摘要： PROBLEM TO BE SOLVED: To receive normal data from an arbitrary transmission data stream in a short period of time even without knowing in advance a parameter required for a receiver terminal to receive each of transmission data streams.
SOLUTION: Parameter information such as the encoding rate of convolution codes in each transmission data stream and an interleaving size is time division-multiplexed in a synchronizing signal while being spread with the same synchronization spreading code as a spreading code used for a synchronizing process of the spreading code. Therefore, as long as the synchronizing signal is being received, the parameter information is acquired regardless of the reception of each transmission data stream. Parameters for the respective parts of a receiver are set on the basis of the parameter information of transmission data streams acquired by receiving the synchronizing signal, thereby easily and speedily performing the receiving process of transmission data streams.

摘要： PURPOSE:To reduce the deterioration of resolution by cutting off an effective picture in the horizontal direction so that the aspect ratio of a high quality television system is set up to that of a standard system and matching the number of samples in the horizontal direction of the remaining picture with that of the standard system. CONSTITUTION:Since the high quality television system consisting of 1125 scanning lines is set up to 40H during a vertical blanking period, the effective scanning lines are 2X(562.5-40)=522.5X2 lines (one frame). Out of the effective scanning lines,only twice the effective scanning lines of the standard system is regarded as the scanning lines to be converted and converted into the standard system 265.2X2 scanning lines by line inserting technique. On the other hand, the effective scanning lines of the high quality television system are longer than the standard system in the horizontal direction, so that the effective pictures of the horizontal direction is cut off by about 10% on both the sides respectively so as to convert the aspect ratio from 5:3 to 4:3 and about 80% effective picture is obtained.
摘要翻译：目的：通过切断水平方向的有效图像来降低分辨率的恶化，使高质量电视系统的纵横比设置为标准系统的纵横比，并将其与水平方向的样本数相匹配剩余图片与标准系统的图片。构成：由于在垂直消隐期间由1125条扫描线组成的高品质电视机设置为40H，有效扫描线为2X（562.5-40）= 522.5X2线（一帧）。在有效的扫描线中，标准系统的有效扫描线的两倍被视为要转换的扫描线，并通过线插入技术转换为标准系统265.2X2扫描线。另一方面，高质量电视系统的有效扫描线在水平方向上比标准系统长，因此水平方向的有效图像分别在两侧被切断约10％，从而将长宽比从5：3转换为4：3，获得约80％的有效图像。

摘要： PURPOSE: To realize line soft chromakey while a separated color signal is a digital signal as it is by processing a digitized color TV signal digitally.
CONSTITUTION: The color signal C(t)(=I, Q) is separated and extracted from the color TV signal SA(t) and a difference signal generating circuit 24 obtains a chromakey signal from the difference between said signal and reference signals I' and Q'. In this case, an evaluating circuit 25 standardizes differences between I, Q, and I', Q' as shown in a figure (a) and calculates the geometric means as to deviation from a reference color to be extracted to define an evaluation function G for determining the degree of sampling. This function G is the chromakey signal. Further, a chroma signal generating circuit 27 generates a chroma signal from said color signals I and Q. A comparator 28 compares the chroma signal with a variable threshold value at a terminal 29 and a latch 30 with output control controls the chromakey signal of the circuit 25 by using the comparison result. A key signal L(t) for color removal is generated from the chromakey and color signal and a color component area is extracted to generate a key signal N(t) for screen composition from the key signal.
