CLIENT-SIDE WATERMARKING USING HYBRID I-FRAMES |
摘要 |
A system and method for client-side watermarking of digital content using hybrid Intra-Frames (I-Frames) are provided. In general, a content source provides a compressed video stream and a hybrid I-Frame stream to a client device via a network. The hybrid I-Frame stream includes a number of low-loss I-Frames corresponding to select ones of the I-Frames in the compressed video stream to be used for client-side watermarking. The client device watermarks the I-Frames in the hybrid I-Frame stream, optionally compresses the watermarked I-Frames, and replaces the select ones of the I-Frames in the compressed video stream with the watermarked and optionally compressed I-Frames to provide a watermarked version of the compressed video stream.
