Claim:
A method of selectively providing multimedia content to a content receiving device, the method comprising the steps of: receiving a plurality of source content streams with the same video content, each of the source content streams comprising an audio component and a video component, streaming output content comprising audio and video components to the content receiving device, the output content being derived from a first source content stream selected from the plurality of received source content streams; sampling the first source content stream to extract a frame sequence having audio and video components, and evaluating the functionality of the first source content stream from the extracted frame sequence, switching to a new source content stream selected from the plurality of received source content streams when the frame sequence is indicative of a streaming error, wherein a streaming error is determined when a level of audio for the audio component or a level of motion for the video component of the frame sequence is less than a corresponding predefined minimum threshold value; and synchronizing the frame rate derived from the new source content stream with the frame rate being streamed to the content receiving device.
