Benefits of technology

[0012]According to an embodiment, the invention allows the user to watch rapidly a desired program, and offers an effect of relieving a stress on the user in the channel selecting operation.

Problems solved by technology

Also, the reach of the wave is also restricted.
When the user successively selects the physical channels containing many useless channels in a dispersed fashion by the increment / decrement buttons, the user must perform wasteful operations.
Further, the channel allocation is not performed uniformly in all the districts, and depends on the district.

first embodiment

[0066]FIG. 1 shows a structure of a broadcast receiving device of a first embodiment.

[0067]Referring to FIG. 1, a broadcast receiving device 100 includes an antenna 20, a tuner 22, a video and audio data extracting unit 24, a program selecting unit 10, a remote control 32 and a television set 26. Program selecting unit 10 has a photo-receiver 34, a channel search unit 11, a channel map storage unit 14, a channel order setting unit 12, a channel switching unit 13 and a program guide display unit 15.

[0068]A remote control 32 and a photo-receiver 34 receiving a signal from remote control 32 form an operation input unit 34 accepting a user's operation for selecting a channel.

[0069]FIG. 2 shows buttons of a remote control.

[0070]Referring to FIG. 2, a power button 33 is employed for turning on / off a power of the broadcast receiving device. Channel number buttons 36 are employed for selecting channels of numbers (virtual channel numbers in this example) on the respective buttons. An increm...

second embodiment

[0111]In the second embodiment, channel order setting unit 12 changes the selection order of the selectable channels in the channel map according to an instruction provided from the user through operation input unit 34.

[0112](Specific Examples of the Channel Map, Selection Order and Electronic Program Guide after the Setting of the Channel Order)

[0113]FIG. 11 shows an example of the changed channel map employed when the user provides an instruction for changing the channel selection order.

[0114]FIG. 12 shows an order in which the channel selection moves when the channel map of FIG. 11 is used and the user depresses the increment / decrement buttons.

[0115]When the user operates the buttons (not shown) on remote control 32 to change the channel selection order such that the selection moves to the channel “8” after selecting the channel “5”, and moves to the channel “7” after selecting the channel “8-3”, channel order setting unit 12 rewrites the channel map as shown in FIG. 11.

[0116]Thu...

third embodiment

[0125]In a third embodiment, channel order setting unit 12 disables the selection of a part of the channels in the channel map and changes the selection order of the selectable channels in accordance with the instruction provided from the user via operation input unit 34.

[0126](Specific Examples of the Channel Map, Selection Order and Electronic Program Guide after the Setting of the Channel Order)

[0127]FIG. 15 shows an example of the changed channel map employed when the user provides the instruction for disabling the selection of a part of the channels and changing the channel selection order.

[0128]FIG. 16 shows an order in which the channel selection moves when the channel map of FIG. 15 is used and the user depresses the increment / decrement buttons.

[0129]When the user operates the buttons (not shown) on remote control 32 to disable the selection of channels “8”, “8-1”, “8-2” and “8-3”, and to change the channel selection order such that the channel selection moves to the channel...

Abstract

A tuner receives broadcast data on specified channels. A channel search unit controls the tuner to search for available channels, and creates a channel map representing the available channels and a selection order thereof. A channel order setting unit changes setting about enabling / disabling of the selection and / or the selection order of the channels in the channel map. An operation input unit accepts a channel selecting operation of a user. When the user performs an operation for channel forward selection or channel reverse selection through the operation input unit, a channel switching unit changes the selection of the channel according to the channel map and causes the tuner to receive the broadcast data on the selected channel.

Description

TECHNICAL FIELD[0001]The present invention relates to a broadcast receiving device and a program selecting method, and particularly to a broadcast receiving device and a program selecting method that select programs by operating forward / reverse selection operations or using an electronic program guide.BACKGROUND ART[0002]In television broadcast, available frequency bands of carrier waves and available channel numbers are determined according to public rules, independently of kinds of analog and digital. These are referred to as “physical channels”. In Japan, VHF (Very-High Frequency) and UHF (Ultra-High Frequency) bands are assigned to the ordinary analog broadcast, and the UHF band is assigned to the digital terrestrial broadcast. As the digital broadcast has started, program contents that are substantially the same as those provided by the conventional analog broadcast have also been provided on the digital channel. However, the assigned physical channel number of the digital broa...
