Open/read Figure 3 and Figure 4··• First, when the controller After the boot signal of the system 3 (not shown, the step is to build a program list, that is, a built-in program list is copied to facilitate the item selection step 402). In the non-supplement memory 36 (when the controller 37 receives, for example, use Steps are thorough, that is, after turning on the (4) device 3〇 channel scanning request (harmonic device as an example, the first error corrector) enters two: any: In this embodiment, an update program list is formed by updating the scanning program (hereinafter, and later entering a channel scanning period (step 1283539 404) to update the built-in program table content to form an updated program list. Finally, After the channel scanning process is completed, the updated program list is saved back to the non-swing "(.. in the hidden body to replace the built-in program list (step 4〇5). Thus, when receiving the next-playing TV request) The user uses the update section and plays the television program corresponding to the content of the updated program list. - The specific implementation of the channel scanning program in the above step 404 is as shown in the figure: "No", the first item is stored in the non- The built-in program list in the volatile memory 36 is stored in the temporary memory, for example, the read memory 35 (RAM). Then the control _% starts to sweep the training. When the program is programmed, it will be scanned to the program and the corresponding frequency (all programs in the first two-point table and their frequencies are compared (step 5〇2). Judgment: ^ in the table of contents, in the corresponding program There is a program near the frequency (step 5〇3), if any The words are treated as the same section and their phase-to-point frequency value is changed to sweep to the program value (step 504). Conversely, the 芒力兮卢石丨μ贝车车 β " $in the heart of the corresponding fresh nearby frequency ^No Langmu, then it is swept to the program as a new program, and the new program f corresponding solution is added to the domain program table ((4) 5G5). Then the content of the new built-in program table is the modified program and corresponding Channel content, (4) into-update program list (step 5G6). Finally, in step to judge whether the description is completed, ^ no, then continue to repeat the above-mentioned steps of the action flow, until the judgment of the woman is finished, enter the steps of Figure 4: One of the user inputs plays a TV request (step ^ exists in the non-volatile memory 36), and then another 1283539 tuner 31 (second tuner) controls the $^^ channel to Receiving a selected frequency, TV nickname, via the corresponding decoder, after the output office (four), the money code signal is the most visible on the TV (step 4〇7). The present invention further automates the function of the desk and the play sweep progress. As shown in FIG. 4, the disk τ receives two hearts and ... updates the program channel of the program table - one week or one month, 1 - the predetermined time (for example, f ~ solid moon), turns on the tuner 30 to perform step 404 The frequency = 'field order' to update the contents of its updated program list (step 408). In addition, Y allows the user to simultaneously know the progress of the current sweeping while watching the television. When the channel is swept, the controller 37 can simultaneously display a graphical interface for displaying the current user on the display 34. (Step 409), so that the user can know the current channel scanning progress. The present invention provides a television program channel sweeping method, which can enable the electric system to perform a television broadcast function during the scanning channel. It can be understood that the channel scanning program can not play the electric power when the channel scanning program is performed. It is not only time-consuming and inefficient, but it takes time to scan the channel for a few minutes.
