画面転送システムでは，送信元の処理負荷やネットワークの遅延などの様々な要因で周期的な画面変化を再現しにくいという問題がある．そこで我々は，送受信端末間の画面転送を中継するサーバを配置し，このサーバ内で周期変化の検出と受信端末に送信するタイミングの調整を行う，周期変化補正機能を提案してきた．本稿では，様々なネットワーク環境や画面変化を想定した実験に基づき，周期変化補正機能の適用範囲を明らかにする．%In a remote desktop system where the screen image of a terminal is transferred over the network to another terminal, it is difficult to accurately reproduce periodic screen update patterns such as blinking alert messages. In previous work, we proposed a timing correction method where a relay server acting between the sending and the receiving terminals detects periodic screen update patterns and regulates the timing of updates sent to the receiving terminal. In this paper, we explore the applicable scope of the proposed method by doing some experiments in varied network environments and with different screen update patterns.
