Abstract
Abstract A home theater comprises a video processing sub-system and a PC capable of controlling the sub-system. The sub-system has a de-interlacer/line doubler and the PC has a graphics controller with scaling capability. The combination of the line doubler and the scaler is made to function as a line quadrupler.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
99 words
An information processing system comprising: a video sub-system with a line multiplication device for processing video data so as to increase a number of lines in the video data in a vertical direction; a graphics controller, operably coupled to the line multiplication device, that is configured to receive the video data with the increased number of lines from the line multiplication device, the graphics controller including a scaler that is configured to further increase the number of lines in the video data, and wherein the line multiplication device and the graphics controller are operable substantially independent of each other.
Claim 2
Dependent Claim
99 words
An information processing system comprising: a video sub-system with a line multiplication device for processing video data so as to increase a number of lines in the video data in a vertical direction; a graphics controller, operably coupled to the line multiplication device, that is configured to receive the video data with the increased number of lines from the line multiplication device, the graphics controller including a scaler that is configured to further increase the number of lines in the video data, and wherein the line multiplication device and the graphics controller are operable substantially independent of each other.
Claim 3
Dependent Claim
35 words
The system of claim 1 , wherein: the line multiplication device includes an input for receiving interlaced video input data, and the video data with the increased number of lines comprises de-interlaced video output data.
Claim 4
Dependent Claim
18 words
The system of claim 2 , wherein the graphics controller is controllable to supply interlaced video output data.
Claim 5
Dependent Claim
25 words
The system of claim 3 , wherein the graphics controller is controllable to supply the interlaced video output data by vertically shifting a same field.
Claim 6
Dependent Claim
15 words
The system of claim 1 , wherein the line multiplication device comprises a line doubler.
Claim 7
Dependent Claim
48 words
The system of claim 1 , wherein the line multiplication device doubles the number of lines in the video data, and the graphics controller doubles the doubled number of lines from the line multiplication device, thereby providing a quadrupling of the number of lines in the video data.
Claim 8
Dependent Claim
25 words
The system of claim 6 , wherein the line multiplication device doubles the number of lines in the video data by de-interlacing the video data.
Claim 9
Dependent Claim
26 words
The system of claim 1 , wherein the system is further configured to selectively provide an output from either the video sub-system or the graphics controller.
Claim 10
Dependent Claim
30 words
The system of claim 8 , wherein the system is further configured such that a failure of the graphics controller effects a selection of the video sub-system as the output.
Claim 11
Dependent Claim
17 words
The system of claim 1 , further including a personal computer (PC) that comprises the graphics controller.
