Electronic systems with a wide variety of asynchronously interacting components come with high development costs. Since the number of links between components as well as the number of components itself are continuously rising, so is the system complexity, which leads to an increased probability of undetected errors. The search for these errors is expensive: Often, a manual observation of the running system is chosen, where only minor fractions of the system's behavior can be recorded for later use. Long-Time recordings would be, however, a valuable help especially for systems with elaborate renderings of system information like high-resolution car menus or navigation sequences. The data volume of the generated video sequences is high and must be compressed by embedded or mobile solutions only since the systems are tested live in the field and stationary lab equipment and PCs are not available.

The goal of this research is thus to develop efficient schemes for the compression of display data produced by these systems. The requirements to a potential compression core have significant differences to conventional compression standards. The steady stream of display data is composed of different data types, each one with special features and varying importance with regard to compression. A compression ratio which is adequate for one specific data type and offers sufficient data reconstruction after decompression might not qualify for another data type. Moreover, some data types come with characteristics that might yield significant reduction of compression bitrate if the compression core is designed for these input sequences properly.

Update Oct. 2013: The results of the research project "Compression of Displaydata" have successfully been integrated into the industry project EDAS. In cooperation with AUDI and in combination with the research project "Objective Quality Evaluation of Video", the chair LMS created the software EDAS (Error Detection and Archiving System). EDAS allows efficient real-time compression of display data with automated, event-based triggering of the compression chain. More information on EDAS can be found here. If you are interested in EDAS, its capabilities or related compression tasks, you can also directly contact Dominic Springer, Chair LMS.
