Lightweight codec points apps at IP

For applications requiring a lightweight image coding system for inside cameras, video over IP and KVM extension, Fraunhofer IIS has developed a clever codec offering compression ratios of 1.2 to 1.6. Its single project partner was IHSE for the KVM extender developer.

“We saw that the implementation of JPEG 2000 was rather complex, and thought to develop an application for minimal compression ratios, with low hardware complexity and low latency,” said Wolfgang Heppner, head of systems and devices group Fraunhofer IIS.

“It is actually a niche market. You have to think that the field of image compression has JPEG 2000 and H.264 and that they are special applications that have other requirements,” he added.

The booth demo had the KVM application live. “You have a box you connect to the PC and the output of the graphic card and on the other side you have your video stream, and there you are dependent on very low latency because you want to move the mouse and see it immediately,” said Heppner.

“We are seeing a change in the workflow, as everyone is moving to IP. There you have the 10 Gigabit bandwidth ceiling, so for apps that just want to go with a light codec under this limit, this is a perfect solution,” he added. “You do not have to do it with ASICS or with big computational power, and you get your content with about 1.4 compression under the bandwidth limit.”

Users could transfer LICI compressed camera rushes from a venue to the studio and then do the post-processing and transcoding. The codec then does the transcoding for delivery.

“Normally we do that transcode in live workflow,” said Heppner. “It is a fully transparent technology that enables you to move to IP.”
