Television program length indicator
View Patent ↗The invention relates to a television or electronic program guide (EPG) of the type which is displayed on the screen of a television set to indicate channels, and programs, which are available for viewing over a time period indicated by a time bar ( 4 ). In accordance with the invention the length of the program is indicated by a cell in a displayed grid ( 2 ) and, if the program has started or will finish prior to or after the time period displayed, a display is generated which indicates to the viewer the time which has lapsed since the program started or the time remaining of the program.
1. A method of generating a television program guide, said television guide including at least one display page comprising a grid including the following steps:
generating said grid by providing a time bar, a series of cells, each cell indicating a program to be shown on a particular channel over the time period displayed, and the size of each cell indicating the start, finish and length of each program with respect to the time bar;
calculating for each of the cells difference between the start time of the time bar and the start time of the program when at least one or more programs indicated by one or more corresponding cells within the grid starts outside the time period displayed;
calculating for each of the cells difference between the end time of the time bar and the finish time of the program when at least one or more programs indicated by one or more corresponding cells within the grid finishes outside the time period displayed; and
generating a display portion displaying the difference with respect to the program cell on the display for each of the programs which start or finish outside the time period displayed, wherein the display portion is generated simultaneously for two or more cells within the grid.
2. A method of generating a television guide display according to claim 1 wherein the display portion is provided as an additional portion of the cell so that those cells which indicate programs which have started or will finish outside the time period which is displayed on the display page, will protrude from the appropriate side edge of the grid and, in said additional portion, will be displayed the time which has elapsed or will lapse from the start or before the finish of the program as appropriate.
3. A method according to claim 1 including the step of transmitting the calculation, and data relating to the calculation, from a broadcaster at a remote location to a broadcast data receiver so that, during the processing of the data, the broadcast data receiver can generate the display page to include said display portions.
