These registers are also cleared when the SMPTE_BYPASS pin is LOW, or the LOCKED pin is LOW. Note 1: The Line Numbers in brackets refer to Version zero SMPTE ST 352 packet locations, if they are different from the Version one locations. Note 2: 3G formats cannot be fully determined from these measurements. Their detailed information will be derived from SMPTE ST 352 packets, which must be in the video stream as a mandatory requirement of the SMPTE ST 424 specification, as described below.
