Description
Technical field
Present technique relates to a kind of resource acquiring method and device, particularly the simple type method and apparatus of the easy operating that obtains of internet multimedia stream and radio station media resource decoding processing.
Background technology
At present, along with the continuous expansion of numerous network medias stream resources and transceiver resource is upgraded, make increasing user select network media stream and this method of service of radio station media stream resources, enjoy the fast happy convenience that it brings.The reproducting method of multimedia information source is very loaded down with trivial details and original now, the one, need huge collection, treatment facility, as: recording, video tape recorder are broadcasted tape, computer and DVD player broadcast laser disc, mp3 equipment and are downloaded the audio frequency and video data and play then from the computer of opening, and huge televisor watches fixed program or the like, and equipment and carrier are a lot of.The 2nd, because analog channel distortion or compression algorithm fall behind, cause the audio frequency and video weak effect that plays back, and be not easy to carry.The 3rd, be difficult to obtain for example long-range instant messages of instant messages, utilizing automobile mounted equipment to listen to aspect the radio station especially, can't realize that at present cross-region listens to the radio station message in real time.Existing equipment and method are difficult to address the above problem.
Summary of the invention
The present invention is the above-mentioned defective that overcomes prior art, a kind of integrated multimedia middleware device and implementation method are proposed, the collection of fund-raising source, decoding processing and transfer function can use under mobile status or stationary state by wireless or wired passage in the middleware equipment of one.This equipment need not be huge collecting device, as: computer, mp3 equipment, sound-track engraving apparatus and the DVD player etc. of band complex operations system, can directly insert audiovisual terminals, as stereophone or/and display, also or digital memeory device, conveniently receive, enjoy and handle the multimedia messages that network transmits in time.
When it uses under mobile status, can implant in mobile phone, mobile unit and mp3 or the miscellaneous equipment, by access to netwoks internets such as wireless GPS/GSM/GPRS/CDMA and IEEE802.11, handle, decode and export through multimedia middleware of the present invention.Its program or algorithm, but directly transplanting go among mobile phone or the PDA to move, advantage is to save graphic interface and loaded down with trivial details operating system, can read Internet resources at any time fast.Also can under stationary state, use, such as office or family, equally need not graphic interface and loaded down with trivial details operating system, read fast at any time and handles network resources.
The application of multimedia middleware device of the present invention can be obtained program or information source by circuit from resources bank.Described resources bank comprises each digital channel storehouse, big radio station, image and voice storehouse and other multimedia information libs that transmits through the internet, can solve the problem that listen in the strange land, and it is more convenient to make the strange land listen to.The data of described resources bank is collected in the middleware with digital mode, or directly sends to through middleware and show the equipment of broadcasting; Handling can have multiple with the form that transmits.
The main technical problem to be solved in the present invention is the equipment of the multiple online means of combination and multimedia messages processing and multiple output formats, and its volume is too huge, and inconvenience is carried.
Another technical matters that the present invention will solve is that digital multimedia device middle pitch video algorithm is outmoded and version is various, and efficient is low, and information loss is big, easily produces mosaic or interrupted tone.
The technical matters that the present invention further will solve is in the radio communication or network easily produces labile factor when switching, and for example when cdma network switches to the GSM network, may produce time-delay, causes sound, video output quality low.
It is too huge to the present invention is directed to equipment volume, the technical measures that the technical problem underlying that inconvenience is carried adopts are core I C of the brand-new function of exploitation, mode with ASIC designs independent multimedia middleware or implanted multimedia middleware on this basis, to adapt to independent use or to implant modes such as having mobile phone inside now and realize its function, with integrated form rather than combined type structure multimedia middleware device of the present invention.
It is low to the present invention is directed to efficiency of algorithm, and the technical measures that the problem that information loss is big adopts are research and development, introduce new highly effective algorithm, and for example MPEG 4, and the AVS scheduling algorithm is realized lossless compress, can not occur defectives such as mosaic after the amplification.
The technical measures that easily produce the employing of labile factor problem when the present invention is further switched at network are development, employing " seamless link technology ", corresponding each network or sound, video file, one group of isomorphism buffer zone is set, during output generation problem, pointer begins substitute at another buffer zone same position and reads, or claim " seamless jump ", do not influence output at all.
Purpose of the present invention can reach like this:
Design, make a kind of integrated multimedia middleware device, comprise storer, especially also comprise the multimedia central processing unit with the two-way network connecting module that is connected of this central processing unit.Described network connecting module comprises wired link block and wireless connections module.Described wired connection module comprises RJ45 plug connector and/or RJ11 plug connector; Described wireless connections module includes but not limited to wherein one or more of CDMA module, GPRS module, gsm module or 802.11 modules.Described integrated multimedia middleware device also comprises and two-way the touching/the number conversion output module of being connected of described central processing unit.
Employing the invention has the beneficial effects as follows the utilization by middleware, adopts the audio frequency and video algorithm of optimizing, and implants middleware module, puts into mobile phone or PDA product, with the accesses network multimedia resources database.In the way of driving, substitute existing vehicle-mounted audio frequency and video audiogenic device, obtain the strange land station broadcast that existing equipment can't be listened to, set up the connection between remote resource and the mobile subscriber very easily, solve region this barrier of factor by network.
