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.
