具有用于显示可变尺寸辅助图像的设备的电视系统
摘要：
具有用于显示可变尺寸辅助图像的设备的电视系统。显示对应主视频信号的主图像和对应辅助视频信号的辅助图像的设备和方法，包括：提供对应主图像的主视频信号的装置；提供辅助视频信号的装置；按照给定的压缩率压缩辅助视频信号的装置，产生与具有第一尺寸的辅助图像相对应的压缩的辅助视频信号；组合主视频信号和压缩辅助视频信号的装置，从而产生与组合了主视频图像和辅助图像的画面相对应的组合PIP视频信号；将组合视频信号连接到显示器的装置；响应用户发出的指令信号的装置，有选择地将辅助图像剪切固定的量以有选择地将辅助图像的尺寸改变固定的量，从供收看的第一尺寸改变成供收看的较小的第二固定尺寸但不改变压缩辅助视频信号的压缩率和宽高比。
摘要（英）：

A television system with provisions for displaying an auxiliary image of variable size is provided. An apparatus and process for displaying a main image corresponding to a main video signal and an auxiliary image corresponding to an auxiliary video signal, includes: a provision for providing a main video signal corresponding to the main image; a provision for providing an auxiliary video signal; a provision for compressing the auxiliary video signal according to the given compression rate and generating a compressed auxiliary video signal corresponding to the auxiliary image with a first area; a provision for combining the main video signal and the compressed auxiliary video signal, accordingly generating a combined PIP video signal corresponding to the picture combining the main video image and the auxiliary image; a provision for connecting the combined video signal to a display; and a provisions for displaying an auxiliary image of variable size, selectively cropping a fixed amountof the auxiliary image, in response to a command signal which a user inputs, in order to selectively change area of the auxiliary image as a fixed size from a first area to a smaller fixed second area without changing the compression ratio and aspect ratio of the compressed auxiliary video signal.
