Abstract
Systems, devices and methods are provided to support efficient and secure delivery of a media stream or content file to a mobile phone, tablet, computer or other remote device. Most of the media stream's content is received directly from a content source for efficient bandwidth allocation, but at least a portion of the stream is delivered from a set top box, television receiver, or other home device that is located at the customer's premises to preserve the security of the stream. The portion that is delivered from the home device may be a key portion of the stream that is essential to the playback of media stream.
