Abstract
Disclosed herein is an ad-hoc multimedia group communication terminal which is robust to packet loss and includes a multimedia transmitter. The media transmitter includes a reception status monitoring module, an error recovery level/traffic adjustment module, a bit stream division and error recovery data generation module, and a media data packet generation module. The reception status monitoring module recognizes packet reception status information relevant to the reception side terminals based on control packets from each of the reception side terminals. The error recovery level/traffic adjustment module adjusts the error recovery level and the amount of traffic of the media data packets. The bit stream division and error recovery data generation module generates error recovery data to be transmitted to the reception side terminals based on the error recovery level. The media data packet generation module generates the media data packets and error recovery data packets.
