Abstract
Fast channel change systems and methods are operable to change channels to a newly selected media content event in response to a user request. An exemplary embodiment communicates a previously stored low resolution version segment of the newly selected media content event to a presentation system while the media device is performing a tuning operation to change channels to receive a currently broadcasting high resolution version of the newly selected media content event. Once the tuning process has been completed at the media device, a handshake process is performed wherein the media device transitions presentation from the low resolution version to the high resolution version of the newly selected media content event.
