Abstract: Systems and methods are described for streaming media content. A first portion of a media content item is received at a bandwidth available to a user device, wherein the quality of the first portion is based on the bandwidth available. A second portion of the media content item is received at a decreased or increased bandwidth, wherein the quality of the second portion is based on the increased or decreased bandwidth available to the user device. The quality of the first portion and the second portion is determined. In response to determining that the quality of the second portion received at the decreased bandwidth is less than a quality threshold, the quality of the first portion of the media content item is reduced prior to sending the first portion to a playback buffer.

Abstract: A video transmission system includes a transceiver module that transmits a video signal to a remote device over at least one communications channel wherein the video signal is transmitted as at least one separate video layer stream chosen from, an independent video layer stream and at least one dependent video layer streams that require the independent video layer for decoding. A control module determines at least one channel characteristic of the at least one channel and chooses the at least one separate video layer stream based on the at least one channel characteristic of the at least one channel.

Abstract: Circuitry separates a modulation signal into digital sign and magnitude signal components. The digital magnitude signal is converted to an analog magnitude signal. The analog magnitude signal is the mixed with an in-phase or quadrature carrier signal under the influence of the digital sign signal and routed to a driver output stage.
