Program reservation recording device, information providing server, program reservation information management server, program reception device, and program reservation recording system

Abstract

There is provided a program reservation recording device capable of reducing load on a server and performing program recording as is reserved by a user. Immediately before the reserved program is started and immediately before the end of it (S 1 ), the program reservation recording device makes a request to an information providing server connected via a general-purpose network so as to acquire the latest program list (S 2 ). The program reservation recording device compares the reservation information indicating the program reservation contents (start time, end time, etc.) to be stored in a memory with the latest program list acquired (S 3 ). If any mismatch is present, the reservation information is updated according to the program list (S 4 ).

Description

technical field [0001] The invention relates to a program reservation recording device, an information providing server, a program reservation information management server, a program receiving device and a program reservation recording system suitable for video recording reservation of playing programs. Background technique [0002] Up to now, there is a method of easily broadcasting programs on the program reservation and recording devices used in each family according to program information such as the broadcasting channel and program time (that is, broadcasting date, broadcasting start time, and broadcasting end time) of the program. The system of recording reservations is already known to the public. For example, Patent Document 1 (Japanese Patent Laid-Open No. Hei 9-180291), Patent Document 2 (Japanese Patent Laid-Open No. Hei 10-93936), Patent Document 3 (Japanese Patent Laid-Open No. Hei 10-155131), Patent Document 4 (Japanese Patent Laid-Open Publication No. 2002-3...

AI Technical Summary

Problems solved by technology

However, in this prior art, every time the program information is updated, the server must send the program information to each program reservation and recording device, so there is also the problem that the load on the server is still too large and unrealistic

[0007] In addition, in the existing program reservation and recording device, even if the program time has not been changed, due to interference from the recording medium to the program reproduction operation, or due to the interference of the use of the tuner that receives the program and outputs it to the monitor, there may be problems in which the program cannot be played. The problem of recording the program according to the appointment time

Moreover, in the prior art, a program reservation and recording device that can easily perform program reservations that not only reflects the user's wishes but also reflects the tendency of most users to program preferences is not known to the public.

Moreover, even if the program time is changed, the reserved program can still be recorded, and the program reserved recording device that automatically deletes useless programs other than the reserved program is not known to the public.
