Abstract
(EN)
Provided are a moving image distribution device and a moving image distribution system with which a moving image can be reproduced without defects or delay of the image, whereby a user can accurately control a machine of the device while watching a moving image captured by the device. This moving image distribution device has: an encoding unit that performs interframe encoding of moving images captured by an imaging unit, and generates an encoded moving image stream; and a reference frame generation management unit that receives, from a reception terminal for the encoded moving image stream, a reference frame generation stop signal or a reference frame generation restart signal. The encoding unit stops the generation of reference frames when the reference frame generation management unit receives the reference frame generation stop signal, and restarts generation of the reference frames when the reference frame generation management unit receives the reference frame generation restart signal, and performs the interframe encoding.

L'invention concerne un dispositif de distribution d'images animées et un système de distribution d'images animées avec lesquels une image animée peut être reproduite sans défaut ou retard de l'image, moyennant quoi un utilisateur peut commander avec précision une machine du dispositif tout en regardant une image animée capturée par le dispositif. Ce dispositif de distribution d'images animées comprend : une unité de codage qui effectue un codage intertrame d'images animées capturées par une unité d'imagerie, et qui génère un flux d'images animées codées; et une unité de gestion de génération de trames de référence qui reçoit, d'un terminal de réception pour le flux d'images animées codées, un signal d'arrêt de génération de trames de référence ou un signal de redémarrage de génération de trames de référence. L'unité de codage arrête la génération de trames de référence lorsque l'unité de gestion de génération de trames de référence reçoit le signal d'arrêt de génération de trames de référence, et redémarre la génération des trames de référence lorsque l'unité de gestion de génération de trames de référence reçoit le signal de redémarrage de génération de trames de référence, et effectue le codage intertrame.
