The playing selection method comprises that firstly, a requirement signal for option windows is transmitted from the multimedia player to the server; then, when the server receives the requirement for the option windows, the option widows of the multimedia files are transmitted to the multimedia player; the option window is formatted and inserted into an output image of the end of the multimedia player; when a user sees the output image from a display, the end of the multimedia player selects one multimedia file through the option windows; selected items are transmitted to the server through the option windows; the multimedia files corresponding to the selected items are transmitted to the multimedia player through the server; the multimedia player is used for receiving and playing or storing the multimedia files.
Description
Technical field
The present invention relates to a kind of method of selecting play multimedia files, particularly relate to a kind of method that the multimedia file on-line selection that is stored in server can be play or stored.
Background technology
Multimedia file is a kind of digital data file in conjunction with acousto-optic and image, generally speaking, the file content of multimedia pattern is bigger usually, therefore must utilize compress technique, as MPEG2 or MPEG4 etc., with multimedia file compression, and among the bigger discs of the capacity that is stored in, as the DVD discs.In case in the time of will carrying out the broadcast of multimedia file, then be to utilize DVD player that the DVD discs is decompressed and decipher, the multimedia file after will deciphering again exports display to and plays.
DVD player still is only limited to the function that play in zone (local) at present, and its broadcast mode is that a slice DVD discs is put into DVD player, broadcasts by a display content of this sheet DVD discs is broadcasted.But many times, read the hearer and do not carry the DVD discs at one's side, or its DVD discs has at one's side all been seen, at this moment, readding the hearer just must go out and choose or rent sheet, yet no matter be to go out to choose or rent sheet, its whole process not only bothers, time-consuming but also can cause and read the suitable inconvenience of hearer.
Universalness along with network, directly utilize a player to receive multimedia file by network online, be employed widely in order to the technology of playing long-range film, the most normal framework that uses is browser/website (browser/website) master-slave architecture at present, the necessary built-in browser software of player under such framework, player can be a personal computer, enter the webpage of server end and click the multimedia file that institute's desire is play by browser, again with RTP (real-time transportprotocol, be called for short RTP), or HTTP, TCP, communications protocol such as GUI are downloaded multimedia file, utilize crossfire (streaming) technology to carry out the audio-visual broadcast of real-time multimedia at last again.But because above-mentioned communications protocol only is fit to the transmission of literal or webpage; and be not suitable for transmission as video-audio data; therefore picture is through regular meeting's distortion in the process of transmission for streaming media, and in addition, the deficiency of network bandwidth and transmission speed also can have influence on the quality of appreciation slowly.
Another kind of framework is terminal organ/server client/server, under this framework, player is set the terminal organ end for, and login (login) to server end by network interface, in communications protocol modes such as RDP or GUI multimedia file is downloaded again, utilized crossfire (streaming) technology to carry out the audio-visual broadcast of real-time multimedia at last again.This framework and foregoing structure all have problems such as transmission rate deficiency and picture be intermittent to produce, and the control of transfer of data is all at server end rather than at terminal organ device end.Therefore, when the terminal organ quantity that is online to server end gets more and more, being embedded in the transplanting workload (porting work) that the real time operating system (RTOS) of server end carried out also can increase, therefore in the process of transfer of data, cause online interruption because the load of RTOS is excessive or also can often take place when the situation of machine.
Therefore,, propose a method that has the on-line selection play multimedia files of transmission rate and transmission quality concurrently, read the better rating quality of hearer, be the be correlated with problem place of the anxious desire solution of practitioner of present stage in fact to provide how at the shortcoming of known technology.
Summary of the invention
Main purpose of the present invention provides a kind of method of on-line selection play multimedia files.
The disclosed on-line selection of the present invention is play framework and is comprised a server and a multimedia player, there are many multimedia files in the server interior reservoir, multimedia player has the function of play multimedia files, wherein interlink by network between multimedia player and the server, and be set under the network architecture of equity (peer to peer).
When the multimedia player desire was carried out the real-time broadcast of multimedia file by network, it was play step and comprises: at first send an option forms requirement signal by multimedia player to server end; When server when obtaining option forms requirement signal, then be that the option forms with many multimedia files transfer to multimedia player; Multimedia player inserts this option forms content formatting the image output of multimedia player; After the user sees image output via display, in the option forms, select the multimedia file of institute's desire broadcast again by the multimedia player end; By the option forms project that is clicked is sent to server; To click the pairing multimedia file of project by server again and be sent to multimedia player; Utilize the multimedia player reception and export multimedia file to multimedia player is play or multimedia file is stored in to a display inside.
Above-mentioned option forms can be the html file form, it is numbered each multimedia file of server inside, and indicate the identification feature of each multimedia file, comprise film title, film character, publish producer and featured performer etc.The option of forms then be with the hyperlink mode be assigned to its corresponding multimedia file storage location or add the controlled function of multimedia player, therefore, when a certain project in the option forms by after being clicked, its pairing multimedia file will be sent to the multimedia player end with crossfire (streaming) transmission means, export a display again to and carry out that on-line selection is play or multimedia file is stored in the multimedia player.
In addition, also can be to be set under the ad-hoc pattern between multimedia player of the present invention and the server, and carry out wireless data transmission by WLAN (WLAN) IEEE 802.11.The option forms of the multimedia player that is downloaded to then are to control the image signal that (OSD) pattern is inserted the output of multimedia player end with screen display, thereby show on the display, therefore for the user, it can be by the remote controller in the hand, the options menu that OSD on the screen is shown is selected, and the multimedia file that institute's desire is play directly carries out online broadcast or storage.
Wherein, can interlink by the ether express network between above-mentioned multimedia player and the server, or utilize IP privately-owned network (VPN) to interlink, or even interlink by inner private line network, no matter be that transmission speed or image quality can promote significantly therefore.In addition, because the present invention will be set between multimedia player and the server under the shared network architecture of equity, and control is to be set in the multimedia player end, therefore for the real time operating system that is embedded in server end (RTOS), even under the situation of multi-section multimedia player while data download, also can not increase the transplanting workload (porting work) of server end, relatively, in the process of transfer of data, online interruption takes place or also can reduce to minimum when the situation of machine.
For making those skilled in the art person can understand purpose of the present invention, feature and effect really, will be described below embodiments of the invention in conjunction with the accompanying drawings.
