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.

摘要： A system and method are provided for selecting frames of a compressed video stream that may be used for client-side watermarking. In general, a content source evaluates a number of Intra-Frames (I-Frames) in the compressed video stream using a sample watermark that is similar to actual watermarks that may be used for client-side watermarking. More specifically, each of a number of I-Frames in the compressed video stream is evaluated by first watermarking the I-Frame with the sample watermark. Associated frames in the compressed video stream are then decoded using the watermarked I-Frame. An error value for the decoded video frames is then computed. If the error value is outside of a predetermined error threshold range, the I-Frame is selected as an I-Frame that may be used for client-side watermarking.

摘要： To help ensure that only authorized media content that is associated with rights management (RM) restrictions is delivered from a compliant RM interface of a source device to a non-compliant RM interface of a destination device, an interconnect device provides a compliant RM interface to connect to the source device and monitors media content received from the source device to detect an embedded digital watermark. The interconnect device takes the necessary steps to determine if the watermark is authentic and control delivery of the media content to the destination device accordingly. The interconnect device may go back to the source device or to a remote service to authenticate the watermark. If the watermark is authentic, the media content is passed by the interconnect device to the non-compliant interface of the destination device outside of normal RM restrictions. Otherwise, the delivery of the media content is restricted by the interconnect device.

摘要： An interconnect device receives encrypted high quality media content from a protected interface of the source device and decrypts the encrypted high quality media content to recover the high quality media content. For remote monitoring, the decrypted high quality media content is processed to reduce the quality of the high quality media content to generate the reduced quality media content. The reduced quality media content may be generated by further compressing the high quality media content, reducing the resolution of the high quality media content, downscaling the high quality media content or the like. The decrypted high quality media content is also re-encrypted and delivered to the protected media interface of the destination device.
