Koichi Masukura,Noboru Yamaguchi,Toshimitsu Kaneko,Tomoya Kodama,Takeshi Mita,Tadaaki Masuda,Wataru Asano +6 more
TL;DR: In this paper, a format conversion method comprising decoding the bit stream of a first encoded video data format, converting decoded video data to the second encoded data data format and encoding the converted video data in a process for converting the bit streams of the first encoded data format to the bitstream of the second encoder-decoder pair, and controlling processing parameters of at least one of the decoding, the converting and the encoding is presented.

Decoding apparatus and decoding method
Noboru Yamaguchi,Tomoya Kodama +1 more
TL;DR: In this article, a decoding apparatus has a de-ringing filter to filter image data decoded from encoded image data by orthogonal transformation encoding, where a subtracter generates an absolute value of difference between a value of a filter object pixel and a value selected from pixels surrounding the filter object pixels on the image data.
Patent
Video encoding apparatus and method and video encoding mode converting apparatus and method
TL;DR: In this paper, a video encoding apparatus comprises a motion vector detector to detect motion vectors of an input picture referring to a reference picture, and a predictive encoder to perform forward predictive encoding and bidirectional predictive encoding using the motion vector and the reference picture.

Motion picture storage apparatus and motion picture distributing system
Hisashi Aoki,Tatsuaki Iwata,Noboru Yamaguchi,Tadaaki Masuda,Tomoya Kodama,Koichi Masukura,Atsushi Matsumura +6 more
TL;DR: A motion picture storage apparatus includes a motion picture input unit which inputs motion picture data, a motion motion storage unit which sequentially stores the motion picture, a condition storage unit that stores a condition related to a desirable scene previously set by a user, and an information notifying unit which notifies the condition to a device of the user as discussed by the authors.

A highly parallelized H.265/HEVC real-time UHD software encoder
Tse kai Heng,Wataru Asano,Takayuki Itoh,Akiyuki Tanizawa,Jun Yamaguchi,Matsuo Takuya,Tomoya Kodama +6 more
TL;DR: This paper presents a highly parallelized HEVC software encoder suitable for broadcasting or network streaming applications and shows that the encoder system is about 15794 times faster than HEVC test model HM 11.0 and 13 times better than ×265, an open source HEVC encoder.
