Abstract: A computer (1) is connected to VTR units (2, 3) and a CRT monitor (4) through lines (5-7). Each of the computer (1) and the units (2, 3) to be controlled thereby is provided with a clock means (10) for sharing the same time. The computer sends to the VTR unit (2, 3) a command for releasing record pause state and starting the record operation at time T1. After the VTR unit (2, 3) started the record operation, when the counter value became x, the VTR unit (2, 3) sends time Tx to the computer (1). The computer (1) computes formula D = Tx - T1 -x so as to obtain delay time D.

Abstract: There is provided a method of controlling communication for a communication system for connecting a plurality of electronic apparatuses through a communication control bus and allowing data communication between those electronic apparatuses wherein each of the electronic apparatuses performs connection control through the execution of a connection control command carried out by writing connection control information in a predetermined storage means of its own or another electronic apparatus. The electronic apparatuses which attempt to write the connection control information transmit the write instructions in a predetermined storage means. The storage means which has received the write instructions executes only the earliest write instruction and transmits responses indicating whether the execution of respective write instructions is successful or not.

Abstract: A COMMUNICATION SYSTEM COMPRISES ITEMS OF EQUIPMENT CONNECTED VIA A BUS CAPABLE OF TRANSFERRING COMBINATIONS OF CONTROL SIGNALS AND AV SIGNALS AS PACKETS WHILE PROVIDING AN ENVIRONMENT WHICH IS THE SAME AS AN ENVIRONMENT WHERE CONNECTIONS ARE MADE USING ANALOG SIGNAL LINES. A REGISTER DECIDED BY AN ADDRESS IS TAKEN TO BE A VIRTUAL PLUG FIR EACH ITEM IF EQUIPMENT. A PLUG ENABLE FOR AN INPUT PLUG (10) IS SET TO 1 AND A SYNCHRONOUS COMMUNICATION PACKET FOR THE AV SIGNAL FROM THE CHANNEL SET BY THE CHANNEL NUMBER IS RECEIVED. A PLUG ENABLE FOR AN OUTPUT PLUG (11) IS SET TO ONE AND THE SYNCHRONOUS COMMUNICATION PACKET FOR THE INFORMATION SIGNAL IS SENT TO THE CHANNEL SET BY THE CHANNEL NUMBER AT A TRANSMISSION SPEED DESIGNATED BY THE DR (DATA RATE) AT THE BANDWIDTH EXPRESSED BY "BANDWIDTH".(FIG 1)

Abstract: An information processing apparatus is connected to another information processing apparatus via a network and has at least one sub-unit for executing a predetermined function. A reservation is made for causing a tuner sub-unit of an IRD to receive a predetermined channel broadcast at a predetermined time and to record it on a VCR sub-unit of a DVCR via an IEEE-1394 serial data bus. Then, a controller of the IRD writes reservation information into a Resource Schedule Board (RSB) built into a Bulletin Board Subunit (BBS) of the IRD and also writes reservation information of the VCR sub-unit into a RSB built into a BBS of the DVCR. With this arrangement, double-booking is prevented.

Abstract: In a digital tuner (1) a tuner subunit (11) selects a data stream of one or more programs from a data stream in which digital signals of a plurality of programs are multiplexed, and a 1394 interface (13) transmits the selected data stream to a 1394 serial bus (3). A logical output plug is set in the tuner subunit, and the data stream of the one or more programs is output to the 1394 interface from the output plug.

Abstract: An equipment unit having an interactive user interface is controlled by means of a simple apparatus. Data reproduced by a DVD player (400) is decoded. The decoded data is converted into a signal format such as DVC SD or MPEG2-TS along with information about such as a menu. The converted information is transmitted to a simple display device (500) through the 1394 digital interface. When a predetermined item in the menu displayed on the screen of the simple display device (500) is selected by operating a remote commander (300), a corresponding panel command such as "CURSOR UP" or "EXEC" is transmitted to the DVD player (400). The selected item is recognized by the DVD player (400) and necessary processing is executed.
