[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiver with a transmission function for remotely controlling another receiver from a long distance, and a receiver remotely controlled by a receiver with a transmission function from a long distance.

[0002]

2. Description of the Related Art Conventionally, a receiver used in an environment for receiving broadcast data of a predetermined broadcast channel for broadcasting a digital broadcast program or the like includes a portable receiver carried by a user and a user's portable receiver. 2. Description of the Related Art An on-vehicle receiver used in a vehicle and a stationary receiver installed and used in a user's home are known.

[0003] A method has been proposed in which an electric device in a house is operated by telephone from a place outside the home. According to this method, by operating the telephone while referring to the operation correspondence list and the like from outside the home, the user can operate the electric equipment at home, for example, lighting equipment, air conditioning equipment, automatic hot water supply of a bath, and the like according to the operation content. You can do it.

[0004]

However, in a stationary receiver installed and used in a user's home, the power is turned on and activated, a predetermined broadcast channel is selected, and the program data is transmitted. Must be operated directly from the stationary receiver or from a short distance using the attached remote control device. That is, the user cannot remotely control the stationary receiver from a long distance such as when going out.

[0005] Therefore, when the user returns to a house or the like where the stationary receiver to be operated is installed, the user enters the room and directly operates the stationary receiver or uses the attached remote control device to access the nearby receiver. Operate from a distance, etc., turn on the power and start up,
Since it is necessary to select a predetermined broadcast channel and receive program data, it takes time to return to a desired broadcast program after returning home. There is inconvenience that you cannot do it.

[0006] For example, in a case where a vehicle-mounted receiver receives program data of a predetermined broadcast channel and views the broadcast program, etc., the user may return home from a place where he / she is away from home and install the stationary receiver installed at home. It takes time from the time you return home to complete the operation of the stationary receiver to watch the broadcast program of the same broadcast channel on the machine, so return to the home where the stationary receiver is installed. However, it is not possible to immediately watch the continuation of a broadcast program that has been viewed on a car-mounted receiver until returning home.

[0007] In addition, a portable receiver used by being carried by a user or a car-mounted receiver used by being carried in a user's car is limited in size and weight. Few of them have a function of recording / recording program data such as talks of broadcast programs, music and video scenes. Even if it has a function of recording / recording the program data being received, the capacity of the recording medium is small, so that the recording / recording time is limited, and a large amount of program data cannot be recorded.

Therefore, in a portable receiver or an on-vehicle receiver, when a broadcast program being received is being viewed, program data of the broadcast program being viewed is recorded / recorded.
Even when recording is desired, it is difficult to freely record / record a large amount of program data.

On the other hand, stationary receivers are premised on installation in a user's home, and many of them have a relatively small size, weight, etc., and have a sufficient recording capacity. If the user wants to record / record the program data of the broadcast program while the user is watching the broadcast program being received, the user can directly connect the stationary receiver installed in the home. It must be operated or operated from a short distance by the attached remote control device.

[0010] That is, since the stationary receiver installed in the home cannot be remotely operated from a long distance such as when away from home, the user is receiving the signal using the portable receiver or the on-vehicle receiver while away from home. When watching a broadcast program, the program data of the broadcast program being viewed cannot be recorded by the stationary receiver. In other words, a user can simply watch a broadcast program on a portable receiver or a car-mounted receiver while away from home, and can freely record program data of the broadcast program as well as at home. Impossible.

Further, even in the case of operating the electrical equipment in the home by telephone from outside, it is not at all possible to operate the stationary receiver in the home from the outside telephone as described above. Not intended. what if,
Even if you operate the stationary receiver by operating the phone from outside, you must operate the phone while referring to the operation correspondence list, etc., which complicates complicated operation procedures, Extremely inconvenient.

A second object of the present invention is to provide a receiver that is remotely controlled from a long distance by another receiver. A third object of the present invention is to provide a receiver which can be remotely operated by another receiver from a long distance and record received program data. A fourth object of the present invention is to remotely control a remote control by another receiver,
An object of the present invention is to provide a receiver capable of recording program data retroactively from the present time when recording received program data. A fifth object of the present invention is to remotely control a remote program by another receiver from a long distance, and when recording received program data, program data such as a talk, a song or a video scene in a broadcast program to be recorded is recorded from the beginning. It is to provide a receiver capable of recording.
