摘要： When a video stream is edited in compressed domain to achieve video editing effects, the edited bitstream may violate the receiver buffer fullness requirement. In order to comply with the buffer fullness requirement, buffer parameters in the bitstream and the file format are adjusted to ensure that the buffer will not become underflow or overflow due to video editing. As such, re-encoding the entire bitstream is not needed. If the editing effect is a slow-motion effect, a fast motion effect or a black-and-white effect, the buffer parameter to be adjusted can be the transmission rate. If the editing effect is a black-and-white effect, a cutting effect, a merging effect or a fading effect, the compressed frame sized can be adjusted.
摘要翻译： 当视频流在压缩域中编辑以实现视频编辑效果时，编辑的比特流可能违反接收缓冲区满足要求。 为了符合缓冲区满足要求，调整比特流中的缓冲区参数和文件格式，以确保缓冲区不会由于视频编辑而下溢或溢出。 因此，不需要重新编码整个比特流。 如果编辑效果是慢动作效果，快速运动效果或黑白效果，则要调整的缓冲参数可以是传输速率。 如果编辑效果是黑白效果，切割效果，合并效果或衰落效果，则可以调整压缩帧尺寸。

摘要： A method and device for editing a video sequence while the sequence is in a compressed format. In order to achieve a video effect, editing data indicative of the video effect is applied to residual data from a compressed bitstream. The residual data can be residual error data, transformed residual error data, quantized transformed residual error data or coded, quantized, transformed residual error data. The video effects include fading-in to a color or to a set of colors, fading-out from a color or a set of color, or fading-in from color components in color video frames to color components in monochrome video frames. The editing operations can be multiplication or addition or both.

摘要： A method and device for editing video data to achieve a video effect in a video sequence. From an encoder, transform coefficients of part of the video sequence are obtained. The transform coefficients are mixed with other transform coefficients in a combining module. The output of the combining module is quantized and further processed to provide an edited video bitstream. In the combining module, transform coefficients are multiplied with weighting parameters to achieve different video effects. Furthermore, logo data from a memory can be transformed into further transform coefficients for mixing in order to achieve a logo insertion effect. Moreover, prediction error and motion compensation information obtained from video data can be used to provide a reference frame, and the transform data from the reference frame can be used for mixing to achieve a blending effect.

摘要： A method and system for allowing a client to carry out image surfing. After connecting with a server, the client can select an image category of images to surf from. Upon request by the client, the server sends a set of thumbnails of images to the client, allowing the client to specify one of them for surfing. The client has a GUI interface by which the client can move a selection box to select a portion of the specified image for viewing. If the client wishes to zoom in, zoom out, or enhance the quality of the viewed area, the client sends a request to the server so that the server can send the client the necessary image sub-component to achieve the zoomed or enhanced image portion.

摘要： A method for detecting scene changes in a video sequence in the compressed domain. DC images are extracted from the macroblocks of the video frames. Histogram differences and pixel difference of the DC images are used for scene cut detection, and the changes in the histogram differences are used for gradual scene change detection. Thus, scene cut detection is based on first order derivatives of the histogram and gradual scene change detection is based on second order derivatives of the histogram. If the macroblocks are intra-coded, they are used to compute the exact DC images. If the macroblocks are not intra-coded, motion information in the frame is partially used for scene change detection.
