 1 is a flowchart of an implementation method for generating a customized channel list according to an embodiment of the present invention; FIG. 2 is a flowchart of an implementation method for reading a customized channel list according to an embodiment of the present invention; FIG. 3 is a customized channel according to an embodiment of the present invention; A functional diagram of the list. DETAILED DESCRIPTION OF THE INVENTION The core idea of the present invention is: formulating a file specification for a channel list of an existing mobile TV, using the file specification to format a channel information of an existing mobile TV, and newly creating a new one in the mobile terminal Customize the channel list file and save the converted channel information to the custom channel list file.

 The customized channel list file includes a service name, a program play time, a program name, a program classification, and a content introduction. Therefore, the user does not need to download all the SG data every time the mobile TV function is activated; and, the custom channel can also be used. The list file is shared with other terminals. The shared channel information contains most of the SG data, so that the terminal can download only the real-time data after loading the customized channel list file, and does not update the channel and the program content, thereby reducing the download amount and saving network resources.

 The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The indication includes the following steps:

 Step 101: Start the mobile TV function and download the SG data of the mobile TV service.

 Step 102: Select the channel list updated in the current SG data, select the channel in the channel list, and perform multiple selection.

 In this embodiment, a channel selection interface is provided for the user. After entering the multi-selection interface, the user can edit according to the current SG data.

Steps 103 to 104: After the channel is selected, the generation of the customized channel list is started; and the customized channel list is edited to obtain a customized channel list file. For each of the selected channels, the following channel information is defined: channel number Id; channel name name; channel sequence number sort. Perform XML (Extensible Markup Language) conversion on the channel information of the selected channel, and perform operations such as sorting and Id matching channels.

 The custom channel list can be sorted according to user requirements, and the order of one channel can be represented by the sequence number. Id matching channel means matching channel.id with real channel number.

 For example, the structure members of the channel are described as follows:

 struct—Channel int32 Id; 〃Channel number

 Char* name 〃 name

 Intl6 sort; / / sequence number

} Channel

 After converting to XML, it is:

 <channel>

 <Id>4292</Id>

 <Name>CCTVl</Name>

 <Sort>19</Sort>

 · ··

 </channel>

 If it is multiple channels, it is as follows:

 <channel>

 <Id>4292</Id>

 <Name>CCT V 1 </N ame>

<Sort>19</Sort> </channel>

 <channel>

 <Id>4295</Id>

 <Name>CCTV6</N ame>

 <Sort>40</Sort>

</channel>

 In this embodiment, the above content can be directly written into the specified file to implement operations such as XML conversion of channel information. The specified file refers to the file specified by the user, and the specified file written in the above content is the customized channel list file.

 In the specific operation process, the XML element defined in the XML conversion should be determined according to the content provided by the mobile TV provider, and is not limited to the above contents listed in the embodiment. Of course, in addition to the XML format, in other embodiments of the present invention, other formats, such as HTML (HyperText Mark-up Language) format, text format, etc., may be used, and related functions may also be implemented.

 Step 105: Prompt the user to use password protection. If the user selects Yes, the user is prompted to enter a password. After the system uses the encryptor to generate a password sequence according to the content of the list and the user's input encryption, the password is stored in the customized channel list file, and then step 106; If no encryption is selected, step 106 is directly executed.

 Step 106: After editing the customized channel list file, prompting the user to save the customized channel list file, if yes, saving the generated customized channel list file, and saving the generated customized channel list file as Corresponding xxx.list file; otherwise, return to step 102 to continue selecting channels from the channel selection interface for editing.

 Define a Fileid for the custom channel list file. The Fileid element marks the uniqueness of the custom channel list file, the content of which is the unique sequence produced by the encryptor.

After the above steps, the custom channel list file generation can be completed, and the generated custom The channel list file is closely related to the channel, and the other files have the same attributes as the ordinary files. They can be sent to other users through standard Bluetooth, T-card (removable flash card), infrared or MMS. shared. After the customized channel list file is generated, the user can be prompted to download all the SG data when the user starts the mobile TV, and the user can select it, so that it is not necessary to download all the SG data every time the mobile TV is started.

