1. Introduction
The QVCP (Quality Video Composition Processor) is a high-resolution image
composition and processing pipeline that facilitates both graphics and video
processing. In combination with several other modules, it provides a new generation
of graphics and video capability, far exceeding the older standards. QVCP provides
its advanced functionality using a series of layers and mixers; a series of display-data
layers (pixel streams) are created and logically mixed in sequence to render the
composite output picture.
The PNX15xx Series hosts one QVCP module. The display processor (QVCP)
contains a total number of two layers and is mainly intended to be connected to a TV,
a monitor or an LCD panel. Due to the independence of the layers, a number of
different scenarios is possible. However, in general, the QVCP has been designed to
mix one video plane and one graphic plane. It can therefore be used to display a fully
composited video image consisting of PIP(s), menu(s), and other graphical
information.
In this document, the words surface or plane are used to replace layer depending on
the context.
QVCP supports a whole range of progressive and interlaced display standards: for
televisions, from standard-definition resolutions such as PAL or NTSC to all eighteen
ATSC display formats such as 1080i or 720p, and for computer and LCD displays,
from VGA to W-XGA resolutions at 60 Hz. The wide variety of output modes
guarantees the compatibility with most display-processor chips.
In order to achieve high-quality video and graphics as demanded by future consumer
products, a number of complex tasks need to be performed by the QVCP. The main
functions of the video and graphics output pipeline are listed below:
