[Prior Art] TV programs are the main source of image information for many people in their daily lives. 'People can learn about weather profiles, news, or general entertainment information.' With the rapid development of video and audio information, the number of TV channels has increased. However, in a TV channel filled with a wide variety of information, 'not every channel is suitable for every user. Therefore, during viewing, the average user will first perform a channel search to select the channel to be viewed. However, after a period of time, if the user is tired of the content of the channel, the search may need to be repeated again. In the case of a large number of channels, the search is quite time consuming. In order to solve the above problems, some related products will provide a full channel preview function, and simultaneously display the programs played by multiple TV channels in the preview screen, that is, take the rotation to switch all the channels, and sequentially provide a preview of each channel of the user. The screen 'Because the need to scan the cat from each channel - the page screen provides a user preview, resulting in a long time from the user to perform the preview function to switch to the desired video channel' (4) is inconvenient to use. "Other aspects, 5, the user will play TV on the current video channel to switch to another channel' but because I don't know the original video = wide::: end, so I am not sure when to switch back to the original viewing l '疋 watching When watching a channel, you cannot watch another 6 1339067 to know the current status of the channel. Therefore, a channel preview method is needed to improve the above problem. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a channel preview method and a device for implementing the channel preview method, which can distinguish a plurality of preview channels from all provided television channels according to user viewing habits, and provide a user to view one. When the main channel program is displayed, the program playback dynamics of several preview channels are simultaneously browsed, and the convenience of quickly switching to one of the preview channels is facilitated. According to the above object of the present invention, a channel preview method is proposed. According to a preferred embodiment of the present invention, the channel preview method comprises the steps of: determining a preview mode, sorting the television channels according to the preview mode, and determining a preview channel based on the results of the sorting. Among them, the channel preview method provides three preview modes, a cumulative weekly viewing mode, a moving average fixed number of viewing modes, and a user-selectable mode. When the preview mode is set to the cumulative weekly viewing mode, the steps of sorting the television channels include: determining the day of the week as the day of the week, accumulating the viewing time of each channel on the user's day, and sequentially arranging the television channels according to the length of the viewing time. . When the preview mode is the moving average fixed day viewing mode, the steps of sorting the TV channels include: recording the user's viewing time on each channel, calculating the cumulative viewing time of each channel in the fixed number of turns, and calculating the length of the channel according to the cumulative viewing time. Arrange in order. When the preview mode is the user's self-selection mode, the steps of sorting the TV channels include: reading in and storing the preview channel input by the user. The present invention also discloses an apparatus for implementing the channel preview method. The apparatus includes a first tuner, a second tuner, a first video decoder, a second video decoder, and a video processor. The first modulator receives the first broadcast signal 'generating the first video signal, and the second tuner receives the second broadcast signal to generate the second video signal. The first video decoder receives the first video signal and decodes the first digital video signal, and the second video decoder receives the second video signal and decodes the second digital video signal. The video processor receives the first digital video signal and the second digital video signal' and transmits the video to the display via the video interface. The 'video processor includes a first deinterlacing module, a second deinterlacing module, and a Picture-Over-Picture module. The first deinterlacing module receives the first digital video signal to generate a first non-interlaced signal, the second deinterlacing module receives the second digital video signal to generate a second non-interlaced signal, and the multi-picture display module receives the first non-interlaced signal. The signal and the second non-interlaced signal are generated to generate a main channel picture and a plurality of preview channel pictures for display. The device scans the main channel picture with the first modulator, and uses the second to scan the preview channel picture and combines the multi-picture display technology into a main channel picture and a plurality of preview channel pictures. By applying the invention, according to the user's viewing habit, a plurality of preview channels 'providing the user to watch a program of a main channel' can be browsed simultaneously from the provided television channels, and the program playing dynamics of several preview channels can be browsed at the same time, and the program can be quickly switched to One of the preview channels is convenient. [Embodiment] Referring to FIG. 1 and FIG. 1 , a diagram of a channel preview method according to a preferred embodiment of the present invention is shown. A flowchart of a preview mode that does not follow a preferred embodiment of the present invention is depicted. The channel preview method includes a step U0, a decision preview mode, a step 12G, sorting the television channels according to the preview mode, and a step 18, determining the preview channel based on the sorted result. This channel preview method provides three preview modes, as shown in Fig. 1B, the cumulative weekly viewing mode B0, the moving average fixed day viewing mode 140, and the user-selected mode 15(). These preview modes can sort all available TV channels according to the user's past viewing habits or set the user to set several preview channels. Wherein, when the preview mode is set to the cumulative weekly viewing mode 13〇, the process of sorting the television channels includes: step 132, determining that the day is the day of the week, and step 134' cumulatively recording the viewing time of the user on each television channel on the day. And in step 136, the television channels are arranged in order according to the length of the viewing time. For example, users watch different programs every day during the week. Users may often watch "Channels", "Channel 2", "Channel 3" and "Channel 4" on a weekly basis. 6. Watching "Channel 55", "Channel 66", and "Channel 77", the cumulative weekly viewing mode 130 will judge the user to watch "Channel 1", "Channel 2", and "Monday" after Monday. The time of channel 3" and "channel 4" are recorded separately, and after judging that it is Saturday, the time for the user to watch "channel 55", "channel 66", and "channel 77" on Saturday is recorded separately. After a few weeks have elapsed, the cumulative weekly viewing mode 130 ranks all television channels according to the length of the cumulative viewing time, and determines that the first three channels with the longest cumulative viewing time on Monday are "Channel 1", "Channel 2", As well as "Channel 3", the preview screens of the three channels are displayed on the preview screen. The first three channels with the longest cumulative viewing time on Saturday are "Channel 55". "Channel 66" and "Channel 77", so 1339067 is displayed in the preview screen without preview screen of these three channels. Therefore, the preview channel displayed from Monday to Sunday will vary depending on the user's viewing habits during the week. When the preview mode is set to the moving average one fixed number of viewing modes 140, the process of sorting the television channels includes: step 142, recording the viewing time of the user in each of the television channels, step 144, calculating the fixed number of days. The cumulative viewing time of each television channel, and step 146, the television channels are arranged in order according to the length of the viewing time. For example, when the fixed number of turns is set to, for example, sixty days, the mode will be the user every day. The channels and time of the recording are recorded separately, and the cumulative viewing time of each television channel in the past 60 days is calculated. Then all the television channels are arranged according to the calculated length of the accumulated viewing time. Next, determine the first three channels with the longest cumulative viewing time in the past 60 days, and preview the three channels in the preview. When the preview mode is set to the user self-selection mode 150, the process of sorting the television channels includes: step 152, reading the preview channel input by the user' and step 154' storing the preview channel input by the user. Different from the above two modes' This mode provides users with the flexibility of specifying the channel, allowing the user to specify the preview channel according to their own needs. After reading and storing the preview channel input by the user, the preview channel is displayed in the preview. Please refer to FIG. 1C, which is a schematic diagram of a screen displayed on a screen according to a preferred embodiment of the present invention. This channel preview method uses multi-screen display technology to cut the display surface into one main channel and several preview channels. The main channel 191 is used to display the main channel screen selected by the user from all provided 10 1339067 TV channels via the selected ones.
