Opening a TLV File
The TLV file type is primarily associated with VLC.
What is a TLV file?
TLV files mostly belong to VLC. TLV Files use a Type-Length-Value encoding scheme. Each data block holds a tag (type), a byte count (length), and the actual content (value).
These files are used in several ways:Video Containers - Some TLV files are part of AVI video files using the RIFF format. They store video data along with extra tagged metadata. See Audio Video Interleave details. Metadata Storage - Other TLV files hold navigation or configuration information. For example, they serve as TomTom metadata files and are used to encode data in a Tag Length Value format. Network and System Data - TLV files may also contain items like Cisco Trust List values, data for communication protocols, tax or legal voucher information, and files used by animation software like OpenToonz (with support from tools such as Wireshark) or cash registers like the Casio QT-6100. The structure allows systems to add, remove, or update specific data segments without altering the overall file design. To view a TLV file, you need to use the proper application. For example, if it is an AVI video using tagged data, a program like VLC may open it, whereas metadata files may require specialized software (such as TomTom Home or Cisco Unified Communications Manager).

Programs that open and convert TLV files:
- VLC
See the previous paragraphs to learn more about the main application. TLV files are often referred to as VLC encodeds because this type of file is primarily created or used by this software.
- TruLASER View (Geometry Data) by Magestic Systems, Inc.TruLASER View projects laser-accurate fabricating information on any 2D or 3D surface. Information from any CAD system can be laser projected. This is a proprietary data format used in creating data for laser projection systems used in manufacturing. The Mime types used with this association are: application/trulaser. The identifying characters used for this association are - Hex: 4B 04, ASCII: K. This file format is classified as CAD/CAM. Program ID is TLVfile
TLV file extension format:
If you can determine the file format, the associated program can also be determined. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. File extension, signature and file format must match; otherwise errors will occur when the file is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. In the following you will find our evaluation of the TLV files:
Files with the TLV extension are quite widely used. This file type includes different formats for the applicable programs. The following file formats are most commonly found in TLV files:
- 35% of all TLV files are using the well-known RIFF file format to store the data. RIFF files store data in tagged chunks. There are primarily used to store multimedia such as sound and video. If you open these files in a text editor, you will see only illegible characters. A typical file size is 300 MB. This file type is based on cutting-edge technology. Several words can almost always be found in the files, e.g. LIST!, MJPG, hdrlavih8, strf(, strlstrh@, vidsMJPG, RIFF and AVI LIST. The following filename is common: 20180601AA.TLV or 20180601AB.TLV.
- 20% of all TLV files do not have a standard signature. The content consists of readable text data, which can be read using a text editor. TLV files are between 380 bytes and 2 KB in size. Several words can almost always be found in the files, e.g. 1http://home.tomtom.com/tlvvocabulary/itemmetadata, 7http, http://num1.id.tomtom.com/, text/plaind and http://id.sharing.tomtom.com/anonymous/. The file name Application.tlv or splashw.tlv is typical for these files. These files are often associated with safety, internet, connect, premium, splash and meta.
All other TLV files (45%) have different formats, the following 8 formats exist: TLV and ECR. Often described as request, hello, data, apbtfw, config, crbtfw or itlsep.
