Abstract
A server/client for a network-based multicast system has a media services manager and one or more media service providers. When functioning as a server, the media service providers receive data corresponding to a channel having one or more related data streams, where each media service provider receives data corresponding to a data stream of the channel. In the server, the media services manager receives the data from the media service providers and transmits the data to the network. When functioning as a client, the media services manager receives data from the network for a selected channel having one or more related data streams. In the client, the media service providers receive and play the data from the media services manager, where each media service provider receives and plays data corresponding to a data stream of the channel. In a preferred embodiment, a channel has logically related audio, video, and/or text data streams.
