R&S®DV-TCM Test Card M-Streams

Applications

This collection contains several transport streams in line with the DVB as well as with the ATSC standard and allows a large variety of tests to both standards.

Tests on elementary video stream:

  • Use of active format descriptor AFD2)
    • Correct aspect ratio (4:3, 16:9, ¾ subsample, ¼ subsample, shoot & protect)
    • Dynamic format selection
    • Placing the AFD in sequence header, GOP header or picture header
  • Decoding sequence of the group of pictures2)
    • I-frame only
    • Long GOP
  • Decoding of various coding formats2)
    • Colour display
    • Linearity
    • Interlacing
    • Two-dimensional frequency response
    • Picture geometry

Tests on elementary audio stream

  • Decoding of various coding formats2
    • MPEG-1 Layer II
    • AC-3 5.1 surround
  • Left-right identification
  • Synchronisation with video

Tests on elementary data stream

  • DVB subtitling
    • Decoding
    • Synchronism with video

DVB-specific tests (SI)

  • Use of linkage descriptor

ATSC-specific tests (PSIP)

  • Identification of transport stream syntax:
    • Identification of audio channel language
  • Extended text table (ETT)
    • Use of table (linkage to event information table EIT)
    • Huffman decoding

    1Realtime calculation of all time-relevant parameters ensures error-free replay even at the transition from the start to the end of the stored sequence. This refers to the transport stream syntax as well as to the elementary streams.

    2The associated transport streams partly contain tables of one standard only (DVB or ATSC); the video and audio formats are selected according to the standard (see below).
