Jaggies is the informal name of an artifact caused by poor de-interlacing and/or scaling. Visually, jaggies look like jagged stair-steps where there should be a smooth diagonal line. The better the scaler, be in in a TV, Blu-ray player, or AV Receiver, the less noticeable the jaggies.
Notable scaling companies that do an excellent job minimizing jaggies are DVDO (Anchor Bay), Silicon Optix, Marvell, and Faroudja.
