How JTBC Keeps Pace with YouTube Trends: Dalpha's Subtitle Generation and Translation AI

JTBC is a leading Korean integrated media group spanning broadcasting, digital, and news, and it is at the forefront of online distribution of diverse video content and digital innovation.

Why They Adopted It: Fast Translation That Keeps Up with YouTube Trends

To run YouTube content that responds nimbly to trends and to drive the globalizationof its content at low cost and high speed, the JTBC Digital Service Team discovered the DALPHA team—which solves business problems with custom AI solutions—and launched a project together.

The AI Solution: Automatic Subtitle Generation and Translation AI

To solve this challenge, the JTBC Digital Service Team worked with Dalpha to adopt an AI-based subtitle generation and translation solution that staff can use directly.

Once you upload the original video and select the desired subtitle format (Korean / English / simultaneous Korean-English), the AI automatically generates the subtitles. By having the AI learn the special terminologyspecific to each program, translation errors were reduced and accuracy was improved.

As a result, the JTBC Digital Service Team can now create subtitles instantly and easily, whenever they want.

The Impact: Drastically Reduced Time and Lower Costs

Since adopting the AI solution, staff have expressed high satisfaction with the quality of the subtitle translations.

Instant processing secured the right timing for using content. When using existing outsourced labor, it took an average of more than 24 hours per video, but after adopting the AI solution, the work is now completed in roughly the same time as the video's running time (e.g., a 1-hour video = about 1 hour). This made it possible to upload content immediatelyat the desired moment.

Along with the work speed, costs were also reduced. Compared to before, the per-minute unit price dropped to about one-fifth the level.

In this way, the JTBC Digital Service Team has built a more agile and efficient content operation environment through the adoption of a custom AI solution.

Content operations, too, can be improved through AI in a way that 'reduces both time and cost at once.'
