  By the way, the channel preset time during which the channel preset function operates varies depending on the specifications of the television receiver, the number of broadcast channels, and the like.

  For example, in the case of a television receiver of the US specification, analog broadcasting and digital broadcasting of ATSC (Advanced Television Systems Committee) system are implemented in the United States, and these broadcasts have different frequency allocation patterns depending on the regions. STD (Standard Futures) , IRC (Incremental Related Carriers), or HRC (Harmonic Related Carriers), the channel selection frequency range is wide, the number of broadcast channels is large, and it is necessary to specify the frequency allocation pattern. And channel presets take a lot of time.

  In addition, even in the case of domestic television receivers in Japan, if you want to store preset channels for analog broadcasting, terrestrial broadcasting, and digital broadcasting for satellite broadcasting without omission, the channel selection frequency range is wide, and the number of preset recording channels is also large. Because it increases, it takes time. Furthermore, in the case of television receivers with specifications (world specifications) used in many countries and regions, a wide range of tuning frequency ranges are swept and scanned with a large number of broadcasting systems such as NTSC, PAL, SECAM, etc. It will take a long time to perform channel presets for broadcasts.

Is displayed.

  By the way, the progress status graph is specifically a bar graph α in the horizontal direction at the bottom of the screen displayed on the display screens Pc and Pd of the screen display device 5 in FIG. 4 and FIG. The colored portion extends from the left end to the right end as the reception frequency of the tuner portion 2A increases within the channel selection frequency range. At this time, the bar graph α changes in proportion to the reception frequency, and a dark cursor β that can be moved by the operation of the remote control transmitter 1b is displayed at the tip thereof, and the current reception frequency is displayed in the vicinity of the bar graph α. The progress of the channel preset corresponding to is displayed in%.

  The reception presence / absence detection means is means for detecting presence / absence of reception of the broadcast of the tuner unit 2A during the channel preset. Specifically, the reception tuner during operation of the tuner unit 2A broadcasts according to the change of the reception frequency of the channel preset. Whenever reception demodulation is performed, the presence / absence of broadcast reception of the tuner unit 2A is detected from the presence / absence of broadcast notification notified from the tuner unit 2A to the channel selection control unit 10 via the main control unit 8.

  The broadcast mark display processing means is means for forming a display output of the broadcast mark to be displayed at the position of the corresponding reception frequency of the progress graph, for example, the bar graph α based on the detection of reception by the reception presence / absence detection means. Specifically, an OSD display output for displaying the narrow cursor-shaped broadcast mark γ shown in FIGS. 4 and 5 at the reception position of each broadcast is formed. The broadcast mark γ is different from the bar graph α in color or gradation so that it is more prominent than the bar graph α. When there are a plurality of broadcasts at the same reception frequency, only one broadcast mark γ is displayed as a representative mark.

  The broadcast guidance display processing means uses the channel selection information preset stored in the memory 14 corresponding to the reception frequency of the broadcast mark γ selected by the user from the display screens Pc and Pd of the screen display device 5 during channel presetting. Based on, for example, the broadcast guide δ of FIG. 5 including at least the channel number of the broadcast existing at the reception frequency is formed, and a small window-like OSD display output of the broadcast guide δ is formed in the vicinity of the selected broadcast mark γ. This OSD display output is supplied to the screen display device 5 via the signal synthesizer 4 and displayed on the screen. As is clear from FIG. 5, the broadcast guidance δ of the present embodiment scrolls up and down a row of information for each broadcasting station in which, for example, channel numbers and broadcasting station names are arranged in a row in a small window like a so-called balloon. When the user selects a channel number or broadcast station name in each column displayed on the screen by operating the remote control transmitter 1b, the channel selection control means is selected when the channel preset is completed. The channel selection information of the broadcast is read from the memory 14, and the tuner unit 2A is set to the channel selection state of the selected broadcast.

A small window is displayed near the broadcast mark γ, and when the selection is stopped, the process proceeds from step S6 to step S8, and the display of the broadcast guidance δ is terminated.

