The evolution of JPEG2000 and a new visually lossless compression technology can move full Ultra-HDTV quality on limited bandwidths says Gaël Rouvroy, CTO, intoPIX
“I need to transfer higher resolutions without compromising the pristine quality. Is there a simple way to move to UHDTV with the uncompressed quality on limited bandwidth?” Yes. The evolution of
JPEG2000 compression with new profiles for UHDTV and additionally the launch of a new ultra-light disruptive, visually lossless compression technology at IBC by intoPIX are designed to answer this market challenge. With UHDTV, broadcasters
understand the importance of some key words: highest image quality, flexible delivery formats, interoperability, simplicity and affordability. The new HEVC /H.265 compression is promising for optimising the distribution of new essence, to deliver the customer on a pipe
with very limited bandwidth. For broadcasting, when no further editing is expected, long-GOP codec are always preferred. For cameras, production,
SMPTE2022 transmission, storage and archives, the need for JPEG2000 has gained significant attraction in the production workflow. Our industry has recently worked on new JPEG2000 profiles for UHDTV 4K and 8K, Cinema High Frames Rates, IMF and broadcast contribution. JPEG 2000 brings features that give the user superior control and flexibility of the image processing chain. The codec requires less
power, less space in hardware implementations and generally delivers greater scalability, flexibility and visual quality than any other codec. Intra-frame by its very nature, the codec
closely matches the production workflow in which each frame of a video is treated as a single unit. And, as an open standard, JPEG2000 supports every resolution, colour depth, number of components and frame rates. To move to 4K and to solve
the small bandwidth issue that is preventing raw or uncompressed video, everybody can now also access to the new intoPIX light and small TICO compression technology. TICO compression has officially been launched at IBC and is based on market-driven research for low complexity compression. It aims to be utilised for a mezzanine 4K workflow from 2:1 to 4:1 compression with no effect on quality or latency. it is visually lossless with only a single pixel line delay. There is a strong desire to
Opinion
Gaël Rouvroy: ‘JPEG2000 supports every resolution’
produce content in 4K resolution on existing infrastructure. TICO solves the unwieldy files sizes that have scared off even big budget productions and transmission. This mezzanine compression can allow a 4K or 8K infrastructure at an equivalent price and complexity than existing baseband HD operations. I am glad to be here at
IBC2013. New challenges present themselves in the ever faster moving technology swirl. Our smart JPEG2000 solutions and the new TICO compression technology are great examples of how we are pushing as technology provider the boundaries and contributing towards the growth of the broadcast industry as a whole. 10.D31
