Huidu HDP902 Video Processor
Huidu HDP902 Video Processor Overview
The HDP902 is a powerful 3-channel multi-graphic multi-input splicing processor that can be used in a wide range of small and medium splicing applications, as well as for image switching and image scaling. The splicing processor has 3 channel splicing, 1 channel monitoring, and the widest can be spliced to 11520 points. It can also achieve equal-splicing, unequal splicing, display of different resolutions, three-screen splicing and other functions.。
Multi-channel video input – HDP902 can access up to 13 channels of video input, including 2 DVI, 4 HDMI, 2 VGA, 4 CVBS, 1 3G-SDI/SDI-LOOP (optional); Both receive standard resolution or high resolution video signals, DVI and VGA can receive up to 1920 × 1200 @ 60Hz resolution input.
Practical video output interface—The processor has 8 channels of video output, 7 channels of DVI, and 1 channel of SDI-LOOP.
Seamless switching of any channel—The HDP902 video processor can also seamlessly switch between any channel, and the switching time can be adjusted from 0 to 1.5 seconds. Use the fade switch effect to switch the input channel smoothly to switch to the second and third screens. With fast switching, you can instantly switch the video output when switching input channels.
Rich output resolution – HDP902 has designed a variety of practical output resolutions for users, 795W pixel custom resolution, the widest up to 11520 points, the highest up to 5760 points, for a variety of dot matrix display. Up to 20 output resolutions are available for user selection and can be adjusted to point-to-point output.
Support pre-switching technology—pre-switching technology is to predict in advance whether the switched input channel has a signal when switching the input signal. This function reduces the possibility of direct switching due to disconnection or no signal input, which increases the success rate of the show.
Support picture-in-picture-picture-in-picture technology, superimposing another picture with the same or different input while the original image is unchanged. HDP902’s picture-in-picture function not only can adjust the size, position, border, etc. of the overlay layer arbitrarily, but also multi-window seamless switching. When 1 screen is cut, the fade-in and fade-out effects can be realized, and 3 draws and draws 3 shots. Window) can also achieve fade effect.
Support pre-switching technology—pre-switching technology is to predict in advance whether the switched input channel has a signal when switching the input signal. This function reduces the possibility of direct switching due to disconnection or no signal input, which increases the success rate of the show.
The engineering lock can be set—the user can set the number of uses of the machine. When the number of uses is reached, the device can stop working.
Support for screen freeze – During playback, you may need to freeze the current screen to achieve a “pause” screen. When the screen freezes, the operator can also change the current input selection or change the line, etc., to avoid background effects affecting the performance.
Partial and full-screen fast switching—HDP902 has simple and practical part of the screen operation and full-screen operation. Any input channel can independently set different interception effects, and each channel can still achieve seamless switching. The user can arbitrarily set the size and position of the screenshot of the current channel, while the interception methods of other channels are unchanged. When switching, partial screen or full screen function is implemented between each channel.
Preset call function—The HDP902 uses 8 sets of user presets, and each set of user presets can store all user setting parameters.
The unequal splicing and splicing splicing-splicing function is an important part of the HDP902. It can realize halving and unequal splicing, which greatly meets the various needs of users in splicing. Frame synchronization, 0 delay, no tailing and other techniques are implemented in multiple processors to make the performance perfect. The unequal splicing and the screen part output are in the same setting mode, and the user can read the operation instructions of the following chapters in detail.
- bit image lossless scaling technology—HDP902 uses a dual-core image processing engine. A single core can handle 30-bit image scaling technology. The width can be output from 64 to 3840. At the same time, it can achieve 10 times image magnification output, that is, the widest reach. 38400.
That is, the ready-to-use technology—that is, the ready-to-use technology solves the user’s cumbersome setup and manual storage process, that is, the user does not need to perform manual save operation after adjusting or adjusting parameters, and the HDP902 automatically stores the user parameters in the EEPROM even if the power is turned off. After powering on, the parameters before power off remain in the device.
Application scenario
Simultaneously display video playback devices such as computers/TVs/cameras.
