The usage of social media and sharing of multimedia content over the Internet are
rapidly increasing in recent time. Various facilities such as sharing of videos,
downloading and viewing them, and videoconferencing based on the Internet are
routine in the modern lifestyle. These all applications are consuming high channel
bandwidth and capacity, but most of the channels have limited bandwidth.
Therefore, the biggest problem for transmission of a high amount of video content
is that it cannot be transmitted over a small bandwidth channel. So, to overcome
this problem, compression of video is necessary before transmitting it.
The book presents compression techniques for digital video stream, describing their design using various image transforms, such as discrete cosine transform (DCT), discrete wavelet transform (DWT), and singular value decomposition (SVD). It first discusses the basic requirements and applications of video compression techniques. The book then addresses video compression using DCT as well as the hybrid compression technique, designed and implemented using DCT, DWT and SVD, demonstrating the simulation results for both. Lastly, it proposes future research directions in the field. |
