Comparison World Vision T624D3 vs Romsat T8008HD

A classic USB port for connecting flash drives, receivers, keyboards, and other compatible peripherals, designed for data transfer up to 480 Mbps. This type of port is convenient for basic tasks where high speed isn't necessary, but it significantly falls behind more modern USB versions for very large files and fast external drives. The major advantage here is compatibility: USB-A 2.0 has long remained the most familiar format for mass accessories.

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.

The device has its own external screen. Such a screen has a small size and performs an auxiliary role; various additional information can be displayed on it: operating mode, selected media, file name and location, playback time, etc.
