— Proprietary system. The operating system of the device is represented by the proprietary software shell of the manufacturer. Usually, such operating systems have an attractive and convenient menu. A proprietary operating system is developed directly by the manufacturer for the hardware resources of a particular model or a whole line, but has limited capabilities.

— Android (AOSP). This type of operating system is a modification of the popular Android OS, mainly notable for being open source. It is a versatile operating system that gives the user much more freedom to create changes and customizations within the system itself. At the same time, the installation and stability of certain applications on this platform are not guaranteed, and the overall system management was not specially “tailored” for large screens, which may cause some inconvenience. First of all, such solutions will interest users who understand the features of the Android OS, like to customize and control everything for themselves, and have time for this.

— Android TV. Devices of this type have full-fledged Android TV software, specially adapted to work on large screens. In accordance with the name, it is a type of Android OS, specially designed for such equipment. In addition to the common features of all Androids (such as the ability to install additional applications, including...even games), it has a number of special features: an optimized interface, integration with smartphones (including the ability to use them as a remote control), voice search, etc. Thanks to this, TVs with this feature are significantly superior in functionality to models with a “regular” Smart TV. Of course, a dedicated processor, graphics subsystem and memory are provided for the operation of a multifunctional OS, and the presence of such hardware resources is reflected in the overall cost.

— Google TV. Rebranding of the Android TV platform for TVs and smart consoles, or rather, a new shell on top of the operating system under the sign of the “green droid”, introduced since 2021. Among the innovations, it has a redesigned user interface, an improved knowledge base that more efficiently distributes content by genre and collects search information from the entire list of installed applications and subscriptions. The voice assistant now understands the needs of the audience better and provides a detailed list of what was found. A separate tab in the interface contains live broadcasts of current events, whether it be sports events or a rocket launch to Mars. Among other things, the aspects that involve the use of TV as a command post for managing a single ecosystem of a “smart” home have been improved in the system.

Bluetooth is a technology used to connect various devices wirelessly directly. In media centers and TV receivers, it can be used to broadcast sound to wireless headphones and acoustics, to work with wireless mice and keyboards, to use a smartphone / tablet as a remote control, etc.; specific functionality should be specified separately. Also note that the supported version of Bluetooth can be specified here. The newest and most advanced is Bluetooth 5.0, but here is a more detailed description of the different versions:

• Bluetooth v4.0. The version in which the "Bluetooth Low Energy" (LE) format was first introduced — in addition to regular Bluetooth (version 2.1 functionality) and the high-speed HE standard for transferring large amounts of information (introduced in version 3.0). Bluetooth LE allows you to significantly reduce power consumption when transmitting small data packets, such as request-responses about connection activity in idle mode. For the media centers and TV receivers themselves, this is not particularly important, but for portable equipment (especially miniature ones, where battery capacity is very limited), such functionality will be useful.
• Bluetooth v 4.1. Development and improvement of Bluetooth 4.0. One of the key improvements was the optimization of collaboration with 4G LTE communication modules so that Bluetooth and LTE do not interfere with each other. In addition, this ve...rsion has the ability to simultaneously use a Bluetooth device in several roles — for example, to remotely control an external device while simultaneously streaming music to headphones.
• Bluetooth v4.2. Further, after 4.1, the development of the Bluetooth standard. It did not introduce fundamental updates, but received a number of improvements regarding reliability and noise immunity, as well as improved compatibility with the Internet of Things.
• Bluetooth v5.0. Version introduced in 2016. One of the most notable updates was the introduction of two new modes of operation for Bluetooth LE — with an increase in speed by reducing the range and with an increase in range by reducing the speed. In addition, a number of improvements have been introduced regarding simultaneous work with numerous connected devices, as well as work with the components of the Internet of Things.

The technology of broadcasting audio and video signals through a Wi-Fi connection. Widely used in Apple electronics, the media centre with AirPlay will make it easy to duplicate a “picture” on a TV, for example, from an iPhone or iPad. The main disadvantage of this technology compared to similar Miracast is the need for a local network with a wireless router.

LAN — connector for wired connection to the Internet and/or local area network using an Ethernet cable. A wired connection is not as convenient as Wi-Fi (see "Multimedia"), but it is considered more reliable and provides faster data transfer speeds. And the speed indicators depend on the device and can be 100 Mbps and 1 Gbps.

— AV output. Analogue output for video and audio transferring. Previously, due to the large size of the equipment, it consisted of 3 RCA jacks and was connected to the TV accordingly. Now the devices have become more compact and don't have free space on the case. Therefore, the AV output is a single headphone jack, to which a tee cable is already connected (check availability in the package). Since all components of the video signal are on the same cable, the picture quality and immunity to interference are low.

In this case, the term coaxial refers to a type of SP/DIF interface that uses an electrical cable with an RCA connector. This interface provides sound transmission, including multichannel, in digital format; at the same time, the electrical cable is more susceptible to interference than the optical one, but is not as fragile.

The clock speed of the CPU installed in the media centre.

On the technical side, the higher this indicator, the faster the processor works and the higher, accordingly, the overall system performance. At the same time, the CPU performance depends, in addition to the frequency itself, on a number of factors — architecture, number of cores, special design features, etc.; and the actual speed of the entire system is affected by performance of components other than the processor. In addition, manufacturers usually select processors in such a way that their computing power is guaranteed to be enough for all the features claimed for a media centre. Therefore, in this case, the CPU frequency is more of a reference parameter (and partly an advertising indicator that demonstrates the advanced specifications of the device), rather than practically significant for buyer.

The amount of RAM installed in the media player.

In general, this volume is selected by the manufacturer in such a way that the device can normally cope with the tasks that are claimed for it. On the other hand, all else being equal, more RAM usually means faster performance. This parameter is especially important if the media player runs under the Android OS (see above): such firmware allows the installation of additional applications that may have rather high requirements for RAM.

As for specific values, by modern standards, a device with more than 2 GB of RAM is considered a fast media player.

The ability to play video in ultraHD 4K on the device. This format covers several resolutions, all of which have a horizontal size of approximately 4000 pixels. However, the most popular is the frame size of 3840x2160 — in particular, this is the standard value for 4K TV screens; therefore, most UltraHD content is also released in this resolution.

A 3840x2160 frame contains 4 times more pixels than the popular Full HD standard, resulting in an even sharper and more detailed image. Of course, you will need a TV (or other screen) of the appropriate resolution to fully enjoy the experience; but such screens nowadays are becoming more common and affordable.
