Classification: CPC H | IPC H

Claim 12:
13. The transmission control apparatus of claim 8, wherein the processor is further configured to:
determine 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; and after receiving a stunt playing on-demand request for the on-demand video from the user equipment,
determine 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, discard a data frame contained in the data packet, whose weight is less than the determined weight threshold,
perform 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
transmit a generated data packet to the user equipment.
