The LVP603 is an LED Video Processor designed for various video display applications, particularly with LED screens. It functions as a central unit for processing and outputting video signals, offering a range of input and output options, as well as features for image manipulation and display management.

Function Description:

The primary function of the LVP603 is to process multiple video input signals and output them to LED display devices. It supports a variety of input sources, including composite video, VGA, DisplayPort (DP), DVI, and HDMI, allowing for flexibility in connecting different types of video equipment. The processor can handle up to 6-channel signal input and 4-channel stereo audio input, with audio switching synchronized to video input selection.

A key feature of the LVP603 is its ability to perform seamless or fading in/out switching effects between different video input signals, categorized into three groups (V1, V2; VGA; DP, DVI, HDMI). This ensures smooth transitions without flickering, trembling, stasis, delay, or black screen occurrences. For signals within the same group, it offers a freezing seamless switching effect.

The device also supports Picture-in-Picture (PIP) and Picture-on-Picture (POP) modes, allowing users to insert a secondary video window (PIP) into the main background picture, or display two independent video sources side-by-side (POP). The size and location of these windows can be freely adjusted.

Another notable function is the Text Overlay mode, which enables users to add captions, company logos, or animations onto the current video picture. These captions can be created using office software like PowerPoint.

For output, the LVP603 provides VGA and DVI digital graphic signal outputs. The VGA output can be used for local monitoring, while the DVI outputs are typically connected to external LED transmission cards or boxes to drive the LED screen. The processor supports various output resolutions, including 1024x768, 1280x1024, 1600x1200, and 1920x1080, with different refresh rates.

The LVP603 also supports parallel operation, where multiple units can be connected to drive larger LED screens. In such configurations, each LVP603 unit captures a specific part of the overall input image to form a complete large picture.
