AVB can represent different things based on what environment it appears in, and for the .AVB extension the usual meaning is an Avid Bin used by Avid Media Composer to hold metadata about clips, subclips, sequences, and markers while the actual media sits elsewhere like in `Avid MediaFiles\MXF`; this bin isn’t meant to be opened with normal tools and must be loaded inside Avid, where offline items usually signal path mismatches rather than a broken bin, while other uses of "AVB" in networking or
Android security don’t refer to openable files at all.
In certain A/V and automotive Ethernet systems, AVB commonly refers to Audio Video Bridging, an IEEE standard set focused on synchronization and guaranteed bandwidth for streaming media, which relates to networking rather than file types; meanwhile in Android modding, AVB is Android Verified Boot, a security layer validating partitions at boot via items like `vbmeta`, and in older, uncommon software, `.avb` might also appear as a Microsoft Comic Chat Character file if the source isn’t Avid.
How an AVB file is opened depends on the AVB definition relevant to you, but for Avid Bin files (.avb), the correct method is to launch Avid Media Composer, load the right project, and open the bin inside Avid, where its items display as part of the project; Media Offline almost always means missing or unlinked `Avid MediaFiles\MXF` rather than a damaged bin, so reconnection or relinking is the fix, and bin corruption is often resolved by restoring a recent backup from Avid Attic.
If your "AVB" refers to Audio Video Bridging networking, there generally isn’t any single openable file because AVB describes Ethernet timing/streaming standards, meaning you configure AVB-capable hardware, switches, and drivers rather than open an AVB document; if your "AVB" comes from Android Verified Boot, "opening" instead involves firmware images and verification data like `vbmeta` that you inspect with developer tools, and if the `.avb` is the rare Microsoft Comic Chat Character type, you’d need original Microsoft software or a legacy viewer since modern systems don’t support it.

An Avid Bin (`.avb`) is not a self-contained media file, because it’s meant purely as metadata describing what clips exist, how sequences are arranged, which timecode portions you used, and what markers you placed, while the heavy media resides in MXF directories like `Avid MediaFiles\MXF\...`; if you copy only the `.avb`, you’re just moving the edit blueprint, not the underlying media, so Avid will open it but show Media Offline until media is connected or relinked, and this architecture keeps bins small and shareable—so an `.
