(4) description of drawings
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, especially exemplified by preferred embodiment, and cooperate appended graphicly, be described in detail below:
Fig. 1 represents wireless network accessing apparatus of the present invention.
(5) embodiment
Main purpose of the present invention is at wireless network accessing apparatus (Access Point, AP) function that adds image processing in, allow the user reach the integration electronic product and to make its more compact effect via single device while receiving video and access wireless network data.
Fig. 1 represents wireless network accessing apparatus 11 of the present invention.As shown in the figure, (Access Point AP) 11 is applied to Radio Network System 12 to wireless network accessing apparatus, has the function of while receiving video and access wireless network data.
Radio Network System 12 comprises system's trunk 13 and mobile computer 14.Wireless network accessing apparatus 11 comprises video signal receiving terminal 21, demodulating unit 22, video decoding unit 23, the first Ethernet port 24, the second Ethernet port 25, processing unit 26 and audio-visual compression unit 27.
Wireless network accessing apparatus 11 is connected to video signal source 15 via video signal receiving terminal 21, to receive the video signal 16 that is transmitted by video signal source 15.According to different video signal sources 16 forms, video signal receiving terminal 21 can adopt coaxial cable terminations, S-Video terminal or A/V terminal.
For instance, video signal 16 is the television signal of NTSC form, what can remark additionally is herein, video signal receiving terminal 21 can be by the signal terminal of above-mentioned different size, be connected with various audio-visual devices, for example television set, Video CD player (DVD Player) or the like are to increase the diversity in image source.
What can remark additionally is herein, and video decoding unit 23 also can be connected directly to video signal receiving terminal 21 (not shown go out).At this moment, the video signal 16 that is transmitted by video signal receiving terminal 21 is directly deciphered in video decoding unit 23.
Audio-visual compression unit 27 is connected between video decoding unit 23 and the processing unit 26, after the digital video signal that is used for being transmitted by video decoding unit 23 is compressed with the MPEG technology, is resent to processing unit 26.
By being connected with the first Ethernet port 24, processing unit 26 can monitoring wireless network access device 11 and system's trunk 13 between these first data packets 18 and the reception and the transmission status of these second data packets 19, for example monitor the flow and the quality of these first data packets 18 and these second data packets 19.
At last, wireless network accessing apparatus 11 can adopt two kinds of different modes to share these video signal packages 17, these first data packets 18 and these second data packets 19 with mobile computer 14, is respectively the mode that adopts Wireless transmission mode and adopt wire transmission.
When wireless network accessing apparatus 11 adopts Wireless transmission mode, processing unit 26 can be according to the ICP/IP protocol that is applied to the internet, via antenna 20 with Video Streaming (Streaming Technology) with these video signal package 17 wireless mobile computers 14 that are sent to, therefore, the user 31 of mobile computer 14 can receive the video signal 16 of being sent out by video signal source 15 by wireless network accessing apparatus 11, appreciates the effect of TV programme to reach to use a computer.Simultaneously, processing unit 26 also passes through these first data packets 18 of antenna 20 wireless transmission to mobile computer 14, perhaps from these second data packets 19 of mobile computer 14 wireless receivings, therefore, the user 31 of mobile computer 14 can or transmit these first data packets 18 and these second data packets 19 by wireless network accessing apparatus 11 receptions, to reach the effect of the browsing internet that uses a computer.What can remark additionally is that antenna 20 is to handle these video signal packages 17, these first data packets 18 and these second data packets 19 according to IEEE 802.11x standard to transmit or receive operation herein.
When wireless network accessing apparatus 11 adopts the mode of wire transmission, processing unit 26 can be according to the ICP/IP protocol that is applied to the internet, transmit these video signal packages 17 and these first data packets 18 to mobile computer 14 via the second Ethernet port 25, perhaps receive these second data packets 19, make the user 31 of mobile computer 14 can use a computer equally and reach the effect of appreciating TV programme and browsing internet from mobile computer 14.Again, the second Ethernet port 25 is the RJ45 link.
As mentioned above, mobile computer 14 is with after wireless network accessing apparatus 11 links to each other, and user 31 also can appreciate TV programme simultaneously except can surfing the Net.Moreover wireless network accessing apparatus 11 is if adopt Wireless transmission mode to link to each other with mobile computer 14, and then in certain zone, user 31 does not need to move to by the television set, appreciates the enjoyment of TV programme while can enjoy to get online without being tethered to a cable.
Wireless network accessing apparatus of the present invention more adds the function of image processing outside general wireless networking capabilities.By this, the user can not only improve elasticity and convenience on using significantly via single device simultaneously receiving video and access wireless network data, more compact effect after having more electronic product and integrating.
Though the present invention discloses as above with preferred embodiment; so it is not in order to limit scope of the present invention; anyly have the knack of this skill person; without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking accompanying the claim person of defining.
