Abstract: A system, method, and apparatus for providing display parameters from the decode process to the display process are presented herein. The decode process receives images which are encoded according to a predetermined standard. Included with the encoded images are parameters which facilitate the decode and display processes. The decode process decodes the encoded images as well as the parameters and stores each image in a separate image buffer.

Abstract: Methods and systems for wireless communication are disclosed and may include band-limiting a wireless signal utilizing a programmable bandpass filter, generating a first signal by undersampling utilizing a clock signal and generating a second signal by undersampling the signal utilizing a delayed version of the clock signal, which may then be subtracted from the first signal. The filter may comprise a microstrip or a coplanar waveguide bandpass filter. The delay may be variable, and may be defined as an inverse of a frequency difference between the desired channel and a blocker signal. The bandwidth of the filter may be centered at the desired channel. The clock signal may be generated at a frequency which may be an integer sub-harmonic of the desired channel, and may be greater than twice a bandwidth of the filter. The delay may be controlled by a programmable delay circuit, which may comprise CMOS inverters.

Abstract: Aspects of a method and system for low power IDLE signal transmission in Ethernet networks are provided. In this regard, during time periods between transmissions of actual data by a local Ethernet link partner, the local Ethernet Link partner may generate one or more signals, in place of a standard Ethernet IDLE signal, that enable synchronization between Ethernet link partners. In this manner, the generated signals may enable reducing power consumption as compared to standard Ethernet IDLE signals. Accordingly, link activity may be monitored to enable detecting periods when there may be no actual data for transmission and the generated signals may be transmitted. The generated signals may be transmitted at a reduced symbol rate as compared to standard Ethernet IDLE signals. The generated signals may be transmitted via fewer network links as compared to standard Ethernet IDLE signals.
