What is Pitch ?

Sorry, if the problem sounds trivial.

After a while, I still don't have a clear understanding on this term used in DSP.

For example, pitch should be x64 in VLIB. For input 720*480, I always patch the frame to 768*480 and set pitch = width = 768, then I can get some nice result.

Could anyone give some insight or recommend something to read?

Thanks a lot

    If you can refer SPRUER9D, figure 6 and 7 depict frame width, height and pitch( referred as address offset value for each line in the document) clearly.
