Abstract
A video scaling apparatus includes a receiver for receiving incoming video signals having transmitted therein a plurality of incoming frames, each incoming frame having a first plurality of synchronization signals for indicating lines in the incoming frame; a scaler with a line extender for generating outgoing video signals having transmitted therein a plurality of outgoing frames, each outgoing frame having a second plurality of synchronization signals for indicating lines in the outgoing frame, and for generating an outgoing frame for each incoming frame. The line extender ensures durations of all lines in the outgoing video signals are of substantially equal length. By ensuring that all lines in the outgoing frame are of substantially the same length, the reliability of a display device receiving the outgoing video signals is increased. Additionally, the frequency requirements of an outgoing clock for the video signals can be less stringent.
