Samsung & Amazon Introduce HDR10+ Standard with Dynamic Metadata & Tone Mapping

Most recent 4K Ultra HD televisions support high dynamic range (HDR) through standards such as HDR10, Dolby Vision, or Hybrid Log-Gamma (HLG). Samsung and Amazon have jointly introduced an update to HDR10 with HDR10+ that adds dynamic tone mapping & metadata. The companies describe the issues for HDR10′ static metadata as follows: The current HDR10 standard utilizes static metadata that does not change during playback despite scene specific brightness levels. As a result, image quality may not be optimal in some scenes. For example, when a movie’s overall color scheme is very bright but has a few scenes filmed in relatively dim lighting, those scenes will appear significantly darker than what was originally envisioned by the director. HDR10+ will be able to adjust metadata for each scene, and even for each frame, hence solving the issue of darker scenes. If you already own a Samsung TV with HDR10, it’s not […]

Karl’s Home Automation Project – Part 4: MQTT Bridge Updated to Use YS-IRTM IR Receiver & Transmitter with NodeMCU

In a previous article, I wrote about an MQTT bridge by 1technophile. I added a DHT temperature and humidity sensor as well as a light sensor. Previously it included a software decoder to decode the IR signal. I never did test the IR transmitter on the gateway, as I didn’t have the parts. But thanks to IC Station, who sent me over a small YS-IRTM hardware based decoder and NodeMCU that I am writing about today. I have replaced the software based version with the YS-IRTM module in the latest update. I found this project challenging. I admit I am a little weak in my programming skills. It was difficult to find documentation but I found a forum talking about this device and basics of how it works. When an IR code is recognized it sends 3 hex codes via serial connection on the transmit pin. To transmit, it expects […]

The Cheapest MP3 Players Are now Selling for Under $1 including Shipping…

Most of us now listen to music on the go using our phones, but once upon a not-so-distant time, portable MP3 players were a popular way to listen music. They have not completely disappeared, and Brad Linder of Liliputing needed some for one of his projects, so he bought four inexpensive MP3 players on GearBest with prices ranging from $1.51 to $3.75 to check them out. It turns out the one with the best audio quality and sturdiness was Simplicity Fashion Pocket MP3 Player going for $1.51 shipped. So let’s see what we get for that price: Audio – 3.5mm audio jack Storage – micro SD slot up to 16GB (no internal storage) USB – mini USB port for charging, and connect to PC which detects the MP3 player as an SD card reader (but it’s rather slow) Misc – Power, volume, next, previous, and play/pause buttons; metal clip; power […]
