Video coding techniques always needed to be enhanced. Digital images often results disrupt video display. The new video coding technique is introduced with the name of H.264/AVC.
It will ensure the protection of the most significant part of the information and will transmit data packets safely to in reaching the receiver.
For example if you are watching your favorite detective series. And at its climax, the very severe thunderstorm outside disturbs the digital image on your TV. The picture starts moving with still movements and it becomes difficult to detect the murderer. Why such things happen? The reason is its crystal-clear image quality. It causes its disruption. In the high definition TV or HDTV, it is having an increased volume of data.
In this situation the data packets are at exposed to a chance of damage during transmission. There is a chance of loss of information. This lays a big trouble for developers of video coding techniques. It becomes difficult for developers to recover the data if it is once lost. It requires extra effort to correct the error.
The researchers from three different German institutes are doing research work on improving standardized video coding techniques. These institutes are Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institute and HHI in Berlin. The research work is being done on techniques like the H.264/AVC format. The video technique is used by the YouTube video portal and Apple’s QuickTime player.
If an Internet connection becomes overloaded data packets are randomly discarded during transmission of information. The viewer sees a jerky picture as a result of that. The new extension of the H.264/AVC coding format saves the important parts of the data packets from being lost. This results in clear broadcasting without error. This was stated by Thomas Wiegand. He is the head of department at the HHI and a professor at the Berlin Institute of Technology.
