[Technical field to which the invention belongs]

 The present invention relates to a television broadcast receiver for receiving both digital television broadcasts and analog television broadcasts by terrestrial broadcasting, and more specifically, comprises two sets of up-down keys, and one of the up-down keys is operated. The present invention relates to a television broadcast receiving apparatus for receiving digital television broadcasts.

[0002]

[Prior art]

 In terrestrial television broadcasting, digital television broadcasting (hereinafter simply referred to as digital broadcasting) and analog television broadcasting (hereinafter simply referred to as analog broadcasting) use the same frequency band. ing. For this reason, a television broadcast receiving apparatus capable of receiving both digital broadcasts and analog broadcasts has a configuration in which a numeric key for directly specifying a channel number and a set of up / down keys are provided for channel selection. Has been adopted. The following method has been proposed for changing the channel when the up / down key is operated.

[0003] That is, two modes are provided: a mode for receiving digital broadcasting and a mode for receiving analog broadcasting. This mode can be switched. When the up / down key is operated in a state in which the digital broadcast receiving mode is set, the channel is changed from a receivable digital broadcast channel from a smaller channel number to a larger channel number, or The channel number changes from higher to lower. Also, when the up / down key is operated in the mode set to receive analog broadcasting, among the channels of analog broadcasting that can be received, from the smaller channel number to the larger channel number, or to the larger channel number. From the side to the smaller side (referred to as a first prior art).

Further, in the prior art proposed as Japanese Patent Application Laid-Open No. H11-205697, the following configuration is disclosed. That is, it is assumed that each of channels 1, 2, and 3 of the channel number is an analog broadcast, and 1, 3, and 5 are set as the position numbers. It is also assumed that channel numbers 4 and 5 are digital broadcasts, and position numbers 2 and 4 are set. It is also assumed that three services are multiplexed on the channel of position number 2 (channel of channel number 4), and the logical numbers of the services are 1, 2, and 3. Assume that the receivable channels are as described above, the position number currently being received is 1, and analog broadcast of channel number 1 is being received.

In this state, when the up key is operated, the service of the logical number 1 of the channel of the position number 2 (channel number 4) is received. In the following, in response to the operation of the up key, reception of the service of logical number 2 of position number 2 (channel number 4) and reception of the service of logical number 3 of position number 2 (channel number 4) change. When the up key is further operated, an analog broadcast of position number 3 (channel number 2) is received. In this state, when the down key is operated, the received channel or service changes in the opposite direction to the above order. That is, when the up / down key is operated, the analog broadcast and the digital broadcast are changed based on the position number and the logical number of the service without being distinguished from each other (referred to as a second conventional technique).

In the technique proposed in Japanese Patent Application Laid-Open No. H11-164214, the channel is changed by the following method. That is, 1 to 99 are assigned to terrestrial channel numbers, and 100 to 999 are assigned to channel numbers of digital satellite television broadcasting. When the up key is operated, of the receivable channels, the channel is continuously changed from a channel having a small numerical value to a channel having a large numerical value. Therefore, if the up key is operated while the largest channel among the receivable terrestrial waves is being received, then the smallest channel among the receivable digital satellite television broadcasts is received. Also, when the down key is operated, the receivable channels are changed continuously from the channel with the higher numerical value to the channel with the lower numerical value. Therefore, if the down key is operated while the smallest channel among the receivable digital satellite television broadcasts is being received, then the largest channel among the receivable terrestrial waves will be received. (Third conventional technique).

[0007]

[Problems to be solved by the invention]

In other words, when switching from the reception state of digital broadcasting to the reception of analog broadcasting, or from the reception state of analog broadcasting to reception of digital broadcasting, first perform the mode switching operation and then operate the up / down key. There is a need. For this reason, the key operation was troublesome.

When the second conventional technique is used, the following problem occurs. That is, when digital broadcasting and analog broadcasting are mixed, the number of digital broadcasting channels may be smaller than the number of analog broadcasting channels in some regions. In such an area, when operating an up-down key to receive a digital broadcast, the number of times the key is pressed often increases, and the key operation becomes cumbersome.

[0009] The third conventional technique is a technique in a case where all channel numbers assigned to analog broadcasting are smaller than all channel numbers assigned to digital broadcasting. For this reason, it has been difficult to apply digital terrestrial broadcasting to analog broadcasting in which it is difficult to distinguish between digital and analog broadcasting depending on the channel number.

[0010] The present invention has been made to solve the above-mentioned problem. The purpose of the present invention is to provide a first up-down key for selecting only digital television broadcasting and a second up-down key.
