In description of the invention, it will be appreciated that term " first ", " second " etc. only are used for describing purpose, and can not be interpreted as indication or hint relative importance.In description of the invention, need to prove that unless clear and definite regulation and restriction are arranged in addition, term " links to each other ", " connection " should do broad understanding, for example, can be to be fixedly connected with, and also can be to removably connect, or connect integratedly; Can be mechanical connection, also can be to be electrically connected; Can be directly to link to each other, also can indirectly link to each other by intermediary.For the ordinary skill in the art, can concrete condition understand above-mentioned term concrete meaning in the present invention.In addition, in description of the invention, except as otherwise noted, the implication of " a plurality of " is two or more.
Along with the development of microelectric technique, its equipment with wireless connections the picture output device of SD card overall dimension appearred having, simultaneously.When this equipment is inserted in the SD/USB slot of media player, these equipment are resource playing stream media content from network just.Because network media file physically is not stored on the SD card, but obtain from Internet resources, if main process equipment (such as TV) has the preview mode of video file, so when the user browses a video file (but not playing) in the file, owing to the file data that does not have to provide immediately, the wireless computer device with SD card overall dimension is not supported the TV preview function.And for those TVs with preview function, if its preview failure, can displaying video yet, because it thinks that this document damages.The present invention has designed device and method and has supported TV preview video file, and need not to add extra nextport hardware component NextPort.
As shown in Figure 1, be the structure chart according to the Streaming Media pre-viewing device 1 of the embodiment of the invention.This Streaming Media pre-viewing device 1 comprises: from engine 110, and Streaming Media module 120, wireless connections module 130 and virtual file mapping database 140.Wherein, be used for receiving reading file request and sending Streaming Media module 120 to of player 2 transmissions from engine 110; Streaming Media module 120 with link to each other from engine 110, Streaming Media module 120 control wireless link modules are from online Media resource 3 download files; Wireless connections module 130 links to each other with Streaming Media module 120, is used for downloading preview header file and preview tail file with wireless mode from online Media resource 3; And virtual file mapping database 140 links to each other with Streaming Media module 120, is used for storage and downloads preview header file and the preview tail file that obtains.
Alternatively, Streaming Media module 120 further comprises: judge module, judge module are used for judging that whether player 2 is access stream media file first, if access first, then Streaming Media module 120 reads preview header file and preview tail file.
Alternatively, Streaming Media pre-viewing device 1 is USB or SD card structure, links to each other with player 2 by the USB/SD socket.
As shown in Figure 2, the Streaming Media method for previewing of the embodiment of the invention comprises: S1. links to each other with the Streaming Media pre-viewing device of claim 3 player by USB socket or SD slot; S2. player is through sending read request from engine to the Streaming Media module; S3. the Streaming Media module judges that whether player is access stream media file first, if yes then enter step S41 to S43, if not then entering step S51 to S52; S41. the wireless connections module is downloaded the preview header file or preview tail file is stored in the virtual file mapping database from the online Media resource; S42. read preview header file or preview tail file in the virtual file of Streaming Media module from the virtual file mapping database; S43. the Streaming Media module is through returning response from engine to player, and player is to user's playblast header file or preview tail file, to realize user's preview; S51. the Streaming Media module obtains files in stream media by the wireless connections module from the online Media resource; S52. the Streaming Media module is through returning response from engine to player, and player is play to realize the user to user's playing stream media file.
To sum up, flow module has increased preview header file and preview tail file in the technical solution of the present invention, supports the main process equipment previewing programs, and it has following two kinds of enhancing functions to process preview: the background of (1) preview file is prepared.Because comprise the information (they are mapped as virtual file in the FAT table) of all Online Video files in the virtual file mapping database.Whenever available in the Internet connection, when the Streaming Media module can be downloaded on the backstage preview header file and preview tail file.(2) determine that from the read requests of main process equipment be preview or the function of broadcast.Because for the main process equipment with preview function, it can all media contents of automatic preview when the user browses a new file.
Put it briefly, core of the present invention is when media file request was read in transmission, the Streaming Media module can judge whether it is that a preview is read, and if so, then finds the pre-review information of this file and return to player from the virtual file mapping database; And if not preview request, then directly by wireless connections downloading video files data and return to player from the network.Virtual file in the virtual file mapping database can upgrade automatically, and when the Internet connection was available, the Streaming Media module can be downloaded on the backstage preview header file and preview tail file.
Need to prove that each virtual file in the virtual file mapping database be separately to should there being a preview header file, and for all virtual files in the virtual file mapping database to a public preview tail file should be arranged.The user may need to read some pieces from the head of video file and come the capturing pictures thumbnail, then jumpily reads the time span that some tail pieces calculate this video file.The size of preview header file and preview tail file depends on the realization of main process equipment preview function.Yet it also has a scope.Generally, it will read from video heads and be less than 30 seconds data, read video data less than 5 seconds from the video afterbody.The size that to translate this time scope be video file (the supposition video is 720 * 576 resolution, H.264 coding), it approximately is less than the preview header file of 5MB with less than the preview tail file of 1MB.
The apparatus and method of the embodiment of the invention can be applied in the players such as these TVs, for the user provides preview, have advantage easy and simple to handle, make things convenient for the user to increase the experience of product.
