Bluetooth

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.

Wi-Fi

Wi-Fi is a technology used for wireless connection to computer networks and for direct connection between devices. In media players, tuners and video capture devices, it can be used both to access the Internet or "local area" through a wireless router, and to communicate with a smartphone, tablet, etc. The AirPlay, Chromecast and Miracast functions are also based on this technology. The specific set of Wi-Fi features should be clarified separately; here we note that in this paragraph the specific supported version of such a connection can also be specified. Here are the main current options:
  • Wi-Fi 5(802.11ac). One of the newest (for 2020) standards. Uses the 5 GHz band (less crowded than used in earlier 2.4 GHz versions) for improved reliability and lower latency; and speeds can reach 6.77 Gbps with multiple antennas and 1.69 Gbps with a single antenna.
  • Wi-Fi 4 (802.11n). The predecessor of the above Wi-Fi 5, the first standard in which the 5 GHz band was introduced — here it is used along with the traditional 2.4 GHz and is not supported by some devices with Wi-Fi 4. Data transfer rate — up to 600 Mbps.
Note that, in addition to the directly claimed Wi-Fi standard, the media centre, digital receivers and video capture devices usually provide support for earlier versions — for maximum compatibility with different devices.

Optical output

A variation of the SP/DIF audio interface that uses a TOSLINK fibre optic cable. Like the coaxial connector, the optical output uses a digital data transfer format and can work with multi-channel audio. At the same time, optical fibre requires rather delicate handling, but it is absolutely insensitive to electrical interference.

CPU

The model of the CPU installed in the media player.

This information is mainly of reference value: the processor is selected in such a way as to provide certain practical characteristics (maximum resolution, support for certain standards, embedded applications, etc.). So when choosing, you should focus primarily on these specifications. However, if you wish, knowing the processor model, you can find detailed data on it and evaluate the capabilities of the media centre to work with resource-consuming applications. This can be useful, in particular, if you choose an Android model (see above) and plan to use additional software intensively — the set of applications for this OS is very extensive, and some of them are quite demanding on system resources.

Also note that CPU data is often specified for advertising purposes — to emphasize that the device has a fairly advanced chip from a well-known brand. Among the most common brands of such processors are Allwinner, Amlogic, Rockchip, Realtek.

CPU cores

The core is the part of the processor that executes a single thread of instructions. Accordingly, the presence of multiple cores allows to work with multiple threads simultaneously, which has a positive effect on performance. Theoretically, more cores (4 cores or even 6 cores or more) can increase the efficiency of the processor. However, in fact, CPU performance depends on so many additional factors that the number of cores is purely a reference parameter. So, a high-end dual-core processor may well be more performant than an inexpensive quad-core one.

RAM

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.

Video decoders

Codec — from the phrase "Encoder-DECoder" — in this case is the format used for encoding digital video during storage/transmission and decoding during playback (without encoding, video data would take up an unjustifiably large amount of space). Do not confuse this parameter with the format of video files: different files of the same format can be encoded with different codecs, and if the corresponding codec is not supported by the player, video playback will be impossible, even if the file format itself corresponds to the capabilities of the device. And in models with online TV support (see "Features") this nuance also determines compatibility with a specific broadcast: the general format of the broadcast is indicated by the codec used for this.

In general, modern devices usually have quite extensive sets of codecs (one of the most advanced is H.265, AV1 codecis also popular), and there are usually no problems with video playback; in extreme cases, you can use special programs for transcoding files. As for specific codecs, detailed data on them can be found in special sources, but with standard use of media players, such details are not needed.

Audio decoders

The set of audio codecs supported by the device

Codec — from the phrase "Encoder-DEcoder" — in this case, the format used for encoding and compressing sound in digital form during storage/transmission and decoding — during playback (digital sound is basically impossible without encoding, and compression allows to reduce the amount of data). Information about supported codecs is relevant primarily for assessing whether the player will be able to work with sound in a particular video file. The fact is that even in video files of the same format (see below), sound can be compressed by different codecs; and if the player supports the file format, but does not support the codec, sound playback will become impossible.

Theoretically, these rules are also relevant for audio files and online broadcasts (all formats — TV, video, audio). However, in fact, when working with such content, you can ignore codec data. So, for each audio file format, usually, its own standard codec is used, and file type support automatically means codec support. Broadcasts usually use generally accepted audio decoders like MPEG-1 or MPEG-2, which are practically guaranteed to be supported by any modern player designed for such broadcasts.

As for specific codecs, detailed information on them can be found in special sources, however, with the standard use of devices, such details are usually not needed.
