Description
Technical field
The present invention relates to video data processing apparatus.
Background technology
In recent years, be accompanied by the development of Radio Transmission Technology, a kind of video data processing apparatus that possesses transmission unit has been proposed, this transmission unit uses the electric wave on the frequency band that only has limited high-speed channel, to video display devices wireless transmission video initial data (Video raw data) (with reference to patent documentation 1).
For example, in above-mentioned existing technology, as shown in Figure 1, the video data processing apparatus 20,30 of DVD, STB (TV set-top box) etc. is wirelessly transmitted to unpacked data (for example sound, picture signal etc.) separately in the display 10.At this, by being connected setting up high-speed channel between video data processing apparatus 20,30 and the display 10 respectively, thereby carry out this wireless transmission with two-forty (for example being more than the 3Gbps).
Yet, because the restriction that radio band is utilized in the world, thereby the employed high-speed channel number of wireless transmission is conditional.As described in non-patent literature 1, only there are 3 high-speed channels to can be used for above-mentioned wireless transmission.Therefore, when having 3 pairs of wireless high-speed transmission links (passage), can't rely on increases hardware and realizes that the 4th video data processing apparatus is to the display unit transmitting video data.And it is not technical reason that frequency band uses limited, can't be overcome by technological progress.
Therefore, in the invention of patent documentation 1 record, under situation, certainly exist certain two video data processing apparatus and use same high-speed channel to carry out the situation of wireless transmission with the video data processing apparatus more than the high-speed channel number.Be that video data processing apparatus 20,30 uses same high-speed channel to carry out wireless transmission, produce the problem of disturbing between the video data processing apparatus 20,30 thereby exist.Therefore, transmission system is after cutting off display 10 and high-speed channel between the video data processing apparatus 20 is connected, selection from the signal of video data processing apparatus 30 as input video source, and set up display 10 and be connected with high-speed channel between the video data processing apparatus 30, carry out wireless data transmission, thereby prevented the interference of the signal between the video data processing apparatus 20,30.
But, after cutting off display 10 and the high-speed channel of video data processing apparatus 20 be connected, need set up display 10 is connected with high-speed channel between the video data processing apparatus 30, need on the one hand repeatedly alternately to realize that physical connection, logic connect and the resource occupation statement, on the other hand, for the radio communication of some video data processing apparatus, its physical connection is to direction sensitiveness very high (promptly having high directivity), the each connection must be redirected by physics, and be consuming time longer.Therefore, based on the invention of patent documentation 1 record, during transmitting video data, the demonstration that a period of time will inevitably occur is interrupted, and does not promptly have image to show in the display in the limited wireless communication system of frequency band.
