Claim:
1. A method of providing a program guide service based on HTML in a broadcasting terminal, the method comprising: receiving a start request of the program guide service from a user; outputting, by a microprocessor of the broadcasting terminal, a start page according to the received start request by executing a container in an HTML start page resource to generate a first key handler for processing a key event inputted by the user; receiving a menu request to navigate a menu of the program guide service from the user; and outputting, by the microprocessor, at least one menu page for navigation of the menu according to the received menu request by executing a context in at least one menu page resource, wherein each of the start page and the at least one menu page has a different resource address, a life cycle of the at least one menu page is managed by the first key handler, the executing of the context generates a second key handler for processing the key event delivered from the first key handler, and when the key event is inputted by the user, the container determines an element for processing the inputted key event, and processes directly the inputted key event using the first key handler or delivers the inputted key event to a context of a corresponding menu page based on the determined element for processing the inputted key event.
