The Figure 12 shows a detailed block diagram of the input processing blocks. The input
signal can be vertically and horizontally compressed or horizontally expanded by a large
number of factors. Furthermore the input signal can be processed by different noise
reduction algorithms to reduce the noise in the signal. The noise measurement block
determines the noise level of the input signal. The letter box detection block finds the
start and end line of letter box pictures. The information can be used by a µC to calculate
zooming factors and to control the IC for resizing the picture for a full screen display on
16:9 tubes.
Figure 12
The different blocks and the corresponding I²C Bus parameters will be described now in
more detail.
