摘要： A pre-FEC packet quality analyzer 310 measures quality information from a video stream which is not yet stored in a buffer 303 and on which a recovery process using FEC is not yet carried out. A post-FEC packet quality analyzer 308 measures quality information from the video stream which is stored in the buffer 303 and on which the recovery process using FEC is carried out. A video receiving terminal profile transmitter 307 generates a video receiving terminal profile including at least information showing the size of the buffer 303, and transmits the video receiving terminal profile to a home gateway device.

摘要： Disclosed is a video reproduction system including: a video receive terminal 6 for generating both first quality information for reproducing a degraded video which is played back by a user side from a video stream distributed thereto via an external network 3 and a home network 5, and quality control information based on the first quality information; a home gateway device 4 for generating second quality information for reproducing a virtual degraded video from which an influence of quality degradation caused by the home network 5 is removed on the basis of the quality control information; and a quality control system 8 for reproducing the degraded video which is played back by the user side by using both an original video stream which is yet to be distributed via the external network 3 and the first quality information while reproducing the virtual degraded video by using both the original video stream and the second quality information.
