AVC-ULTRA Overview, rev 2.0 2 Introduction H.264/AVC video codec was adopted by Panasonic in 2007 as “AVC - Intra”, the first production format using H.264/AVC for professional applications. Since then, all P2-HD product lines have been equipped as standard with AVC-Intra. AVC-Intra provides excellent picture quality with higher compression efficiency and the potential bit rate saving by AVC-Intra is around 50% over the conventional codec schemes. AVC-Intra employs the Intra-only and frame completed codec scheme suitable for editing. These features have been accepted by the industry and AVC-Intra has been recognized as one of the standard formats for non-liner editing and server systems. Peripheral equipment and a variety of tools supporting AVC-intra have been produced and now more than 45 vendors support AVC-Intra and more than 90 products supporting AVC-Intra are available. Given the situation above, six years behind Panasonic, other major camera manufacturers have started to introduce video codec using H.264/AVC based on the similar concept. A couple of years after AVC-Intra was introduced to the market, evolutions in network infrastructures and semiconductor technologies has created new innovations in viewing environments of image contents and production workflow. The recent growth of mobile devices has been boosting the performance of public network, improving the network speed by about ten times faster than in the past. This enables customers to review image contents not only by conventional television broadcasting but also by more versatile ways such as using a smart phone or a tablet device. In the image content creation business, a new workflow utilizing IP network transmissions and removing constraints on time and location is going to be feasible. The evolution of semiconductor technologies enables a large scale, high speed, and lower power consumption LSI, allowing the production of rich images with a higher resolution at a lower cost. Having seen the evolution of these technologies and the environment that has emerged over the past few years as an opportunity to establish a new stage of image production, Panasonic developed the AVC-ULTRA codec family by advancing the use of H.264/AVC technologies accumulated through the development of AVC-Intra. This paper discusses what AVC-ULTRA will bring to image production, gives an overview of the AVC-ULTRA codec scheme and the technologies supporting AVC-ULTRA implementations.
