To help facilitate embedding of our static HTML chyron summary chronologies in iframes, they now support a variant of the cross-domain postMessage resizer model we use for the DOC 2.0 and TV 2.0 APIs. The postMessage model used in the chyron pages assumes static page content, unlike the dynamic content reorganizing of the DOC and TV APIs and thus relies on a single onload update. The extreme width of the displays and requirement for side-by-side display even on width-constrained devices means the chyron postMessage model is slightly different from the DOC/TV 2.0 API models in that it also transmits the content width and uses separate metrics for height and width. See the underlying code used in the Chyron Browser for the latest iteration of this framework model.
