Embodiment Construction

[0018] The present invention will be further described in detail below through specific embodiments and with reference to the accompanying drawings, wherein the description takes 802.11a as an example, but those skilled in the art should understand that the present invention is also applicable to other wireless broadband transmission systems.

[0019] See Figure 4 As shown, the present invention adds a series of circuits before the original transmitting module, so as to realize the leap from one-to-one transmission to N-to-N transmission (wherein N is a natural number greater than 1). Figure 5 It is described by taking N equal to 2 (that is, 2 to 2) as an example. However, those skilled in the art should understand that the circuit can also be extended to the situation when N is greater than 2.

[0020] Depend on Figure 4 It can be seen that the present invention first amplifies multiple input signals, couples them to multiple audio and video switching circuits, and selec...

Abstract

Present invention many to many wireless transmission device including radio emission module and two-way or multiplepath inputting message source. It features including amplification-distribution via circuit, sound video switching circuit and central processing unit, wherein each inputting message source accessing to sound video switching circuit through respective amplification-distribution via circuit, said way sound video switching circuit controlled by relevant central processing unit, under processing unit controlling, selecting one way in multiplepath inputting message source and outputting to said radio emission module. Utilizing CPU controlling sound video switching circuit switching circuit, user can select one way signal to view without infection other user.

Description

Technical field: [0001] The invention relates to a many-to-many wireless transmission device, in particular to a many-to-many wireless video broadband transmission technology. Background technique: [0002] Home audio-visual equipment with wireless transmission function avoids the inconvenience of wired system wiring due to its use of wireless video broadband transmission technology, and has great advantages in mobility and convenience of home decoration. It is the development direction of future home audio-visual systems. one. [0003] Currently relatively fluent wireless video broadband transmission products include 802.11a, 802.11b, 802.11g, etc. For example, the 802.11a product of adimos company is a typical representative product, which can realize wireless video broadband transmission technology. Such as figure 1 As shown, in the transmitting module, through A / D conversion, coding and adding the standard protocol of 802.11a, and then transmit from the antenna throug...
