Abstract
An arrangement that is particularly suitable for Internet, where a user receives a number of channels concurrently. The channel that is of current interest to the user is sent with a given bandwidth, while other channels (surfing channels) are sent at reduced bandwidth. The user's receiver buffers all of the received channels, and plays the channel of current interest in full fidelity. When a user wishes to surf, the buffered surfing channels are made available and are played to the user in accordance with the user's requests. When the user selects another channel to be of current interest, the user's terminal sends out a request for the new channel to be sent to the user at the given bandwidth, and thence provides the user with the newly selected channel at full fidelity.
