The channel position is usually selected during the setting (step S12). The candidate channel bit f is fixed distance or offset (Offset). After the first channel of the handle, it is easy to calculate the lower-position to determine if there is a valid channel at the location. If the ; , then & add a certain distance or offset to calculate the next bit. Receiver, to determine whether it is possible to lock the switch and move C 1 . U and I work differently. If the frequency is used to confirm whether the currently calculated channel includes the channel position to continue to lock, then return to step si2, and obtain the next step C1 can be locked 掏' then capture the corresponding TV signal of the channel (step 2 (4), analyze the television signal (Step si5), and the upper channel tribute is stored in the ticker, and the judgment channel is completed ==) (step _. Then 'field ^ step sn). If yes, all 〇 758-A32437TWF; MTKI-06-272; alexchen 5 1335179 • channel (step S18) are displayed, otherwise. Step 511 performs another-full-frequency scan. • When the TV receiver has moved over, then the user provides a valid channel list. There are 8=: the person performs the channel scan to be moved, and the effective channel still reads 'even if the TV receiver is not connected to the TV broadcaster--the TV connection changes, and the special environment that affects the TV reception may be present. Due to the load of the transmission path at the peak time. After testing, it was unable to receive certain channels. Therefore, the TV receiver is updated so that the user can view all valid channels. The human dimension thus allows the invention to be used for digital television reception: a method that scans for lost or undiscovered channels, while the media electronic device does not scan for channels that are already in the negative path. SUMMARY OF THE INVENTION Based on the above objects, an embodiment of the present invention discloses a method for supplementing and storing in a electronic device == Channel Subset towel for receiving and processing a series of candidate channel positions. Frequency: Langmu' The subset of channels is represented as the channel list.

'To the candidate, the location is added to the channel list to update [Embodiment] The purpose, features, and advantages of the following are more obvious. Understand, give a good example; and cooperate with the attached figure 2nd to 4th, this;; the month of the brothers. The present specification provides different examples to illustrate the technique of =W Μ(4) In the embodiment, the examples are not intended to limit the present invention, and the parts of the real h and f are repeated, for the sake of simplicity of explanation, and are not intended to capture different households and examples. (4) (4) - A method and electronic device for supplementing channel information. 〇 758-A32437TWF; MTKI-06-272; alexchen 7 Queue (4) C-wide case '-TV receiver receiving and processing - 曰 曰' = ',, stand it - the TV played by the channel in the channel subset~ Figure 2A shows a schematic diagram of full-frequency scanning, which shows = frequency position. Each node between nodes 2〇2 and 204: Table 2: Frequency position of the channel where TV programs should be placed: Channel name skin +,, 丨 does not use the user to turn on the TV receiver == program. When it is selected, the channel position is selected - full-frequency scanning, the flow of the series of 1 2B map shows the full frequency selection No. 2〇3, 2〇4, 205, 2〇6 不 不 图 ° node 2 〇 2, the effective program content played, the table 'and each node can carry most of the eight TV players to store the channel table The multi-time gate/in-view receiver is only equipped with a tuner. The A-cost sweep is very good. The master scan does not continuously update w, and does not perform full-frequency. The way for the user to choose. ❼ can not provide all the valid, therefore, in the preferred embodiment, the scan is not found and can play the effective channel m position 'is found and can play the effective program content 3 207, 208 For the channel that has not previously been 2〇8, the corresponding node 207,衣758-A32437TWF; MTKl-〇6.272; alexchen 〇1335179 ·· In order to make the operation of the TV receiver more suitable for different needs, the relevant settings can be provided to determine when to perform full-frequency scanning. And when to perform partial scans' and the settings can be changed according to user needs. For example, a remote control can be used to change the scan time. The settings and channel tables can be stored in different types of memory according to different design requirements. , example * 1 such as ': Dynami: c Random Access Memory (DRAM), Synchronous Dynamic Random Access Memory (SDRAM), double data Φ transmission random access memory (Double Data Rate Random Access Memory (DDR RAM), Flash Memory, Electronically Erasable Programmable Read Only Memory (EEPROM), Hard Disk, etc. Similarly, the setting can be designed with a different data structure than the channel table. For example, the channel list can be implemented by a Link List, an Array, or an Index Table. If two adjacent frequency ® channels are separated by a fixed distance, the fixed distance is added to the current scanning position to calculate the next scanning position. In addition to the television receiver design, another preferred embodiment applies the partial scan to a Radio Receiver to effectively maintain the channel list. For example, Digital Radio Broadcasting also has a series of channels, and not every channel plays television programs at every moment. Figure 3 is a flow chart showing the steps of the method of supplementing channel information in the embodiment of the present invention. 0758-A32437TWF; MTKI-06-272; alexchen 9 The initial t channel filament exists in iM, which means that the active section == signal. _ 道表系 Channel table skips the known candidate frequency, position ^ position. Then, according to this, one of the channels of Table 1f7 is directed to force, ', and set, and select not to be in the channel, and the location is known (step $31). Next, the selected frequency s S32)' is determined. That is, whether or not the effective section 2 is fixed (the step cannot be locked, then it is returned to the right of the right side, and the selected channel position is below the channel table. According to the channel table selection, the frequency is not locked, and the reference is made. The selected channel position can be taken to the TV signal corresponding to the channel (the gassing video number (step S34), and the channel is ~, in the memory to update the channel table (step S35). Then 1 is broken ^ scanned End all candidate channel positions (step _.:4 = display the ancient phase in the channel table, bitter γ ^ then S3 select m=fsj7 according to the channel table) 'Others return to the step to scan. & FIG. 4 is a schematic diagram showing the structure of the device for supplementing channel information according to the embodiment of the present invention. The electronic device is a TV or set-top box (STB) supporting partial scanning. • The electronic device 400 includes a spectrometer 41〇, a controller 42 (which may be the processor of the television device 400), a memory 43A, a Parser 440, a decoder 45 and a display device 46.
