ABSTRACT:
An efficient coding system for interlaced video sequences with forced refreshing capabilities. An input picture of is divided into two fields, a first and a second field. Certain lines or portions of lines in each respective field are designated for forced refreshing, while the non-designated lines are interframe prediction coded. The designated lines of first field are intrafield prediction coded, while the designated lines of the second field are interfield prediction coded. The selection and implementation of the refreshing of the first and second fields is executed by the controller and switching circuitry of the coding system.
