The data packets are exactly those needed to deliver the disruption-free video. The researchers use extra data packets in the transmission process to save the information if anything unexpectedly happens.
For example if two video packets are to be transmitted, an additional data packet is added equal to the sum of the bytes in the two video data packets. If any one of these transmitted data packets gets lost, the original information would be able to retrieve from the other two data packets. This was told by Wiegand.
This new coding format makes safe the most important part of the video. It makes it possible to restrict the extra data packets in keeping the major information. If it happened something undesirable, only the quality of the video will be affected. The extension of the H.264/AVC format is given the name of SVC. SVC stands for scalable video coding. It can work on all H.264/AVC-compatible devices. So you do not require purchasing new devices to use this video formatting.
Furthermore, it functions on its own, without any support of the overall data volume. It ensures error-free reception even in the case of high-resolution TV. The work on SVC standardization has reached to its completion. It will be used in different applications in near future. Some of these applications would be HDTV, the Internet, video conferences, surveillance technology or mobile radio.
This new extended format is displayed at the IBC conference held in Amsterdam. The conference continued from Sep-12 to Sep-16.
