Abstract
Several embodiments of the present invention are described for a media data processing method, apparatus and system. An example method comprises: obtaining an optical signal of a sampling point by a collection device at the source end in an acquisition of media data; according to an opto-electronic transfer control parameter, performing opto-electronic transfer for the optical signal of the sampling point to obtain a transferred electrical signal, wherein the opto-electronic transfer control parameter is determined on the basis of an optical signal intensity of the optical signal of the sampling point; and encoding the electrical signal and opto-electronic transfer control parameter to obtain a bitstream. According to the embodiment of the present invention, the problem of the lower accuracy in the media data processing is solved, thereby obtaining the effect of improving the accuracy in the media data processing.
