Format VOB
The VOB (Video Object) format is a type of file developed for DVD-Video, introduced in 1995 by the DVD Consortium (now known as the DVD Forum). These files are essentially multimedia containers based on the MPEG-2 format, specifically designed to organize and store the content of video DVDs.
A VOB file can simultaneously contain several data streams: video, audio (potentially including multiple tracks in different languages), subtitles, and menus. The video is generally encoded in DVD quality with a standard resolution of 720×480 pixels (NTSC) or 720×576 pixels (PAL), while the audio may be in AC-3 or DTS format. This versatility makes it a format particularly suitable for commercial and personal DVDs.
VOB files are typically accompanied by IFO (information) and BUP (backup) files that contain the necessary metadata for DVD navigation, such as chapter structures and playback settings. A peculiarity of VOB is its size limitation to 1 GB, which explains why a movie is often divided into several files (VTS_01_1.VOB, VTS_01_2.VOB, etc.). Although this format remains widely used for DVDs, it has been gradually supplanted by more modern formats such as Blu-ray for high-definition content. VOB file playback is now supported by most media players, although certain copy protection measures may sometimes limit their accessibility.
Format M4V
The M4V format, developed by Apple, is a variant of the MP4 container specifically designed for iOS devices and the iTunes ecosystem. This format was created to allow the secure distribution of digital video content via the iTunes Store.
Technically, the M4V uses the same framework as the standard MP4, based on the MPEG-4 Part 14 container. It can contain videos encoded in H.264/AVC, AAC audio tracks, subtitles, and chapters. The main difference lies in its ability to integrate Apple's FairPlay protection system, thus allowing content creators to control the distribution of their works.
M4V files are particularly popular within the Apple ecosystem, being the default format for movies and TV shows purchased on iTunes. They offer excellent image quality and efficient compression, making them a wise choice for streaming and storing video content. However, their main limitation is their restricted compatibility outside the Apple ecosystem. M4V files protected by DRM can only be played on authorized devices, although unprotected versions can be converted and played on other platforms.
This format remains widely used today, particularly for professional content distribution and the sharing of personal videos between Apple devices, even though current trends favor more universal formats for online streaming.
