Broadcast Delivery

Broadcast delivery in South Korea rests on the ATSC 3.0 terrestrial framework used nationwide. It also follows the published tech specs of the four major free-to-air networks: KBS, MBC, SBS, and JTBC, plus the cable and satellite operators that distribute through them. Each network keeps its own ingest profile. That profile sets the accepted codecs, container formats, audio channel mapping, loudness targets, captioning workflow, and metadata schema. Our delivery team holds the current spec sheet for each one and builds masters to match. As a result, files clear tech sign-off on the first try, with no rejection notes that put air dates at risk.

Some global networks take Korean content under licence, whether North American cable, European public TV, or pan-Asian operators. For them we run dual-standard delivery. That covers both the home Korean master and the local global version. PAL, NTSC, and HD frame-rate changes use motion-compensated processing rather than simple frame doubling. Audio is remixed to R128 or OP-59 loudness based on where it is bound.

Closed-caption and subtitle files are recut to the container that each receiving network prefers. Automated QC runs then sit alongside manual review by our team. Each package ships with a written compliance report. That report logs video levels, audio loudness, safe-area checks, and full metadata, so the receiving network can sign off with no back-and-forth.
