  • Patent number: 9560311
    Abstract: A processor converts an input video signal via a first filter, and outputs a video signal for a determination obtained by converting the video signal via a second filter. Both filters satisfy a stipulated condition. The processor calculates the degree of matching between the input video signal and the video signal for the determination. The processor determines whether or not the input video signal has been converted by using a filter that satisfies the stipulated condition in conversion at a preceding stage. The processor generates an encoded string by encoding the video signal in the second format converted via the first filter, and the determination result. In this way, whether or not and where a video is that converted by using a filter different from a stipulated filter can be automatically determined.
