VOB vs AAC:
| Name | VOB | AAC |
| Full name | Video Object | Advanced Audio Coding |
| File extension | .vob | .aac |
| MIME | video/dvd, video/x-ms-vob | audio/aac |
| Developed by | DVD Forum | Bell Labs, Fraunhofer Institute etc. |
| Type of format | Media container | Audio compression format |
| Introduction | VOB (Video Object) is the container format in DVD-Video media. VOB can contain digital video, digital audio, subtitles, DVD menus and navigation contents multiplexed together into a stream form. Files in VOB format may be encrypted. | Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. AAC has been standardized by ISO and IEC, as part of the MPEG-2 and MPEG-4 specifications. |
| Technical details | Files in VOB format have a .vob filename extension and are typically stored in the VIDEO_TS directory at the root of a DVD. The VOB format is based on the MPEG program stream format, but with additional limitations and specifications in the private streams. VOB files may be accompanied with IFO and BUP files. These files respectively have .ifo and .bup filename extensions. | AAC supports inclusion of 48 full-bandwidth audio channels in one stream plus 16 low frequency effects channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode; however, hi-fi transparency demands data rates of at least 128 kbit/s. |
