Fig. 1 is the search of the video disc based on Android platform Play System in embodiment;

Fig. 2 is the process flow diagram of the search of the video disc based on Android platform player method in embodiment.

Embodiment

Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited to this.

Embodiment

As shown in Figure 1, a kind of search of the video disc based on Android platform Play System, comprise: microprocessor and the output module being connected with microprocessor respectively, load module, the second memory module and video disc, described output module comprises voice-output unit and touch display screen, and described load module and output module share same touch display screen.The first memory module that described video disc comprises mpeg module and is connected with mpeg module, described mpeg module is connected with microprocessor.

Described mpeg module is used for the video disc list information of the first memory module of obtaining video disc, and decode, decoded video disc list information is sent to microprocessor, according to received simple ID, obtain in the first memory module corresponding file content, and transfer to output unit and play.

Described the first memory module is for storing the file content of video disc list information and video disc.

Described microprocessor is used for receiving the decoded video disc list information of mpeg module, and is stored in database table; According to the video disc list information in keyword search information search database table, and Search Results is transferred to output module; Obtain the simple ID that selects played file, and transfer to mpeg module.

Described the second memory module has been set up a database in advance, and sets up and have one for storing the database table of video disc list information in database.

Described load module is used for the keyword search information of user's input, selects played file communication to microprocessor.

Described output module, for keyword search result is carried out to output display, will receive the file content of mpeg module, and plays.

As shown in Figure 2, a kind of video disc search broadcasting method based on above-mentioned video disc search Play System, its implementation procedure is as follows:

S1 is at the second memory module building database in advance of said system, and in database, sets up corresponding database table.Be specially and in the corresponding space of memory module, set up the buffer memory of a database file using db as suffix as data, the database that android carries as adopted helps class " SqliteOpenHelper " to create the database of a media.db by name, then according to relevant attribute, set up corresponding database table, the foundation of database table adopts the list mode of setting up of Android platform standard.Described database table comprises following attribute: the simple ID(-id that video disc list information is corresponding), father ID(parentid), medium type (types), file name (filename), song type (clips) and file identification (isfile), described file attribute file identification is for judging that corresponding file is song or file, if file can launch.Described file comprises song and file.Described song type (clips) comprises audio file, picture file and video file.The song type of described medium type for comprising under log file folder.

S2 microprocessor detects after video disc works on power and sends list request information to mpeg module.

S3MPEG module is obtained the list information of video disc from the first memory module of video disc, and will after obtain list information decoding, be sent to microprocessor.

S4 microprocessor is stored to decoded video disc list information in the database table of setting up in advance.

S5 microprocessor adopts dynamic load mode to load and shows the data in database table.Wherein, in during display list, only song title and Folder Name are shown.

S6 is when user wants to play a certain first song, and user obtains corresponding song title by keyword search mode.Be specially user and pass through load module, as touch display screen, the character of input keyword search or phrase are to microprocessor, microprocessor is according to qualified All Files in the character of user input or phrase searching database table and show with tabular form, and user selects concrete play list according to shown list.As, user inputs " sea " word by touch display screen and searches for, microprocessor All Files folder and song that title comprises " sea " word in search database table, and file and the song of searched comprising " sea " word are shown with tabular form.

S7 microprocessor is sent to mpeg module by the simple ID of selected play list.Because each song or file have a unique simple ID and its upper level ID, therefore just can obtain corresponding simple ID and father ID as long as obtain file name (file name is song title or Folder Name), just be not subject to the impact of level, reduce the complexity realizing.

S8MPEG module is obtained the content of corresponding song in video disc and is forwarded to playing module according to received simple ID and plays.In addition, user can arrange corresponding playing sequence by touch display screen according to personal like, and dirigibility is high, and user experience is good.

Above-described embodiment is preferably embodiment of the present invention; but embodiments of the present invention are not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present invention and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection scope of the present invention.
