BriteView DVI Video Deinterlacer/Scaler
We first reviewed the Brite-View video scaler late last year and were pleasantly surprised at the performance of this low priced unit ($599). The deinterlacing and scaling were exceptionally good, and for consumers who have displays with poor video processing, the product offered an economical solution to achieving a high quality picture.
Unfortunately, some of the older displays with built-in deinterlacers have limitations, making an external video processor desirable. However, the cost of external processors prevented many from making such a purchase. Taiwan-based Zinwell Corporation recently introduced the new Brite-View DVI deinterlacer/scaler which appears to have all the great attribute of the previous model with the addition of a DVI output. The unit supports both RGB and YPbPr modes, yet resolutions are specific for the color space setting. The RGB mode supports 640x480 (60Hz), 800x600 (60Hz/75Hz), 1024x768 (60Hz/75Hz) and 1280x1024 (60Hz) modes, geared for VESA display compatibility typically with 4:3 screens. The YPrPb mode supports 480p, 720p and 1080i resolutions and is ideal for 16:9 displays. Priced at $599, the unit is marketed to entice videophiles on a budget while providing them with quality video processing.
The Brite-View DVI is built in the same sturdy housing as its predecessor with only a blue light on the front panel. Also behind the small window in the front lies the IR detector for the remote control. No front panel controls are available to the user, so the remote is essential for operating the unit. The unit defaults to the 480p mode when the color space switch is set to YPrPb and the 1024x768 (75Hz) mode when the switch is set on RGB. The remote appears to be unchanged from the previous design with dedicated buttons for Contrast, Brightness, Color, Tint and Sharpness. The Resolution button selects between the different scan rates depending on the position of the Color Space switch at the back of the unit. The Format button selects between 4:3 or 16:9 in the RGB mode only. The YPrPb mode assumes the video uses 16:9 content. The Language button selects English, German or French. Two buttons for increasing and decreasing the selected mode are also provided. Finally, three Input Source buttons select from the Composite, S-Video or Component inputs.
The rear panel of the new Brite-View DVI has the additional DVI interface not found in the earlier model. The same power switch and color space switch is located in the back. Input connectors are provided for composite, s-video and component video sources. Analog video is sent out via a high density 15-pin connector (VGA style). Digital video uses the standard Molex-style DVI-D connector. The power adapter included with the unit is a switching power supply capable of sourcing over one amp at 12 volts DC.
The Brite-View DVI uses the same highly integrated Trident DPTV -3D scan-conversion chip found in the previous model. We were quite impressed with the performance of this video processor. This powerful chip features 10-bit analog-to-digital converters with a full motion adaptive 3-D comb filter for Y/C separation for the composite input. In addition, the internal input multiplexer accommodates composite, s-video and component inputs. The chip uses four 16 Mbit (16-bit x 1MB) SDRAMs to handle motion-adaptive video processing algorithms. As a result of using this device, the circuit design is greatly simplified because video decoding and scan-conversion takes place on the same chip. Finally, the 10-bit digital-to-analog converters are also integrated on the same chip. The complexity of the design results in a substantial amount of power being dissipated from the 208-pin package and therefore requires a heat-sink mounted on the top for cooling. This insures long term reliability by minimizing thermal stress. However, all of this is hidden inside of the box.
Next we moved to our Optoma DLP projector with an XGA (1024x768) native resolution. We connected the EzPro 757 using the DVI connection. After all, this is the big improvement made to the Brite-View DVI processor. The image was projected onto our Stewart FireHawk reference filmscreen. Setting the unit to RGB mode and matching the DLP projector's native resolution resulted in a great picture with exceptional deinterlacing. Even though this projector is geared more for business presentation purposes, it worked well as a test projector when used with the Brite-View DVI, especially when watching high resolution DVD content.
The on-screen display shows the scan rate in the upper right corner of the video for a few seconds when the user changes the setting. However, this is not very useful if the display cannot synchronize to the video scan rate. There are no indicators on the front panel to let the user know what mode the processor is set to and this can leave the user guessing. Indicators on the front panel would be a value-added feature that would improve upon the current design.
