abstract

  • Rate control for video transmission becomes extremely important in "bandwidth-precious" scenarios and added real-time constraints_such as joint source channel coding make it even more vital. Hence, there has always been a demand for simple and efficient rate control algorithms. The approximate linear relationship between coding rate (R) and percentage of zeros among the quantized spatial transform coefficients (ρ) is exploited in the present work, to cater to such low-bandwidth, low-delay applications. The current rate control algorithm for H.264 is used as the benchmark for comparison. The extensive experimental results show that ρ -Domain model outperforms the existing algorithm with a more robust rate control, besides yielding a similar or improved Peak Signal to Noise Ratio (PSNR) and being faster.
