  • Patent number: 11074287
    Abstract: Interface circuitry of an apparatus receives a first service data packet that includes at least first information for a first multimedia presentation frame and second information for a second multimedia presentation frame. Processing circuitry of the apparatus stores the first information and the second information in different rows having different row number in a service data table. Then the processing circuitry determines, from a preset database, first material data for the first multimedia presentation frame and second material data for the multimedia presentation frame based on material configuration information in the first service data packet. Further the processing circuitry associates the first material data and the second material data in a material data table with different row numbers in the service data table and generates first multimedia service data corresponding to the first service data packet based on the association between the service data table and the material data table.
