The Eiki HQView420 HQV Scaler-Switcher with Warp and Edge Blend adds free form warp capability for certain non-flat screens in a multi projector installation. Warp maps created with the PC tool “Warp Generator” can be uploaded into HQView420 and processed accordingly. Harnessing the power of the Reon™ video processor from IDT, running state of the art HQV algorithms with expertly designed hardware and firmware from Eiki, HQView420 is a highly flexible image scaler which provides stunning image quality for professional, broadcast and corporate AV users.

The HQView420 includes 4-sided soft edge blend for seamless blending of multiple projectors and includes flexible geometry correction functions able to correct image shape and projector misalignment by dragging and dropping each image corner, or by pin, barrel, rotation or by keystone and rotation.

 

Full warp mapping is supported by HQView420. A flexible and intuitive PC application is included for easy warp map creation, or third-party generated warp maps can also be processed form automatic image alignment systems making the HQView420 ideal for dual overlaid projector alignment in 3D projection systems.

The HQView420 is a very flexible image scaler developed specifically for driving large screen displays and multiple screen applications from video or graphics sources. The HQView420 features state of the art digital image processor which provides market leading HD& SD per-pixel multiple Iow-angle motion-adaptive de-interlacing and automatic film pull-down correction for 3:2 and 2:2, significantly outperforming the capabilities of benchmark competitor products.

The HQView420 also features excellent image processing algorithms for the very best scaling, film and video noise reduction and MPEG artefact reduction.

The HQView420 uses a very flexible high performance video input front end including true component video support in analog YPbPr and RGBS formats and HDSDI/SDI digital formats as well as composite (CVBS) and YC/S-Video inputs. A very high performance video decoder is utilised with 4x oversampling and 3D Y/C separation for outstanding video image clarity. HDMI and DVI video with HDCP encryption is also supported, as are computer graphics inputs in SVGA analogue and HDMI/DVI digital formats.

The output format can be set to I/O Lock mode where it locks the output frame rate to the input frame rate dynamically without frame rate conversion so as to reduce system latency, or it can be set to a fixed output frame rate for driving basic screens which are not 50Hz-compatible. A Low latency mode with non-motion adaptive reduced processing is available to further reduce latency.

Outputs are available in VGA analog and DVI digital formats which are useable simultaneously so that one output can drive the screen while the other runs a local monitor. Note that if an HDCP encrypted signal is connected to the HDMI or DVI input, the DVI output signal will be similarly HDCP encrypted and the VGA analog output will be disabled.

The HQView420 can be operated with different firmware. At time of issuing this document three firmware options are available. Each firmware provides different feature sets controlled through the OSD. Thus, the OSD menu systems of the firmware options may deviate from each other. Special emphasize is given in the discussion of the OSD menu system in the corresponding chapters. The System control is via an OSD controlled by keys on the front panel or through the inbuilt TCP/IP web server.
