The Digital Video Transition

Now that the Government has finally mandated and implemented the conversion from analog video to digital video, the security industry is finally going to progress at warp speed in unleashing a storm of new and exciting, and yes user-friendly, products that take full advantage of this technology. There is zero reason to be even thinking Analog anymore! Analog video has served us well but it is time to move on! Personally, I thought that by now the industry would be much further along the digital path that it has.

MPEG H.264/AVC is the latest and greatest compression technology. The purpose of H.264/AVC is to create a new standard which is capable of providing good quality (D1) performance at much lower bit rates that the previous standards. This new standard uses half or less the bit rate of MPEG-2, H.263, or MPEG-4 Part 2. The nice thing about H.264 from the technical standpoint is that it doesn’t increase the complexity of the design very much and it will not be overly expensive to implement from both the hardware and software sides if the isle. An additional and very important aspect of H.264 is the fact that will provide enough flexibility that will allow it to be used in a variety of network applications with the ability to scale both high and low bit rates depending on the application. Both the Blu-ray Disc format and the now-discontinued HD-DVD format include the H.264/AVC high profile as one of 3 mandatory video compression codecs. Sony has also chosen this format for their memory stick video format.
