SECURELY INGESTING ENCRYPTED CONTENT INTO CONTENT SERVERS |
摘要 |
A system and method are directed towards including buffer packets into an unencrypted content stream at a same location as encryption related information such as an ECM, an EMM message, or the like, would be in a corresponding encrypted content stream. The buffer packets may comprise virtually any information, including a null packet, an ECM message. By inserting buffer packets in the same location, an overall file size, and frame locationing may be made to match the file size, and frame locationing of the encrypted content stream. The modified unencrypted content stream may be employed to generate trick play files, such as a fast forward file, fast reverse file, and so forth, as well as a corresponding index file that indicates locations of relevant content frames in the unencrypted content stream and the trick play files.
