A data demultiplexer includes a write controller, a memory, an analyzing processing unit, and transfer control units. The write controller writes packets which have arrived thereat into the memory in the order of arrival and sends the write information to the analyzing processing unit. The analyzing processing unit analyzes packets in the order of arrival on the basis of the write information and sends only the result of analysis to the transfer control units. On the basis of the result of analysis, the transfer control units send data read from the memory in the order of packet arrival to the decoder. A data demultiplexer capable of reducing the processing in the analyzing processing unit can be provided.

The present invention efficiently executes a transfer process from a flash memory to an optical disc. A recording control apparatus includes a UDF file system section that configures a UDF file system on the flash file system of a flash memory and an application format section that converts video and audio data into a file group conforming to the DVD application format and manages it on the UDF file system. When copying the data recorded in the flash memory to a DVD, a management information switching section of the apparatus converts the logical addresses of the flash memory into the logical addresses of the DVD. A DVD buffer control section converts the data recorded in an array of 64 Kbytes that is the recording unit of the flash memory into an array of 32 Kbytes that is the recording unit of the DVD and transfers them to the DVD drive.

In order to drive a PC and a cam-coder communicating with each other by adopting a Bluetooth technique to carry out mutual authentication processing, the user presses an authentication button of the PC and an authentication button of the cam-coder simultaneously. An authentication program of the PC detects an on time to turn on the authentication button of the PC and an off time to turn off the button. Likewise, an authentication program of the cam-coder detects an on time to turn on the authentication button of the cam-coder and an off time to turn off the button. The detected on and off times are exchanged between the PC and the cam-coder. If a difference between the on times and a difference between the off times are each found to be within a predetermined range, a result of the mutual authentication processing is considered to be positive. In this way, the mutual authentication processing can be carried out with ease.

This invention is a recording medium recording method for an optical disc or the like. Every time one VTS is prepared, padding processing is executed to secure a recording area for new TMP_VMGI following that VTS and for VTSI and VTSM VOBS of the subsequent title. As, every time one VTS is prepared, new TMP_VMGI following that VTS is recorded, TMP_VMGI is recorded at the position that is added to the number of VTSs. Therefore, even when the management information becomes unreadable because of update exceeding the rewriting durability of the medium with respect to the recording area of TMP_VMGI on the innermost side, the management information can be read from TMP_VMGI recorded in the other recording areas and the finalizing processing can be executed.

A bus management node 11 has a register for channels in use REG1 and a bus capacity register REG2. Before starting the synchronous communication, each node 12 transmits a read-out command to the register for channels in use REG1 in order to read out their contents for ascertaining the number of the un-used channel and the residual capacity. If there is any un-used channel and any residual bus capacity, the node 12 transmits write commands to these registers REG1 and REG2 so that the number of the channel to be in use and the capacity of the bus to be in use will be stored in the register for channels in use REG1 and the bus capacity register REG2. This enables bus management to be achieved easily in a system performing synchronous communication between plural nodes connected to the bus.

There are provided: a unit data group formation section for forming a unit data group comprising at least one piece of unit data; a thumbnail image generation section for generating a thumbnail image for unit data; a link information generation section for generating unit data link information to link with each unit data forming the unit data group; a data group generation section for generating a data group comprising a unit data group and unit data link information; and a closed session processing section for performing a closed session process so that other reproducing apparatuses can read an optical disc recording at least one data group. The closed session processing section generates a menu image including the thumbnail image based on the unit data, generates menu image link information for linking with the menu image, and records the menu image and the menu image link information on an optical disc.

Information created by a device and recorded on a recording medium and information supplied externally to the device and recorded on the recording medium are classified according to creation date and time information. Each image data file recorded on the recording medium has an original recorded file flag added thereto which indicates whether the image data file is obtained by photographing using the device. Photographing date and time information is added to an image data file obtained by photographing using the device. Obtainment date and time information is added to an image data file supplied externally. In a classification process, an original recorded file flag is checked; an obtainment date and time is used for an image data file obtained externally; a photographing date and time is used for an image data file obtained by photographing; a classification process is performed; and a result of the classification process is displayed.
