    Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for processing media data transmitted inside a data communication medium. SOLUTION: It is shown how to transmit the sequence of media data with the set of data related to time according to a certain transmitting protocol. This set of data contains the sequence of data, which are related to time, related to the sequence of these media data related to time. A digital processing system utilizes this set of data and can transmit the sequence of media data related to time(by that transmitting protocol and a packet generated according to the set of these data, for example).

    Abstract: PROBLEM TO BE SOLVED: To perform a point click system without putting the hands away from a keyboard by positioning a cursor with one thumb and selecting an image with the other thumb while placing the fingers of both the hands except the thumbs at their home keys when operating the cursor with both the hands. SOLUTION: A cursor controller 12 (track ball 32, function start button 31, and lower button 33) is provided at a palm rest part 9 provided on a main housing 1 which is closer to a user oppositely from the keyboard 11 so that both the hands of the user reach a cursor controller 12 during operation on the keyboard 11. To operate the cursor with both the hands, the cursor is positioned with one thumb and an image specified with the cursor is selected with the other thumb while the fingers of both the hands are left at their home positions. To operate the cursor with one hand, the one hand is put away from the home positions, the cursor is positioned with the one hand, and an image is selected.

    Abstract: PURPOSE: To provide an inexpensive means for decoding the data of a variable length in real time and a further efficient solving method for performing the decoding of the variable length in real time. CONSTITUTION: These method and device for decoding the code word (VLC) of the variable length by reading the VLC are provided. The VLC is provided with the maximum length of X bits. The VLC is used as an index to a first table, and in this case, the first table is provided with a value decoded for all the possible VLCs provided with Y bits not equal to any of the values of a first set. The Y is typically smaller than X and it is composed of the extremely important bit of the VLC in a preferable execution example. In the case that the first Y pieces of the bits of the VLC are not equal to any of the values of the first set, a second value is returned from the first table. In the case that the first Y pieces of the bits of the VLC are equal to one of the values of the first set, a pointer to a second table is returned from the first table.

    Abstract: PURPOSE: To obtain a simple and also effective method for connecting plural peripheral equipments to HCOMP by transmitting data and a signal from a host computer(HCOMP) to a desired peripheral equipment through a bus. CONSTITUTION: Plural peripheral equipments 11-16 are connected to HCOMP 10 with a single cable 17. An extension address device 15 is provided with a common hard wired address(HWA) 35 and also with a peculiar extension address 29 for identification when HCOMP 10 addresses the individual device. At first, HCOMP 10 simply addresses one device by HWA 35. At this time, the whole devices having the same address are stopped. When HCOMP 10 transmits a coincident signal to the extension address of the specified device, the device becomes an operation state by HCOMP 10. After that, a command to the device is transferred to the device and executed only by HWA 35 without supplying the extension address on each occasion.
