Compare Low delay and Random-access profile A comparison is made between Low delay and Random access configuration. HM 16.9 software is used. Table 1. Comparison of low delay profile for different QP. Video Sequence Configuration Quantization Parameter Average: YUV-PSNR in Db Average: BitRate in kbps Total Encoding Time in seconds Mobisode2_416x240_30.yuv Low_delay 24 45.9330 34.4280 66.230 sec 28 43.8753 21.1360 61.654 se 32 42.0079 14.2160 60.663 sec Low_delay 36 40.3097 10.0200 58.495 sec
