Title:
A METHOD FOR SUPPORTING MULTIMEDIA DATA TRANSMISSION WITH ERROR RESILIENCE
Document Type and Number:
WIPO Patent Application WO/2007/045141
Kind Code:
A1
Abstract:
A method for supporting multimedia data transmission with error resilience is
disclosed, thereby the error resilience mechanism of multimedia data real-time transmission
can be realized on the transmission protocol layer. In present invention, at
first, it provides multimedia data real-time transmission by providing the
ERRTP protocol which carrying information about the forward error correction(FEC)
coding manner to the exist RTP protocol, so that it can mark the information about
the corresponding FEC coding manner for multimedia data at the same time it is
transmitted on ERRTP, thereby the error resilience mechanism can be introduced
in transmission layer. Next, each standby FEC coding manner can be selected according
to present network condition and the level of importance about the multimedia
data at transmitting end, so that it can achieve the purpose of protect based on
the level, and can realize the equilibrium about the protect ability and the transmission
efficiency.
