Live captions and
in-picture ads, on your existing chain.
Point Media Tech's live production innovation adds two capabilities alongside your existing production chain: real-time Speech-to-Text captions, and ScoreCast AD in-picture sponsor placements triggered at peak moments, with Kaster View and Caster handling monitoring and public-internet transport. It fits news, election nights, New Year's specials, esports, and sports, so regional broadcasters and league producers can adopt it without replacing their plant.

Once AI, live captions, and IP transport matured,
live innovation became a software job.
Live captions and in-picture ads can now be built in software on GPUs, with no dedicated hardware. Three things matured at once: AI detection of picture and audio events runs in real time on live feeds, live speech captions reached a quality viewers can actually read, and SRT- and RIST-based public-internet transport is now routine in sports and news.
For live producers, that changes two things. First, in-picture ad compositing, multilingual live captions, and multi-signal monitoring can run as software on GPUs at regional broadcasters, league-owned production, and esports teams, connected in bypass to the existing SDI chain. Second, inventory gains new positions: venue signage and inning breaks are finite, while in-picture placements at the peak of play, and the new audiences captions bring in, are separate line items to sell.
Regulation is pushing the same way. Caption accessibility requirements across the EU, North America, and parts of Asia keep tightening, and live captioning has moved from a premium feature to baseline.

From live captions to in-picture ads,
five products forming the live innovation stack.
- ScoreCast ADAI detects high-emotion moments in a live feed and places sponsors into in-picture positions such as the scorebug, bugs, and lower banners; in the anonymized WBC case the average trigger latency was 0.8 s.
- CatchUp AIViewers ask for any moment in plain language inside your OTT app and get highlights at the length they choose; a live reel updates during the match so late joiners can catch up.
- Speech-to-TextReal-time captioning across 40+ languages, production-ready for news, sports, and live entertainment; outputs CEA-608/708, TTML, and WebVTT straight to Playout and Marquee.
- Kaster ViewWeb multiviewer that brings SRT, MPEG-TS, HLS and DASH sources onto one wall in the browser, with black-frame, freeze, silence and signal-loss alarms in an alarm queue, replacing fixed MCR hardware walls.
- Caster Public-Net TransportSRT-based contribution and distribution over the public internet, with ARQ retransmission, FEC, and AES encryption, suited to remote production and temporary venues.
Sports channel × 2026 WBC
A major sports channel deployed ScoreCast AD for its 2026 World Baseball Classic coverage. AI triggered sponsors' in-picture placements at strikeouts, scoring plays, and other high-emotion moments in Team Taiwan's games, overlaid on the scorebug and name straps without cutting away from play. Over the tournament it identified 327 high-emotion moments, with a 0.8 s average trigger latency and 2.4× the contextual precision of conventional inning-break ads.

How do in-picture ads differ from traditional ad breaks?
In-picture ads overlay the sponsor on the scorebug, a bug, or a lower banner without cutting away from the programme. A traditional break cuts away to play a spot. Point Media Tech's ScoreCast AD triggers these placements at high-emotion moments; in the anonymized WBC case their contextual precision was 2.4× that of conventional inning-break ads.
Beyond accessibility, what do live captions add to a broadcast?
Point Media Tech's Speech-to-Text live captions let a live show reach deaf and hard-of-hearing viewers and people watching muted on mobile. The transcript can be written into MAM, so highlights and replays can later be found by keyword.
How do live captions connect to an existing live playout workflow?
Point Media Tech's Speech-to-Text takes audio from SDI, NDI, RTMP, or SRT and outputs CEA-608/708 captions or a live RTMP / SRT caption track. Captions can go to Playout and Marquee for overlay, and to OTT over HLS / DASH.
Do in-picture ads require changes to our production switcher or playout system?
No full replacement is needed: Point Media Tech's ScoreCast AD connects to the broadcast chain in SDI bypass and leaves the existing playout workflow untouched. The anonymized WBC case was deployed this way, and triggers can go out as SCTE-35 cues, REST API calls, webhooks, or GPI / tally to the switcher.
Which live shows suit live captions and in-picture ads?
Any live show with clear peak moments or a need for live captions, such as news, election nights, New Year's specials, esports, and sports. If you need the full sports broadcast chain (OB contribution and multi-output monitoring), see the sports broadcast solution.
