Latest Patents

“Multicast Distribution of Incrementally Enhanced Content.” This patent describes encoding content into a low-resolution base stream and one or more higher-resolution incremental streams. A client device receives streams according to available bandwidth and its capabilities, joining multicast sessions as needed. It then combines and decodes the streams to display the content at an available resolution.

“Authorization, Authentication and Accounting Protocols in Multicast Content Distribution Networks.” This patent describes a process for securely adding an end-user computer to a multicast content distribution group. A network service intelligence platform authenticates a token and provides encrypted credentials identifying the user and requested content. After verifying those credentials in a join request, a network resource, such as an edge router, can add the user’s computer to the group.
