    • The present invention relates to a video transmission and receiving method and apparatus using a radio communication instrument which are capable of transferring and receiving various information such as a video signal using a conventional radio communication instrument without providing an additional apparatus. The radio transmission and receiving apparatus using a radio communication instrument includes an input unit for receiving a video signal, a capture and analog/digital converter for capturing the inputted video signal by a field or frame and converting into a digital signal, a storing unit for temporarily storing the converted digital video data, a central processing unit, an encryption code generator including a variation table by which the central processing unit changes a transmission sequence of the JPEG-compressed data in a transmission mode and the sequence of the data of the signal having a changed sequence is recovered in a receiving mode, and a display unit for displaying a video signal which is currently inputted or received.
    • 本发明涉及使用无线通信装置的视频发送和接收方法和装置,其能够使用传统的无线电通信装置传送和接收诸如视频信号的各种信息,而不需要提供附加的装置。 使用无线电通信装置的无线电发送和接收装置包括用于接收视频信号的输入单元,用于通过场或帧捕获输入的视频信号并将其转换为数字信号的捕获和模拟/数字转换器,用于 临时存储转换的数字视频数据,中央处理单元,加密码发生器,包括变化表,中央处理单元通过该变化表改变发送模式下的JPEG压缩数据的发送顺序和信号的数据序列 在接收模式下恢复具有改变的序列的显示单元,以及用于显示当前输入或接收的视频信号的显示单元。
