IMEC ready to license SVC source code

Belgian research center IMEC is ready to license its source code for the upcoming scalable video coding (SVC) H.264 extension standard, which is due for release later this year.

IMEC says its optimized code shows a factor of two speed improvement compared to the standardization reference code.

Researchers at the center have also implemented a cross-layer design and runtime methodology that reduces power consumption and is capable of optimizing bandwidth usage during operation.

IMEC says the source code is now available for product development, and is targeted at system integrators of mobile devices and communication applications as well as fabless IC makers to help them extend their reference platforms with video functionality compatible with the SVC standard.

The research group is also calling on the industry to participate in its leading research on cross-layer management targeting low-power multimedia wireless communication.

IMEC says its researchers have performed many optimizations on the C++ reference model provided by the standardization body. It focused on the transformation of the code into a component-based structure, which led to the significant reduction in speed.

The group has also been working on a C++ to C conversion tool. This allows the conversion of the huge C++ code base to the C language, which is needed for many embedded platforms that use processors for which only C-compilers are available.

IMEC has also developed a cross-layer methodology that allows the continuous optimization of power consumption and bandwidth in wireless networks while guaranteeing QoS levels.

Special controllers have been added at the base station and on user devices. This cross-layer methodology is essential to exploit the advantages offered by SVC, say the researchers.
