Abstract

The authors identify the main mechanism through which bits are consumed in the RBN (recursive binary nesting) coding scheme and determine ways in which this can be reduced. To this end, various forms of local motion-compensation are implemented and described, but the results are found to be disappointing. Different quantizers are then considered, but again the improvements were minimal. A scaled quantizer is introduced and shown to provide satisfactory performance. It is concluded that with the consequent increase in transmission efficiency for small block sample points, the use of RBN for quality coding of moving sequences at low channel rates is practicable.
