摘要： When a pause request occurs, an audio delay time constituted by a delay time of frames of audio data based on the video data frames is found. During the pause, a frame offset time constituted by the offset of the frame start time of the video data and the audio data is monitored. When a pause release request is issued, based on the audio delay time and the frame offset time, the audio correction time to be corrected in the pause request is calculated. Then, when it is judged that the audio data is advanced with respect to the video data based on the audio correction time cumulatively added for each pause request, the video data is delayed by one frame with respect to the audio data, while when it is judged that the audio data is delayed with respect to the video data, the audio data is delayed by one frame with respect to the video data.

摘要： An image encoder and its processing method for compression-encoding a dynamic image at a variable encoding rate in the case of an application required to perform real-time processing. A variable bit rate (VBR) control section (22) determines a VBR control quantizing scale VBRq according to a VBR buffer value held in a VBR buffer recording section (21). A constant bit rate (CBR) control section (23) determines a CBR control quantizing scale CBRq according to an inputted maximum bit rate BRmax. A quantizing scale comparing section (25) outputs the CBRq during constant rate encoding and outputs the larger one of the VBRq and CBRq during variable rate encoding. An image compression-encoding section (24) encodes the inputted image signal at a quantizing scale outputted from the quantizing scale comparing section (25) and outputs a bit stream (S20).

摘要： A method and apparatus for preprocessing a video signal prior to its being encoded. During preprocessing, features are extracted from the video signal into feature planes which are each adaptively filtered in response to estimations of feature activity. After feature extraction the signal which remains is referred to as a “remaining signal”, which is then noise filtered to remove a substantial portion of the noise. The feature planes and remaining signal are recombined into a preprocessed output signal configured for receipt and processing by a video encoder. A video encoder receiving the preprocessed video signal can generate higher quality and/or lower bit rate encoded video than one receiving the original source video. Preprocessing according to the invention is particularly well suited for use with encoders adapted to remove temporal and/or spatial redundancy, such as those implemented according to the MPEG2/4, or AVC/H.264 standards.
摘要翻译：一种用于在编码视频信号之前对视频信号进行预处理的方法和装置。在预处理期间，将特征从视频信号提取到特征平面中，每个特征平面根据特征活动的估计被自适应过滤。在特征提取之后，剩下的信号被称为“剩余信号”，然后对其进行噪声滤波以去除大部分噪声。特征平面和剩余信号被重新组合成被配置为由视频编码器接收和处理的预处理输出信号。接收预处理视频信号的视频编码器可以产生比接收原始源视频的视频编码视频更高质量和/或较低比特率编码视频。根据本发明的预处理特别适合于适用于去除时间和/或空间冗余的编码器，诸如根据MPEG2 / 4或AVC / H.264标准实现的冗余。

摘要： A method of detecting existence of visually thin lines in images is described herein. The method includes profile generation, profile analysis and deciding the existence of thin lines. The profile generation includes generating a profile in each direction of the input image. Multiple projection lines are projected along the direction and all of the pixel values along the projection lines are added and averaged to obtain a profile. The profile analysis includes determining presence of thin lines in the input image and also noticing if the direction of the thin lines is similar to that of the projection lines. At the third step, according to the analysis made, existence of thin lines in the image is decided.
