This requesting song unit with RMVB hard disc player of Kara OK function provides five kinds of requesting song modes relatively more commonly used: singer's requesting song, phonetic requesting song, stroke requesting song, languages requesting song, sort of quyi requesting song, below will introduce this several requesting song modes, the implementation of these several requesting song modes all can adopt existing ripe mode.
1, singer's requesting song:
The method that realizes: at first make a storage singer information (comprising singer's name, corresponding phonetic etc.) file and a this locality and search the song file.Singer's name is obtained from singer's message file, and the singer is when searching for, and utilizes singer's name to go to this locality to search the song information that search in the song file belongs to this singer.In order to find required singer or song sooner, provide pinyin queries.
Operating process: select the singer to put the woman singer from the requesting song unit of Kara OK function module, enter singer's name and select window; After selecting corresponding singer, enter the list of songs of singer's correspondence.When wherein selecting singer and song, can switch to own required singer or song, also can utilize pinyin queries to find desirable singer and song efficiently by the focus suitching type.
2, phonetic requesting song
Implementation method: according to the first letter of pinyin of song title, go to this locality to search in the song file and search the song that conforms to, the song that searches is shown with tabular form.Wherein, this requesting song mode is supported fuzzy search.And the method for input can adopt the focus suitching type, and this input method is more directly perceived; Also can adopt the T9 input method, directly by the corresponding digital key, can be fast.
Method of operating:, can directly import complete song first letter of pinyin if can clearly remember the name of song.If when can not determine the individual malapropism of song title, can use? asterisk wildcard replaces.
3, stroke requesting song
Implementation method: according to the first stroke of each word of song title, go to this locality to search in the song file and search the song that conforms to, Search Results is shown with tabular form.
Operating process: select the first stroke stroke of each word of song title to import by telepilot, just can inquire about by inquiry after input is finished.
4, sort of quyi requesting song
The requesting song of different groups for convenience provides sort of quyi requesting song.
Search in the song file in this locality, have a field is which sort of quyi is the expression song belong to.
Implementation method: the requesting song mode of front face is similar, just uses sort of quyi type to search in the method.
Method of operating: select sort of quyi requesting song from the requesting song unit of Kara OK function module, enter the sort of quyi and select to select the desirable sort of quyi behind the window, enter list of songs and select.Here also be to support the phonetic express query.
5, languages requesting song
With the process of sort of quyi requesting song is the same, and just the classification criterion to song is the language of song.
Utilize the requesting song mode, can find needed song track very soon.Earlier point is good a collection of oneself wants the song sung, just can begin to have sung by play button then.
In the singing process, some very necessary Play Control operations have been designed in the K song control module: cut song, sound channel switching, audio setting, video playback control etc.If desired, can also withdraw from, get back to the requesting song state, continue requesting song from the singing state.
K song control module comprises following unit:
1, cut the song unit: stop the song of current broadcast, switch to one first or next;
2, volume control unit: the just volume of output control, and do not comprise the mic volume;
3, MIC control module: support the adjusting of microphone volume adjusting and reverberation effect;
4, sound channel control module: support the switching of original singer's vocal accompaniment;
5, video control unit: support video playback, suspend F.F., rewind down, the convergent-divergent of video.
By putting shortcut, can open and put tabulation, check that the song put, deletion do not want the song of singing, the performance order of adjusting the song of having put.
Put the effect of tabulation: 1, give user prompt, the clear own song of being put; 2, can adjust the priority of putting song; 3, can directly select own favorite song to begin to play.
Method of operating: directly enter by the shortcut of point on the telepilot and to put the tabulation window.The song prompting can be deleted song by delete key by determining preferential song from putting the tabulation.Focus switched to like best on the song of singing, press play button, just can begin to play, simultaneously this first song preferentially has been placed on the first place of playlist from this focus song.
