Video sequence image broadcasting method for e.g. Internet protocol network, involves determining urgency level for each of error messages based on analysis of messages, and making decision for sending response message based on level

摘要

#CMT# #/CMT# The method involves incorporating images of a video sequence into an output stream for transmitting the images to terminals e.g. personal computer. Error messages relative to restitution of the images are received from the terminals via a return channel. The error messages are analyzed to identify non/badly restituted images, and response messages including correction images are determined. Urgency level for each error message is determined based on the analysis, and a decision for sending a response message to the error message is made based on the urgency level. #CMT# : #/CMT# An independent claim is also included for a computer program comprising software instructions for implementing a video sequence image broadcasting method. #CMT#USE : #/CMT# Used in a multipoint control unit of a video sequence broadcasting system (claimed) for broadcasting an image of a video sequence to a terminal e.g. personal computer, via a telecommunication network such as Internet protocol (IP) network. #CMT#ADVANTAGE : #/CMT# The decision for sending the response message to the error message is made based on the urgency level, thus optimizing the response messages in order to improve the utilization of the return channel. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flowchart of a video sequence image broadcasting method.`(Drawing includes non-English language text)`.
