| Abstract(in English) | In video streaming on the Internet, getting a good encoding recipe (i.e. bitrate-resolution pairs) is a main problem to deliver the highest quality video streams. By using multiple bitrate/resolution encoding like MPEG-DASH, video streaming services can deliver the best video stream to a client, under the conditions of the client’s available bandwidth and viewing device capability. However, conventional fixed encoding recipes (i.e. resolution-bitrate pairs) suffer from many problems, such as improper resolution selection and stream redundancy. To avoid these problems, we propose a novel video coding method, which generates multiple representations with constant Just-Noticeable Difference (JND) interval, using a JND scale estimator which we developed with Support Vector Regression (SVR). Experimental results confirm that our proposed method can achieve better rate-JND characteristics than conventional fixed recipe. |
