Abstract: A multicolor electronic display is based on an array of luminescent semiconductor nanocrystals. Nanocrystals which emit light of different colors are grouped into pixels. The nanocrystals are optically pumped to produce a multicolor display. Different sized nanocrystals are used to produce the different colors. A variety of pixel addressing systems can be used.

Abstract: A method of providing television content includes receiving a channel selection at a television and determining whether the selected channel is provided within a user-defined multi-channel analog stream from a set top box. The multi-channel analog stream can include one hundred and twenty five user selected channels. Further, the user-defined multi-channel analog stream is created from a digital satellite signal. The television can be tuned to the channel after determining that the channel is provided within the user-defined multi-channel analog stream. The method includes determining whether the television is serviced by the set top box. A satellite signal is decoded for the channel at the set top box after determining that the channel is not provided within the user-defined multi-channel analog stream and after determining that the television is serviced by the set top box. A single channel signal associated with the channel can be transmitted to the television.
