USEFUL DATA FORMAT OF REAL-TIME TRANSPORT PROTOCOL Russian patent published in 2009 - IPC G06F15/00 

FIELD: information technologies.

SUBSTANCE: data flow is encoded for forming coding sections which are packed in RTP packets (packets created according to real-time transport protocol). Each RTP packet includes the title of RTP packet, one or several modules of useful data referring to common data flow, and the title of format of RTP useful data, which is provided for each useful data module and which contains boundary of useful data module for the appropriate encoding sections. Encoding sections are re-collected by using useful data modules from RTP packets and the appropriate boundary from the appropriate format title of RTP useful data. Re-collected encoding sections are decoded with the purpose of subsequent reproduction. Each format title of RTP useful data can have attributes which are used when reproducing useful data module. RTP packets can be sent from server to the user or from one peer-to-peer device to another peer-to-peer device.

EFFECT: enlarging functional capabilities owing to providing encoded data flow transfer mechanism at maintaining the block boundary of each encoded block.
