Definitions

  • FIG. 7A and FIG. 7B are diagrams showing memory management of the DPB.
  • picture data for a plurality of frames can be stored in the DPB.
  • picture data for four frames can be stored.
  • two types of areas can be set: a long term memory; and a short term memory.
  • the picture data stored in short term memories are bumped out sequentially from a picture of the earliest decoding order.
  • the non-referenced picture B indicates a B picture which is not referred by other pictures
  • the reference B picture indicates a B picture referred by other pictures.
  • arrows indicate predictive structures.
  • P9 indicates that it refers to P5 and II
  • B2 refers to II and Br3
  • Br3 refers to II and P5.
  • the P pictures only refer to the I pictures or the P pictures so that the reference B picture is not referred.
  • FIG. 8(b) shows pictures shown in FIG. 8(a), arranged in decoding order.
  • Brll it is assumed that a memory management command for transferring II to a long term memory is stored in header information of ' slices which constitute a picture.
  • step S1004 the picture data is coded and the processing moves on to step S1005.
  • step S1005 it is judged whether or not a memory management command is issued to the current picture. If the command is issued, the processing moves on to step S1006, and moves on to step S1008 if the command is not issued.
  • step S1006 it is judged whether or not the current picture is the reference B picture. If the picture is the reference B picture, the processing moves on to step S1007, and moves on to step S1008 if it is not.
  • the decoding apparatus 2000 includes a picture type obtaining, unit 2001, a decoding judgement unit 2002, a management command analyzing unit 2003, a DPB 2004 and a decoding unit 2005.
  • coded data Vin is inputted to the picture type obtaining unit 2001.
  • the picture type obtainment unit 2001 obtains a picture type of a picture by detecting a picture boundary from the coded data Vin, and inputs the picture type Ptd into the decoding judgement unit 2002.
  • the decoding judgement unit 2002 judges, based on the picture type Ptd, whether or not to decode the picture, and inputs the judgement result Rep into the management command analyzing unit 2003 and the decoding unit 2005.
  • the support information HLP may indicate whether or not to satisfy constraints defined in a communication service such as downloading and streaming, or broadcast standard.
  • the support information HLP may indicate both information shown in FIG. 19A and FIG. 19B.
  • the BD disc has a recording area in a spiral form from the inner radium toward the outer radius as similar to, for example, DVD, CD and the like, and has a logical address space in which logical data can be recorded between a lead-in of the inner radium and a lead-out of the outer radium. Also, there is a special area inside the lead-in which is read only by a drive called a Burst Cutting Area (BCA). This area cannot be read from the application so that it may be used, for example, for a copyright protection technology and the like.
  • application data ⁇ such as video data lead by the final system information (volume) is recorded.
  • the file system is a UDF, an ISO96660 and the like.
  • a time map is a table having information for each VOBU.
  • the table includes the number of VOBU (Number) held by said VOB and each VOBU information (VOBU#l to VOBU#n).
  • Each of the VOBU information is made up of an address I_start of an address of a VOBU leading TS packet (I picture start), an offset0 address (I#end) until the end address of the I picture, and a playback start time (PTS) of the I picture.
