Embodiment
Describe the present invention below in conjunction with accompanying drawing.
Fig. 1 is the process flow diagram based on the random player method of DMA of the embodiment of the invention, and as shown in Figure 1, the method for the embodiment of the invention may further comprise the steps:
Step 101: DMA receives the order from telepilot; Identify said order,, then carry out by the normal commands that identifies if not arbitrarily broadcast order; When being the switching command of television channel like order; DMA will switch the channel that the active user selectes, owing to non-ly arbitrarily broadcast the improvement that pattern is not a technical scheme of the present invention, not repeat them here; If arbitrarily broadcast order, then get into step 102.
Pattern and television program mode are arbitrarily broadcast in DMA support of the present invention, and wherein, arbitrarily broadcasting pattern is emphasis of the present invention, arbitrarily broadcast under the pattern at this, and DMA will be play the multimedia file in the file of user's appointment automatically.Because the play mode that DMA is supported is more; Therefore corresponding control command is also many; Input command key on the telepilot is also more, for each user's button, all corresponding to control commands corresponding; These control commands are corresponding to unique encoding, and can be discerned by DMA.DMA receives from after the control of remote controller order, needs identification to order, if the current command for arbitrarily broadcasting order, then need switch to and arbitrarily broadcast pattern.
The enter key of arbitrarily broadcasting order of the present invention is realized that by the button on the telepilot this button is defined again by existing button on the telepilot and forms, and is the shortcut of resetting; Perhaps, the enter key of arbitrarily broadcasting order is a new button ad hoc on the said telepilot.Arbitrarily broadcasting the enter key of order can encode and realize through increasing new guidance command, the respective coding mode is recorded can discern in the DMA get final product.
Step 102: judge DMA current whether be the pattern of arbitrarily broadcasting, if then get into step 103, if not then get into step 104.
Of the present invention broadcast arbitrarily that pattern refers to the current broadcast of DMA be with exterior terminal that DMA is connected on specified file.Said exterior terminal comprises any terminal of supporting multimedia; Like personal computer, notebook, personal digital assistant, mobile phone, MP3, MP4 etc.; On these exterior terminals, specify a multimedia file folder, as the multimedia file of DMA appointment, when receive the user arbitrarily broadcast order after; DMA is given tacit consent to the multimedia file in the multimedia file of having selected said appointment, selects a multimedia file to play at random.If the current broadcast of DMA is the multimedia file in the multimedia file of appointment, then is in and arbitrarily broadcasts pattern, otherwise be in the non-pattern of arbitrarily broadcasting.Can be connected through wired or wireless mode between said exterior terminal and the DMA, the interface of connection comprises USB mouth, wired network interface, wireless network interface, pci interface, E1 interface etc.Whether can have multimedia data stream to confirm that current whether being in of DMA arbitrarily broadcast pattern through judging above-mentioned connecting interface, above-mentioned connecting interface be in the pattern of arbitrarily broadcasting when multimedia data stream is arranged.
Step 103: the file of changing current broadcast.This step has two kinds of tupes, and one of which judges in the played file folder of appointment whether also have the file outside the current played file type, if there is in the then selected other types file arbitrary file play; If the played file of appointment folder only has one type played file, then judge whether to have more than one file, play if then choose an alternative document wantonly, otherwise do not deal with.For multimedia file, mainly be audio file, video file etc., its type is a lot, and like audio file of film and television type file, music type etc., the user externally carries out classification and storage in the terminal, can store classifiedly by file.DMA is current arbitrarily broadcast receive again under the pattern user arbitrarily broadcast order the time, be defaulted as this order and be played file type switching command, then judge currently whether also have the alternative document folder, if the multimedia file of then playing in the alternative document folder is arranged.Played file type switching command also can resolve to the switching command between video file and the audio file.
Its two, judge in the played file folder of appointment whether have more than one file, if then optional alternative document is play, otherwise do not deal with.This processing mode promptly is arbitrarily to switch between multimedia file all in the played file of appointment folder, not the branch of type.
Step 104: whether be empty in the played file folder of inquiry appointment, if the empty information of then returning no played file, if then in the played file folder of said appointment, do not select a file to play at random for empty.
For the current non-situation of arbitrarily broadcasting pattern of DMA, need it be switched to the pattern of arbitrarily broadcasting.At this moment; Whether the played file folder of at first confirming appointment is addressable, if the connecting interface interrupt situation occurs, then returns the information of no played file; If find appointment played file folder but for empty or wherein do not have a multimedia file; Then return the information of no played file,, then choose one of them wantonly and play as if having multimedia file in the played file folder that finds appointment.
Step 105: current file finishes, and selects files automatically and plays.The present invention supports two kinds of selected modes; One of which, current file finishes, and judges in the played file folder of appointment whether also have alternative document in the current played file type; If have then in said alternative document selected arbitrary file play, otherwise repeat play current file.Its two, current file finishes, and judges whether the played file folder of appointment also has alternative document, if there is then in said alternative document a selected file play, otherwise the repeat play current file.
Fig. 2 is the DMA of the embodiment of the invention and the interaction diagrams of exterior terminal, and is as shown in Figure 2, and in the present embodiment, exterior terminal is a personal computer PC, and its interaction flow comprises:
Step 201: after DMA DMA receives and arbitrarily broadcasts order, send request, to obtain the multimedia file tabulation that to play to PC;
Step 202:PC receives the inquiry playable media file request of DMA;
Step 203: search PC and go up the multimedia file that to play in the appointment media library, generate the multimedia file playlist;
Step 204:PC is sent to DMA with the multimedia file playlist;
Step 205:DMA receives the multimedia file playlist that PC sends;
Step 206: judge whether the multimedia file playlist is empty;
Step 207: when judgement has the media file that can play, from the multimedia file playlist, select a played file at random;
Step 208:DMA sends this order that selects files of shuffle to PC;
Step 209:PC receives the playing request of DMA;
The multimedia file that step 210:PC treats broadcast carries out pre-service, for said multimedia file is chosen corresponding player etc.;
Step 211: play said multimedia file, send the multimedia file data of playing to DMA in real time;
