Description
[technical field]
The invention relates to a kind of digital television signal processing system, more detailed it, relate to a kind of digital television signal processing system of employing wireless Bluetooth transmission technology.
[background technology]
Year more than the application of TV receiving system is gone already, and early stage TV receiving system is sent to the radiation pattern of video signal content with radio wave on the display mostly, but be accompanied by being showing improvement or progress day by day of science and technology, visual effect tends to gradually dynamically to reach the presentation mode of innovation, content of multimedia is also increasingly sophisticated, relatively, the information flow-rate that presents is also increasing, therefore provide the TV receiving system of big frequency range and image quality also to arise at the historic moment with coaxial wire (cable), at present be with the coaxial wire transmission medium TV receiving system because its to have laying speed fast, popularity rate height and the characteristic that is easy to lay, accepted and used by popular, but therefore the step of scientific and technological progress can't stop, nowadays the TV receiving system of Digital Television germinates healthy and strong gradually, by bragging about the digital signal TV station that has DTV receiver just can receive hundreds of easily wirelessly to find out, in the rating mode transformation silently now, therefore, the wireless transmission method that carries out transmitting/receiving program with wireless digital signal substitutes the wire transmission mode of original coaxial wire gradually, it provides bigger frequency range, more information source and wireless transmission method bring higher convenience and action edge for the user whereby.
But, present wireless digital TV-set observer is still based on general family, and the wireless high action edge characteristic of bringing still can't represent substantially, its main cause is that DTV receiver is carried inconvenience and is equipped with antenna, can't receive digital television signal with the occupation mode of hand-held device, in view of this, just there is the dealer to provide the user charge of television program receiving demand to download in the mode of GPS, yet, too high with the cost that this GPS mode is set up, the user still need carry out one and download action, just can watch the download content, its operation inconvenience is its subject matter, in addition, it is higher to charge, and is not that ordinary consumer can be accepted.
With the wireless transmission notion and improve action edge and convenience is the design of purpose, announce M248141 patent case as TaiWan, China and propose bluetooth hard disk receiver, it is with the notion of wirelessly transmitting data, borrow and promote convenience between transfer of data, to reach the hard disc data of the common access tool of computer Bluetooth function, avoid substituting the inconvenience that use brought of installing and wire rod, and the content of transmission there is no and is confined to lteral data, view data, voice data, and video-audio data.
Yet, above-mentioned patent case only is a kind of scheme that receives video-audio data in the Bluetooth wireless transmission mode by a portable storage device, therefore, it only provides a kind of transmission mode of data, and can't watch this video-audio data in real time, that is, the reception that can't be applied to digital television signal with watch, only for improving inconvenience and the cost saving that GPS pays and downloads, in addition, must have a video-audio data of desiring to transmit in advance in the bluetooth hard disk in this patent case, so purposes is confined to existing video-audio data, only promote action edge and convenience with the wireless transmission notion, but non-effect with real-time rating.
Therefore, how effectively to solve the existing problem of aforementioned techniques, and develop the system of receiving digital television signal in real time, convenience and the real-time of information acquisition, the problem that present wireless TV receiving system needed to be resolved hurrily just during with effective lifting rating demand.
[summary of the invention]
