Abstract
In this paper,a video compression and transmission method based on sparse coding is studied to solve the problem of digital television signal compression and transmission.Focusing on sparse video coding based on wavelet transform,dictionary learning is introduced to optimize sparse coding.The experimental results show that the proposed method can effectively maintain video quality while maintaining high compression rate,which provides a new idea and method for efficient compression and transmission of digital television signals.
