Abstract: An apparatus and method for producing TV advertising contents and inserting interstitial advertisements on TV programs which is primarily used to interstitially insert the DIY audio, video, graphics, and texts onto ordinary TV programs, where the Data Storage Unit can record these audio/video and graphic/text data of ad contents. Users can store pictures and sounds captured by digital cameras or digital camcorders in the Data Storage Unit. The data of audio/video and graphic/text stored in the Data Storage Unit can be provided to the Video and Graphics Processing Unit for blending or overlaying, and be incorporated into the TV programs that are transferred from the Audio and Video Input Unit. The way to incorporate video for broadcasting includes to broadcast with two (or more than two) pictures (the pictures from Data Storage Unit and the picture of TV programs) blended, and to broadcast with Picture-in-Picture (PIP) overlay.
