The convergence of computer, communication and entertainment is driving cable, telco, hardware and software firms to attempt control over a new future gateway to the home -- the set top box. This raises the question of the ease of access to competing services, standards for interoperability and the freedom to purchase devices.

Technology is fast enabling set-top boxes to handle a variety of tasks like interactive video, telephony, home security, banking and on-line services. The ability of distribution media like cable, telephone lines and satellite dishes to be connected simultaneously is part of the future. The set-top box will support the "intelligent agents" that guides users through the maze of choices. The set-top industry may itself develop into a mediating force as technology and rules governing interconnection develop. This race to define the personality and functionality of future set-top boxes has begun.
