Abstract:
Systems and methods for switching between encoded media streams are disclosed. A system may be configured to receive at least two media streams of differing qualities that are associated with an identical media asset. The system can seamlessly switch between a first media stream and a second media stream using an algorithm that can determine which frames of a second stream must be discarded to sync the second stream with the first media stream. The two media streams can then be cross faded to switch from the first media stream to the second media stream.
