The invention relates to a process for transmitting streaming digital content to a client device for access to digital content. The inventive process makes it possible, in particular, to apply an access control system to the protection of direct-mode video streams. The process also makes it possible to significantly improve the security and safety of the system, based on a periodic mandatory back-communication on the part of the client device. 1. A process for transmitting streaming digital content on an Internet data communication network , said Internet network being structured according to a multi-broadcasting routing mode , said process being implemented by a digital content transmission system comprising:{'b': 12', '13, 'claim-text': [{'b': 121', '122', '42', '111, 'at least one digital content encryption module (, ; ), connected to a streaming digital content source () via said Internet data communication network;'}, {'b': 124', '121', '122, 'a module () for storing cryptographic encryption keys and content identifiers, connected to the encryption module (, );'}], 'a digital rights management device (, ) including{'b': 14', '12', '13, 'claim-text': [{'b': '141', 'a module () for access, browsing and display of said streaming digital content;'}, {'b': 142', '141, 'a client module () for digital rights management, connected to the module () for access, browsing and display of said streaming digital content;'}], 'a client device () for accessing said streaming digital content, connected to the digital rights management device (, ) via said Internet data communication network, and including{'b': 121', '124', '141', '142', '42, 'each module (-, -, ) being formed by a software component, a hardware component, or a set of hardware and software components;'} [{'b': 121', '122', '42', '111', '31, 'the transmission to the encryption module (, ; ) of digital content, by the digital content source (), of streaming digital content (), via the Internet data communication ...
