    摘要: A scalable coder having a grid motion estimation and compensation module (110), a motion compensation temporal filtering module (105), a scalable coding module (115), a discrete transformation module (120), and a packetization module (135). The grid-motion estimation and compensation module (110) outputs a scalable motion vector from the source video data, supplied resolution and bit rate parameters. The motion compensation temporal filtering module (105) generates, from the source video data and the scalable motion vector, a residual image corresponding to the difference between the present and previous image frames. The scalable coding module (115) is coupled to receive and encode the scalable motion vector. The discrete transformation module (120) is configured to receive and domain transform the supplied video to a sequence of coefficients. The packetization module is coupled to the scalable coding module (115) and the discrete transformation module (120), and is operable to combine the encoded scalable motion vector and the sequence of coefficients into a packet.

    摘要: A method (400) and an apparatus for AVC intra prediction to code digital video comprising a plurality of pictures are disclosed. The method comprises the steps of: generating (410) edge directional information for each intra block of a digital picture; and choosing (420) most probable intra prediction modes for rate distortion optimisation dependent upon the generated edge directional information. The edge directional information may be generated by applying at least one edge operator to the digital picture. The edge direction histogram may sum up the amplitudes of pixels with similar 15 directions in the block. The method may further comprise the step of intra coding (430) a block of the digital picture using the chosen most probable intra prediction modes.