  When the broadcast mark γ is selected and a desired broadcast channel number or the like of the broadcast guide δ displayed on the screen is selected, the process proceeds from step S7 to step S10 through step S9, and the selection information is displayed in the broadcast guide. The processing means stores and holds it. Each time the selection of the channel number or the like is repeated, the broadcast guidance display processing means updates the stored content and stores and holds the latest selected content.

  Then, by the loop processing returning from step S11 to step S12 through step S12, the bar graph α as the progress graph gradually becomes longer during the channel preset, and the channel preset state is easily understood depending on the length. The face is displayed.

  Also, on the bar graph α, the position of the reception frequency of the broadcast preset stored so far is displayed as a broadcast mark γ, and the presence of the preset stored broadcast in the tuning frequency range of the tuner unit 2A is visually confirmed. Displayed in an easy-to-understand manner.

  Further, when the user selects the broadcast mark γ on the display screen, a small window-shaped broadcast guide δ is displayed in the vicinity of the broadcast mark γ. Channel numbers of receivable broadcasts that can be stored can be easily grasped, and each broadcast channel is displayed in a small window display of the broadcast guide δ for a plurality of receivable broadcasts existing at the same reception frequency. Numbers etc. are displayed and can be easily grasped.

  Even when there are a large number of broadcasts, the user can easily know from the broadcast marks γ on the bar graph α that their presence and presets have been stored. By making a selection, a small window of a broadcast guide δ balloon is displayed on the screen, and the preset channel number of each broadcast can be known from this display.

  Therefore, there are many broadcasts that can be channel preset because of the simple and inexpensive software processing configuration with a small number of parts that display the bar graph α, broadcast mark γ and broadcast guide δ on the screen during channel preset. Even when it takes time, the user can easily know the state (situation) of the channel preset that changes from moment to moment during the channel preset, and the user's discomfort, anxiety and boredom are eliminated and satisfaction is given. be able to.

  In addition, since the bar graph α, the broadcast mark γ, and the broadcast guide δ are easily displayed on a predetermined background image of the blue background during the channel preset, the display performance in the channel preset state is improved.

  When the channel preset is completed, the process proceeds from step S11 to step S13 in FIG. 2, and the OSD display output such as the bar graph α, the broadcast mark γ, and the broadcast guidance δ is turned off, and the received image display output of the tuner unit 2A Is supplied from the video processing unit 3 to the screen display device 5 to return to the normal reception display state.

  At this time, if the broadcast information selected by the broadcast guidance display processing means is stored and held, the process proceeds from step S13 to step S15 via step S14, and the tuning control unit 10 causes the tuner unit 2A to The channel selection state of the broadcast selected during the channel preset is set, and the channel preset processing is completed in this state. If the broadcast is not selected during the channel preset, the process proceeds from step S13 to step S16 via step S14, and the tuner 2A selects the preset channel condition of the preset condition stored, for example, the highest reception frequency. Is set to the channel selection state of the low broadcast, and the channel preset is completed.

  Therefore, when the user selects a desired broadcast from the broadcast guide displayed on the screen during the channel preset, the tuner unit 2A is automatically set to the selected channel selection state when the channel preset is completed, and the user There is no need to wait for the end of the channel preset to perform the channel selection operation, which greatly improves convenience.

  In the present embodiment, the channel preset processing unit 12 of FIG. 1 further includes broadcast state notification processing means for changing the display color of the broadcast guidance δ according to the broadcast state such as the type of broadcast and the reception level.

  By the way, the broadcast state may be one or more of a plurality of states such as a broadcast type and a reception level. When one state is notified, the number of the channel number of each broadcast in the broadcast guide δ, the broadcast When the color of all or part of the station name characters (for example, only numbers) changes in any one state such as the type of broadcast, reception level, etc., and broadcasts a plurality of states, for example, each broadcast in the broadcast guide δ The color of each part to which the numbers of channel numbers, the characters of the broadcast station name, etc. are assigned for each state changes in accordance with each state such as the type of broadcast and the reception level. The color change includes a pattern change and blinking.

