Patent ID: 7983440

Claim:
A method comprising: generating a compressed video stream including an Intra-Frame (I-Frame) and a plurality of associated frames referencing the I-Frame; generating a watermarked I-Frame corresponding to the I-Frame in the compressed video stream that is watermarked with a sample watermark similar to an actual watermark to be used for client-side watermarking; encoding the plurality of associated frames referencing the I-Frame based on the watermarked I-Frame to provide a plurality of encoded video frames; decoding the plurality of associated frames referencing the I-Frame based on the watermarked I-Frame to provide a plurality of decoded video frames; comparing the decoded plurality of associated frames referencing the I-Frame based on the watermarked I-Frame with raw digital video input to determine an error; and determining whether to select the I-Frame as an I-Frame to be used for client-side watermarking based on the comparison.
