On the Bench
Sonyâ€™s BDP-S570 had excellent performance across the board on the Secrets Blu-ray Benchmark ranking it up there with some of the best performers weâ€™ve seen such as the OPPO BDP83 and the recently reviewed Cambridge Azur 650BD. Measurements were taken at 1080i from the component analog outputs using our Tektronix Oscilloscope. Core performance was excellent with the player gliding through our tests for both Y/C delay and pixel cropping. Everything was in perfect alignment on both the HDMI and component side and, a full HD image was displayed without any cropped pixels. The BDP-S570 was measured to have a white level of 101 IRE which is within our +/- 2 IRE tolerance range, and gets it a passing score for the test. While the player did pass a below black signal using the HDMI outputs, I was unable to make the player display below black using the component analog outputs. As you can see from the graph, the frequency response of the BDP-S570 was very even with a minor dip into the higher frequencies. This translates to excellent picture quality with very slight softness in finer detail when viewed using component analog video cables. The BDP-S570 did not exhibit the chroma upsampling error on any of our tests.
Standard DVD Performance
The BDP-S570 was an outstanding performer in our standard deinterlacing tests with the player passing all but one of our tests with flying colors. While the player passed all of the basic film cadences tests, it, like many other recent Blu-ray players we have reviewed, had some hiccups when handling material that is alternating between standard film-style flags and video-style flags and artifacting was witnessed. The BDP-S570 had excellent results with our high detail tests using both the Super Speedway and Gladiator clips. The player locked on to the patterns quickly and displayed an image with excellent detail. We can keep our fingers crossed for Sony to provide a firmware update for the mixed flag issue it exhibited.
On video based material the BDP-S570 also had solid performance. The player is motion adaptive and was able to pass all of our 2:2 cadence tests. Recovery time on the BDP-S570 from switching between film and video modes could stand to be quicker but was just fast enough to get a passing score on our test.
The BDP-S570 had very good performance in the HD section of the benchmark. For starters, the BDP-S570 is able to do a proper 1080i/p conversion in both 2:2 and 3:2 cadences which means that it can play this material, which is often seen on documentary and concert footage, with high detail and free from artifacts. The BDP-S570 is motion adaptive and passed our edge adaptive diagonal filtering tests showing that it could reconstruct an image and display edges that were free from jaggies. The BDP-S570 has a basic set of noise reduction features including Frame Noise Reduction, Block Noise Reduction, and Mosquito Noise reduction. I found that the FNR feature worked well and had a significant impact on reducing random noise but the BNR and MNR features didnâ€™t perform as well. Furthermore, with this player having internet enabled features, noise reduction features which address upscaled compression artifacts become more important. Since, the BDP-S570 wasnâ€™t able to adequately reduce the noise inherent with these types of images it only received a borderline score on our noise reduction tests for only being able to successfully deal with random noise. Finally, the BDP-S570 was able to pass both the banding test as well as produce a full 1920x1080 image without cropping any pixels.
The BDP-S570 had very good performance on the usability section of the benchmark. The player operated briskly and was responsive from the remote and had an excellent layer change clocked in at just over a half a second.
