| description | To generate a second resolution video by dividing a first resolution video into videos, and enable transmission of both videos with low delay maintaining the high quality while eliminating the need for a dedicated device to generate the second resolution video from the first resolution video.SOLUTION: A transmission device 1 includes: a video division unit 11 that performs wavelet transform on an input video frame of a first resolution video so as to generate a first division frame consisting of low frequency components of the video frame and a second division frame consisting of high frequency components of the video frame; a video compression unit 12 that performs first compression processing on the first division frame to generate a first compression division frame, and also performs second compression processing on the second division frame to generate a second compression division frame; and a transmission unit 13 that transmits the first compression division frame and the second compression division frame via a transmission line 4. The first division frame is used as a video frame for a second resolution video a resolution of which is lower than the first resolution.SELECTED DRAWING: Figure 1
【課題】第１解像度の映像から第２解像度の映像を生成するための専用機器を不要としつつ、第１解像度の映像を映像分割することで第２解像度の映像を生成し、両映像を高画質を保ったまま低遅延に伝送可能とする。【解決手段】送信装置１は、入力される第１解像度の映像の映像フレームに対してウェーブレット変換を行うことにより、映像フレームの低周波数成分からなる第１分割フレーム及び映像フレームの高周波数成分からなる第２分割フレームを生成する映像分割部１１と、第１分割フレームに対して第１圧縮処理を行って第１圧縮分割フレームを生成するとともに、第２分割フレームに対して第２圧縮処理を行って第２圧縮分割フレームを生成する映像圧縮部１２と、伝送路４を介して、第１圧縮分割フレーム及び第２圧縮分割フレームを送信する送信部１３とを備え、第１分割フレームは、第１解像度よりも低い第２解像度の映像の映像フレームとして用いられる。【選択図】図１ |
