On Error and Bitrate Tradeoff in Visible Light Communication System to ensure HEVC Video Quality

Recently, Visible Light Communication (VLC) has got increasing attention in the field of indoor wireless communications. Color Shift Keying (CSK) is a VLC modulation scheme proposed by IEEE 802.15.7 task group. In this method diffused light wavelengths are symbol points so that their combination provides an overall white sensation. Modulation depth in CSK influences Bit Error Rate (BER) as determines transmission rate. In the case of video streaming over VLC network, video encoding rate should be compatible with the transmission rate, consequently, affects video quality. We have proposed an adaptive modulation scheme for video transmission over VLC network considering the dependency of encoded video quality and modulation BER to modulation. This algorithm jointly minimizes BER and encoded video distortion via adaptive selection of CSK modulation depth to decline frame loss besides desirable video quality protection.
