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.
