Design And Implementation Of A Web Browser On Digital TV Set-top Box

Digital Television is the television system that transports, receives, processes, records, and controls TV signals all in digital format. Its outstanding makes itself developing quickly. And also a Digital TV industry is now coming into being. However, many problems occur in the industrializing progress. For example, the interactive service that Digital TV Set-top Box can provide is less than expected now. While at the same time, those large communication enterprises, both domestic and international together with those internet SPs are developing IPTV at a high speed. What's more, they have already got benefit from that. So working on to enhance the set-top box's interactive function is of importance and value.This paper implements a web browser on Broadcom's BCM97115 digital TV set-top box resolution. The successful implementation of the web browser is a try to develop the Set-top box's network functions. BCM97115 is a single-chip digital TV resolution that supports DVB-C. It provides a 10/100M Ethernet interface. Embedded Linux is its operation system.This paper creatively proposes a way to implement a web browser on the set-top box. The structure of the web browser has been designed. And the net interface, XML parser and the control part are programmed with C++. After a set of experiments and analysis, the web browser's function and its out-looking are given in the final.
