A computer-implemented method for tunneling content across a network in which the content has been configured into a digital format compatible with a player. Prior to starting a broadcast session, an announcement is transmitted across the network which contains control information concerning the broadcast session. The control information permits controlled reception of the configured content and includes a start-time. The configured content is encapsulated into a format that supports multicast distribution and controlled reception at particular machines. The configured content is multicast across the network in the encapsulated format to a multiplicity of machines in accordance with the start-time included in the announcement. The control information is used to selectively permit reception at particular ones of the multiplicity of machines, and the encapsulation is stripped from the multicast transmission at the particular machines. As a result, the multicast of the encapsulated data is compatible with the players on the particular machines. A system for implementing UDP tunneling multicasting method is also disclosed.

Methods for multicasting content

A system and method for broadcasting multicast transmissions of data content over a unidirectional network between a single server that executes a server process application and a plurality of clients, each of which executes a client process application. On the server side, the server includes a client emulator that executes a client emulator process application to convert unicast form data to multicast form data and on the client side each client operates in response to an emulator that executes a server emulator process application. Transmission of the data content takes place between the client emulator process on the server side and the server emulator process on the client side. Each client also includes and operates a client process application that receives data content from the server emulator process on the client side. On the client side, each client can have its own server emulator process or there can be a common server emulator process used by the client process application of all of the clients or groups of clients using a dedicated server emulator process for each group. The invention achieves multicast broadcast over a unicast network replacing the need for bi-directional networks and eliminates the need for a back channel and the need to send multiple copies of the data, thereby reducing the need for bandwidth and solving the problem of scalability of existing systems to broadcast multicast.
