Abstract

The invention provides a method for obtaining a license, a method for playing a media content and a user terminal. The method for obtaining a license comprises the following steps that: a user terminal sends a service order request to a service platform through a browser and receives a service order result that is returned by the service platform, wherein the service order result carries a license extraction number and an address of a license server; according to the address, the user terminal sends a signed license obtaining request to a corresponded license server through a digital rights management (DRM) client, wherein the license obtaining request carries the license extraction number, a user public key and equipment information of the user terminal; and then the user terminal receives a license that is generated by the license server according to the license obtaining request. According to the invention, an applicability of a DRM client is improved.
