Patent ID: 8334929

Claim:
A signal processing apparatus, comprising: an input section configured to take a video signal in accordance with a first transmission standard supporting a single link or a video signal in accordance with a second transmission standard supporting a dual link, the first transmission standard allowing 2-channel interlaced video signals to be transmitted sequentially in parallel on a field by field basis, the second transmission standard allowing progressive video signals to be divided into field signals for odd scanning lines and field signals for even scanning lines, and allowing the two types of field signals to be transmitted sequentially in parallel; a storage section configured to store the video signal inputted to said input section; first and second signal processing sections configured to subject the video signal stored in said storage section to a filtering process in an orthogonal direction with respect to the scanning lines, using processing circuits with an identical structure in parallel; and a control section configured to control supply of the video signal from said storage section to said first and second signal processing sections, wherein when the video signal in accordance with the first transmission standard has been inputted to said input section, said control section performs control for causing the 2-channel interlaced video signals to be superimposed on a unit image by unit image basis and stored in said storage section, dividing the video signal stored in said storage section at each boundary between adjacent unit images, and supplying each of the 2-channel interlaced video signals to a corresponding one of said first and second signal processing sections, and when the video signal in accordance with the second transmission standard has been inputted to said input section, said control section performs control for causing the progressive video signals to be superimposed on a unit image by unit image basis and stored in said storage section, dividing the video signal stored in said storage section at every other boundary between adjacent unit images, and supplying the field signals for the odd scanning lines and the field signals for the even scanning lines to said first and second signal processing sections, respectively; and two field to frame conversion sections configured to convert field images into frame images in parallel, in connection with the two signals subjected to the signal processing by said first and second signal processing sections, respectively, wherein, only when the video signal in accordance with the first transmission standard has been inputted to said input section, said control section performs control for causing the two signals subjected to the signal processing by said first and second signal processing sections, respectively, to be supplied to said field to frame conversion sections.
