    摘要： A method, apparatus and non-transitory computer medium are provided 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 method comprises, responsive to receiving a request for the media file from the user equipment, retrieving at least metadata of the media file. The required frame size for the first compressed data frame is determined based on a size of the at least a first data frame as indicated by the metadata, a compression parameter indicative of a requested compression factor for the at least a first data frame and a biasing factor that acts to reduce the effect of the requested compression factor.

    摘要： A method, apparatus and non-transitory computer medium are provided for encoding data of a media file for playback by a user equipment in a communications network. A request for a range of encoded data is received from the user equipment, the encoded data to be generated by encoding data from an original media file. The request for a range of encoded data is converted into a request for a range of original data from the original media file. The range of original data is retrieved and the range of original data is encoded to generate encoded data. The requested range of encoded data, from the generated encoded data, is provided to the user equipment.

    摘要： There is described a method for determining a play duration estimate of an adaptive bit rate (ABR) media presentation. The method comprises receiving at a network entity a media playlist manifest file of the media presentation, wherein the manifest file is transmitted from a content server to a client and comprises a plurality of entries, each entry linking to a respective different one of a plurality of media segments of the media presentation. The method further comprises determining a data size of the manifest file; and determining a play duration estimate of the media presentation based on the determined data size of the manifest file, a first value that represents a data size of each of the plurality of entries in the manifest file and a second value that represents a play duration of each media segment of the plurality of media segments of the media presentation.
