line-rate conversion
A translation of standardized, existing video systems (using 525, 625, and 1125 total lines per frame) to proposed systems. Note: Current systems operate in a 2:1 interlace mode, i.e., with 262.5, 312.5, 562.5 lines per field and with concurrent temporal differences at field rates of 50.00, 59.94, or 60.00 fields per second. While simple transcoding by deletion or repetition can be applied, it is more commonly done by applying an algorithm to stored information in order to generate predictive line structures in the target system. [After SMPTE]
