Embodiment Construction

[0013]The preferred embodiments of the disclosure now will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the disclosure include systems and methods that provide an interactive session with a user to determine the characteristics of a television set or other display device coupled to a digital home communication terminal (DHCT).

[0014]Video formats can vary in picture size, frame rate, and on whether pictures are progressive or interlaced. A progressive picture constitutes all the lines of a frame whereas an interlaced picture has a top field and bottom field of alternating lines to constitute a complete frame. An interlaced picture is displayed during respective field intervals. Video formats can further vary in other attributes or characteristics such as color format, color primaries, picture width-to-height aspect ratio, and width-to-height aspect ratio of the individual picture elements, or pixels, that make-up the pi...

Abstract

A system and method for determining the characteristics of a device coupled to a client device are disclosed. A method, according to one embodiment, includes driving a display device with a first video output signal formatted according to a first video interface specification; responsive to driving the display device, soliciting user input based on information included in the first video output signal; determining a characteristic of the display device based on the user input; and driving the display device according to the determined characteristic.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a divisional of U.S. patent application Ser. No. 10 / 761,777, filed on Jan. 21, 2004, which is incorporated by reference herein in its entirety.TECHNICAL FIELD[0002]This disclosure relates in general to the field of television systems, and more particularly, to the field of interactive television.BACKGROUND OF THE DISCLOSURE[0003]With recent advances in digital transmission technology, subscriber television systems are now capable of providing much more than the traditional analog broadcast video. In implementing enhanced programming, the home communication terminal (“HCT”), otherwise known as the set-top box, has become an important computing device for accessing content services (and content within those services) and navigating a user through a maze of available services. In addition to supporting traditional analog broadcast video functionality, digital HCTs (or “DHCTs”) now also support an increasing number of two-w...
