Abstract
A video receiver is provided having a screen forecast journal with teletext data, collected from different broadcast stations and continuously updated with text pages at preset time intervals. The data is arranged in tables by programme identification and page identification and stored in memory devices, for accessing at any time. The page identifications are allocated to the programme slots, i.e. one programme identification with a page number each time. The tables can be accessed by page numbers for programmes not being transmitted at that time. A programme identification/page identification table proves beneficial for programming such page identifications. Pages are referenced by moving a cursor to margin areas of a text page. All programmes in the same time period can be paged through. Telecasts to be recorded can be selected from the pages of the forecast journal. Telecast data is transferred on a timer memory device. In this memory device, telecasts are marked (flagged) as soon as they are recorded completely. Either only flagged or only unflagged broadcasts can be displayed. A timer table can show marked (recorded) and/or unmarked (not yet recorded) telecasts, to function as a video library, which can also show the information, regarding which cassette contains the individual telecast previously recorded. In addition to the recording data, and cassette number information, the system is also capable of copying the individual telecast titles from the forecast page, and entering them into the video library, for ease of identification for later replay purposes.

3. Video receiver, characterised by
a tuner which is adjustable to a preset TV programme by means of programme identification signals, a text decoder which can be driven by page number signals for decoding text data when it is transmitted in TV signals, arranged according to pages, a page selector device for selecting a text page by setting the tuner and text decoder, depending on a specific programme identification and a specific page number, a programme slot selection device for updating one of several programme slots at a time, a page identification memory device for storing page identifications, each of which comprises a programme identification and a page number, and a page identification retrieval device (CPU) for retrieving page identifications, irrespective of the programme slot, and for outputting each page identification retrieved to the tuner and decoder, whereby, depending on each programme identification retrieved at the same time as the page identification, such pages can also be selected, but whose programme identification is not identical with the programme identification of the activated programme slot.
-
4. Video receiver, characterised by
a tuner which is adjustable to a preset TV programme by means of programme identification signals, a text decoder which can be driven by page number signals for decoding text data when it is transmitted in TV signals, arranged according to pages, and a programme identification/page identification table, which stores at least one page identification, assigned to one of several programme identifications in each case, whereby each page identification comprises one programme identification and one page number.

5. Video receiver, characterised by
a tuner which is adjustable to a preset TV programme by means of programme identification signals, a text decoder which can be driven by page number signals for decoding text data when it is transmitted in TV signals, arranged according to pages, a picture generator for producing cursor symbol data for a cursor and picture page data from the decoded text page data and for outputting decoded picture data, either from a text page memory device or direct from the text decoder, to a screen whereby the picture data to be displayed is such that every text page is surrounded by a margin on all four edges when displayed, a cursor control device for positioning the cursor within the field of the picture to be displayed and for triggering specific procedures when a preset key is pressed, and a page switchover device, for switching over to a page of a higher number when the cursor is positioned in the first of the four picture margins and then the preset key is pressed, for switching over to a page of a lower number when the cursor is positioned in the second of the four picture margins and then the preset key is pressed, whereby the second picture margin runs parallel to the first picture margin, for switching over to a programme of a higher number and from there to a specified page number when the cursor is positioned in the third of the four page margins and then the preset key is pressed, whereby the third picture margin runs at a right-angle to the first picture margin, and for switching over to a programme of a lower number and from there to a specified page number when the cursor is positioned in the fourth of the four picture margins and then the preset key is pressed, whereby the fourth picture margin runs parallel to the third picture margin.

6. Video receiver, characterised by
a tuner which can be set to a preset TV programme by means of programme identification signals, a text decoder which can be driven by page number signals for decoding text data when it is transmitted in TV signals, arranged according to pages, a picture generator for producing cursor symbol data for a cursor and picture page data from the decoded text page data and for outputting decoded picture data, either from a text page memory device or direct from the text decoder, to a screen, a cursor control device for positioning the cursor within the field of the picture to be displayed and for triggering specific procedures when a preset key is pressed, and a page switchover device, for switching over text pages from one programme to text pages from another programme, whereby, if broadcast pages are present as text pages containing time information, the first broadcast page selected in a programme attained by switching over is that which contains the information in the period in which that time occurs corresponding to respective time information at which the cursor is displayed in the broadcast page before switchover to text pages from another programme.
