7.2.1 Comb filter operation
7.2.2 Automatic color standard detection
7.2.3 Easy CVBS versus Y/C discrimination
7.2.4 Stability of vertical synchronization
Super-adaptive
separation for:
The decision logic of the 2-dimensional comb filter in the SAA7154E; SAA7154H is
improved in order to reduce residual artifacts (namely cross-color and cross-luminance
(dots)). The bandwidth of the combed luminance and chrominance signals are kept
(compared to the SAA7118), such that the overall performance is significantly enhanced.
The result of the automatic color standard detection can be read through I
access; the level of detail of the respective status bits includes subcarrier frequency, line
frequency and field frequency.
Thus all PAL, NTSC and SECAM standards including sub-standards can be distinguished:
Remark: For NTSC-Japan there is no detection of black level offset through color
standard detection.
The SAA7154E; SAA7154H checks respective channels (under control of firmware) for
the actual burst amplitude and writes the result to dedicated I
Comparing the actual amplitudes enables the system firmware to determine either a
CVBS or s-video input.
Stability of vertical synchronization has been improved considerably:
Deteriorated signals from VCR tapes might upset the vertical synchronization, resulting in
vertical jumping of the displayed picture during pause or even during playback mode.
When switching from playback mode to fast forward, the output picture is sensitive to
scrolling which requires a certain time until it is stable again.
