By entering numbers in the program number and page number in advance and specifying the reservation number,
The teletext reservation function can perform the same function as inputting and specifying a series of numbers. This teletext reservation function is provided as a function of the teletext receiver, and the reserved contents can be displayed in a list.

If the teletext receiving apparatus configured as described above can also reserve channels for a television receiver, a more convenient reservation function can be provided.

By the way, is it possible to rewrite the display of the receiving channel on a television receiver? For example, by operating the display rewriting means, channel number 1 can be changed to 19.
", channel number 2 can be rewritten and displayed as "32". By combining such a television receiver with a teletext receiver, it is possible to display the channel, as well as the magazine number, program number, and page number of the teletext broadcast. Attempts have been made to book.

On the other hand, the text information transmitted by teletext is different when the TV channel is different, even if it is indicated by the same program number. must be notified by means of means. However, when combined with a television receiver equipped with display rewriting means, when the television receiver notifies the teletext receiver of the rewritten channel number, broadcast channel 1 and broadcast channel 2
However, if "19" is specified in the display rewriting, the teletext receiver will recognize that the channel has not changed, causing the inconvenience that it will not be able to receive the necessary information when the broadcast channel changes.

For this reason, in the above example, instead of displaying rewritten information, channel 1. -F-Yannel 2 information was being conveyed to the teletext receiver.

Problems to be Solved by the Invention However, with the above configuration, when reserving a teletext broadcast, only the channel number information of channel 1 and channel 2 is transmitted to the teletext receiving device.
When displaying reserved contents or setting reservations on a teletext receiver, only channels 1 and 2 can be displayed. On the other hand, those who use the reservation function memorize the channel with the rewritten information ("19" in the example above), and when making a reservation or referring to the reservation information, the person who uses the reservation function remembers the channel with the rewritten information ("19" in the above example), and when making a reservation or referring to reservation information, the person who uses the reservation function remembers the channel with the rewritten information ("19" in the above example). The problem was that the content could not be understood.

In view of the above-mentioned problems, the present invention provides a television receiver that can display the reservation using rewritten characters when reserving a teletext program including a television channel. .

Means for Solving the Problems In order to solve the above problems, the present invention adds information indicating channel changes to the teletext receiving section, and adds information indicating channel changes to the teletext receiving section, and adds information to the teletext receiving section when the power is turned on, when the display is rewritten, or when the reservation is changed. The content rewritten to the display on the teletext receiving unit is transmitted from the television receiver and the display rewriting means using a communication transmission means, and when the reservation is displayed, the reserved reception channel is displayed according to the contents of the display rewriting means. It was designed to do so.

Operation With the above configuration, it is possible to reserve a teletext program using the channel number whose display has been rewritten, and
Even if the display of different channels has been rewritten to the same channel number, it is possible to notify the teletext receiving section that the channel has changed.

Embodiment Hereinafter, a television receiver according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a television receiver according to the present invention.
