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.

       22 . 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: 
 operation information transmitting means for transmitting an operation control command to a data recording and reproducing apparatus as another information processing apparatus that allows a predetermined process for reproducing data from a predetermined record medium, recording data thereto, or editing data recorded thereon, the operation control command causing a remote control of a predetermined operation of the data recording and reproducing apparatus to be performed, and    reserve request command transmitting means for generating a reserve request command for requesting the local information processing apparatus for a reservation of a remote control against the data recording and reproducing apparatus and transmitting the reserve request command to the data recording and reproducing apparatus.    
   
   
       23 . The information processing apparatus as set forth in  claim 22 , 
 wherein the data bus corresponding to the predetermined communication format is an IEEE 1394 bus.    
   
   
       24 . The information processing apparatus as set forth in  claim 22 , 
 wherein said reserve request command transmitting means transmits the reserve request command when said operation information transmitting means is activated and operated.    
   
   
       25 . The information processing apparatus as set forth in  claim 22 , further comprising: 
 reserve cancellation request command transmitting means for generating a reserve cancellation request command for requesting the data recording and reproducing apparatus for a cancellation of the reservation of the remote control against the data recording and reproducing apparatus and transmitting the reserve cancellation request command thereto.    
   
   
       26 . The information processing apparatus as set forth in  claim 25 , 
 wherein said reserve cancellation request command transmitting means transmits the reserve cancellation request command when said operation information transmitting means is deactivated.    
   
   
       27 . The information processing apparatus as set forth in  claim 22 , further comprising: 
 receiving means for receiving a rejection response transmitted from the data recording and reproducing 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 and reproducing apparatus is prohibited, when the rejection response is received by said receiving means.

       71 . 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 an operation control command to a data recording and reproducing apparatus as another information processing apparatus that allows a predetermined process for reproducing data from a predetermined record medium, recording data thereto, or editing data recorded thereon, the operation control command causing a remote control of a predetermined operation of the data recording and reproducing apparatus to be performed (as operation information 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 and reproducing apparatus and transmitting the reserve request command to the data recording and reproducing apparatus (as reserve request command transmitting step).    
   
   
       72 . The information processing method as set forth in  claim 71 , 
 wherein the data bus corresponding to the predetermined communication format is an IEEE  1394  bus.    
   
   
       73 . The information processing method as set forth in  claim 71 , 
 wherein the reserve request command transmitting is performed by transmitting the reserve request command when the operation information transmitting step is performed.    
   
   
       74 . The information processing method as set forth in  claim 71 , further comprising the step of: 
 generating a reserve cancellation request command for requesting the data recording and reproducing apparatus for a cancellation of the reservation of the remote control against the data recording and reproducing apparatus and transmitting the reserve cancellation request command thereto (as reserve cancellation request command transmitting step).    
   
   
       75 . The information processing method as set forth in  claim 74 , 
 wherein the reserve cancellation request command transmitting step is performed by transmitting the reserve cancellation request command when the operation information transmitting step is completed.    
   
   
       76 . The information processing method as set forth in  claim 71 , further comprising the steps of: 
 receiving a rejection response transmitted from the data recording and reproducing 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 and reproducing apparatus is prohibited, when the rejection response is received at the receiving step (as presentation step).
