Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a video distribution apparatus and a video distribution system that enable a user to control machine of a device accurately while watching a captured video of the device by enabling reproduction of the video without causing loss or delay of images.

SOLUTION: A video distribution apparatus according to the present invention includes an encoding unit that performs interframe encoding on a video captured by an imaging unit and generates an encoded video stream and a reference frame generation managing unit that receives a reference frame generation stop signal or a reference frame generation resumption signal from a receiving terminal of the encoded video stream, and the encoding unit stops generation of a reference frame when the reference frame generation managing unit receives the reference frame generation stop signal, and resumes the generation of the reference frame when the reference frame generation managing unit receives the reference frame generation resumption signal to perform interframe encoding.

【課題】画像の欠損や遅延を生じさせることなく動画を再生できるようにすることで、ユーザが装置を撮像した動画を見ながら正確にその装置の機械を制御することを可能とする動画配信装置及び動画配信システムを提供する。
【解決手段】本発明の動画配信装置は、撮像部で撮像した動画をフレーム間符号化し、符号化した動画ストリームを生成する符号化部と、符号化した動画ストリームの受信端末から、基準フレーム生成停止信号または基準フレーム生成再開信号を受信する基準フレーム生成管理部と、を有し、符号化部は、基準フレーム生成管理部が基準フレーム生成停止信号を受信すると、基準フレームの生成を停止し、基準フレーム生成再開信号を受信すると、基準フレームの生成を再開して、フレーム間符号化を行う。
