Abstract:
A digital video decoder comprising:a terminal for receiving an encoded video signal; decoding circuitry which operates in a first mode to decode the received encoded video signal to provide a decoded video signal having a first spatial resolution and which operates in a second mode to provide the decoded video signal having a second spatial resolution which is less than the first spatial resolution; formatting circuitry including a spatial filter that, when the decoding circuitry operates in the second mode, is responsive to a formatting control signal to process the decoded video signal to change the spatial resolution of the decoded video signal to produce a filtered video portion as at least one display video signal at a respective output port and with a respective display format and having a respective display spatial resolution, different from the first and second spatial resolutions, and means for providing the video portion as at least one display video signal at a respective output port and with a respective display format; control means for switching the decoder between the first and second modes and for providing the formatting control signal to the formatting circuitry.
