Each video was subsequently encoded using three encoding profiles (HLS reference [4], CAE, and CAE with enabled "true resolution" detection (CAE+TR). Then we instrumented players to play the content and collected the playback statistics. savings. For example, we notice 26.97% savings in bandwidth and 28.41% in storage for basketball content. These are significant savings realized by using a sample of real-world media content.
