Systems and devices for providing multiple video signals simultaneously to an end user. Multiple video tuners are each tuned to a different video signal at a content provider's location. The output of each tuner is then received by a video multiplexer which multiplexes the disparate video signals into a single composite video signal. The resulting composite video signal, which presents the different video signals in a grid pattern with each sector in the grid phoning a different video signal, is then provided with a suitable user interface. The user interface provides such information such as the source of each of the video signals and allows an end user to navigate between the different video signals. The resulting composite video signal with its user interface, is then encoded and transmitted to an end user device by way of a network. An end user, using the end user device, can therefore simultaneously view multiple video signals without the need for switching channels.
