Determining subtitle synchronization when compared to audio track

An apparatus for determining a level of synchronicity between subtitle text in audiovisual content and speech that would be heard during display of the audiovisual content, the apparatus comprising:

• a network communication unit configured to transmit and receive data;
• and
• one or more controllers configured to:
• access a first binary sequence, each bit of the first binary sequence indicating whether the speech is provided at a respective sampling time of a plurality of sampling times;
• access a second binary sequence, each bit of the second binary sequence indicating whether the subtitle text is provided at a respective sampling time of a plurality of sampling times;
• and
• compare the first binary sequence and the second binary sequence to determine the level of synchronicity between the subtitle text and the speech.

A machine-readable non-transitory medium having stored thereon machine-executable instructions for determining a level of synchronicity between subtitle text in audiovisual content and speech that would be heard during display of the audiovisual content, the instructions comprising:

• accessing a first binary sequence, each bit of the first binary sequence indicating whether the speech is provided at a respective sampling time of a plurality of sampling times;
• accessing a second binary sequence, each bit of the second binary sequence indicating whether the subtitle text is provided at a respective sampling time of a plurality of sampling times;
• and
• comparing the first binary sequence and the second binary sequence to determine the level of synchronicity between the subtitle text and the speech.
