Abstract
The present invention relates to a method of scalable transmission of video objects segmented by content-base, comprising the steps of: constituting a set of video objects to be transferred (TxSet); checking as to whether TxSet is the last portion of a video sequence, and then calculating a current transmission rate and a transmission tolerance data size; constituting a video object evaluation group (egs); comparing the data size of the video object evaluation group with a data size of TxSet elements plus a data amount of the video objects of the transmission priority j and then adding the video objection evaluation group (egs) to the TxSet; and checking as to whether the video object of the transmission priority j is the last element of the video object evaluation group i.
