A video encoder and method are disclosed, the encoder for receiving high-resolution video and providing compressed high-resolution scalable and standard-resolution bitstreams, and including a standard-resolution encoder, a selector coupled with the standard-resolution encoder for selecting between a signal indicative of the received high-resolution sequence and a signal indicative of a standard-resolution version of the received sequence, and a high-resolution encoder coupled with the selector for providing a high-resolution scalable bitstream.
