摘要： PROBLEM TO BE SOLVED: To provide a communication control system that can relieve a load of a CPU of a device to be controlled in a transmission system or the like, adopting the 'Sony disk 9-pin protocol'. SOLUTION: An AV server 30 is provided with a serial communication I/F 1 having a storage means 1a for temporarily storing a prescribed number of character strings sent from a transmission means, a detection means 2 which detects whether or not the interval between characters sent from the transmission means is a time to be judged as a communication error or over, and with a reception means 3 that receives the character string via the I/F 1. The I/F 1 applies 1st interruption to the reception means 3 every time the storage means 1a stores the characters. When the detection means 2 detects that the interval is a time to be judged as the communication error or over, the detection means 2 applies 2nd interruption to the reception means 3. The reception means 3 receives characters of the character string on the basis of the 1st interruption and judges whether or not the reception of all the character string is finished, and judges the presence of a communication error on the basis of the 2nd interruption.

摘要： PROBLEM TO BE SOLVED: To provide an AV data processing controller by relieving a procedure load in the case of revising plural related instructions in a batch, so as to avoid missing and mistake in the revision procedure. SOLUTION: Control instructions with the same identifier added to them with respect to relating instructions are given to an AV data processing controller 1 from an application 106. Furthermore, an instruction relating the identifier to a trigger generated by a contract input-1 is received. On the occurrence of the contact input-1, all the control instructions including the identifier are executed. Furthermore, the relation between the contact input-1 and the identifier of all the control instructions is invalidated. Even on the occurrence of the contact input-1, all the related control instructions are not executed. The control instructions are executed by using IDCs 102-1 to 102-3 to control controlled devices 104-1-104-7.

摘要： PURPOSE: To improve visual characteristic of an image by detecting a characteristic of a frequency distribution as to information divided for each block, deciding a quantization step size and processing the information. CONSTITUTION: Video data Vi are divided into specific sub-blocks Sb by a block processing circuit 2. The sub-blocks Sb are given to a DCT circuit, in which the data in the blocks are converted into data from a DC component to a harmonic AC component and the converted data written in a frame memory 4. On the other hand, the coefficient data given to a classification circuit 5 are classified into low and high frequency AC coefficients, after they are processed such as arithmetic operation processing by an arithmetic circuit 9, a minimum value detection circuit 13, an averaging circuit 15 and a multiplier circuit 18 or the like and reference quantization step size data Qstep are decided. The reference quantization step size data Qstep are given to a quantization circuit 19 and coefficient data of the memory frame 4 are given to the quantization circuit 19. Then the coefficient data are quantized based on the reference quantization step size data Qstep in the quantization circuit 19 and the quantized data are outputted via a variable length coding circuit 20.

摘要： PROBLEM TO BE SOLVED: To construct a data processing system with excellent responsiveness which can be easily controlled in real time. SOLUTION: An input buffer device 40 for temporarily storing AV input data, output buffer device 50 for storing output AV data, and storage devices 60 and 70 for AV data are connected through a sub-network 59. A server controller 90 for controlling each device is connected with the sub-network. The input buffer device, output buffer device, and storage devices are connected through the sub-network so that the setting places of the devices can not be limited. The number of input and output channels is decided by the sub-network, and the sufficient number of channels can be ensured. The output buffer and the storage devices are hierarchically controlled, and a file is hierachized. Thus, the AV server device with a large capacity and excellent responsiveness can be constructed at well-balanced costs. Even at the time of using a hard disk device as the storage device, real-time property for a hard disk drive is not required.
