The Panasonic DMP-BDT110 3D/Network Blu-ray Player combines an innovative, stylish design, with good performance. The DMP-BDT110 provides 2D and 3D playback of Blu-ray Discs, 1080p upscaling of standard DVDs via it HDMI ver1.4a output. The DMP-BTT110 also provides the ability to stream audio/video content from the internet, such as Netflix, Vudu, and Pandora.

In order to test the video upscaling performance of the Panasonic DMP-BDT110 Blu-ray Disc Player, I used the standardized HQV DVD Benchmark Test Disc from Silicon Optix (IDT). The disc has a series of test patterns and images that determine how well a video processor in a Blu-ray Disc/DVD player, TV, or Home Theater Receiver can display a good quality image when faced 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 ​n Panasonic DMP-BDT110 Blu-ray Player using the HDMI output connected alternately to a Panasonic TC-P50GT30 Plasma TV (on review loan) and Westinghouse LVM-37w3 LCD Monitor, both with 1080p native resolution. The Panasonic DMP-BDT110 was set for 1080p output so that the test results reflected the video processing performance of the DMP-BDT110 .

The test results are shown as measured by the Silicon Optix HQV DVD Benchmark Disc.

Screenshots in this gallery were obtained using a Sony DSC-R1 Digital Still Camera. Photos were taken at a 10-Megapixel resolution and resized for posting in this gallery.

After going through this Step-by-Step look at some sample tests, also check out my supplementary Photo Profile and Review of the Panasonic DMP-BDT110 Blu-ray Player.

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 bar is very smooth as it passes through yellow and enters the green zone. The Panasonic DMP-BDT110 passes this portion of the test.

Pictured on this page is a second look at the rotating line test. As outlined on the previous page, 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 shows just a very slight roughness along the edges but is not jagged as it moves from the green zone and into the yellow zone. The Panasonic DMP-BDT110 passes this portion of the test.

Pictured on this page is an additional, more close-up, look at the rotating line test. As you can see, as shown in this photo, the line does have slightly rough edges and a slight wrinkling along the edges and curling on end. However, this is still a good result and means that the Panasonic DMP-BDT110 passes this test.

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 rough along the edges (click for larger view). This means that the Panasonic DMP-BDT110 is considered to be passing this deinterlacing test.

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, but two or three straight lines would show better results.

As you can see, none of the lines are jagged and the bottom line is only slight roughness along the edges, but the bottom line is not jagged or wavy. This is a good result and means that the Panasonic DMP-BDT110 passes this deinterlacing test.

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 Panasonic DMP-BDT110 passes this test.

By proceeding to the following photo in this gallery you will see the results with regards to the differing position of the flag as it waves.

Here is a third, and final, look at the flag waving test. As mentioned previous page, if there are jagged edges showing, the 480i/480p conversion and upscaling is considered below average. As you can see here, the stripes of the flag are mostly smooth along the edges of the flag and within the stripes of the flag. Once again, the Panasonic DMP-BDT110 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 Panasonic DMP-BDT110 is very good so far.

Pictured on this page is one of the tests that shows how good the video processor of the Panasonic DMP-BDT110 is at detecting 3:2 source material. In other words, the video processor has to be able to detect 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 Panasonic DMP-BDT110 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 Panasonic DMP-BDT110 with regards to ​the 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 Disc 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.

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 Panasonic DMP-BDT110 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 Panasonic DMP-BDT110 with regards to​ the accurate processing of film or video-based content containing detailed backgrounds and fast moving foreground objects.

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 Panasonic DMP-BDT110 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 (any blurriness is due to the camera's shutter) and shows that the Panasonic DMP-BDT110 detects and shows a very stable scrolling title image.

Panasonic DMP-BDT110 - High Definition Resolution Loss Test

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​ the 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.

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 DMP-BDT110 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.

However, as seen in this close-up photo of the rotating bar, which appeared smooth in the previous photo, still looks fairly smooth in this close-up. This is a good result as it shows that the DMP-BDT110 does well with both 1080i to 1080p still image conversion and 1080i to 1080p conversion of moving images. NOTE: Blurriness and ghosting in the photo is caused by the camera shutter.

Final Take

In a further testing not shown in this profile, the Panasonic DMP-BDT110 did an excellent job rendering the 3:2 Pulldown film, 2:2 and 2:2:2:4 frame cadences, but did display some instability on some of the more unusual cadences, such as 2:3:3:2, 3:2:3:2:2, 5:5, 6:4, and 8:7. On the other hand, the DMP-BDT110 did an excellent job of handling video-generated titles (30 fps) superimposed over film-based material (24 fps) without any signs of jaggedness or other noticeable artifacts. For a detailed explanation on the above cadence tests, and why they are conducted, refer to the HQV Website.

However, the DMP-BDT110 did exhibit background video noise and mosquito noise artifacts with the test material.

What all the above technical explanations mean is that the DMP-BDT110 's built-in video processor and scaler, although not perfect, does deliver a very good image on the screen, in real world conditions, with most standard definition and high definition material.

As a final point, there are idiosyncrasies that can come up with specific disc releases that may affect playback or menu navigation. It is important to check for firmware updates, which can be accessed using the player's Ethernet or WiFi connection.
