CONTENT URL AUTHENTICATION FOR DASH
First Claim
1. A client device operable for content uniform resource locator (URL) authentication for dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH), having 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, wherein the received content URL signature is derived at the server from the content URL contained within the DASH segment URL; and
receive a DASH segment using the authenticated content URL.

Abstract
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.
