Abstract
Abstract A wide aspect ratio screen color television system, such as a 16:9 aspect ratio screen television system, includes a signal generating circuit for generating the wide aspect ratio screen color television signal with a predetermined two-dimensional frequency band, a screen separating circuit for separating the color television signal into at least a first television signal relating to a relatively narrow aspect ratio portion and second television signal relating to an excess portion thereover, a circuit for eliminating a prescribed high frequency region of the two-dimensional frequency band of the first television signal, a signal suppressing circuit for suppressing the frequency band of the second television signal and a signal multiplexing circuit for multiplexing the suppressed second television signal onto the two-dimensional high frequency band region in place of the eliminated portion of the first television signal.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
A color television system comprising: means for generating a wide aspect ratio screen color television signal with a predetermined two-dimensional frequency band; means for separating the color television signal into at least a first television signal relating to a relatively narrow aspect ratio and a second television signal relating to an excess portion thereover, said first television signal having a high frequency region and a low frequency region and said second television signal having a high frequency region and a low frequency region; means for eliminating a prescribed portion of said high frequency region of the two-dimensional frequency band of the first television signal to obtain a resulting signal; means for time expanding both the high and low frequency regions of the second television signal; means for suppressing the frequency band of both the high and low frequency regions of the second television signal; means for multiplexing the suppressed second television signal onto the two-dimensional resulting signal and low frequency region of said first television signal; and means for motion adapted processing of the low frequency region of the first television signal.
Claim 2
Dependent Claim
182 words
A color television system comprising: means for generating a wide aspect ratio screen color television signal with a predetermined two-dimensional frequency band; means for separating the color television signal into at least a first television signal relating to a relatively narrow aspect ratio and a second television signal relating to an excess portion thereover, said first television signal having a high frequency region and a low frequency region and said second television signal having a high frequency region and a low frequency region; means for eliminating a prescribed portion of said high frequency region of the two-dimensional frequency band of the first television signal to obtain a resulting signal; means for time expanding both the high and low frequency regions of the second television signal; means for suppressing the frequency band of both the high and low frequency regions of the second television signal; means for multiplexing the suppressed second television signal onto the two-dimensional resulting signal and low frequency region of said first television signal; and means for motion adapted processing of the low frequency region of the first television signal.
Claim 3
Dependent Claim
57 words
The system of claim 1 wherein said means for motion adapted processing includes: static-image processing means for outputting a first signal; moving image processing means for outputting a second signal; folding noise detecting means for generating a detection signal; and selecting means for selecting one of the first and second signals in response to said detection signal.
Claim 4
Dependent Claim
15 words
The system of claim 2 wherein said moving image processing means includes field thinning means.
Claim 5
Dependent Claim
203 words
A color television system comprising: means for generating a wide aspect ratio screen color television signal with a predetermined two-dimensional frequency band; means for separating the color television signal into at least a first television signal relating to a relatively narrow aspect ratio portion and second television signal relating to an excess portion thereover, said first television signal having a high frequency region and a low frequency region and said second television signal having a high frequency region and a low frequency region; means for eliminating a prescribed portion of said high frequency region of the two-dimensional frequency band of the first television signal to obtain a resulting signal; means for time expanding both the high and low frequency regions of the second television signal; means for suppressing the frequency band of both the high and low frequency regions of the second television signal; means for separating the second television signal into vertical high frequency and vertical low frequency signals and orthogonally modulating the vertical high frequency and vertical low frequency signal to obtain a combined orthogonally modulated signal; and means for multiplexing the suppressed combined orthogonally modulated signal onto the two-dimensional resulting signal and low frequency region of said first television signal.
Claim 6
Dependent Claim
