Describe the present invention below in conjunction with accompanying drawing.
Fig. 1 is the process flow diagram based on the random player method of digital media adaptor 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: digital media adaptor receives the order from telepilot, identify described order, if not arbitrarily broadcast order, then carry out by the normal commands that identifies, when being the switching command of television channel as order, digital media adaptor will be switched the channel that the active user selectes, owing to non-ly arbitrarily broadcast the improvement that pattern is not a technical solution of the present invention, not repeat them here; If arbitrarily broadcast order, then enter step 102.
Pattern and television program mode are arbitrarily broadcast in digital media adaptor support of the present invention, and wherein, arbitrarily broadcasting pattern is emphasis of the present invention, arbitrarily broadcast under the pattern at this, and digital media adaptor will be play the multimedia file in the file of user's appointment automatically.Because the play mode that digital media adaptor is supported is more, therefore corresponding control command is also many, input command key on the telepilot is also more, button for each user, all corresponding to control commands corresponding, these control commands are corresponding to unique encoding, and can be discerned by digital media adaptor.Digital media adaptor receives from after the control of remote controller order, needs this order of identification, if the current command for arbitrarily broadcasting order, then needs to switch to the pattern of arbitrarily broadcasting.
The enter key of arbitrarily broadcasting order of the present invention is realized that by the button on the telepilot this button is redefined 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 described telepilot.Arbitrarily broadcasting the enter key of order can encode and realize by increasing new guidance command, the respective coding mode is recorded can be discerned in the digital media adaptor get final product.
Step 102: judge digital media adaptor current whether be the pattern of arbitrarily broadcasting, if then enter step 103, if not then enter step 104.
Of the present invention broadcast arbitrarily that pattern refers to the current broadcast of digital media adaptor be with exterior terminal that digital media adaptor is connected on specified file.Described exterior terminal comprises any terminal of supporting multimedia, as personal computer, notebook, personal digital assistant, mobile phone, MP3, MP4 etc., on these exterior terminals, specify a multimedia file folder, multimedia file as the digital media adaptor appointment, when receive the user arbitrarily broadcast order after, digital media adaptor is given tacit consent to the multimedia file in the multimedia file of having selected described appointment, selects a multimedia file to play at random.If the current broadcast of digital media adaptor is 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 by wired or wireless mode between described exterior terminal and the digital media adaptor, 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 determine that current whether being in of digital media adaptor arbitrarily broadcast pattern by judging above-mentioned connecting interface, above-mentioned connecting interface be in the pattern of arbitrarily broadcasting when multimedia data stream is arranged.

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 described appointment, do not select a file to play at random for empty.
For the current non-situation of arbitrarily broadcasting pattern of digital media adaptor, it need 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 return 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, 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 described alternative document selected arbitrary file play, otherwise repeat playing 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 described alternative document a selected file play, otherwise the repeat playing current file.
