发明名称 Common scrambling
摘要 A transport stream is encrypted in such a manner that the stream may be processed without requiring encrypted portions of the stream to be decrypted. Thus, an analysis is performed on the stream to determine at least one portion of the stream that is to pass unencrypted, thus enabling the stream to be processed in a manner that bypasses encrypted portions of the stream.
