The video link concept is a proposed method for providing video codec service to the customer base in a manner similar to the way phone service is provided today. Three possible implementations are low volume solutions that could be used to test market the video link concepts. The third method, which is technically superior to the first two, would only be economically feasible in a high volume implementation.
