HQV Benchmark DVD Video Quality Evaluation Test Disc - Test List
In order to test the video upscaling performance of the OPPO Digital BDP-93, I used the standardized HQV DVD Benchmark Test Disc from Silicon Optix (IDT). The test disc has a series of test patterns and images that test how well a video processor in a Blu-ray Disc/DVD player, TV, or Home Theater Receiver can display a good quality image when face with a low resolution or poor quality source.
In this Step-by-Step gallery, the results of several of the tests listed in the list above are shown.
The following tests were conducted with an OPPO BDP-93 Blu-ray Disc Player using both HDMI outputs connected alternately to both a Sharp XV-17000 3D 1080p DLP video Projector (on review loan from Sharp) and a Westinghouse Digital LVM-37w3 1080p LCD Monitor. The OPPO Digital BDP-93 was set for 1080p output so that the test results reflected the video processing performance of the BDP-93. All tests were conducted using the BDP-93's factory default settings.
The test results shown in this gallery are taken from the BDP-93's HDMI 1 output, which utilizes the Marvell Kyoto-G2 Qdeo 88DE2750 processing chip, as measured by the Silicon Optix HQV DVD Benchmark Disc.
Screen shots in this gallery were obtained using a Sony DSC-R1 Digital Still Camera. Photos were taken at 10-Megapixel resolution and resized for posting in this gallery.

OPPO Digital BDP-93 - Deinterlacing/Upscaling Tests - Jaggies 1-1
Pictured on this page is one of several tests illustrated in this gallery. In this test a diagonal line moves in a 360 degree motion. In order to pass this test, the rotating bar needs to be straight, or show minimal wrinkling or jaggedness, as it passes red, yellow, and green zones of the circle. As you can see, as shown in this photo, the rotating line is very smooth as it passes through the yellow zone and enters the green zone.
The OPPO BDP-93 passes this portion of the test.

OPPO Digital BDP-93 - Deinterlacing/Upscaling Tests - Jaggies 2-1
Here is another test that measures deinterlacing capability (480i/480p conversion). This test consists of three lines moving and down in rapid motion. In order to pass this test, at least one of the lines needs to be straight. If two lines are straight that would be considered better, and if three lines were straight, the results would be considered excellent.
As you can see, the top two lines are not jagged or wrinkled, and the bottom line is just very slightly wrinkled along the edges.
This means that the OPPO BDP-93 is considered to be passing this deinterlacing test.

OPPO Digital BDP-93 - Deinterlacing/Upscaling Tests - Jaggies 2CU
Here is a second, more close-up, look at the three line test that demonstrates deinterlacing capability (480i/480p conversion). As outlined on the previous page, in order to pass this test at least one of the lines needs to be straight. If two lines are straight that would be considered better, and if three lines were straight, the results would be considered excellent.
As you can see, none of the lines are not jagged and the bottom line is only slightly wrinkled at the ends.
This means that the OPPO BDP-93 is considered to be passing this deinterlacing test.

OPPO Digital BDP-93 - Deinterlacing and Upscaling Tests - Flag Test 1
Probably the most demanding deinterlacing test is how a video processor can handle a waving American Flag. If the flag is jagged, the 480i/480p conversion and upscaling is considered below average. As you can see here (even when you click for the larger view), the stripes of the flag are very smooth along the edges of the flag and within the stripes of the flag. The OPPO BDP-93 passes this test.
By proceeding to following photo in this gallery you will see the results with regards to the differing position of the flag as it waves.

OPPO Digital BDP-93 - Deinterlacing and Upscaling Tests - Flag Test 3
Here is a third look at the flag test. If the flag is jagged, the 480i/480p conversion and upscaling is considered below average. As you can see here (even when you click for the larger view), the stripes of the flag are very smooth along the edges of the flag and within the stripes of the flag. The OPPO BDP-93 passes this test.
Combining the three frame results of the Flag Waving Test, it is evident that the 480i/480p conversion and 1080p upscaling ability of the OPPO BDP-93 is excellent so far.

