    • A method of performing hand-over in a personal basic service set (PBSS) including a plurality of stations and one coordinator is provided. An association request frame comprising PCP capability information, and requesting to associate to the PBSS, is received from each of the stations. The PCP capability information comprises information regarding at least one of whether each of the stations supports a power source capability of continuous power supply, whether each of the stations supports a channel time allocation function, and whether each of the stations supports a network clustering function. An association response frame, indicating whether the association request received from each of the stations is approved, is transmitted to each of the stations, and a priority to be a coordinator of the stations is determined based on the PCP capability information. Hand-over is performed with one of the stations according to the determined priority.
    • 提供了一种在包括多个站和一个协调器的个人基本服务集(PBSS)中执行切换的方法。 从每个站接收包括PCP能力信息并请求与PBSS相关联的关联请求帧。 PCP能力信息包括关于每个站是否支持连续电源的电源能力,每个站是否支持信道时间分配功能以及每个站是否支持网络聚类功能中的至少一个的信息。 指示从每个站接收的关联请求是否被批准的关联响应帧被发送到每个站,并且基于PCP能力信息来确定要成为站的协调器的优先级。 根据确定的优先级,其中一个站执行切换。

    • 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.
    • 提供了一种用于产生视频分组的方法和装置以及用于恢复视频的方法和装置。 产生视频分组的方法包括:从视频帧的像素生成由与至少一个参考像素相邻的至少一个参考像素和多个相邻像素组成的至少一个像素块; 用像素差值代替所述至少一个像素块中的相邻像素的像素值,所述像素差值是与相邻像素相邻的一个像素的像素值与相邻像素的像素值之间的差值; 生成分组,使得根据像素的位置将所述至少一个参考像素的像素值和相邻像素的像素差值分配给不同的分组; 并执行包括相邻像素的像素差值的一些分组的熵编码。
