Method of contents cache control in a BML/HTML integrated browser [digital TV application]

We have developed a new method of contents cache control to improve performance of response to user operations in a BML/HTML integrated browser on digital TV. By using our method, our browser can use as much memory as possible for the contents cache without causing a lack of memory when other applications start, and it can pre-fetch data which viewers might wish to watch. We have shown from our experiments that our method is effective.
