The book by Charles Poynton (2012), Digital Video and HD Algorithms and Interfaces, Second Edition (Burlington, Mass.: Elsevier/Morgan Kaufmann) is now commercially available. The Table of Contents is available.
Much material concerning analog video, NTSC, and PAL has been retired to make room for the new, relevant stuff. The retired material forms a forthcoming web book, Composite NTSC and PAL: Legacy Video Systems, that (once finished) will be freely available here.
Information about the first edition of Digital Video and HDTV Algorithms and Interfaces remains available.
