    MPEG-2 is used in Digital Video Broadcast and DVDs. The MPEG transport stream, TS, and MPEG program stream, PS, are container formats.. MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". [1]

    H.262 [2] or MPEG-2 Part 2 (formally known as ITU-T Recommendation H.262 and ISO/IEC 13818-2, [3] also known as MPEG-2 Video) is a video coding format standardised and jointly maintained by ITU-T Study Group 16 Video Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG), and developed with the involvement of many companies.

    Note that operating system support does not mean whether video encoded with the codec can be played back on the particular operating system – for example, video encoded with the DivX codec is playable on Unix-like systems using free MPEG-4 ASP decoders (FFmpeg MPEG-4 or Xvid), but the DivX codec (which is a software product) is only available ...

  5. Video compression picture types - Wikipedia

    en.wikipedia.org/wiki/Video_compression_picture...

    Older standard designs (such as MPEG-2) use only one previously decoded picture as a reference during decoding, and require that picture to also precede the P picture in display order. In H.264, can use multiple previously decoded pictures as references during decoding, and can have any arbitrary display-order relationship relative to the ...

  6. MPEG transport stream - Wikipedia

    en.wikipedia.org/wiki/MPEG_transport_stream

    To enable a decoder to present synchronized content, such as audio tracks matching the associated video, at least once each 100 ms, a program clock reference (PCR) is transmitted in the adaptation field of an MPEG-2 transport stream packet. The PID with the PCR for an MPEG-2 program is identified by the pcr_pid value in

  7. Reference frame (video) - Wikipedia

    en.wikipedia.org/wiki/Reference_frame_(video)

    Reference frames are frames of a compressed video that are used to define future frames. As such, they are only used in inter-frame compression techniques. In older video encoding standards, such as MPEG-2, only one reference frame – the previous frame – was used for P-frames. Two reference frames (one past and one future) were used for B ...

    Absent such a licence from the MPEG Licensing Authority, it could possibly be illegal in certain countries to distribute compiled versions of libmpeg2 for the purpose of decoding MPEG-1 and/or MPEG-2 video streams. In February 2018, all MPEG-2 patents have expired for any country except Malaysia and the Philippines. [1]
