    1111Some Internet video content is only available for streaming: the receiver downloads a small part of the video at a time, and the entire video is never saved on the device.

    18 In !streamload, the base layer of the video is streamed in real time, and enhancement layers may be downloaded ahead of time. The video quality is improved because the receiver can take advantage of available bandwidth to download enhancement layers of future chunks of video, "smoothing" the effect of variations in signal quality. However, the legal requirements of streaming are satisfied because the video that is downloaded to the device cannot be played without the base layer (which is streamed).
