No need to worry. For network provided programming
The 4 major TV networks have used 1080p cameras for studio and live sports productions for years. However, even though the cameras shoot in progressive 1080p, the networks compress and broadcast these signals in older 1080i or 720p formats to consumers.
Major networks like ABC, CBS, NBC, and FOX have relied on high-end, 1080p and 4K-capable Sony or Grass Valley studio cameras for well over a decade. In fact, even when covering fast-paced sports, they often use higher-resolution cameras and downscale the feed for the viewer.
