The existing products use EEP schemes instead of UEP schemes as well as different raptor codes and algorithms. The problems associated with these products lie in video distortion and inability to produce a clear video over certain connections. The advantage of UEP schemes give a more reliable and clear video feed over a broader range of connections.
Researchers at The University of Alabama have developed an invention to increase the quality of video transmitted over a wireless connection. The main difference is the cross-layer application UEP schemes. This means that images will be provided with different levels of protection based on prioritization of those images instead of applying the same protection to all images. In addition, the schemes eliminate the need for retransmission. These codes will allow companies to take more advantage or wireless video transmission.
• Higher video quality • Maximization of signal/noise ratio • Higher transmission reliability • More graceful distortion