OPPO Digital BDP-93 - Deinterlacing and Upscaling Tests - Race Car 2
Pictured on this page is one of the tests that shows how good the video processor of the OPPO BDP-93 is at detecting 3:2 source material. In other words, the video processor has to be able to dectect whether the source material is film based (24 frames per second) or video based (30 frames a second) and display the source material correctly on the screen, so as to avoid artifacts.
In the case of the race car and grandstand shown in this photo, if the video processing this area is poor the grandstand would display a moire pattern on the seats.
However, if the OPPO BDP-93 has good video processing in this area, the Moire Pattern will not be visible or only visible during the first five frames of the cut.
As shown in this photo, the moire pattern is not visible as the image pans and the race car goes by. This indicates good performance of the OPPO BDP-93 with regards to accurate processing of film or video-based content containing detailed backgrounds and fast moving foreground objects.
For another sample of how this image should look, check out an example of this same test as performed by the OPPO Digital BDP-83 Blu-ray Player from a previous review used for comparison.
For a sample of how this test should not look, check out an example of this same deinterlacing/upscaling test as performed by the Pioneer BFDP-95FD Blu-ray Disc Player, from a past product review.

OPPO Digital BDP-93 - Deinterlacing and Upscaling Tests - Titles
Here is a second photo of the "Race Car Test". As outlined on the previous page, if the video processor is poor the grandstand would display a moire pattern on the seats. However, if the upscaling section of the OPPO BDP-93 has good video processing, the Moire Pattern will not be visible or only visible during the first five frames of the cut.
As shown in this photo, the moire pattern is not visible as the image pans and the race car goes by.
This indicates very good performance of the OPPO BDP-93 with regards to accurate processing of film or video-based content containing detailed backgrounds and fast moving foreground objects.

OPPO Digital BDP-93 - High Definition Resolution Loss Test
Even though a video processor may be able detect the difference between video and film-based sources, such as shown in the previous photo, can it detect both of them at the same time? The reason this is important is that often, video titles (moving at 30 frames per second) are laid over film (which is moving at 24 frames per second). This can cause problems as the combination of both these elements can result in artifacts that make the titles look jagged or broken.
However, in this case, if the OPPO BDP-93 can detect the differences between the titles and the rest of the image, the titles should appear smooth.
As you can see in the real world example, the letters are smooth (the blurriness is due to the camera's shutter) and shows that the OPPO BDP-93 detects and shows a very stable scrolling title image.
In addition to the tests shown in this gallery, what is not shown are tests that determine how well the BDP-93 detects and processes variations in film cadences. In this area, the tests revealed that the BDP-93 showed good detection and process of a wide variety of cadences, including the most important 3:2 film cadence.
On the other hand, testing also revealed that the BDP-93 did not do as well in eliminating or minimizing video noise on source material where excessive video noise is present.
Proceed to the next, and last, test...
OPPO Digital BDP-93 - High Definition Resolution Loss Test Bar CU
In this test, the image has been recorded in 1080i, which the Blu-ray Disc player needs to reprocess as 1080p. The problem faced is the ability of the processor to distinguish between the still and moving parts of the image. If the processor does its job properly, the moving bar will be smooth and all of lines in the still part of the image will be visible at all times.
However, to throw a "wrench" into the test, the squares on each corner contain white lines on odd frames and black lines on even frames.
If the blocks continuously show still lines the processor is doing a complete job at reproducing all of the resolution of the original image. However, if the square blocks are seen to vibrate or strobe alternately in black (see example) and white (see example), then the video processor is not processing the full resolution of the entire image.
As you can see in this frame, the squares in the corners are displaying still lines. This means that these squares are being displayed properly as they are not showing a solid white or black square, but a square filled with alternating lines. In addition, the rotating bar appears smooth.
The results indicate that the BDP-93 does a very good job of resolving 1080i to 1080p.
Proceed to the last photo of the results...
Here is a close-up look at the rotating line in the test as discussed in the previous page. The image has been recorded in 1080i, which the Blu-ray Disc player needs to reprocess as 1080p. The problem faced is the ability of the processor to distinguish between the still and moving parts of the image. If the processor does its job properly, the moving bar will be smooth.
As you can see in this close-up photo of the rotating bar, it is smooth (blurriness caused by camera shutter).
The lack of jaggedness in the rotating line indicates that the BDP-93 does well with 1080i to 1080p still image conversion, and also 1080i images to 1080p when objects are in motion.
Final Take:
The test results shown in this gallery reveal that the OPPO Digital BDP-93 does excellent with progressive scan (3:2 pulldown), jaggie elimination (both rotating line and flag waving tests), detail, and 1080i to 1080p conversion.
In additional tests not shown in the gallery, the OPPO Digital BDP-93 also did an excellent job with motion adaptive processing and film and video cadence detection, but did not suppress background video noise as well as its predecessor, the BDP-83. On the other hand the BDP-93 did a little better at displaying a little more detail in upscaled images than the BDP-83.
