More Information
Summary:The invention discloses a method for inserting a voice data into a transmission data, which is used for a video editing device. The video editing device inserts a substitute digital voice data having a first interference position and a second interference position in a blanking zone of a line scanning digital data. With interference characters, the substitute digital voice data avoids being regarded as a starting mark area or an ending mark area when a digital television reads the substitute digital voice data from the line scanning digital data. Thus, the line scanning digital data can transmit digital image data and the substitute digital voice data at the same time to improve the transmission efficiency of the line scanning digital data.
