<p>The invention relates to the ability to receive data from a remote source which is transmitted to a broadcast data receiver at a location for use. The data which is transmitted includes at least video data which is used in the generation of a television programme and/or other material which is displayed on screen. A user is provided with a control means or control capability to freeze or stop the video display at a particular frame on screen and, when the display is stopped, select a portion of the display on screen. The data for the selected portion is identified by the broadcast data receiver or by apparatus connected to the receiver and processed to develop a new on-screen display for the selected portion only and to a scale which is either predefined or selected by the user. In addition, algorithms may be used in the reprocessing of the data for the selected portion to allow the display which is generated to have improved image characteristics.</p> |
