Abstract: An electronic device with one or more processors, memory and a display receives a first request to display a first video stream that corresponds to a first channel. In response to receiving the first request, the device starts to download the first video stream from a content source for the first video stream. After starting to download the first video stream, the device displays the first video stream and starts to preload one or more video streams including a second video stream that corresponds to a second channel that is adjacent to the first channel. While displaying the first video stream, the device receives a second request to display the second video stream. In response to receiving the second request, the device displays at least a portion of the second video stream using a preloaded portion of the second video stream.
