TH26166B - Device encoding / decoding fields and predefined polarity field methods - Google Patents

Abstract

Movies are encoded into groups of framed video footage. Each frame contains a field. Of different polarity fields That are included to Predefined polarity fields First Field Polarity Of a series of frames that are encoded as the corresponding group of images to be set as a polar field. Preset In a nutshell, the polarity of the first field of the frame series is indicated by Information that is transmitted with encrypted movies The encoded movies will be decoded at the start time. The decryption was stated. When one of the fields in the image group corresponds to a predefined polarity field, in turn, when the decoding start time is determined step by step on the field defined data. First Field Polarity A computer readable medium provides a movie medium that is Encoded to be saved And will send the computer to decode the movie that was encoded when the first picture In the corresponding image group, it is an encoded field of a predefined polarity field, or vice versa, when the intermediate read field is the first one in the specified image. By the information given
