Title:
パケット化トランスポート・ストリームを処理する方法
Document Type and Number:
Japanese Patent JP4404271
Kind Code:
B2
Abstract:
The present invention is a system/method for layered entitlement data transmission/reception. A receiver embodiment includes a packet transport processor for selecting packets having payloads containing a conditional access payload header and a remaining payload of entitlement data. Respective payload headers include groups of bytes which are coded in a manner to allow or disallow the respective receiver from processing the entitlement data. A conditional access filter preprogrammed with a subscriber specific conditional access codeword examines respective byte groupings of the conditional access header for a match with the subscriber specific conditional access codeword. Only if a match occurs is the processor permitted to process the entitlement data.
