A television control unit for controlling the main unit, a decoder box for decoding a signal other than a normal television signal and displaying it on the television, a decoder box control unit for controlling the decoder box, and displaying a signal output from the television main unit or the decoder box Equipped with a display and process the timing and content of the remote control signal instead of transmitting the remote control signal as it is, to facilitate the handling of the decoder box and to simplify the communication between the decoder box and the TV main unit. It is characterized by.

According to the present invention, it is possible to provide a communication function between the decoder box and the television main body, which has a small communication amount and does not cause a timeout mismatch.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is a decoder box and a television main unit which have a built-in decoder box and receive a remote control operation signal from a user by the television main unit and transmit the signal to the decoder box. In communication with the remote controller, the remote control operation signal is not transmitted as it is, but the timing and contents are processed and transmitted.
This has the effect of simplifying communication between the decoder box and the television body.

According to a second aspect of the present invention, there is provided a remote control signal receiving unit for receiving a remote control operation signal from a user, a television control unit for transmitting a remote control signal to a decoder box or controlling a television main unit, A decoder box that decodes the signal of
By providing a decoder box control unit that controls the decoder box and a display that displays the signal output by the TV main unit or the decoder box, when the user performs a remote control operation that requires a timeout, by transmitting only the confirmed contents This has the effect of facilitating the correspondence of the decoder box and simplifying the communication between the decoder box and the television body.

According to a third aspect of the present invention, the decoder box has the same configuration as that of the second aspect, and a remote control operation signal required for determination is continuously transmitted to facilitate the correspondence of the decoder box. This has the effect of simplifying the communication with.

According to a fourth aspect of the present invention, the configuration of the second aspect is the same as that of the second aspect, wherein the remote control operation signal is transmitted only at the start and end of the remote control operation, so that the decoder box can be easily handled. This has the effect of simplifying the communication with.

The invention according to claim 5 has the same configuration as that of claim 2, and has an effect of facilitating the correspondence of the decoder box by transmitting the information to the decoder box at the time of timeout. Hereinafter, embodiments of the present invention will be described with reference to FIGS.

(Embodiment) Hereinafter, a first aspect of the present invention will be described.
An embodiment of the invention described in claims 2, 3 and 4, and 5 will be described with reference to FIG.

FIG. 1 is a block diagram. In FIG. 1, a television receiver 1 performs an operation of simplifying communication between a decoder box and a television main body. It comprises a signal receiving unit 3, a television control unit 4, a decoder box 5, a decoder box control unit 6, and a display 7.

[0013]

Next, specific examples of the present invention will be described.

Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a transition diagram of communication in the first embodiment.

In FIG. 1, a remote control signal receiving section 3 receives a remote control signal and transmits it to a television control section 4. The television control unit 4 transmits a remote control signal to the decoder box control unit 6 at an appropriate timing, and the decoder box displays a video signal on the display 7 according to the result.

FIG. 2 shows a remote control signal received with respect to a time flow from top to bottom and communication contents from the television control unit to the decoder box control unit. "-/-
"-" Is a two-digit remote control key indicating that the user inputs a two-digit number, and the two-digit key pressed continuously within a certain time after pressing this key determines the two-digit number. I do.

First, "-/-" is pressed, the "2" key is pressed within a certain period of time, and the "3" key is pressed within a certain period of time. I do. Immediately thereafter, the television controller communicates "23" to the decoder box controller.

(Embodiment 2) Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a transition diagram of communication in the second embodiment.

FIG. 3 shows a remote control signal received from time to time from the top to the bottom and communication contents from the television control unit to the decoder box control unit. First,
"-/-" Is depressed with the "2" key within the next certain time, and the "3" key is depressed within the next certain time, so "23" is determined at this time.

Immediately after that, the television control section returns “− / −”.
"-", "2", and "3" are communicated successively to the decoder box control unit. If there is no input for a fixed time after the "2" key is pressed, a timeout occurs and "-/-" becomes invalid, and if "3" is subsequently pressed, only "3" is communicated.

(Embodiment 3) Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a transition diagram of communication in the third embodiment.

FIG. 4 shows a remote control signal received with respect to a time flow from top to bottom and communication contents from the television control unit to the decoder box control unit. In a case where the user presses the position up key continuously from a certain time t1 to a time t2, the remote control reception is continuously performed from a certain time t1 to a certain time t2 with the “Pos UP” command.

At time t1, the television control section reads "Pos U
"PosUP Press" once after receiving "P" command
After sending the command to the decoder control unit, do not communicate,
At time t2, when the “Pos UP” command is interrupted, “Pos UP Release” is transmitted once. This requires only two communications.

(Embodiment 4) Hereinafter, a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a transition diagram of communication in the fourth embodiment.

FIG. 4 shows a remote control signal received with respect to time flow from top to bottom and communication contents from the television control unit to the decoder box control unit. When the user presses "5" at a certain time t1 to change the position to 5, a position number and information on a program currently being broadcast are displayed on the on-screen for a certain period of time (t in this case).

Here, the position number is displayed on-screen by the television control unit, but the information on the program (broadcast time, program name) is displayed on-screen by the decoder control unit having the program information. . The on-screen display is stopped after the time t, but the time t is measured only by the television control unit. At the time t2, the command “OSD Off” is transferred from the television control unit to the decoder control unit.

Thus, the on-screen disappears at the same time, but if the time t is to be measured by the decoder control unit, a clock function is required for both. There are problems such as the need to change.

[0028]

As described above, according to the television receiver of the present invention, the remote control operation signal from the user is not transmitted as it is, but the timing and the contents are processed and transmitted. This has the advantageous effect of simplifying the communication between them and preparing the decoder box.
