Patent ID: 8773469

Claim:
A video multiviewer system comprising: a plurality of video scalers operating in parallel for generating initially scaled video streams of a plurality of received video input streams and corresponding metadata by performing video scaling in at least one dimension on the plurality of received video input streams based upon an initial scaling ratio; at least one video cross-point switcher coupled downstream from said plurality of video scalers; a processing unit coupled downstream from said at least one video cross-point switcher configured to: receive the initially scaled video streams and the corresponding metadata; and generate additionally scaled video streams by performing additional video scaling on the initially scaled video streams, said processing unit performing the additional scaling on the initially scaled video streams in cooperation with said plurality of video scalers and based upon the initial scaling ratio; said plurality of video scalers and said processing unit communicating through said at least one video cross-point switcher using a serial digital interface; and wherein the initial scaling ratio is selected based on the bandwidth allocated for the corresponding metadata from bandwidth of the serial digital interface.
