Abstract: Techniques for packet-accurate targeted content substitution by a stitcher are described herein. In some embodiments, the stitcher at a client device receives a live transport stream (TS) and a splice message indicating a start time and an end time of a splice period. The stitcher locates in the live TS a video packet with a video packet identifier (PID) and an audio packet with an audio PID crossing the start time. The stitcher injects to the live TS targeted content TS packets within the splice period, where the injection includes re-stamping PIDs and presentation timestamps of the targeted content TS packets to match the live TS packets, and re-stamping the live TS packets with a predefined PID starting from the video packet and the audio packet, and ceasing the re-stamping when a respective audio packet in the live TS packets crossing the end time.

Abstract: Techniques for a trusted system for secure content distribution and trusted recording of content consumption are described. In some embodiments, the trusted system transcodes and transcrypts a media content item using a key obtained from a content provider and one or more keys based on an entitlement from a service provider to generate an encrypted media content item. The trusted system further receives a request to provide the media content item to a client device. The trusted system also obtains a signed audit token recording the request upon an authorization by the service provider based on the entitlement and a confirmation by the content provider, where the signed audit token is signed by the content provider and the service provider. The trusted system additionally provides the one or more keys for decrypting the encrypted media content item and reports the signed audit token.

Abstract: Cloud Digital Video Recorder (cDVR) storage reduction may be provided. First, a plurality of recording requests to record a content program may be received. Then a plurality of content data instances corresponding to the content program may be recorded by recording a content data instance for each of the plurality of recording requests. Next, a plurality of play-back requests corresponding to the content program may be received. Ones of the plurality of content data instances may be respectively provided in response to each of the plurality of play-back requests and then the ones of the plurality of content data instances may be respectively deleted in response to providing respectively the ones of the plurality of content data instance. In addition, other ones of the plurality of content data instances may be periodically deleted.
