I'm writing a mdp file and I was looking for a way to specify (or modify) the HTTP header of all the request that the client do for a specific rapresentation. I would like to add an Authorization field inside of the http request. I was hoping to do so without edit the client's sw.
I have read the ISO/IEC 23009-1 but I have not found anything about it. Does someone know how to do that?
If you mean add the same base Url to all requests then this is possible and you can simply specify a base URL in the DASH manifest itself. It looks as simple as:
<BaseURL>http://example.com/ondemand/</BaseURL>
There is a complete example at the time of writing on the Mozilla pages including the line above here:
There is also a new DASH standard, still in definition phase so most likely hard to find implemtation at this point, designed to support a token based accesss authentication mechanism:
DASH-IF IMPLEMENTATION GUIDELINES: TOKEN-BASED ACCESS CONTROL FOR DASH (TAC) Scope
The scope of this document is to define a token-based access control mechanism and to enable the signaling of Authentication and Authorization (AA) protocols for DASH-based streaming. An Access Token is a proof that a DASH client or user of the client have been successfully authenticated and authorized in some pre-determined AA Systems to access a particular DASH resource, e.g. DASH segments or MPDs. This document defines an Access Token format for accessing DASH resources and its transport between a DASH client and a server, hence ensuring interoperability between content providers and content delivery networks. The document focuses on the signaling and exchange mechanisms to facilitate Access Token-protected requests for the delivery of MPDs, licenses, keys and segments. This document can be used in addition to the general DASH-IF Interoperability Points.
