Abstract: Apparatus and methods for recording a media stream for use by a rendering device. In one embodiment, a client device records live, unbound streaming media content from a Content Delivery Network (CDN) in “chunks” according to a data structure such as a manifest file. The live media content stream chunks are compressed and stored for later playback. The client device uses information regarding the chunks to generate a local manifest file, which it then uses to reconstruct the media stream. A video client may also dynamically insert and account for updated secondary content (such as advertisements) during each playback instance, thus enabling the service provider to realize commercial opportunities which were previously not possible. Various operational/business rules are also disclosed for e.g., enabling and disabling functions with respect to playback of the content.

Abstract: Methods and apparatus for providing delivery of content to client devices of a network via both multicast and unicast mechanisms. In one embodiment, a system for use in a managed content delivery network is described to bridge multicast to unicast, so that the total network bandwidth consumption is significantly lower than a corresponding unicast-only delivery solution, yet which still provides improved quality of service and user viewing experience as compared to a multicast-only delivery solution. In addition, various exemplary aspects of the present disclosure are readily adapted for real-time multicast to unicast streaming of audio and data to, among other things, minimize network bandwidth usage, while maintaining the guaranteed delivery of unicast streams with little or no modification to the existing client device logic.

Abstract: Methods and apparatus for delivering data over extant infrastructure within a content-based network. In one embodiment, the network comprises a cable network, and the infrastructure comprises that nominally used for on-demand (OD) services such as VOD. The method includes the allocation of dedicated end-to-end network resources via a “session request, as well as data flow control and packet size adaptation, by a data server based on feedback from the requesting/receiving client device (e.g., DSTB) within the network. Mechanisms for retransmission requests for error recovery are also provided.
