Abstract

An electronic mail on which a control command is interpolated is transmitted through a public line, received by a modem section of a gate way, converted to a digital data, and supplied to the control section. A CPU of the control section stores the received electronic mail in a RAM, and extracts the control command contained in the electronic mail. The CPU supplies a control signal corresponding to the control command to an interface section. The interface section controls an IR transmission section to transmit a signal corresponding to the control signal supplied from the CPU or outputs a signal through a connection line, and controls a video deck.

1 . A recording apparatus comprising:
 a receiver configured to receive from an electronic device, via an IP-based network, a first control information including at least one of an operation mode of the recording apparatus, a starting time to start an operation of the recording apparatus, an ending time to end the operation of the recording apparatus or recording channel information;   a timer that provides a current time of the recording apparatus; and   control circuitry configured to start the operation of the recording apparatus in accordance with the first control information,   wherein said receiver is configured to receive a second control information, and   said control circuitry is configured to prevent the start of the operation of the recording apparatus when said second control information is received before the start of the operation of the recording apparatus.   
     
     
         2 . The recording apparatus of  claim 1 , wherein the control information is provided from the electronic device via a remote computer. 
     
     
         3 . The recording apparatus of  claim 1 , wherein the operation mode is a video recording reservation mode. 
     
     
         4 . The recording apparatus of  claim 1 , further comprising:
 a transmission device that transmits a confirmation electronic message that provides an indication of a confirmation of cancellation of a planned recording at said recording device.   
     
     
         5 . An electronic device comprising:
 a communication interface configured to send, via an IP-based network, a first control information that includes at least one of an operation mode of a recording apparatus, a starting time to start an operation of the recording apparatus, an ending time to end the operation of the recording apparatus or recording channel information;   a data input device configured to accept user input; and   control circuitry configured to format said first control information based on a first user input from the input section,   wherein said communication interface is further configured to send a second control information based on a second user input to prevent the start of said operation of the recording apparatus.   
     
     
         6 . The device of  claim 5 , wherein the electronic device is not a mobile device. 
     
     
         7 . The device of  claim 5 , wherein said communications interface receives at least a portion of said control information from a remote computer. 
     
     
         8 . An electronic device comprising:
 a communication interface configured to send control information to a recording apparatus; and   processor circuitry configured to send, via said communication interface, a first control information including at least one of an operation mode of the recording apparatus, a starting time to start an operation of the recording apparatus, an ending time to end the operation of the recording apparatus or recording channel information,   wherein said processor circuitry is further configured to send a second control information to prevent the start of said operation of the recording apparatus.   
     
     
         9 . The electronic device of  claim 8 , wherein
 the operation mode is a video recording reservation mode.   
     
     
         10 . A method to control a recording apparatus comprising:
 receiving a first control information including at least one of a starting time to start an operation of the recording apparatus, an ending time to end the operation of the recording apparatus, an operation mode of the recording apparatus, or recording channel information;   starting said operation of the recording apparatus with control circuitry in accordance with the first control information;   receiving a second control information; and   preventing with the control circuitry the start of said operation of the recording apparatus when the second control information is received before the start of said operation of the recording apparatus.   
     
     
         11 . The method of  claim 10  further comprising:
 transmitting a confirmation electronic message that provides an indication of a confirmation of cancellation of a planned recording at said recording apparatus. 
 
     
     
         12 . A method to control an electronic device comprising:
 sending a first control information including at least one of an operation mode of a recording apparatus, a starting time to start an operation of the recording apparatus, an ending time to end the operation of the recording apparatus, or recording channel information; and   sending with communications circuitry a second control information before the start of said operation of the recording apparatus to prevent the start of said operation of the recording apparatus.   
     
     
         13 . The method of  claim 12 , further comprising:
 receiving a confirmation electronic message that provides an indication of a confirmation of cancellation of a planned recording at said recording apparatus.
