Ad insertion monitoring

  • The Splice_null() command does not transmit any data and is used to check for responses from the receiver devices. In addition, a periodic insertion of this command makes it possible to avoid activating TR101290 PID_error triggers.
  • The Bandwidth reservation() command requests additional bandwidth from the compression system to be used for transmitting an elementary PID stream with SCTE-35 messages.
  • The Time_signal() command transmits the precise timestamps that the receiver devices use to synchronize their operation with the sender devices.
  • The Private_command() can be used to transmit other types of data not mentioned in the SCTE-104/35 specifications.
  • The splicer must insert the ad precisely at the time specified in the SCTE-35 marker and not one frame earlier or later
  • The ad insert must not differ from the main stream in its structure (such as codec/bitrate/GOP/volume etc.)
  • The ad insert must start strictly from the I frame, otherwise the first GOP of the insert will be corrupted.
