Abstract: A video encoder and a decoder analyze the spatial content video data in an H.264 stream using the discrete cosine transform (DCT). Although the DCT is computed as part of the H.264 encoding process, it is not computed as part of the decoding process. Thus, one would compute the DCT of the video data after it has been reconstructed by the video decoder for video post-processing or enhanced video encoding. A method for accelerating the computation of the DCT at the decoder side when transmitting intra-mode macroblocks uses information computed by the encoder and transmitted as part of the H.264 video stream.

Abstract: A signature that can be used to identify video content in a series of video frames is generated by first calculating the average and variance of picture elements in a low-resolution composite image that represents a temporal and spatial composite of the video content in the series of frames. The signature is generated by applying a hash function to values derived from the average and variance composite representations. The video content of a signal can be represented by a set of signatures that are generated for multiple series of frames within the signal. A set of signatures can provide reliable identifications despite intentional and unintentional modifications to the content.

Abstract: A single composite stream of data is streamed to a user's terminal and displayed in two separate viewers. This composite stream embeds a series of substreams that are views of the same event, taken from different point of views. A first viewer, the global viewer, displays the entire composite stream of data, thus displays the n substreams the composite stream may contain. The second viewer, the focus viewer, displays only part of the composite stream in order to display the substream currently selected by the user. While the stream is played back, the user may interact with an external application's user interface to select which of the n embedded streams he wants to be displayed in the focus viewer, thus creating a cut. The series of cuts created by the user is stored internally for playback management. The user may export the series of cuts he created in an editing file (EDL formatted, for instance, without being restricted to) that can be loaded into a professional editing application.
