Examples of TVIs

  • An electrical waveform was generated by a microphone during a live TV show and sampled at 48kHz, 24-bits per sample. Two alternative TDSs were generated from the data: one with PCM Data Objects and one with FLAC Data Objects. Both TDSs were associated with the same TVI.
  • Two devices were connected to a wind speed meter during a sailing race. One produced a TDS containing a Data Object every 10 seconds – each Data Object encoded the wind speed using JSON. The other produced a TDS containing a Data Object every 15 seconds – each Data Object encoded the wind speed using XML. Both TDSs were associated with the same TVI.
  • A scene during a play has automated lighting. Two alternative TDSs were created to describe how the lights should change over time during the scene. During each production of this scene, either TDS can be used to automatically control the lighting. One TDS contains a Data Object every 0.5 seconds – each Data Object encodes (as XML) the list of lights that are on at the associated Time Value. The other TDS contains a Data Object only when a light changes state – each Data Object encodes (as XML) details of which light(s) has changed and the new state of the light (on/off). Both TDSs are associated with the same TVI.
  • A jingle for a live radio show is created in an editing tool using a variety of pre-recorded music, speech, etc. The finished jingle is exported twice (creating two TDSs): as a WAV file (uncompressed audio) and as an MP3 file (compressed audio). Either file can be used when the jingle is required. Both of these TDSs are associated with the same TVI.
