The layouts of common container formats: AVI, Matroska and PDF. Although containers may identify how data or metadata is encoded, they do not actually provide instructions about how to decode that data. A program that can open a container must also use an appropriate codec to decode its contents. If the program doesn't have the required ...

Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.

Many C compilers, including GCC, define a multi-character literal behavior of right-aligning to the least significant byte, so that '1234' becomes 0x31323334 in ASCII. [10] This is the conventional way of writing FourCC codes used by Mac OS programmers for OSType. (Classic Mac OS was exclusively big-endian.)
Free software implementations often lack features such as encryption and region coding due to licensing restrictions issues, and depending on the demands of the DVD producer, may not be considered suitable for mass-market use.
