  • Publication number: 20210224959
    Abstract: A method of image processing in wireless channel environment comprises steps of: dividing a frame of content image data into multiple blocks defined by a line; wirelessly transmitting the multiple blocks per line by coding channels in channel coding units by defining a transmission code rate according to a wireless channel environment information; determining whether there is a channel error for each block after decoding a received data; extracting an information of an image of an errored block; determining an image error correction method suitable for the extracted information; replacing the errored block with an error-corrected block according to the determined image correction method; and performing a post processing process to eliminate visual unnaturalness between the replaced block and a neighboring block at a block boundary.

  • Patent number: 10856039
    Abstract: Disclosed is method of transmitting wireless variable AV according to channel environment, the AV format, code rate, and modulation index based on the lookup table according to the data rate. The modulation index, AV format, code rate, and output level may be adjusted step by step based on an SNR and/or a BER to provide a high quality image according to a channel environment.

  • Publication number: 20180239419
    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.

  • Publication number: 20170147274
    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.
