摘要： When a standard TV signal of digital format is a first video signal and another digitized TV signal having a bandwidth wider than that of the first video signal is a second video signal, every two frames of the second video signal are calculated to produce a pixel value sum of the two frames and a pixel value difference between the same and either a resultant interframe calculated output or the first video signal is compressed through two-dimensional orthogonal transformation for ease of storage.

摘要： In digital video signals which differ in the number of pixels thereof, such as a standard video signal having a screen aspect ratio of 4:3 and a wide video signal having an aspect ratio of 16:9 the data quantity after encoding is equalized without increasing the compression ratio of the video signal having the larger number of pixels. An encoding apparatus performs intraframe encoding of the standard video signal so that the coded data quantity is constant in every frame, and interframe encoding of the wide video signal in each two frames so that the coded data quantity is constant in every two frames.

摘要： The present invention includes a motion vector detector for detecting motion vectors using a first image signal of high resolution; a resolution reducer for creating a second image signal of low resolution from the first image signal; an image signal interpolater for interpolating the second image signal so that it has the same number of pixels as the first image signal, thereby creating an interpolated signal; a differentiator for determining a differential between the first image signal and the interpolated signal; and an encoder for using the motion vectors to high-efficiency-encode the differential signal. Thus, by encoding two types of image signals of different resolutions, the present invention improves the accuracy of the motion vectors during the encoding of the high-resolution signal and reduces the rate after encoding due to the encoding of the differential signal.
