On the cost of backward compatibility for communication codecs

Konstantin Schmidt, Markus Schnell, Nikolaus Rettelbach, Manfred Lutzky, Jochen Issing

Super wideband (SWB) communication calls more and more attention as can be seen by the standardization activities of SWB extensions for well-established wideband codecs, e.g. G.722 or G.711.1. This paper presents a technical solution for extending the G.722 codec and compares the new technology to other standardized SWB codecs. Hereby, a closer look is given on the concept of extending technologies to more capabilities in contrast to non-backwards compatible solutions.
