SAA7134HL
PCI audio and video broadcast decoder
Comb filtering achieves higher luminance bandwidth, resulting in sharper picture and
detailed resolution. Comb filtering further minimizes color crosstalk artifacts, which would
otherwise produce erroneous colors on detailed luminance structures.
The comb filter as implemented in the SAA7134HL is adaptive in two ways:
Adaptive to transitions in the picture content
Adaptive to non-standard signals (e.g. VCR)
The integrated digital delay lines are always exactly correct, due to the applied unique
line-locked sampling scheme (LLC). Therefore the comb filter does not need to be
switched off for non-standard signals and remains operating continuously.

Macrovision detection
The SAA7134HL detects if the decoded video signal is copy protected by the Macrovision
system. The detection logic distinguishes the three levels of the copy protection as
defined in rev. 7.01, and are reported as status information. The decoded video stream is
not effected directly, but application software and Operation System (OS) has to ensure
that this video stream maintains tagged as ‘copy protected’, and such video signal would
leave the system only with the reinforced copy protection. The multi-level Macrovision
detection on the video capture side supports proper TV re-encoding on the output point,
e.g. by Philips TVencoders SAA712x or SAA7102.
6.6.6
Video scaling
The SAA7134HL incorporates a filter and processing unit to downscale or upscale the
video picture in the horizontal and vertical dimension, and in frame rate
(see
Figure 9
and
Figure 10
). The phase accuracy of the re-sampling process is
1
64
of the
original sample distance. This is equivalent to a clock jitter of less than 1 ns. The filter
depth of the anti-alias filter adapts to the scaling ratio, from 10 taps horizontally for scaling
ratios close to 1 : 1, to up to 74 taps for an icon sized video picture.
Most video capture applications will typically require for downscaling. But some zooming
is required for conversion of ITU sampling to SQuare Pixel (SQP), or to convert the
240 lines of an NTSC field to 288 lines to comply with ITU-T video phone formats.
The scaling acquisition definition also includes cropping, frame rate reduction, and defines
the amount of pixels and lines to be transported through DMA over the PCI-bus.
Two programming pages are available to enable re-programming of the scaler in the
‘shadow’ of the running processing, without holding or disturbing the flow of the video
stream. Alternatively, the two programming pages can be applied to support two video
destinations or applications with different scaler settings, e.g. firstly to capture video to
CPU for compression (storage, video phone), and secondly to preview the picture on the
monitor screen. A separate scaling region is dedicated to capture raw VBI samples, with a
specific sampling rate, and be written into its own DMA channel.
