Sea Mead Q10 four-generation evaluation, HDR quality enhancement technology in the end how?


Maybe you are no stranger to 4K or even experience its extremely clear picture quality, but with technological innovations, HDR now also appears, and it will become the next big thing in the television field. For now, HDR already has official definitions and official standards, and then it will also come to the mainstream crowd through video streaming services. Then, the new 4K Blu-ray movies also listed HDR as a standard technology. The combination of 4K and HDR means that the arrival of ultra-high-definition, ultra-high dynamic images is more enjoyable than the current 1080p Full HD standard and our viewing experience will be essentially different.


Want to appreciate the charm of HDR, in addition to video sources, the most important equipment or technical support. Haimeidi Q10 four-generation network set-top box, equipped with the latest Hass Hi3798C V200 chip, using 64-bit A53 processor, clocked up to 2.0GHz, integrated multi-core Mali-T720 GPU, support H.265 encoding 4K2K@60fps decoding, H.264 encoding 4K2K@60fps decoding, support for HDMI2.0 output, maximum resolution 4K2K@60fps, is the main scheme of the Haimeidi Q10 four generations to become a high-end smart box.
Then, what are the highlights of the four generations of Haimeidi's Q10 and the replacement of the "core"? Does HDR have much to expect?
First of all, let's first find out what HDR is. HDR, or high dynamic range, is centered on the fact that the higher the dynamic range is, the closer the picture quality is to the reality. The two most important criteria for measuring the quality of a television are contrast and color. The same two TV screens, one with better contrast and more accurate colors, and the other with only a relatively high resolution, believe that more people will favor the former and feel that the picture quality is better.


In general, an ordinary TV has a brightness of about 100 nits to 300 nits, and an HDR TV can theoretically reach a maximum of 5000 nits. Of course, HDR TV does not run bright eyes, it is only to widen the scope in order to better show light and shadow. The core idea of ​​HDR is to let the audience see more things, whether it is the shadow or the details of the highlights, you can see. The sun will not be as dazzling, the colors will be fuller and truer, and the gradient of the hue will be more delicate. In general, HDR TV will present more natural and realistic images.

The four-generation chip solution used by Haimedi Q10 is based on Android to build a system that meets advanced security requirements. The entire security scheme protects the use of high-quality Ultra HD content from all details. The overall protection mechanism includes loading from boot, boot, and Android kernels. , middleware running, app operation to interface UI operation.
Since there are four generations of Haimedi Q10 on the device, then the content of HDR will be worse. At present, Amazon's streaming service has some HDR resources, but the number is very limited. Fortunately, Netflix said it will launch HDR content by the end of 2015. As we all know, the higher the clarity, the higher the stream of video sources, the need for equipment in the decoding and storage capabilities of a high degree of cooperation and support. Maritime Q10 four generations also solve this problem perfectly, built-in hardware decoder HiVXETM2.0 video engine, using 2 times the decoding pipeline unit, high-definition dynamic picture smooth playback without pressure. In addition, equipped with 2GB DDR and 8GB flash memory also allows the system to run faster and smoother. With the extra brightness storage and transmission capabilities, 4K Blu-ray and video streaming can add extra HDR data (metadata) to the signal. It will tell HDR/WCG what the TV picture should look like. Those colors should be deeper, and what the specific brightness of highlights, reflections, stars, the sun and blasting should be. It can even adjust picture settings or automatically change to a specific picture mode.

For users who are observing the quality of their videos, the four generations of the Hermes Q10 are an excellent choice. It will allow you to experience clearer picture quality, richer colors and more realistic images. Enjoy the uniqueness of HDR lighting at home and bring a cinematic visual feast. This product is coming soon, so stay tuned.

Hybrid Inverter

A hybrid inverter is an inverter that combines the functions of an inverter and a charge controller. Its main function is to simultaneously process the direct current generated by solar panels and the electric energy of the battery energy storage system in a photovoltaic power generation system. It converts the direct current generated by the solar panels into alternating current for power and stores the excess power in the battery so that it can continue to supply power when needed.

Main effect:

Solar power generation: Hybrid inverters convert the direct current generated by solar panels into alternating current for home, commercial, or industrial electricity needs.

Battery energy storage: The hybrid inverter is equipped with a battery energy storage system that can store excess solar power. When the Solar Panel cannot generate enough electricity, the electricity stored in the battery can continue to supply electricity to achieve a continuous power supply.

Grid-connected function: Some hybrid inverters also have grid-connected functions, that is, the excess electric energy is integrated into the grid for use by other users. This allows them to interact with the grid, be self-sufficient, and export electricity to the grid.

Differences from other inverters:

Charging control function: The hybrid inverter combines the functions of an inverter and a charge controller, and can simultaneously process the DC power of the solar panel and the DC power of the battery energy storage system, realizing the hybrid application of solar power generation and battery energy storage.

Standalone operation: Unlike microinverters, hybrid inverters can operate independently and do not require an inverter for each solar panel, so it may be more economical and convenient when the system is larger.

Applicable scenarios: Hybrid inverters are widely used in home, commercial, and industrial photovoltaic power generation systems, especially in hybrid application scenarios that require photovoltaic power generation and battery energy storage.

In general, the main function of the hybrid inverter is to convert the direct current of the solar panel and the battery energy storage system into alternating current, so as to realize the hybrid application of photovoltaic power generation and battery energy storage. Compared with other inverters, it has higher flexibility and reliability in energy management and power supply stability.
