| Zusammenfassung: | To continue high-quality video distribution appropriately even when a network bandwidth fluctuates during the video distribution.SOLUTION: A video distribution device includes distribution means for distributing a video to a client device via a network, measurement means for measuring available bandwidth, which indicates the degree of margin of network bandwidth to and from the client device, and control means for controlling the amount of video data to be delivered to the client device by the distribution means on the basis of the available bandwidth measured by the measurement means and an acceptable image quality range of the video.SELECTED DRAWING: Figure 3
【課題】映像配信中にネットワーク帯域が変動した場合であっても、適切に高品質な映像配信を継続する。【解決手段】映像配信装置は、ネットワークを介してクライアント装置に対して映像を配信する配信手段と、クライアント装置との間のネットワーク帯域の余裕の程度を示す使用可能帯域を測定する測定手段と、測定手段により測定された使用可能帯域と、映像の許容する画質範囲とに基づいて、配信手段によりクライアント装置へ配信する映像のデータ量を制御する制御手段と、を備える。【選択図】 図３ |
