Claim 5:
6. The method of claim 1, further comprising:
determining, by the edge server, a weight of each data frame of the on-demand video in an entire video in advance according to a principle that the more important the data frame is, the greater the weight is, by using a machine learning method;
after receiving a stunt playing on-demand request for the on-demand video from the user equipment, determining, by the edge server, a weight threshold corresponding to a compression strength specified in the stunt playing on-demand request according to a preset mapping relationship between compression strengths and weight thresholds; for a data packet to be transmitted to the user equipment, which is currently stored in a cache;
discarding, by the edge server, a data frame contained in the data packet, whose weight is less than the determined weight threshold;
performing encoding and multiplexing operations on a data frame contained in the data packet, whose weight is greater than or equal to the determined weight threshold; and
transmitting a generated data packet to the user equipment.
