Information transmission method, information processing method, information transmission system, and data processing apparatus

Abstract

A personal computer that is a controller transmits a reserve request for reserving a remote control. An MD recorder/player that is a target sets a reserve mode corresponding to the reserve request. In other words, the MD recorder/player prohibits another controller from performing a remote control by another controller. In addition, the MD recorder/player prohibits local key operations other than reproduction keys, a stop key, and an eject key. Thus, only the personal computer can perform an operation control for updating for example TOC information of the MD recorder/player. Thus, a mismatch of TOC information due to a remote control of another controller and a local key operation can be prevented from taking place between the personal computer and the MD recorder/player.

       36 . An information processing apparatus of an information processing system, having a plurality of information processing apparatuses connected through a data bus corresponding to a predetermined communication format, for performing a remote control with data and various commands transmitted and received between the information processing apparatuses, comprising: 
 download data transmitting means for transmitting download data that is downloaded and recorded to another information processing apparatus as a data recording apparatus;    download start/completion request command transmitting means for generating and transmitting a download start request command when the transmission of the download data starts and for generating and transmitting a download completion request command when the transmission of the download data is completed: and    reserve request command transmitting means for generating a reserve request command for requesting said the local information processing apparatus for a reservation of a remote control against the data recording apparatus and transmitting the reserve request command to the data recording apparatus before the download start request command is transmitted.    
   
   
       37 . The information processing apparatus as set forth in  claim 36 . 
 wherein the data bus corresponding to the predetermined communication format is an IEEE 1394 bus.    
   
   
       38 . The information processing apparatus as set forth in  claim 36 . further comprising: 
 reserve cancellation request command transmitting means for generating a reserve cancellation request command for requesting the data recording apparatus for a cancellation of the reservation of the remote control and transmitting the reserve cancellation request command thereto after the download completion request command is transmitted.    
   
   
       39 . The information processing apparatus as set forth in  claim 36 . 
 wherein the data recording apparatus permits the information processing apparatus to reserve the remote control corresponding to a download start request command received from the information processing apparatus, and    wherein the information processing apparatus causes said reserve request command transmitting means not to transmit the reserve request command.    
   
   
       40 . The information processing apparatus as set forth in  claim 36 . further comprising: 
 receiving means for receiving a rejection response transmitted from the data recording apparatus, the rejection response representing a rejection of the reserve request for the remote control by the information processing apparatus, and    presentation means for presenting that the remote control of the data recording apparatus is prohibited, when the rejection response is received by said receiving means.

       85 . An information processing method for an information processing apparatus of an information processing system, having a plurality of information processing apparatuses connected through a data bus corresponding to a predetermined communication format, for performing a remote control with data and various commands transmitted and received between the information processing apparatuses, the information processing method comprising the steps of: 
 transmitting download data that is downloaded and recorded to another information processing apparatus as a data recording apparatus (as download data transmitting step);    generating and transmitting a download start request command when the transmission of the download data starts and for generating and transmitting a download completion request command when the transmission of the download data is completed (as download start/completion request command transmitting step); and    generating a reserve request command for requesting the local information processing apparatus for a reservation of a remote control against the data recording apparatus and transmitting the reserve request command to the data recording apparatus before the download start request command is transmitted (as reserve command transmitting step).    
   
   
       86 . The information processing method as set forth in  claim 85 , 
 wherein the data bus corresponding to the predetermined communication format is an IEEE 1394 bus.    
   
   
       87 . The information processing method as set forth in  claim 85 , further comprising the step of: 
 generating a reserve cancellation request command for request the data recording apparatus for a cancellation of the reservation of the remote control and transmitting the reserve cancellation request command thereto after the download completion request command is transmitted (as reserve cancellation request command transmitting step).    
   
   
       88 . The information processing method as set forth in  claim 85 . 
 wherein the data recording apparatus permits the information processing apparatus to reserve the remote control corresponding to a download start request command received from the information processing apparatus, and    wherein the information processing apparatus causes the reserve request command transmitting step not to transmit the reserve request command.    
   
   
       89 . The information processing method as set forth in  claim 85 , further comprising the steps of: 
 receiving a rejection response transmitted from the data recording apparatus, the rejection response representing a rejection of the reserve request for the remote control by the information processing apparatus (as receiving step), and    presenting that the remote control of the data recording apparatus is prohibited, when the rejection response is received at the receiving step (as presentation step).
