Method of and apparatus for simultaneously displaying video input along with supplementary information

An apparatus for simultaneously displaying a video input along with supplementary information, comprising:

• a video overlay device, and a network management module, a removable storage device and a display device coupled to the video overlay device,
• wherein the network management module comprises a computer or a cloud server for uploading, via network, and controlling supplementary information;
• wherein the video overlay device comprises a central processing unit, and a video input processing unit, a video output processing unit and local memory coupled to the central processing unit, wherein, under a control of the central processing unit, the supplementary information is obtained from the network management module, an email sent from the network management module, or removable storage devices, and is subsequently stored in the local memory, wherein the supplementary information comprises content information, layout information, and playback information;
• and
• wherein in operation, a video input is converted by the video input processor device into an input digital signal that is subsequently stored within the local memory, wherein the input digital signal and the content information of the supplementary information read from the local memory is relayed to the video output module and superimposed according to the layout and playback information of the supplementary information, and wherein the superimposed digital signal is converted by the video output module into a video signal that is transmitted to the display device for display.
