A multi-host endpoint reflector enables a method of communication between multiple USB hosts through the USB devices connected to them, where data from one USB host is routed across the USB devices between endpoints of complimentary directions to one or more additional USB hosts. The multi-host endpoint reflector may be integrated with a USB hub controller to form a USB compound device to create a multi-host endpoint reflector hub. A USB multi-host endpoint reflector hub enables a USB OTG B device to become a host upon request by providing a data bridge between the OTG B device after it has transitioned to a host role while any other OTG A device that already is a host is not required to change its host role to a slave role. Therefore a plurality of OTG host devices may co-exist on the same interconnection system hub and communicate there between.

A system, circuit and method are provided herein for reducing perceived flicker in video images transmitted using compression and bit rate control. According to one embodiment of the method, a parameter used in the video compression scheme is stored. The parameter stored is one that is subject to adjustment during normal operation of the video compression scheme. Compressed video frame data issued by a compression encoder is used to test for a still-picture condition. When a still-picture condition is detected, the value of the parameter used by the video compression scheme is fixed to the stored value for the duration of the still-picture condition. An embodiment of the system includes an encoder, buffer, bit rate controller, and flicker reduction circuit. An embodiment of the flicker reduction circuit includes a still-picture detection circuit operably coupled to a compressed data path beginning at the output of the encoder.
