Abstract
A Multiple Bit Rate (MBR) video coding method and apparatus for performing video encodings at multiple bit rates and for performing advantageous switching therebetween. Frequent switching points and high video coding efficiency are achieved with use of a plurality of video encodings at each of a plurality of bit rates, wherein the switching points between multiple encodings at a given bit rate are shifted with respect to one another so that the frequency of available switching points is significantly improved without a corresponding loss of coding quality. In addition, one or more 'high quality' encodings may be provided at each bit rate, wherein the 'high quality' encodings employ infrequent switching points, providing a very high quality encoding at the given bit rate which may be used (or switched to) whenever possible.
