Abrégé
(EN)
The invention discloses a picture watermark adding method. The method comprises the following steps: decoding, by a source video stream into an original video format to obtain a decoded video stream;sending, by the decoder, video header information, slice header information and macro block information decoded by the source video stream to an encoder; superposing a picture watermark to a predetermined area in the decoded video stream to obtain a watermarked video stream; receiving, by the encoder, the video header information, the slice header information and the macro block information; and encoding, by the encoder, the video header information, the slice header information and the macro block information. The invention further provides an electronic device and a computer readable storagemedium. By adoption of the picture watermark adding method, the electronic device and the computer readable storage medium provided by the invention, the consistency of the encoded video and the original video can be ensured as much as possible after the watermark is added, and meanwhile the image quality of the output video can be improved.
