Patent number: 9894391Abstract: A distribution management apparatus includes a generator configured to generate still-picture data from content data, a converter configured to convert the still-picture data into video data, and a distributer configured to distribute the video data to each of a first communication terminal and a second communication terminal, which are capable of playing back and displaying the video data. When first operation data indicating an operation of zooming into a partial region of the video data being played back and displayed on the first communication terminal is transmitted, the converter generates video data representing a partial region, which depends on display/playback capabilities of the second communication terminal, of the video data being played back and displayed on the first communication terminal, and the distributer distributes the video data representing the partial region generated by the converter to the second communication terminal.Type: GrantFiled: September 4, 2014Date of Patent: February 13, 2018Assignee: RICOH COMPANY, LIMITEDInventors: Masaki Ninomiya, Kiyoshi Kasatani, Yasuhiro Kuba, Masahiro Kuwata, Haruo Shida, Kenji Namie, Atsushi Okada, Katsuyuki Omura
