Picture-in-Picture
(PIP) Controller
The MC44463 Picture–In–Picture (PIP) controller is a low cost member of
a family of high performance PIP controllers and video processors for
television. It is a follow–up to the MC44461 PIP, in which two additional
modes of operation have been added. A replay mode is provided, which
captures several seconds of the main picture for replay in four different
speeds. The capture time is programmable in four resolutions (ratio of
captured fields to total fields), which trade the number of fields captured to
the length of replay time. The second additional mode provides for multiple
small picture overlays from a second non–synchronized source. The number
of PIP images is 3 for the 1/9 screen area and 4 for the 1/16 screen area.
Like the MC44461 this is NTSC compatible, I2C bus controlled and available
in the 56–pin shrink dip (SDIP) package.
The main features of the MC44463 are:
• Three PIP Functional Modes: Standard Single Active PIP Mode, Up to 8
Seconds of Capture and Replay Mode, and a 3 or 4 Multiple PIP Mode –
Vertical Stacked with 1 Active at Any One Time
• 4 Capture Resolutions – 1 out of 10, 1:8, 1:6, 1:4. 4 Playback Speeds =
1 Times Acquire Speed; 1/2; 1/4; 1/8
• Full 2 Frame Store for the Single PIP Removes the Rolling
Store/Playback Memory Interference – “Joint Line”
• External Memory for Replay and Multiple Modes: 4 Meg and 16 Meg
• Two NTSC CVBS Inputs – Switchable Main and PIP Video Signals
• Single NTSC CVBS Output Allows Simple TV Chassis Integration
• Two PIP Sizes; 1/16 and 1/9 Screen Area – Freeze Field Feature
• Variable PIP Position in 64–X by 64–Y Steps
• PIP Border with Programmable Color
• Programmable PIP Tint and Saturation Control
• Automatic Main to PIP Contrast Balance
• Vertical Filter
