■■■ 使い方 ■■■

調査対象となる動画配信サービスは現在 Paravi、TVer、YouTube です。各サービスで動画を再生すると、体感品質値の計算に必要な動画のビットレート・解像度などの視聴情報を自動的に計測します。ある程度計測を続けると、動画プレイヤーのコントローラー表示時に、動画の左上に体感品質値が表示されます。

The video distribution services targeted by the survey are currently Paravi, TVer and YouTube. When you play a video on each service, it automatically measures viewing information such as the video bit rate and resolution required to calculate the quality of experience value. If measurement is continued to some extent, the quality of experience value will be displayed on the upper left of the video when the video player's controller is displayed.

After viewing, you can check the list of measurement results from the "Confirm Video Viewing Results" menu. You can compare the perceived quality at the time of each video playback with the average perceived quality value of all the measurements played in the same region or time zone.

If the target service does not support video playback on mobile websites, desktop websites will be displayed and measured.
