document: MPEG-4 video object-based rate allocation with variable temporal rates In object-based coding , bit allocation is performed at the object level and temporal rates of different objects may vary . The proposed algorithm deals with these two issues when coding multiple video objects -LRB- MVOs -RRB- . The proposed algorithm is able to successfully achieve the target bit rate , effectively code arbitrarily shaped MVOs with different temporal rates , and maintain a stable buffer level
