摘要： PURPOSE:To extract document information on the optional page of an accumulated optional document in a short time and to efficiently use it by accumulating document information with hierarchy structure as an independent file divided into an object unit. CONSTITUTION:Document information displayed by hierarchy structure are accumulated at the independent files 10, 20 and 21 which is divided in the object unit. Control information files 50-52 accumulate information controlling the document files, and the control information file 20 accumulates the file name (f) of the file 10 accumulating the document 1 and the directory name (d) of the files 51 and 52 accumulating information controlling the file which accumulates the contents of pages '1' and '2' that is dependent on a document 1. Consequently, objective document information can be extracted by reading directory information as retrieval information in order from a high-order to a low-order. Thus, document information on the optional page in the optional accumulated documents can be extracted in a short time and they can efficiently be used.

摘要： PURPOSE: To improve the efficiency of communication by recognizing a digital data error generated on a transmission line in each bit or frame as a pattern, judging a communication state based upon the pattern, finding out an optimum communication condition, and transmitting the condition to a transmitting side. CONSTITUTION: A communication equipment 5 receives and decodes a data signal in accordance with a communication condition set up by a system controller 6, stores the decoded signal in a communication buffer 4 built in a communication controller 1 and detects its error. A bit one-frame error pattern judging part 3 prepares data capable of judging the statistical property of an error event such as a frame error rate, a bit error rate, the dispersion of an error frame interval, and a standard deviation, finds out a communication condition such as a data rate of a current communication equipment by the use of these data and judges an optimum communication condition to be adopted next. The judging part 3 generates a control signal parameter data to be transmitted/ received to/from an opposite equipment matched with a communication protocol signal and outputs the parameter data to a sequence control part 2.

摘要： PURPOSE:To input and output different video signals simultaneously to and from one frame memory by performing input-output to and from the frame memory of second data when a transfer period is assigned to a buffer. CONSTITUTION:A frame memory 30 stores first and second data included in first and second video signals, and a buffer 80 stores the second data being input and output. A time indicating means 10 outputs a blanking period or an effective period of the first video signal as a timing signal. A time division control means 20, receiving a request for the assignment of transfer periods for inputting and outputting between the frame memory 30 and the buffer 80 for the second data outputs from the buffer 80, outputs a transfer permission to the buffer 80 in order to assign one side period out of informed periods by the time indicating means 10. The buffer 80 submits the request for the assignment of the transfer periods to the time division control means 20, and performs the input and output to and from the frame memory 3 of the second data, when the transfer periods are assigned.

摘要： PURPOSE:To prevent picture quality degradation accompanying the interpolation of an encoding stopping time and to obtain satisfactory picture quality by prohibiting a cropping by an image dissecting degree at the encoding stopping time. CONSTITUTION:When an encoding stop is obtained, a sub-sample and a field frame drop are prohibitted and they are not executed. Thus, at the encoding stopping time, forecasting error signals 54 are wholly zero, a demodulating signal 158 is equal with a forecasting signal 156 between frames. Accordingly, while the encoding stop is executed, the interpolating signal of of an (n)-th frame is repeatedly outputted. Then, even how much fields the encoding stop is executed over, a border between a black circle mark and a white circle mark is not faded away.

摘要： PURPOSE:To contrive the improvement for deterioration of a picture quality due to the correction of a transmission error by omitting an unnecessary rewriting after the completion of a matching between a transmitting device and a receiving device. CONSTITUTION:The receiving device calculates the parity signal of every frame, and compares it with the parity signal from the transmitting device, but when a notice saying that a rewrite signal for a range (b) has been received and a frame memory has been updated and a discordance between the transmitting and the receiving side has been eliminated, is transmitted by the termination time t2 of the second frame period of the transmitting device, it is secured that the transmission error is corrected even if the rewrite information for the ranges (c), (d) is not transmitted. Besides, when the notice saying that the discordance between the transmitting and the receiving side has been eliminated, is too late for the time t2, the transmission of the rewrite information for the range (d) can be omitted by the notice transmitted during the third frame period. Thus, by continuing to refer to a transmission error detection signal during the transmission period of the rewrite information as well, and by omitting the transmission of the rewrite information after the completion of the error correction, the picture quality of a received picture can be improved.
