摘要： An audio and video synchronization apparatus and method in a wireless communication network are provided. The audio and video synchronization apparatus includes a receiver that receives audio frames and video frames, a playback buffer that sequentially buffers the audio frames, a detector that determines whether the audio frames are synchronized with the video frames and adjusts a playback time of the video frames based on a playback time of the audio frames if it is determined the audio frames are not synchronized with the video frames.
摘要翻译：提供了一种无线通信网络中的音视频同步装置和方法。音频和视频同步装置包括接收音频帧和视频帧的接收机，顺序缓冲音频帧的重放缓冲器，确定音频帧是否与视频帧同步并且调整视频帧的重放时间的检测器如果确定音频帧不与视频帧同步，则基于音频帧的播放时间。

摘要： A method of performing an intra prediction coding with respect to a plurality of blocks included in an image frame is provided. The method of performing an intra prediction coding includes confirming whether a neighboring pixel that is referred to in an intra prediction of a block exists in the current frame, if the neighboring pixel referred to in the intra prediction exists, reading the color difference signal value of the pixel referred to in the intra prediction from the current image frame, if at least one neighboring pixel referred to in the intra prediction does not exist, reading the color difference signal value of at least one pixel from the previous image frame and performing the intra prediction with reference to the read color difference signal value of the pixel.
摘要翻译：提供了对包括在图像帧中的多个块执行帧内预测编码的方法。执行帧内预测编码的方法包括：如果存在帧内预测中涉及的相邻像素，则确认在当前帧中是否存在块的帧内预测中参照的相邻像素，读取帧内预测中的色差信号值如果在帧内预测中所参照的至少一个相邻像素不存在，则从当前图像帧在帧内预测中参照的像素从前一图像帧读取至少一个像素的色差信号值，参照该像素的读取色差信号值进行预测。
