Abstract

Video consumption over VANETs will increase significantly bandwidth and will occupy an important part of the overall data traffic. To decrease the load on the VANET infrastructure and reduce bandwidth taken by video, high efficiency video codecs have been developed. In this work, a benchmarking of H.265/HEVC, H.264/AVC and Google VP9 has been conducted by means of objective and subjective evaluations, assuming an urban VANET scenario. Considering a wide range of bit rates from very low to high, results show a clear advantage of HEVC with average bit rate savings of 27% when compared to VP9 and 49% when compared to AVC.

Notes

  1. 1.

    The Quantization Parameter (QP) regulates how much spatial detail is saved. When QP is very small, almost all that detail is retained. As QP is increased, some of that detail is aggregated so that the bit rate drops, but at the price of some increase in distortion and some loss of quality.

  2. 2.

    Bj\(\phi \)ntegaard Delta-Rate (BD-Rate) is the average bit rate difference in percentage for the same PSNR.
