Abstract:
(EN) In the present invention, a throughput measurement unit (104) measures the throughput of communication with a reception terminal (2), a segment pattern generation unit (105) generates multiple patterns, each comprising multiple time segments obtained by segmenting a predetermined length of time, a QoE calculation unit (106) calculates a quality-of-experience for a video from a predicted future throughput value for each of the patterns generated by the segment pattern generation unit (105), and a parameter determination unit (107) determines an encoding parameter for each of the time segments of a single pattern wherein the quality-of-experience for a video is the highest.
(FR) Dans la présente invention, une unité de mesure de débit (104) mesure le débit de communication avec un terminal de réception (2), une unité de génération de motifs de segment (105) génère de multiples motifs, comprenant chacun de multiples segments temporels obtenus par segmentation d'une durée prédéterminée, une unité de calcul de QoE (106) calcule une qualité d'expérience pour une vidéo à partir d'une valeur de débit future prédite pour chacun des motifs générés par l'unité de génération de motifs de segment (105), et une unité de détermination de paramètre (107) détermine un paramètre de codage pour chacun des segments temporels d'un motif unique, la qualité d'expérience pour une vidéo étant la plus élevée.
(JA) スループット計測部（１０４）は、受信端末（２）との間の通信のスループットを計測し、分割パターン生成部（１０５）は、所定時間を分割することによって、複数の分割時間でそれぞれ構成される複数のパターンを生成し、ＱｏＥ算出部（１０６）は、分割パターン生成部（１０５）が生成したパターンごとに、未来のスループットの予測値から、映像の体感品質を算出し、パラメータ決定部（１０７）は、映像の体感品質が最大になる１つのパターンの分割時間ごとに、符号化パラメータを決定する。
