Systems and methods for delivering picture-in-picture signals at diverse compressions and bandwidths
First Claim
1. A system for providing picture-in-picture, at a user display device, the system comprising:
- a first video signal and a second video signal;
a transmission device, wherein the transmission device includes a selector interface for receiving a selector signal, and a video interface for receiving the first video signal and the second video signal;
wherein the transmission device includes a video output, wherein the video output includes a first video output signal at a first compression and a first bandwidth, and a second video output signal at a second compression and a second bandwidth, and wherein the transmission device further includes a compositing device for combining the first and second video output signals into a composite signal for display at the user display device;
wherein the first video output signal is derived from the first video signal, and the first compression and the first bandwidth is based at least in part on the selector signal;
wherein the second video output signal is derived from the second video signal, and the second compression and the second bandwidth is based at least in part on the selector signal; and
wherein the combined first and second video output signals are displayed at the user display device as the composite signal without the use of multiple tuners at the user display device.

Abstract
T Systems and methods for providing picture-in-picture, or other multi-picture displays. Some of the systems include two or more video and/or data signals that are coupled to a transmission device. In addition, a selector signal is coupled to the transmission device. The transmission device also includes a video output that, based at least in part on the selector signal, provides a derivative of one of the video and/or data signals at a first compression and bandwidth, and the other video and/or data signal at a second compression and bandwidth. Various of the methods include utilize the systems to transmit two or more video outputs based at least in part on a selector signal.

13. A method for supporting picture-in-picture, the method comprising:
-
receiving a first video signal, a second video signal, and a selector signal; decoding the selector signal, wherein the selector signal indicates that the first video signal is a main-screen video signal, and the second video signal is a sub-screen video signal; and based at least in part on the decoded selector signal, formatting the first video signal as a high bit rate video signal, and the second video signal as a low bit rate video signal; and transmitting the high bit rate video signal and the low bit rate video signal over as a composite signal over a transmission medium coupled to a NID; and displaying the composite signal at a user display device coupled to the NID. - View Dependent Claims (14, 15, 16, 17, 18, 19)
