| Summary: | Ultrahigh definition video streaming has been explored in recent years. Most recently the possibility of 4kUHD video streaming over wireless 802.11n was presented, using preencoded video. Live encoding for streaming using x264 has proven to be very slow. The use of parallel encoding has been explored to speed up the process using CUDA. However there hasnot been a parallel implementation for video streaming. We therefore present for the first time a novel implementation of 4kUHD live encoding for streaming over a wireless network at low bitrate indoors, using CUDA for parallel H264 encoding. Our experimental results are used to verify our claim. |
