A smart universal remote control based on audio-visual device virtualization

With the rapid development of home network technology, sharing multimedia content among AV devices has become easier, however, the operation of these AV devices have become more complicated. These devices display status and related information through on-screen display (OSD) or liquid crystal display module (LCM) display, but the displays have some issues with OSD interference to reception or require users to understand all the symbols on the LCM display. This paper proposes a universal remote control based on AV device virtualization, called V-URC (virtualization based universal remote control), in order to control AV devices V-URC dynamically generates user interfaces, which conform to the current state of devices; this not only simplifies the operation of AV devices, but also eliminates the issues caused by LCM display and OSD-based AV devices In addition, for new AV devices, V-URC can be used directly without the need to go through complicated learning programs or update of firmware.
