AVC-I: Yet Another Intra Codec for Broadcast Contribution?

Large availability of fiber and high-speed IP networks now enable the use of intra video codecs in a wide range of contribution application. Such formats permit low end-to-end delays and are easily editable. In addition, their reduced complexity allows a significant equipment cost reduction over Long GOP equivalents. These well-known advantages have paved the way for a variety of proprietary and standardized solutions like VC-2, VC-3 or JPEG-2K. — AVC-I is simply an MPEG-4 AVC / H.264 profile obtained by capping complexity and removing encoding tools from the standard's broadcast contribution profiles. This simple conception is the promise of a straight-forward compatibility between equipments from various vendors. But it remains to be seen, beyond academic research, if actual AVC-I products are able to meet and exceed the quality levels and the operational advantages of intra codecs currently in use.
