摘要： An adaptive digital video signal processing apparatus and method for Y/C separation. In the video signal processing apparatus, an adaptive 2D BPF carries out Y/C separation through comb filtering and bandpass filtering selected according to local characteristics of an image (e.g., based on the direction in which an edge in the image extends in vertical and horizontal directions. The adaptive 2D BPF performs 2D bandpass filtering in general case. The 2D BPF adaptively executes a series of selections of the various filtering operations in a continuous manner.

摘要： For spatial resolution conversion of an image signal, a magnitude of a motion vector is compared to a threshold value. Single channel interpolation is performed if the magnitude of the motion vector is greater than a threshold value, and multi-channel interpolation is performed otherwise. In addition, single channel interpolation is performed for spatial resolution conversion of any frame that does not refer to another frame.

摘要： An apparatus and method of controlling a digital video (MPEG) player for reverse-play. The MPEG player is comprised of an I-frame buffer for storing I-pictures encoded from P-pictures by a video decoder, a B-frame buffer for storing B-pictures, and an I-frame encoder for decoding a P-picture into an I-picture. In the MPEG player, a picture group being played at present is decoded for reverse play and a previous picture group is decoded for preparation of the reverse-play. Reverse-play in soft 1-times (×1) by means of a frame memory of small capacity is achieved irrespective of the picture number and classes in picture groups.
