    摘要: A method for performing motion compensated video spatial up-conversion on video. The horizontal samples in successive fields are first interpolated using a spatial interpolation technique. This is followed by interpolating the corresponding vertical samples using a motion compensated deinterlacing technique. Such techniques can include an adaptively recursive motion compensated video spatial up-conversion or an adaptively recursive motion compensated video spatial up-conversion using a generalized sampling theorem. The present invention can be used to convert video captured on a mobile device, such as a mobile telephone, so that it can be subsequently and adequately displayed on a television.

    摘要: A decoder and method for using a new picture or frame type is provided. This type is referred to a an SP-picture. The temporal redundancies are not exploited in I-frames, compression efficiency of I-frame coding is significantly lower than the predictive coding. A method allows use of motion compensated predictive coding to exploit temporal redundancy in the sequence while still allowing perfect reconstruction of the frame using different reference frames. Methods using this new picture type provide for error resilience/recovery, bandwidth scalability, bitstream switching, processing scalability, random access and other functions. The SP-type picture provides for, among other functions, switching between different bitstreams, random access, fast forward and fast error-recovery by replacing I-pictures to increase the coding efficiency. As will be demonstrated, SP-pictures have the property that identical SP-frames may be obtained even when they are predicted using different reference frames.

    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 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: The present invention relates to a method for transmitting video information, in which a bitstream is formed comprising a set of frames comprising macroblocks. At least one switching frame is formed into the bitstream, macroblocks of the switching frame are arranged into a first and a second group of macroblocks, each macroblock of the first group of macroblocks are encoded by a first encoding method to provide a switching point for continuing the transmission of video information with another bitstream formed from the video information; and macroblocks of the second group of macroblocks are encoded by another encoding method. Errors in transmission of video information are reduced by forming at least one SP-encoded frame by predictively encoding the macroblocks; replacing part of the SP-encoded macroblocks with intra encoded blocks; and transmitting the encoded frame containing both predictively and intra encoded macroblocks instead of the SP-encoded frame.

    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: 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: A method for transmitting video information is shown, in which at least a first bit-stream (510) and a second bit-stream are formed. The first bit-stream (510) includes a video frame, and the second bit-stream (520) includes a predictive video frame (524). Different encoding parameters are used with encoding of the frames of the first bit-stream (510) and the second bit-stream (520). A frame of the first bit-stream (510) is transmitted, and the transmission is switched over from the first (510) to the second bit-stream (520) during which a secondary switching frame (550) is transmitted encoded using the encoding parameters of the second bit-stream (520) and at least one reference frame from the first bit-stream (510). The secondary switching frame (550) is used as a reference frame in the reconstruction of the predictive video frame (524) of the second set of video frames.
