DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a scanning method and an electronic device related to a multimedia method and an electronic device for use in a television. Frequently added channel information. [Prior Art] Fig. 1 is a flow chart showing the steps of the embodiment of the present invention. 1] The conventional full-frequency scanning method is reset (Reset)_ (step sii) at the time of initialization, for example, the channel in the memory of the TV is channeled by the channel Llst, and then calculated Each candidate channel position ( , tooth, = 7 or offset (Ο -. The next position can be easily calculated by confirming the first position to determine whether there is a valid channel at the = position. If The lower-position is not stored. Next, it is judged whether; lock; or the offset is calculated to calculate the frequency of the lower-bit _3), and the system determines whether the currently calculated channel contains the frequency. 1 valley. The right channel cannot be locked', then return to step S12 to obtain the next frequency position to continue scanning. When locked, the video signal corresponding to the channel is captured (step 2 - upper '=: television signal (step S15) And, in the channel list of the channel of the channel (step S16). Next, whether the scan is completed (step S17). If yes, all 〇 758 >A32437TWF; MTKl - 〇 6-272; Alexchen c 200808052 Double forced [Step S18) operation. When the TV receiver moves over and provides for use Effective channel list. ±Re-man-per-channel scanning, to be moved, the effective channel is still combined, even if the TV receiver is not riding (morning or evening). ^ Channel is only in the receiver and TV There are daily talks between the broadcasters, the TV connection changes, the special environment of the Gan Ridan/鄕千, the transmission path, and the fact that the transmission path is tested at the peak time, it is impossible to receive certain channels. Therefore, the TV' Therefore, the receiver is updated, so that the user can watch all the channels that have the channel table dimension ^ 为 为 寺 寺 寺 多媒体 多媒体 多媒体 多媒体 多媒体 多媒体 多媒体 多媒体 多媒体 多媒体 早 早 早 早 早 , , , , , , , , [Invention] h Based on the above object, the embodiment of the present invention discloses a method for supplementing two members stored in an electronic device: : Table 'The electronic device is used to receive and process the frequency One of the members of the channel ## (Ch fine eISubset) in the ^ position body program, bribery, storage 隹 ... Μ Μ channel played by the media ° " 涌 k子木系 expressed as the channel table. The method includes = member: subset and department Partlally Scanning, and it is judged whether there is at least a candidate channel position during which the program content is not previously found. ^ 〇 758 — A32437TWF; MTKI.272; alexchen 6 200808052. Yes, the candidate channel position not previously found is added to the channel to update the channel list. The embodiment of the invention further discloses an electronic device for supplementing channel information, which is used for receiving and processing. - a series of candidate channel locations, the _frequency_concentrated channel played by the multimedia program, and the channel sub-category is the frequency table. The electronic device includes a tuning body; =!: the classifier is configured to receive the channel bit 3# for storing the channel table. The processor is configured to: skip the channel subset and partially scan the candidate channels 1 'm during the partial scanning step whether there is at least a previously selected channel location of the program content And, if so, the candidate channel and the channel list that were not found by Xianli. 1Add to the channel list to update [Embodiment] • The following 2 I let: The purpose, characteristics, and advantages of ί明 can be more obvious and easy to understand. The present invention is a technical feature of different embodiments of the present invention, and the configuration of the actual components is to explain the partial repetition of the reference numerals in the examples of the H#/, the middle example: 'And refers to the correlation between different embodiments. ..., f0 17 brothers' is not intended to disclose a second embodiment of the present invention. 9 Supplementary Channel - Method and Apparatus for BT 758-A32437TWF; MTKl-06.272; alexchen 7 200808052 • In a preferred embodiment, a television receiver receives and processes a channel in a subset of a subset of candidate channel locations Play TV shows. Figure 2A is a schematic diagram showing a full frequency scan showing a series of candidate channel positions. Each node between nodes 202 and 204 represents a frequency location corresponding to the channel of the playable program. In real-life applications, not every channel plays a TV show at every moment: When the user turns on the television receiver, the television receiver performs a full frequency scan on a series of candidate channel locations, as shown in Figure 1. Figure 2B shows the intent of the scan results of the full-frequency scan. Nodes 202, 203, 204, 205, 206 form a channel list, and each node carries valid program content that can be played, and the television player stores the channel list. Most TV receivers are equipped with only one tuner, which takes a lot of time on full-frequency scanning. If the effective channel changes, it is very inefficient to perform a full-frequency scan each time. However, if the full-frequency scan is not performed, the channel list cannot be continuously updated, and all valid I channels cannot be provided for the user to select. Thus, in a preferred embodiment, in addition to full frequency scanning, the television receiver performs a partial scan. In a partial scan, the television processor skips the candidate channel locations of the existing active channels based on the channel list, and only scans channels that are not found and can play valid program content. Figure 2C shows a schematic diagram of a partial scan that bypasses nodes 202, 203, 204, 205, 206. After performing a partial scan, the nodes 207, 208 are locations that have not previously been found and can play valid program content, adding the channels of the corresponding nodes 207, 208 to update the channel list, as shown in Figure 2D. 0758-A32437TWF; MTKI-06-272; alexchen 8 200808052 In order to make the operation of the pen-based receiver more suitable for different needs, it can provide relevant settings to determine when to perform full-frequency scanning and when to execute part of the knowledge of the field And this setting can be changed according to user needs. For example, a remote control can be used to change the scan time. The setting and channel table can be stored in different types of memory according to different requirements of the tablet, such as 'Dynamic Random Access Memory ' DRAM, Synchronous Dynamic Random Access Memory , SDRAM), Double Data Rate Random Access Memory (DDR RAM), Flash Memory, Electronically Erasable Programmable Read Only (Electrically Erasable Programmable Read Only) Memory, EEPROM), hard drive... and more. 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 channels are separated by a fixed distance, the fixed distance is added to the currently scanned 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 200808052 'Create - initial channel list and 餹 在 ^ : The initial channel list may not contain any channel information ":: two intentions, the content of the effective program content = The table skips the known candidate channel::: According to one of the tables t, the channel is required to be ##^^ is not in the channel, / is forced to scan the C step 骡S3I).
