    • A video delivery system and method which can reduce the amount of data stream to be transmitted without damaging a reproduced image when a screen is partially concealed in paid digital broadcasting. A video signal transmitter comprises a shield processing part for concealing an input video signal such that a part of each frame screen included in the input video signal presents a predetermined pattern, a first compression encoding part for applying compression encoding to the concealed video signal at a high compression ratio, a subtracting part for extracting a differential signal between the compression encoded video signal and the input video signal, a second compression encoding part for applying compression encoding to the differential signal at a low compression ratio, and an encrypting part for applying predetermined encryption to an output signal from the second compression encoding part, wherein the encrypted signal is multiplexed on an output signal from the first compression encoding part, and the multiplexed signal is transmitted.
    • 一种视频传送系统和方法,当屏幕被部分隐藏在付费数字广播中时,可以减少要发送的数据流的数量而不损害再现的图像。 视频信号发送器包括:屏蔽处理部分,用于隐藏输入视频信号,使得包含在输入视频信号中的每个帧屏幕的一部分呈现预定模式;第一压缩编码部分,用于在隐藏的视频信号中以 高压缩率,用于提取压缩编码视频信号和输入视频信号之间的差分信号的减法部分,用于以低压缩比向差分信号应用压缩编码的第二压缩编码部分,以及用于施加预定 加密到来自第二压缩编码部分的输出信号,其中加密信号被多路复用在来自第一压缩编码部分的输出信号上,并且发送多路复用信号。
