Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention will be described, wherein:
Fig. 1 is the functional block diagram of DST PLAYER of the present invention;
Fig. 2 is the front-end view of DST PLAYER of the present invention;
Fig. 3 is the hardware function schematic diagram of DST PLAYER of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Be the functional block diagram of DST PLAYER of the present invention as described in Figure 1, the present invention is directed to existing DST PLAYER in the process sent request, easily occur that when carrying out playing stream media obstruction and state are not easy the problem judged, cause playing the problem occurring being interrupted, card pauses, whole system is carried out layered shaping.As shown in Figure 1, system is divided into application layer 100, streaming media playing layer 200 and network layer 300.Network layer 300 is for from service end download stream media, and the Streaming Media of download is first kept in buffer memory (not identifying in the drawings), and play by streaming media playing layer 200, while broadcasting, network layer 300 carries out the download action continued.Adopt this present next part Streaming Media to carry out buffer memory, then while playing, download the mode of remaining Streaming Media simultaneously, the broadcasting Caton phenomenon produced because of the fluctuation of network can be avoided.
Application layer 100 comprises following sub-function module: initialization module, for making DST PLAYER return to initial condition, empties buffer memory; Play/suspend module, carry out playing and the switching suspending two states for the files in stream media in control flow check media play layer 200 pairs of buffer memory; Upper head/lower first module, when this module activation, streaming media playing layer 200 suspends the broadcasting to current files in stream media, network layer 300 also suspends the download to current files in stream media simultaneously, network layer 300 sends the download request to upper or next files in stream media to server, and in buffer memory, point space made new advances is preserved this newly downloaded files in stream media; Stopping modular, for making streaming media playing layer 200 quit work, and discharges spatial cache; Online query module, when this module is activated time, network layer is to the list of server request download file, and this listed files corresponds to all files in stream media preserved in server; Exit module, for closing DST PLAYER; State display module, for showing the mode of operation of current DST PLAYER, such as, suspends broadcasting, inadequate buffer space etc.
If Fig. 2 is the front end embodiment made according to Fig. 1 functional module.In this embodiment, each sub-function module of application layer 100 makes the button of push type: broadcasting/Pause key 101, stop key 102, upper first key 103, lower first key 104, online query key 105, ESC Escape 106, state display field 107.In this front end, also comprise viewing area 201, the characteristic information of the files in stream media for display video type or the display of the files in stream media for audio class audio file, the audio frequency moire pattern etc. of such as bit rate, Streaming Media.
When pressing broadcasting/Pause key 101, corresponding broadcasting/time-out the module activated in application layer 100, when switching to broadcast state, network layer 300 is from server download stream media file and be saved in buffer memory, when the Streaming Media of buffer memory reaches the lowest threshold of played file, streaming media playing layer 200 carries out the broadcasting of file; While broadcasting, network layer 300 continues streaming media files and downloads.If now again press broadcasting/Pause key 101, then DST PLAYER is switched to halted state, picture when now viewing area 201 is fixed on time-out, and halted state is entered into by word or image display DST PLAYER now in state display field 107.Network layer 300 does not change download action, and lasting streaming media files proceeds to download, until press stop key 102 or ESC Escape 106.
First key 103 or lower first key 104 on pressing, the corresponding upper head/lower first module activated in application layer 100, now suspend the broadcasting to current files in stream media, network layer 300 also suspends the download to current files in stream media simultaneously, network layer 300 sends the download request to upper or next files in stream media to server, in buffer memory, point space made new advances is preserved this newly downloaded files in stream media, after the frame number of the file obtained when buffer memory is enough play, this files in stream media of automatic activation is play, and continues to carry out download stream media file simultaneously.
When pressing online query key 105, DST PLAYER sends inquiry request to service end, and to obtain download file list, this listed files corresponds to all files in stream media preserved in server, open a new interface in front end, in order to show the listed files that this obtains simultaneously.Bandwidth shared by the information of listed files and inquiry request is all few, and DST PLAYER can be oestrused in the process of cache file at the same time online query, and without the need to suspending video or tentatively downloading.
Be more than the preferred embodiment that the present invention is applied to when front end shows, for the app etc. of different platforms such as PC, iOS, various intelligent mobile phone system, which can be adopted to realize online browse files in stream media.It will be appreciated that this front console also can be implemented as the user interface of hardware, each function button is arranged as physical button, and such as ESC Escape 106 is as the closedown button of power supply, and viewing area 201 corresponds to liquid crystal display etc.
When the present invention is as hardware implementation time, the functional module structure of its inside as shown in Figure 3, DST PLAYER comprises network transceiving module, flow medium buffer device, playing module and control module, wherein flow medium buffer device interconnection network transceiver module, playing module and control module respectively, control module is also connected with network transceiving module, playing module.
Network transceiving module is by wired connection mode, such as RS485 interface, RS232 interface, or the mode of wireless connections, as WIFI, infrared etc., communicate to connect with the server of far-end or the transfer route etc. of this locality, so that server distally obtains Streaming Media.When the Streaming Media obtained, be first kept in flow medium buffer device, when the buffer memory of Streaming Media is to the frame number enough play, the carrying out in playing module streaming media buffer is play.
While playing stream media, network transceiving module proceeds download stream media from server, and the part downloaded to is continued in flow medium buffer device.Like this, even if network transceiving module cannot receive files in stream media at short notice because of network fluctuation, also can not the normal play of image playing module.
Control module is used for controlling whole DST PLAYER.Such as by the connection with playing module, control playing module each action in the playing process of files in stream media, such as, play/suspend, a upper head, next etc.Control module, by the connection with flow medium buffer device, to realize the control to spatial cache, such as, is play in next in selection, opens up new space with the new files in stream media of buffer memory in flow medium buffer device.Control module is by the connection with network reception module, and when carrying out online query, solicited message sends from control module, and sends inquiry request by network transceiving module to server.Each control command of control module is all corresponding with the application layer sub-function module in Fig. 1.
These are only the specific embodiment of the invention, scope of the present invention can not be limited with this, the equalization change that those skilled in the art in the art do according to this creation, and the change that those skilled in that art know, all still should belong to the scope that the present invention is contained.
