摘要： PROBLEM TO BE SOLVED: To avoide influence due to an error of a padding part in data communication method and equipment based upon fixed length data format. SOLUTION: In the data communication method and equipment including a synchronizing word SW, an effective information I, information length information L indicating the length of the information I, and an error detection code CRC for parts excluding the word SW and having fixed length data format, the transmitting side calculates an error detection code CRC' corresponding to the information I or the information I and the information L in a padding(PAD) area, inserts the calculated CRC' in the PAD area and transmits the CRC'-inserted PAD area. When there is no error in error detection based upon the code CRC' even when an error is detected by error detection based upon the code CRC, the receiving side executes receiving processing for the information I by regarding the state as no error in the information I.

摘要： PROBLEM TO BE SOLVED: To suppress the power consumption of reception part to the minimum and to improve the validity of operation while adapting to a multiframe configuration by stopping supply of drive power to a demodulating means for a prescribed time when identification information shows another station. SOLUTION: A demodulating means 11 acquires a bit sequence by demodulating a radio signal modulated by the sequence of packets to which numerical value information showing the order or the quantity of following unit information and the identification information of its transmission destination are added to unit information. A communication control means 13 restores the sequence of packets from that bit sequence and extracts the unit information, numerical value information and identification information. Then, when the identification information shows the other station, a packet identififying means 15 finds the number of following unit information based on its numerical value information and the frame configuration and individually finds the difference between the product of that number and the length of packets and the maximum value of the rising time of the means 11. Then, a drive control means 17 stops supplying the drive power to all the parts or one part of the demodulating means 11 during the period equal to this difference.

摘要： PROBLEM TO BE SOLVED: To collectively search digital content in a DMS which is not provided with any information retrieval function nor any necessary retrieval attribute together with a DMS which is provided with a sufficient information retrieval function, in a DLAN. SOLUTION: The collective search function of a DMC or a DMP is configured to make a request for requesting search using the search function of the DMS to a DMS which is provided with a "sufficient search function", and to perform search on behalf of the DMS which is not provided with "sufficient search function" by using "index search". Thus, it is possible to achieve collective search regardless of whether or not the DMS to be searched is provided with the "sufficient search function" by dynamically switching the search request or the "index retrieval" according to whether or not the DMS to be searched is provided with the "sufficient retrieval function" in the collective search.
