INPUT STREAM CONVERSION AND PROGRAMMABLE VOLTAGE REGULATOR FOR +5V POWER SIGNAL
A grand central architecture for an all-in-one consumer electronics (CE) media device may include a single IR/RF/Microphone handheld remote control for controlling and/or displaying information for all CE devices of a user(s) in concert with the all-in-one CE media device (e.g., a media player) operative for playback of one or more media formats including but not limited to optical discs, audio and/or video, images, music, files, streaming media content, stored media content, and other content. The all-in-one CE media device may include an enable/disable +5V power signal triggered by an enable input for a HDMI interface that may bridge HDMI source devices and sink devices. The all-in-one CE media device may wirelessly communicate RF signals to one or more speakers/transducers that either include their own dedicated internal or external power amplifiers, and may wirelessly communicate with one or more microphones and/or speakers and apply algorithms for optimizing audio quality.
