Abstract
The transmission of sample or regular content such as audio data from a server to a single client over a communication network for test-listening or purchase is disclosed. A user may choose a musical selection for test-listening. The sample content may be a selected representative portion extracted from the regular content. If the user decides to purchase the sampled musical selection, the musical selection is transmitted from the server to the client computer. Additional information supplied along with the regular content identifies the musical selection and provides security. However, this additional information is not supplied when sample content is transmitted. Profile information may be supplied along with regular or sample content. The content may be classified, organized, and selected on a channel-by-channel basis. Regular content may be supplied to the client by downloading, while sample content may be supplied to the client by streaming.
