Abstract: This invention converts Packbit-encoded data into new Packbit-encoded data which allows to have a throughput=M. a extraction unit separates inputted encoded data into length information and data information, and outputs them to a conversion unit. The conversion unit has a count unit which cumulatively counts the number of output data after decoding indicated by the separated length information. The conversion unit divides length information of interest into first length information and second length information as needed, outputs the first length information, and sets the second length information as an initial count target to be counted by the count unit, so that the counted number N of output data reaches the throughput=M. The conversion unit combines the generated length information and the separated data information, and outputs new Packbit-encoded data.

Having been instructed to end the entry processing, the wireless access point device switches into the sending of the beacon with the group identification information hidden, thereby hiding the group identification information from other wireless access point devices.

Abstract: An information display apparatus which reproduces images stored in a detachable recording medium acquires file identifying information which identifies a file stored in the recording medium. Also, it determines whether or not specific attribute information about the file identified by the file identifying information exists and acquires attribute information existence information which indicates the presence or absence of the attribute information. Then, the information display apparatus generates an image file list which associates the file identifying information with the attribute information existence information. The information display apparatus acquires, from the recording medium, specific attribute information about files determined to have attribute information by the attribute information existence information among files recorded in the image file list and determines a reproducing method of files stored in the recording medium based on the file identifying information and the attribute information.
