Method, apparatus, and non-transitory computer medium for obtaining a required frame size for a compressed data frame

An apparatus for obtaining a required frame size for a first compressed data frame to be generated by compressing at least a first data frame of a media file, the first compressed data frame for use by a user equipment in a communications network, the apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code;
• the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to perform:
• responsive to receiving a request for the media file from the user equipment, retrieve at least metadata of the media file;
• determining, based on the metadata, an average frame size of all the frames in the media file that are of a same frame type as the first frame, wherein the frame type of the first frame is one of an inter frame, a predicted frame, a bi-directionally predicted frame and an instantaneous decoder refresh frame;
• determine the required frame size for the compressed data frame based on a size of the at least the first data frame as indicated by the metadata, a compression parameter indicative of a requested compression factor for the at least the first data frame and a biasing factor that acts to reduce the value of the requested compression factor, wherein the biasing factor is determined dependent on the average frame size, and wherein the biasing factor acts to increase the required frame size of the first compressed data frame.