 When the user starts the mobile TV, the background of the terminal determines whether the current SG data is separated from the customized channel list file for a long time. If the interval is longer, such as one month, the user may be prompted to download all the SG data, so that the user can prompt the user to download all the SG data. A newer channel list is saved on the terminal.

 The process of reading the customized channel list file in the embodiment of the present invention is as shown in FIG. 2, and includes the following steps:

 Step 201: Start the mobile TV.

 During the startup process, the background of the terminal needs to determine whether the user has set a custom channel list file and whether the lock attribute is set. If the user has set, only the customized channel list file locked on the terminal is loaded, Protection of children's programs.

 The method of judging whether the user has set a custom channel list file is relatively simple, and the mobile phone TV function on the mobile terminal stores some parameters set by the user, such as the volume, the last viewed channel, etc., and one of the parameter members may be added. The new identifier, m_CustomList=TRUE/FALSE, if the identifier is TRUE (true), it means that there is a custom channel list file. If the identifier is FALSE, it means there is no custom channel list file; There is also a need to add a path identifier to identify the storage location of the custom channel list file, for example, char m_TVListPath[255] = "fs :TVf older/list/Chen Dong.tvlist", according to the path to read the specified The tvlist file, and the password is protected in the tvlist file. The password content is a sequence of passwords generated by the cipher based on the contents of the list and the password entered by the user.

Step 202: Open a custom channel list file. If the user sets a custom channel list file, after opening the custom channel list file, the expanded user interface is as shown in FIG. 3, and operations such as renaming, sorting, deleting, and saving may be performed on each channel. Different from the prior art, the present invention directly opens a custom channel list file, whereas in the prior art, a channel list is obtained from downloaded SG data.

 Step 203: Parsing a customized channel list file to generate a channel list.

, According to the elements of the XML file and the inclusion characteristics, analyze the contents of the custom channel list file one by one, starting with <61611161«>, </61611161«> is the end, and the middle of the bracket is the name of the element.

,

 And for the relationship that includes the following,

 <fileid>

 Aivksl;0skjeieokYkkksj((kd84mbujls

 </fileid>

 <password>

 Kdnlldkask9ejkkmf93858313jfnvmdlssjks-194k0987ksk

 <password>

 <channel>

 <Id>4292</Id>

 <Name>CCTVl</Name>

 <Sort>19</Sort>

</channel>

Bay ¹ J indicates channel.id=4292, channel.Name=CCTV1, channel.Sort=19. This corresponds to the channel content.

The custom channel list file is analyzed sequentially and placed in the channel list of the mobile TV, and then the channel list is sorted according to Sort (sequence number), and the Id matching channel is operated. The fileid (file number) element indicates the uniqueness of the channel list, the content of which is unique by the encryptor Sequence. The Password element then stores a sequence of passwords uniquely associated with the custom channel list file, which can be generated by the encryptor based on the contents of the list, such as the number of channels of the custom channel list file, the content, and the user's input encryption.

 Step 204: Update the parsing result to the custom channel list.

 Step 205: Play using the custom channel list.

 Since the channel.id has been matched with the real channel number, or the channel.id is actually the real channel number, the channel.id element can be used to switch channels.

 If there is no password protection, you can use the custom channel list to change channels directly. If there is password protection, the user needs to input the password. After using the decryptor to decrypt the channel content according to the password entered by the user, the user can use the channel content, which is as follows: The entered password and the contents of the list generate a password sequence, and the password sequence is used to decrypt the customized channel list file. If the decryption is successful, the user can use the corresponding channel content.

 Step 206: The terminal list can be locked and locked on the terminal.

 The user can select to lock the current channel list by pressing the specified menu after loading the channel list data, and the system prompts the user to input the terminal password, and then the terminal password is then encrypted by the encryptor according to the channel content, and the generated channel password information is written into the customized channel list file;

 Once locked, only the channels in this channel list can be used on this terminal. To use other channel lists, you must enter the terminal password to change.
