HIGH-DEFINITION DIGITAL VIDEO SIGNAL TRANSMISSION METHOD AND DEVICE, CAMERA AND ACQUISITION DEVICE |
摘要 |
Disclosed are a high-definition digital video signal transmission method and device, a high-definition digital video camera and a video acquisition device. The technical solution provided in the embodiments of the present invention comprises: transcoding a high-definition digital video signal in accordance with a line-by-line sequence at a sending end to obtain an analogue video line signal, and sending analogue video line data which is obtained by conversion; and receiving the analogue video line data at a receiving end, and conducting decoding conversion on the received analogue video line data to obtain high-definition digital video line data. The present invention can convert a high-definition digital video signal into an analogue video signal to conduct transmission, thereby being able to solve the problem that a high-definition digital video signal cannot be transmitted for a long distance in the existing high-definition digital video monitoring technology. |
