APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING MULTIMEDIA DATA IN MOBILE COMMUNICATION SYSTEM

摘要

The present disclosure dynamically selects an optimal parameter so as to stably stream an image without user's setting in a network environment. The present disclosure determines (schedules) a path to which a general packet is to be distributed based on a path cost indicator, and determines a symbol size and the number of source symbols, which minimize or sufficiently reduce a cost function.

主权项

1. A method of transmitting multimedia data in a mobile communication system, the method comprising:
setting a size of a source symbol and a number of source symbols to initial values; determining a packet distribution vector by a path cost indicator (PCI); determining a code rate based on the packet distribution vector; calculating a penalty function based on the code rate; determining, for each block, the size of a source symbol and the number of source symbols, which have the lowest penalty function value; and transmitting encoded multimedia data based on the size of the source symbol and the number of source symbols.
