Quadrature carrier multiplexing based digital video compression

This paper presents a new video compression algorithm with improved compression performance. The proposed algorithm works with any existing compression algorithm to provide added compression. This kind of series application of algorithm with existing algorithms provides flexibility it terms of implementation and integration with existing products. The concept proposed in this paper uses the concept of quadrature carrier multiplexing in the digital domain to compress alternate frames on quadrature digital virtual carriers to reduce the size of the video. Since the algorithm is generic it can be applied to any packets or chunks of data. Experiments were performed to quantitatively evaluate the performance of the proposed compression algorithm. The results of the experiments showed that using the proposed algorithm with existing MPEG-4 compression yields 50% compression over MPEG-4 standard without any perceivable change in the video quality especially at higher resolutions.
