High-definition television (HDTV) uses 720p (progressive), 1080i (interlaced), and 1080p (progressive, also known as Full-HD). In digital video, the temporal sampling rate is defined as the frame rate – or rather the field rate – rather than the notional pixel clock. The image sampling frequency is the repetition rate of the sensor ...
In newer vision mixers, the DVE is integrated into the vision mixer; older models without built-in DVEs can often control external DVE devices, or an external DVE can be manually run by an operator. Hard drive or SSD docking stations or memory card readers. A still store, or still frame, device for storage of graphics or other images.
Generator locking can be used to synchronize as few as two isolated sources (e.g., a television camera and a videotape machine feeding a vision mixer (production switcher)), or in a wider facility where all the video sources are locked to a single synchronizing pulse generator (e.g., a fast-paced sporting event featuring multiple cameras and recording devices).
