GENERAL DESCRIPTION
The SAB9075H is a picture-in-picture controller for the NTSC environment in combination with the Integrated NTSC decoder and sync processor TDA8315.
The device inserts one or two live video channels with reduced sizes into a live video signal. All video signals are expected to be analog baseband signals. The conversion into the digital environment and back to the analog environment is carried out on-chip. Internal clocks are generated by two PLLs.
Due to the two PIP channels and a large external memory, a wide range of PIP modes are offered. The emphasis is put on double-PIP and multi-PIP modes. In combination with the different border colours and some external software the IC concept can be used as an excellent channel selection tool.

Some of the I
C-bus registers are for controlling the saturation and HUE of the colours. There are also outputs for the mute function of main and sub-channel.

FUNCTIONAL DESCRIPTION Acquisition area
The acquisition area is in the centre of the visible screen area. Vertically 228 lines are sampled. Horizontally 672 Y-pixels are processed. The exact active processing area can be fine tuned in horizontal (2 pixels/steps, 16 steps) and vertical (1 line/step, 16 steps) direction for both main and sub-channel by the I
2
C-bus (see Fig.3). The given numbers are pixel numbers at a 13.5 MHz data rate. The signals, which are dependent on the I2C-bus registers, can also be related to the H
, in which event they are
sync
delayed by 68 pixels.
Chrominance format
The chrominance format is 4:1:1. The YUV signals are sampled at a rate of 27 MHz and then
filtered and subsampled to a data rate of 13.5 MHz.

It is expected that the input signals do not contain frequencies outside the video bandwidth (Y
= 4.5 MHz;

Display area
The display area is shown in Fig.4. The given numbers are pixels at a data rate of 13.5 MHz. The signals are related to the burstkey and the V registers the signals can also be related to the H

The internal 13.5 MHz data rate is upsampled to the double frequency (27 MHz) and then fed to the DACs.

The display output can be fine positioned by the I

PIP modes
The controller contains two independent acquisition-channels which provide the scaling factors to support the range of different modes. With the external memory of 2 Mbit it is possible to select between single, double and multi-PIP modes.
Table 2 gives an overview of the different PIP modes.

Notes
1. The given sub/main sizes are visible PIP sizes, a border is drawn around these PIPs and does not influence these sizes. The size of the border is 4 pixels wide and 2 lines/fields high.
2. The SAB9075H can be set in automatic mode in which the reduction factors are automatically set by the mode select and aspect ratio select bits of the I
2
C-bus. If the automatic mode is switched OFF the reduction factors can be set
manually. This will give more flexibility to adjust the aspect ratios of incoming signals.
PIP positions
The positions are graphically depicted in Figs 5 to 17.
