20100321252Wireless chip and wireless device - The present invention discloses a wireless chip comprising a circuit layer above which a microstrip antenna is provided, and a wave-absorbing body is provided between the circuit layer and the microstrip antenna. Since the microstrip antenna is disposed above the circuit layer, the wave-absorbing body capable of absorbing energy is utilized to isolate the circuit from the antenna, and the metal film in the microstrip antenna functions not only as the RF ground of the antenna but also as a shield against any interference, it is possible to effectively address the problem of the antenna interfering with the circuit; by selecting the medium with suitable dielectric constant, the height of the chip can be prevented from being unduly increased, thereby ensuring that the chip and the wireless device using the same are both small in size. The present, invention also discloses the wireless device containing the wireless chip12-23-2010
20090006709PCI EXPRESS INTERFACE - The present invention discloses a PCI Express interface compatible with USB interface comprising a power supply terminal and a ground terminal, in which four data terminals include two data transmitting terminals and two data receiving terminals, characterized in that the power supply terminal and the ground terminal of said interface coincide with the corresponding terminals of USB interface specification, two of said four data terminals are guaranteed to have their positions and widths overlaid with the position of terminal D+ in USB interface specification and not with the position of terminal D− in USB interface specification, and the other two data terminals are guaranteed to have their positions and widths overlaid with the position of terminal D− in USB interface specification and not with the position of terminal D+ in USB interface specification. The PCI Express interface compatible with USB interface can provide a data transmission rate up to 3 Gb/S according to PCI Express interface specification and support to the conventional USB peripheral devices without any modification on them. It further has the advantages of small-sized outline and convenience in use.01-01-2009
20080301730Method and device for TV channel search - A TV channel search method and device is provided, wherein the method comprises (a) snatching screenshots of real time video signals of frequencies to generate snatched screenshots; (b) establishing and storing correspondence relationship of the snatched screenshots and frequencies; (c) providing the snatched screenshots for user selection and obtaining a snatched screenshot selected by the user; and (d) obtaining a frequency corresponding to the snatched screenshot selected by the user based on the correspondence relation of the snatched screenshots and frequencies, and then performing aimed TV channel switch and play. According to the method and device of the invention, the user can quickly and visually search a TV channel independent on EPG information after the correspondence relationship of images and frequencies has been established by snatching screenshots of real time TV pictures, and the method and device is applicable in both analog TV and digital TV.12-04-2008
20080270512Virtual network projection system supporting multiple projection sources and method thereof - A network projection system and method are disclosed, the system comprises announcement means for announcing virtual network projection device information over a network and receiving a projection request from at least one network projection source, projection data receiving means for receiving data used in projection from the at least one network projection source, processing means for processing the data received from the at least one network projection source to meet a user's requirement, and projection data displaying means for displaying the processed projection data on a connected display device or transmitting the processed projection data to another network projection device over the network. With the structure of the present invention, a common display device can be virtualized as a network projection device to facilitate simultaneous display of projection contents from multiple projection sources on the same screen or switching of display via the network.10-30-2008
20080263201METHOD FOR REAL-TIME MONITORING A REMOTE CONTROL PROCESS BY A THIRD PARTY AND SYSTEM THEREOF - The invention relates to a remote monitor technique. In particular, the present invention relates to a method for real-time monitoring a remote control process by a third party and a system thereof, which are able to third-party monitor a control terminal and a controlled terminal in the remote control process. The method comprises steps of establishing a connection between a control terminal and a third party monitoring terminal; arranging the control terminal, the controlled terminal and the third party monitoring terminal in one and the same session based on the connection; the controlled terminal sending its desktop video to the third party monitoring terminal via a virtual display driver; and the third party monitoring terminal sending a predetermined control strategy to the controlled terminal.10-23-2008
20080246835APPARATUS AND METHOD FOR TRANSFERRING VIDEO - The present invention discloses a terminal for transferring video, comprising an audio-video splitting/assembling unit for assembling locally acquired video stream and audio stream, or splitting an audio-video assembly sent from a counter-terminal into video stream and audio stream; a device discovering unit responsible for searching for a first device with video capturing and displaying functions; wherein the audio-video splitting/assembling unit is adapted to receive a video stream of images captured by the first device after the device discovering unit has found the first device, and then to use the video stream for the local audio-video assembly, or the audio-video splitting/assembling unit is adapted to send the split video stream to the first device for video display. Obviously, since the counter-party's picture is transferred to the first device with a larger screen, the display effect is improved, and it is possible to bring the user a better visual experience without the limitation of the size of the video terminal screen. The present invention further provides a method for transferring video.10-09-2008
20080244271METHOD AND SYSTEM FOR AUTHENTICATION BASED ON WIRELESS IDENTIFICATION, WIRELESS IDENTIFICATION AND SERVER - The invention discloses a method and a system for authentication based on a wireless identification, and a wireless identification. The method comprises steps of: obtaining, by a mobile device, wireless tag information and connection configuration information from the wireless identification; establishing, by the mobile device, a connection with the server according to the connection configuration information, and transmitting, by the mobile device, the wireless tag information to the server; authenticating, by the server, the validity of the wireless tag information, and determining, by the server, an access right of the mobile device after the authentication is successful; generating, by the wireless identification, device signature information and forwarding it, by the mobile device, to the server; and authenticating, by the server, the validity of the device signature information, and canceling, by the server, the access right of the mobile device. The present invention provides an authentication system based on the wireless identification, wherein the server authenticates not only the wireless tag information, but also the device signature information generated by the wireless identification, thereby the system is of a higher security.10-02-2008
