Program recording reservation system, recording apparatus, and controller apparatus

A recording apparatus including a recorder to record a reservation of a broadcast program, the recording apparatus comprising:

• the recorder including a plurality of tuners to record a plurality of broadcast programs;
• a bi-directional network interface to communicate program-recording-related information with a remote controller;
• a recording management section to
• obtain, while recording data based upon a predetermined operation, a remaining recordable capacity of the recorder, a recording reservation list of programs that are scheduled to be recorded by the recorder, and an average recording bit rate for each of a plurality of recording modes,
• compute, while recording the data based on the predetermined operation, a necessary scheduled recording capacity for the programs that are scheduled to be recorded based on the average recording bit rate for each of the plurality of recording modes and the recording reservation list of programs that are scheduled to be recorded, and
• while recording the data based upon the predetermined operation, continuously compare the necessary scheduled recording capacity with the remaining recordable capacity of the recorder to provide an indication of insufficient capacity;
• a display section to display a message of insufficient remaining recordable capacity of the recorder and a first choice for stopping the predetermined operation, a second choice for editing or deleting recording reservations, and a third choice for continuing the predetermined operation, based on the indication of insufficient capacity;
• and
• an operation section to stop the predetermined operation when the first choice is selected, edit or delete the recording reservations when the second choice is selected, and continue the predetermined operation when the third choice is selected.

A controller to set a recording reservation to a recording apparatus including a recorder and a plurality of tuners to record a plurality of broadcast programs, the controller comprising:

• a bi-directional network interface to communicate program-recording-related information with the recording apparatus;
• a recording management section to
• obtain, while recording data based upon a predetermined operation, a remaining recordable capacity of the recorder, a recording reservation list of programs that are scheduled to be recorded by the recorder, and an average recording bit rate for each of a plurality of recording modes,
• compute, while recording the data based upon the predetermined operation, a necessary scheduled recording capacity for the programs that are scheduled to be recorded based on the average recording bit rate for each of the plurality of recording modes and the recording reservation list of programs that are scheduled to be recorded, and
• while recording the data based upon the predetermined operation, continuously compare the necessary scheduled recording capacity with the remaining recordable capacity of the recorder to provide an indication of insufficient capacity;
• a display section to display a message of insufficient remaining recordable capacity of the recorder and a first choice for stopping the predetermined operation, a second choice for editing or deleting recording reservations, and a third choice for continuing the predetermined operation, based on the indication of insufficient capacity;
• and
• an operation section to stop the predetermined operation when the first choice is selected, edit or delete the recording reservations when the second choice is selected, and continue the predetermined operation when the third choice is selected.
