ATV Demod
More fixes concerning horizontal and vertical sync. Enhancement so that horizontal sync process does not make the image slowly drift you can now expect a steady image. It should also conform the 625 and 525 standards. Other values are non standard but follow the same rules. Various code optimizations should save about 10% processing power.
Channel Analyzer
Optimized the log2 decimation so that half-band decimators are used more efficient than the rational decimator. A rational decimator does the last mile when the rational downsampler is engaged. Rational decimator filtering parameters have been fixed also so stray input from out of band signals should now be suppressed.
