Reception of digital multimedia data signals from multiple sources in a stream over a fixed bandwidth communications path may be accomplished by subscribing to a base layer of a first source and a base layer of a second source, and subscribing to an enhancement layer of the first source. Data signals corresponding to the subscribed layers of the first and second sources may be received in a stream over the fixed bandwidth communications path, output signals may be produced which correspond to the received data signals for the first source, and output signals may be produced corresponding to the received data signals for the second source. The output signals for the first source may be displayed in a first portion or window of a display, and output signals for the second source may be simultaneously displayed in a second portion or window of the display, thereby providing a picture-in-picture (PIP) display for streaming digital video.
A method of receiving digital multimedia data signals from multiple sources in a stream communicated over a fixed bandwidth communications path comprising:
An article comprising a machine readable medium having a plurality of machine readable instructions, wherein when the instructions are executed by a processor the instructions subscribe the processor to receive a first layer of a first source, a first layer of a second source, and a second layer of the first source, control the reception of data signals corresponding to the subscribed layers of the first and second sources in a stream over a fixed bandwidth communications path, produce output signals corresponding to the received data signals for the first source and the second source, display the output signals for the first source in a first portion of a display, substantially simultaneously display the output signals for the second source in a second portion of the display, unsubscribe the second layer of the first source, and to subscribe the processor to a second layer of the second source.
A method of streaming digital multimedia data signals of multiple sources from at least one server system in a layered stream over a fixed bandwidth communications path in a network to a client system comprising:
An article comprising a machine readable medium having a plurality of machine readable instructions, wherein when the instructions are executed by a processor of a client system the instructions subscribe the client system to base layers of multiple sources of multimedia data, subscribe the client system to an enhancement layer of a selected one of the sources, control the reception of the base layers and the enhancement layer in a layered stream over a fixed bandwidth communications path at the client system, display the base layer and the enhancement layer of the selected source in a first portion of a display of the client system, display the base layer of at least one non-selected source in at least one other portion of the display, unsubscribe the enhancement layer of the selected source and subscribe to an enhancement layer of a newly selected source.
