Abstract
Modern digital TV-systems encompass digital demodulation and required
audiovisual signal processing incorporating an uni ed-memory architecture.
The bottleneck of such a System-on-Chip (SoC) is the connection to the external
memory. As the video signal consumes the majority of the involved
bandwidth, embedded video compression allows bandwidth reduction, enabling
cost e ective systems. The embedded video compression must be visual
lossless and cost e ective. This requires a high e cient de-correlation step to
limit the amount of quantization, thus avoiding a decrease of picture quality.
In this thesis, video characterization has been conducted, resulting in
novel video de-correlation concepts. Based on these concepts, a DCT-based
codec exploiting symmetrical features, structure repetitions and prediction
techniques in the DCT transform domain has been developed. From the results
it can be concluded, that symmetrical features turn out to be an e cient
method to compress video, preserving the demanded high picture quality at
acceptable computational cost.
