    • A bidirectional cable television ("CATV") system includes a CATV distributing device which transmits information through each of a plurality of channels. The information includes video information and added information relating to the content of the video information. A TV receiver then displays the video information that is transmitted from the CATV distributing device, and a processing terminal device compiles a picture that can be displayed on a monitor TV. The picture is compiled from the video information and added information that are sent from the CATV distributing device. The CATV distributing device includes a communication unit that transmits the video information and added information through each of the plurality of channel. The processing terminal device includes a communication unit that receives the video information and added information from the CATV distributing device, and a picture that is displayed on a monitor TV. The picture is displayed by dividing a single image field into a plurality of image regions and inserting the video information and added information which are made to correspond, mutually, in one of the image regions.
    • 双向有线电视(“CATV”)系统包括通过多个信道中的每一个发送信息的CATV分发设备。 信息包括与视频信息的内容相关的视频信息和附加信息。 然后,电视接收机显示从CATV分发装置发送的视频信息,处理终端装置编辑可以在监视器TV上显示的图像。 该图片是从CATV分发设备发送的视频信息和添加信息中编译的。 CATV分发装置包括通过多个信道中的每一个发送视频信息和添加信息的通信单元。 处理终端装置包括从CATV分配装置接收视频信息和添加的信息的通信单元以及显示在监视器TV上的图像。 通过将单个图像场划分成多个图像区域并且将在图像区域之一中彼此对应的视频信息和相加信息插入,来显示图像。
