Abstract: Methods and apparatus for control of data and content protection mechanisms across a network using a download delivery paradigm. In one embodiment, conditional access (CA), digital rights management (DRM), and trusted domain (TD) security policies are delivered, configured and enforced with respect to consumer premises equipment (CPE) within a cable television network. A trusted domain is established within the user's premises within which content access, distribution, and reproduction can be controlled remotely by the network operator. The content may be distributed to secure or non-secure “output” domains consistent with the security policies enforced by secure CA, DRM, and TD clients running within the trusted domain. Legacy and retail CPE models are also supported.

Abstract: Apparatus and methods for multiplexing data received from a plurality of sources to a communication channel. Each of the sources is assigned to one of at least two scheduling layers based in part upon one or more bit rate characteristics of the sources.

Abstract: A method and apparatus for non-seamless splicing of audio-video transport streams configured in accordance with MPEG-2 or other suitable techniques. A first transport stream is to be spliced with a second transport stream at a splice point. The first stream is configured such that the final first stream frame to be displayed will be a black frame or will have another suitable characteristic. Null packets are then delivered in place of the first stream transport packets for a predetermined period of time after the splice point. The predetermined time is generally greater than the sum of the splice decoding delay associated with the splice point and the maximum frame duration in the first stream. The transport packets of the second stream are then delivered. Null packets may be again delivered for a period of time sufficient to allow the final frame of the second stream to be displayed.
