the determination result and outputs a codeword for the encoding picture element. An encoding controller selectively operates the first encoding section and the second encoding section based upon one of the specific encoding modes and the other encoding mode other than the specific encoding mode selected by the mode determinator.
