Comparison Trimax OzoneHD T2 Wi-Fi vs WeTek Play

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, t...his version 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.

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.

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.

The volume ofits 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 content on the device, you should definitely pay attention to models with a capacity of 32 GB or more.

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 for 2021 is H.265), 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.

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.
