Abstract
The amount of transmitted video content is rising sharply in modern telecommunication systems. This is especially true for streaming video. In this regard, the requirements are increased not only in terms of the compression ratio and the quality of the transmitted image, but also in terms of video codec performance.
The usage of multichannel wavelet transform may be a way to increase the compression ratio while maintaining the same quality of reconstructed images.
Therefore, the aim of the study is to implement multichannel wavelet decomposition based video codec and to make use of it in real-time mode.
Multichannel wavelet video codec based on new filter banks specially designed for wavelet decomposition of images into a certain number of channels has been implemented within the research.
Video compression results for various number of decomposition channels are presented in the efficiency evaluation of multichannel wavelet video codec.
