Abstract: Disclosed is a wireless transceiver system including an image transmitting apparatus and an image receiving apparatus. The image receiving apparatus includes a receiving antenna having a head direction set for each received beam and a control unit that measures one or more of received signal strength, bit error rate, and signal to noise ratio for each received beam and tracks a receiving beam direction so as to track the received beam and create head tracking information.

Abstract: Disclosed are a separation control video system in which a mobile terminal and an HMD device are independently separated from each other to control a direction of the image and an operating method thereof. The HMD device senses a spatial recognition data through a spatial sensor and transmits an image control data calculated based on the spatial recognition data to the mobile terminal and the mobile terminal extracts a controlled image corresponding to the image control data from an original image and transmits the controlled image to the HMD device.

Abstract: Disclosed is a non-protocol wireless interface apparatus for transmitting video and voice signals from a smart device to a display device over a high-speed wireless channel by uncompressed technique without using a complex wireless transport protocol, regardless of interface standards such as MHL or MyDP, etc., wherein the apparatus comprises a first broadband wireless adapter connected to a wired connection terminal of the smart device, and a second broadband wireless adapter connected to a wired connection terminal of the display device.
