Title:
MPEG2伝送ストリームにおける適応データ/コンテンツ挿入方法
Document Type and Number:
Japanese Patent JP2004532557
Kind Code:
A
Abstract:
An adaptive data insertion mechanism conducts future available bandwidth prediction/estimation by analyzing recent bandwidth in the transport stream which is consumed by general programs and inserts data by replacement of selected packets within the transport stream. Estimates of future available bandwidth are produced from periodic sampling of bandwidth utilization together with information regarding upcoming programming changes. The available bandwidth estimate is employed to prioritize and schedule data insertion within the transport stream. Scheduled data is inserted by replacement of selected packets within the received transport stream before forwarding.
