摘要： A method and system for associating metadata with an encrypted content item, the method including receiving metadata for association with a content item, receiving an entitlement control packet (ECP) associated with the content item, applying a cryptographic hash function to the ECP, thereby generating an ECP hash value, combining the ECP hash value with the metadata, thereby creating a data control object, performing a cryptographic operation on the data control object, thereby generating cryptographic integrity data, and joining the cryptographic integrity data to the data control object after the cryptographic operation, wherein usage of the content by the recipient is dependent on both a validation of the ECP hash value and a validation of the cryptographic integrity data. Related apparatus and methods are also described.

摘要： A video substitution method for use with a Digital Video Recorder (DVR) which is operative to store video is disclosed. The method includes retrieving stored video recorded from a single video stream which includes a first positive integer nl down-sampled video sequences, the nl down-sampled video sequences being mutually synchronized and formatted in a second positive integer n2 video frames, each video frame comprising nl spatially combined sub-pictures each of which corresponds to one frame of the nl down-sampled video sequences, up- sampling at least part of a first one of the nl down-sampled video sequences, thereby producing a first up-sampled video sequence, displaying the first up-sampled video sequence on a display during normal content viewing, detecting activation of a trick mode including one of the following: a fast forward mode; and a rewind mode, and in response to the detecting: up-sampling at least part of a second one of the nl down- sampled video sequences, thereby producing a second up-sampled video sequence, and displaying the second up-sampled video sequence instead of the first up-sampled video sequence during at least part of an activation period of the trick mode. Related apparatus and methods are also disclosed.
