The invention relates to a
big data aided
video transmission method based on digital-analog
hybrid. The method comprises the following steps: step 1), based on a
wireless video transmission system with a maximum
signal to
noise ratio, specifically as follows: establishing a pseudo analog
video transmission framework, based on Bayesian reasoning, obtaining a minimum mean-
square error estimation of a receiving end reconstruction video
signal, and acquiring best prior knowledge; step 2), transmitting a
signal by a signal transmitting end of the
big data aided video transmission method based on digital-analog
hybrid; and step 3), reconstructing a video by a signal receiving end of the
big data aided video transmission method based on digital-analog
hybrid. Assuming that the transmitting end and the receiving end have the same
cloud data, information which is most relevant to a transmission signal in the big data is extracted to be used for reconstructing an aided video, the best prior knowledge is extracted by maximizing the
signal to noise ratio of the receiving end, and a corresponding standard is set at the transmitting end to determine whether to transmit an original video signal, so as to save a
transmission bandwidth. Compared with the prior art, the invention fully uses information relevant to the transmission signal in cloud
mass data, so that the visual quality of the transmitted video can be enhanced.
