Abstract

In most existing video codecs, motion compensation is carried out by referencing the prior decoded frame. So far, multiple reference frames have been considered only to a very limited extent for two reasons. First, they simply could not be afforded. However, the continuously dropping costs of semiconductors are making the storage and processing of multiple reference frames possible. Second, it was not believed that multiple reference frames would significantly improve coding efficiency. In this chapter, methods for multi-frame MCP are investigated and it is shown that significant improvements in coding efficiency are, in fact, possible.
