Content URL authentication for dash

摘要

Technology for content uniform resource locator (URL) authentication for dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH) is disclosed. In an example, a client device can include computer circuitry configured to: Receive a URL authentication key indicator and a content URL signature indicator from a server; generate a calculated URL signature for a URL in a DASH media presentation description (MPD) from the URL authentication key indicator; request the DASH segment when the calculated URL signature matches the received content URL signature, thereby authenticating content URL; and receive a DASH segment using the authenticated content URL. The received content URL signature is derived at the server from the content URL contained within the DASH segment URL.
