Closed Caption (CC) and XDS (VChip/CGMS-A) Existence Test

AutoCheck supports NTSC caption data (Closed Caption and/or XDS data) carried over the following user data formats:
  • ATSC-A53/EIA-708
  • SCTE-20
  • Dish Network
  • Omneon
This test checks the existence of the following contents:
  • EIA/CEA-608 CC
  • EIA/CEA-708 CC
  • XDS VChip/Content Advisory
  • XDS CGMS-A

Note: When the carrier data format is ATSC-A53/EIA-708, only NTSC caption data are actually decoded and displayed. Currently DTV-CC is only checked for existence.

Note: This test is only available with the VOD CEP 2.0 license. Currently this test is only applicable to MPEG-2 video. Support for auxiliary data carried within H.264/AVC and VC-1 are pending finalization of the specifications.

    • Program stream map
    • PES header
  • Analysis of the P-STD buffer for both audio and video elementary streams.

VOD CEP Compliance Test

VOD CEP compliance test is only applicable to MPEG-2 TS streams that contains MPEG-2 video (MPEG Audio is optional for HD profile). This test performs the following tests according to CableLabs VOD Content Encoding Profiles 2.0 Specification:

  • Video Encoding Specification
  • Closed Captioning/V-Chip SpecificationNote: This test is the same as the CC and XDS Existence Test
  • Audio Encoding Specification
  • MPEG-2 Systems Constraints
    • Video PES Constraints
    • Transport Stream Constraints
    • Transport Bitrate constraints
    • PSI Constraints
    • PID Value Constraints
  • Standard Definition (SD) Encoding Constraints
  • High Definition (HD) Encoding Constraints

Note: Transport stream tests and MPEG-2 video conformance tests are also required.

Note: Metadata specification test is not included.

Note: Usage of ANSI/SCTE 35 test is not included.

MPEG-2/MPEG-1 Video Conformance

  • MPEG-2/MPEG-1 video conformance testThis test checks semantic rules and data integrity according to ISO/IEC 13818-2 (ISO/IEC 11172-2 for MPEG-1)
  • Video Buffering Verifier (VBV) conformance testThis test checks for bit rate and buffer occupancy violations according to Annex C of ISO/IEC 13818-2

MPEG-4 v2 /H.263 Video Conformance

  • MPEG-4 v2 video conformance testThis test checks semantic rules and data integrity according to ISO/IEC 14496-2 (v2)Note: H.263 baseline is the same as MPEG-4 short video header video
  • Video Buffering Verifier (VBV) testThis test checks for bit rate and buffer occupancy violations according to Annex D of ISO/IEC 14496-2 (Only Video Rate Buffer Model is tested).Note: Since the bit stream delivery rate function, R(t), is typically not defined within MPEG-4 video itself, only constant bitrate R(t) and MPEG-2 style variable bitrate R(t) can be tested (See Annex C of ISO/IEC 13818-2). If the MPEG-4 video is carried over MPEG-2 TS/PS stream, then STD Buffer Model test is more appropriate since R(t) is defined at TS/PS level in this case.

H.264/AVC Video Conformance

  • H.264/AVC video conformance testThis test checks semantic rules and data integrity according to ITU-T H.264
  • Hypothetical Reference Decoder (HRD) conformance testThis test checks for bitstream HRD conformance according to Annex C of ITU-T H.264

SMPTE VC-1 Video Conformance

  • SMPTE VC-1 conformance testThis test checks semantic rules and data integrity according to SMPTE 421M
  • Hypothetical Reference Decoder (HRD) conformance testThis test checks for bitstream HRD conformance according to Annex C of SMPTE 421M

Audio Level Test

  • Silence Detection
  • Max Level Detection
  • Digital Clipping Detection
