SAF7115

Multistandard video decoder

I Independent Brightness Contrast Saturation (BCS) - adjustment for decoder part

I User programmable sharpness control

I Detection of copy protected input signals:

N According to Macrovision standard

N Indicating the level of protection

I Automatic TV/VCR detection

I 10-bit wide video output at comb ﬁlter video decoder

I X-port video output either as:

N Noise shaped 8-bit ITU-656 video or

N Full 10-bit ITU-656 interface (DC-performance 9-bit)

2.3 Video scaler

I Horizontal and vertical down-scaling and up-scaling to randomly sized windows

I Horizontal and vertical scaling range: variable zoom to 1/64 (icon) (note: H and V

zoom are restricted by the transfer data rates)

I Vertical scaling with linear phase interpolation and accumulating ﬁlter for anti-aliasing

(6-bit phase accuracy)

I Conversion to square pixel format

I Generation of a video output stream with improved synchronization grid at the I-port

I Two independent programming sets for scaler part, to deﬁne two regions (e.g. for

different scaling for VBI and active picture) per ﬁeld or sequences over frames

I Fieldwise switching between decoder part and expansion port (X-port) input

I Brightness, contrast and saturation controls for scaled outputs

2.4 VBI data slicer

I Versatile VBI-data decoder, slicer, clock regeneration and byte synchronization, e.g.:

N WST525/WST625 (CCST)

N VPS

N US/European Close Caption (CC)

N WSS525 (CGMS), WSS625

N US NABTS

N VITC 525/VITC 625

N Gemstar 1x

N Gemstar 2x

N Moji

I I2C-bus read-back of the following decoded data types:

N US Close Caption (CC)

N European Close Caption (CC)

N WSS525 (CGMS)

N WSS625 (CGMS)

N Gemstar 1x

N Gemstar 2x
