Scalable Video Coding (SVC) is an extension, which is also known as Annex G, to the H.264/MPEG-4 AVC video encoding standard. The objective of SVC is to enable the encoding of a video bitstream that contains one or more subset bitstreams. These subset bitstreams consist of one of more layers, each of which contain data that, when added to data from other layers, increases the decoded video frame rate, resolution, fidelity, or a combination of these three.
“Upgrading an existing analog video surveillance or security system to network functionality is now both easier and more economical with AFI’s network communication devices,” said Jack Fernandes, President and CEO of AFI. “The white paper offers a practical overview, with examples, of how our Net I/O series allows network connectivity of virtually any video, access control and alarm or fire/safety devices.” 
Transmission is rapidly becoming the key component of video security network systems. As IP cameras, digital and network recorders improve in quality along with the advent of cloud storage the criteria for system performance will depend on how signals are transmitted between various points on the network with the least amount of information loss while maintaining the best possible quality.
