DATA SEND/RECEIVE METHOD AND DEVICE FOR MULTIMEDIA TRANSMITTING SYSTEM Russian patent published in 2017 - IPC H04N21/23 

FIELD: information technology.

SUBSTANCE: generating multimedia data packets based on a data block fragmented into one or more data sub-blocks, each of which includes a packet header and a payload, and transmitting the generated multimedia data packets. Wherein, each of the generated multimedia data packets contains type information indicating whether the relevant payload data included in the payload or the data block metadata or the data item extracted from the one or more data sub-blocks are contained. Wherein, the type information comprises a first value indicating that the corresponding payload data contains data block metadata if the corresponding payload data contains data block metadata, and type information also includes a second value indicating that the corresponding payload data contains a data element extracted from one or more data sub-blocks if the corresponding payload data contains a data item extracted from one or more data sub-blocks.
