| JCTVC-B046 [T. Chujoh (Toshiba)] Summary of TE2 on IBDI and memory compression
This contribution was a summary of tool experiment 2: IBDI and memory compression. Nine companies and one university had been registered in TE2 and four proposed tools had been evaluated on the common conditions with cross-verification. There were two test conditions. One is the case of keeping the bit depth of reference memory to the input bit depth on IBDI and the other is the case of reduction of reference memory access bandwidth and size. Detailed results were to be reported by proponents.
It was reported that in the case of memory compression (i.e. use bit-depth increase only for processing, but store as 8-bit) the bit rate increase is typically effected as 0.5-1%. Investigations had mainly been done with KTA software
The question was asked whether we might expect very different results from different software basis environments (except perhaps complexity)? There seemed to be differing opinions on that topic.
