摘要： A video/audio encoding unit encodes an inputted video/audio signal in a format compliant with a predetermined technical standard. A differential signal output unit outputs the encoded data in the form of a differential signal defined by the predetermined technical standard. The differential signal output unit appends the data encoded by the video/audio encoding unit to a data transmission unallocated region of a communication line defined by the predetermined technical standard and then transmits the resulting data. Because the data transmission unallocated region, which is not directly used in normal data transmission, is thus effectively utilized in data transmission, a larger volume of information can be transmitted and received.

摘要： An inter-record alteration detection code verification unit 36 calculates an inter-record alteration detection code by merging a record alteration detection code stored in a record to read from a database 34 and a record alteration detection code in the immediately previous record so as to generate a code and applying a predetermined hash operation to the generated code. The verification unit verifies whether the calculated inter-record alteration code coincides with the inter-record alteration detection code stored in the record to read. If they coincide with each other, data is determined to be not altered.

摘要： In a wireless network structure which includes a wireless LAN device having a base station function (host device) which is compliant with IEEE802.11h and at least one wireless LAN device having a terminal function (slave device) which is not compliant with IEEE802.11h, the incompliant terminal transmits a probe request to the base station for confirming the presence of the base station. When the base station has dynamically switched its channel (frequency), a probe response is not returned from the base station to the terminal. Thus, the incompliant terminal transmits a probe request through a different channel in order to confirm the presence of the base station. The incompliant terminal repeats the above channel search process till the base station is found.
