摘要
叙述了基于电视逆程数据插入技术的双通道图像／数据传输系统的设计及关键技术。该系统以电视信号为媒介，无需增加新的信道设备即可将模拟电视通道拓展为模拟／数字兼容通道，可提供传输速率达８６．４ｋｂ／ｓ的高速数据传输。系统性能可靠、传输速率快、纠错能力强，具有广阔的应用前景。
The design and key technology of bi-channel image/data transmission system which is basedOn the data transmission during video VBI (Vertical Blank Interval)are introduced in ths paper. the systemcxpands formal analog TV channel into a analog /digital compatible channel without adding any channelequipment.It can transmit data at a rate as highas86.4 kb/s The system with high transmission rate,powerful error correction capability works reliably. It can be widely used in many application fields.
