    摘要: A method and apparatus for controlling a link margin are provided. The method includes: receiving, from a second device, a link margin frame including information about the link margin related to a communication link between a first device and the second device; and performing at least one operation selected from among a change in transmission power, a change in a modulation and coding scheme (MCS), beam forming, and a change of the communication link to another frequency band, based on the received link margin frame.

    摘要: Methods and apparatuses for generating video packets are provided. A method of generating a video packet includes generating at least one pixel block including at least one reference pixel and at least one neighboring pixel adjacent to the at least one reference pixel from pixels of a video frame; replacing a pixel value of the at least one neighboring pixel in the at least one pixel block with a pixel difference value, which is a difference value between a pixel value of a pixel adjacent to the at least one neighboring pixel and the pixel value of the at least one neighboring pixel; and generating packets so that a pixel value of the at least one reference pixel and the pixel difference value of the at least one neighboring pixel are allocated to different packets according to positions of the pixels.

    摘要: A method and apparatus for generating video packets and a method and apparatus for restoring video are provided. The method of generating video packets includes: generating at least one pixel block consisting of at least one reference pixel and a plurality of neighboring pixels adjacent to the at least one reference pixel from pixels of a video frame; replacing pixel values of the neighboring pixels in the at least one pixel block with pixel difference values, which are difference values between a pixel value of one of pixels adjacent to the neighboring pixels and the pixel values of the neighboring pixels; generating packets so that a pixel value of the at least one reference pixel and the pixel difference values of the neighboring pixels are allocated to different packets according to positions of the pixels; and performing entropy coding of some of the packets including the pixel difference values of the neighboring pixels.