  For example, the color change setting is performed by displaying the menu screen Pb * of FIG. 8 instead of the menu screen Pb of FIG. 3B, selecting the display color setting c of the menu screen Pb *, In the display color setting field d, for example, a change in display color according to the broadcast state such as the type of broadcast and the reception level is set, and this setting is performed by the broadcast state notification processing means being stored and held.

  Next, the operation of the channel preset process based on the above settings will be described with reference to FIGS.

  In the flowchart of the overall processing of steps Q1 to Q17 in FIG. 6, steps Q1 to Q16 are processing steps similar to steps S1 to S16 in FIG. 2, and the difference is that step of display color changing processing is subsequent to step Q7. This is the point where Q17 is added.

  Then, the display color changing process of step Q17 comprises, for example, the processes of steps Q171 to Q176 of FIG. 7. If the broadcast state notification processing means stores and holds the display color change setting, the step of FIG. When the broadcast guidance δ is displayed in Q7 and the process proceeds to step Q17, the process proceeds from step Q171 in FIG. 7 to step Q172, and the object whose display color is changed is recognized in steps Q172 and Q173. With Q174 and Q175, for example, the channel number of each broadcast of the broadcast guide δ and the color of part or all of the broadcast station name are changed according to the type of broadcast and the reception level. If the broadcast state notification processing means does not store and hold the display color change setting, the process proceeds from step Q171 to step Q176, and the display color of the broadcast guidance δ is not changed.

  Therefore, in the case of this embodiment, the broadcast channel number of the broadcast guide δ displayed on the screen during the channel preset, the broadcast station name, etc. are broadcast such as analog broadcast, digital broadcast type, reception level, etc. Depending on the state, the user can obtain more detailed information on the channel preset state from the display color, and the display performance of the channel preset state is further improved.

When a broadcast is selected from the broadcast guide δ during channel presetting, the selected broadcast display processing means operates, and at step W181, Instead of the reception tuner 2a (or 2b) whose reception frequency is variable in the channel preset of the tuner unit 2B, the vacant reception tuner 2b (or 2a) is controlled to receive the selected broadcast.

  Further, the process proceeds from step W181 to step W182, and it is determined whether the sub-screen display or the split-screen display is set.

  If the sub-screen display is set, the process proceeds from step W182 to step W183, and the reception image of the broadcast being received by the empty reception tuner 2b is compressed into a small screen of a predetermined size. The display output of the small screen of the received image formed by the processing unit 3 is superimposed and combined with the OSD display output that displays the bar graph α etc. on the blue background, and based on the combined output, the screen display device 5 performs channel presetting. For example, the screen Pe in FIG. 12 is displayed.

  Further, if the split screen display is set, the process proceeds from step W182 to step W184, and the split reception screen of the small screen is obtained by compressing the received image of the broadcast being received by the empty reception tuner 2b to, for example, ½. At the same time, the OSD display output screen that displays the bar graph α, etc. on the blue background is also compressed by half, and the screen display outputs of both screens are added and combined, and the channel preset is based on the combined output. For example, the screen Pf of FIG. 13 is displayed on the screen display device 5.

  Therefore, in the case of the present embodiment, during channel presetting, a broadcast selected by the user from the broadcast guide δ displayed on the screen display device 5 is received, and the received image is displayed on the display screen. In addition, the user can select and enjoy a desired broadcast, and convenience and the like are further improved.

  The present invention is not limited to the above-described embodiments, and various modifications other than those described above can be made without departing from the spirit thereof. For example, control of the channel preset processing unit 12 can be performed. It goes without saying that the processing procedure and the like may be different from those of the above embodiments.

  Further, the progress graph is not limited to the bar graph α, and may be various graphs such as a circular graph in which the fan area increases as the channel preset progresses.

  Further, the shape of the cursor β, the broadcast mark γ, the broadcast guide δ, etc. may be any. The display color of the broadcast guide δ includes, for example, the channel number, the display color of the broadcast station name, the type of broadcast, and the reception You may make it vary according to each level.
