Abstract
A remote time shift buffer system with shadow tuning. The remote time shift buffer system includes a client in communication with a remote video recorder. The client tunes to a channel from a television signal source and sends the channel content to a television. When a channel change occurs at the client, the remote video recorder tunes to the same channel as the client and buffers the content. When a pause live television (PLTV) function is initiated, the remote video recorder generates an independent RTSB content stream using the buffered content. Once the RTSB content stream is available, the client switches inputs and displays the RTSB content stream from the remote video recorder. Manipulating the position within the RTSB content stream does not affect buffering of the live content. The remote time shift buffer system provides pause live television functionality with minimal loss of content.
