Dynamic Adaptive Streaming Over Hypertext Transfer Protocol Service Protection

摘要

A method comprising encrypting a segment in response to receiving a segment request to generate an encrypted segment, and sending the encrypted segment, wherein encrypting the segment comprises encrypting a data content segment and a non-media segment in accordance with information provided in a dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH) media presentation description (MPD), and wherein encrypting the segment generates an encrypted data content segment and an encrypted non-media segment. A method comprising sending a segment request, receiving an encrypted segment, wherein the encrypted segment comprises an encrypted data content segment and an encrypted non-media segment, and decrypting the encrypted segment in accordance with information provided in a DASH MPD to generate a data content segment and a non-media segment, wherein the non-media segment comprises a non-playable media.
