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.
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.
Built-in memory
The volume of
its own storage installed in the media player.
In this case, storage means permanent memory available to the user — the storage that you can fill with movies, music, applications, etc. The larger the volume of such storage, the more convenient it is for the user; on the other hand, this parameter significantly affects the cost of the entire device. In addition, it should noted that external media are also quite suitable for films and other multimedia content — flash drives, portable HDDs, drives installed in a slot (see below), optical discs, etc. So specifically look for a model with a capacious storage makes sense in two main cases. The first is if you want to keep an extensive collection of content in the media player, so as not to bother once again with connecting flash drives, loading disks, etc. it is best to put it in the built-in memory, and often this is the only possible option).
As for specific volumes, the capacity
up to 4 GB is considered very limited nowadays; such a storage is not enough even for a movie in HD 720p, its purpose is mainly to store a small set of applications.
8 GB and
16 GB are also relatively small, but this already allows you to work with a fairly extensive set of software and store individual movies in HD resolutions. And if you initially intend to store a large amount of c
...ontent on the device, you should definitely pay attention to models with a capacity of 32 GB or more.
