`
`VIDEOTEX FRAME PROCESSING
`
`4,751,669
`
`This application is a continuation in part of [1.8. pa-
`tent application, Ser. No. 595,211, filed Mar. 30. 1984,
`titled Enhanced Videotex Decoder Apparatus.
`BACKGROUND OF THE INVENTION
`
`This invention relates to videotex systems.
`In typical videotex systems, textual and qraphic infor-
`mation from a variety of sources (such as newspapers,
`retailers, or banks) is made available by a videotex sup-
`plier to a large number of subscribers via interactive
`two-way communication over the switched telephone
`network.
`The videotex supplier electronically stores the infor-
`mation supplied by the different sources in the form of
`hundreds of thousands of pages (frames) each represent-
`ing a collection (arranged, for example, in rows and
`columns) of alphanumeric and graphic characters to be
`displayed on a cathode ray tube (CRT) at the subscrib-
`er’s location. Each frame is sent to the subscriber as a
`stream of encoded bytes. Some of the bytes identify the
`particular characters to be displayed. Other bytes are
`essentially instructions about the attributes of the dis—
`played frame, for example, the size of a particular char-
`acter or the background color for a particular line of
`characters. The characters and attribute information are
`translated into the encoded bytes in accordance with a
`set of rules (protocol) applied by each supplier.
`In addition to a CRT, each subscriber has a decoder
`for cenverting the received encoded bytes back to the
`displayable alphanumeric or graphic characters and
`attribute instructions, and a keyboard with which the
`subscriber can tell the videotex supplier what frames to
`send to the subscriber, and can respond to questions
`posed in particular frames.
`\
`Different videotex protocols have been developed in
`different countries. for example Prestel in the United
`Kingdom, Telidon in Canada, and NAPLPS in the
`United States. A description of the Prestel system is set
`forth in Hudson. “Prestel: The Basis of an Evolving
`Videotex System", (BYTE, July, 1983, p. 61), and in
`"Prestel Terminal Specification" updated through
`8/ 1/83, available from Presto! Headquarters. Prestel
`435, Telephone House, Temple Avenue, London EC4Y
`CHI... England. both incorporated herein by reference.
`Some videotex decoders allow the subscriber to
`switch between viewing frames being supplied over the
`telephone line and frames which have been stored lo-
`cally. Frames explaining to the subscriber how to pro-
`ceed may also be displayed.
`SUMMARY OF THE INVENTION
`
`In general. the invention features. in one aspect. appa-
`ratus for locally displaying frames of digital information
`received from a central supplier, including a port con-
`nectable to the central supplier for receiving at least one
`of the informatics: frames from the central supplier, a
`display device for locally displaying at least one of the
`information frames received from the central supplier, as
`storage device for locally storing. after it has been dis-
`played. as a stored frame for later redisplay, at least one
`of the information frames received from the central
`supplier, and a processor connected to be responsive to
`the port and the storage device and comprising means
`for displaying, while the port is connected to the central
`Supplier, an indiCation that the port is connected.

`In preferred embodiments. the means for displaying is
`further arranged to display an indication of the expense
`entailed in the connection, in particular, the time which
`has elapsed during the period since the port was most
`recently connected;
`the indication of expense is dis~
`played on the display device simultaneoust while an
`information frame is being displayed; the processor also
`includs means for enabling the user to selectively ei-
`ther display or not display the indication that the port is
`connected; the means for displaying is further arranged
`to display an indication of whether the information
`frame being displayed is a stored frame from the storage
`device; the processor further includes means for en-
`abling the user to selectively either display or not dis-
`play the indication of whether the information frame
`being displayed is a stored frame from the storage de-
`vice; the means for displaying is further arranged to
`display, while the port is unconnected to the central
`supplier, an indication that the port is unconnected; and
`the apparatus includes a data entry device for enabling
`the entry of data into the apparatus, the data. including
`commands representing actions to be taken with respect
`to the information frames, and the processor includes
`means for delivering to the display device at least one
`menu frame for visually indicating possible actiOns
`which may be taken with respect to the information
`frames.
`including the actions of switching back and
`forth between displaying the information frames as they
`are received from the supplier, and displaying stored
`frames from the storage device, and the processor also
`includes means resp0nsive to the data entry device for
`accepting and executing entered conunands corre—
`sponding to the possible actious.
`Displaying the status line (i.e., the indications that the
`port is connected. and whether or not the displayed
`frame is from the local storage device) reminds the user
`of subscriber fees and telephone tolls being incurred
`while connected to the videotex supplier.
`In another aspect. the invention features apparatus
`for locally displaying frames of digital information re-
`ceived from a videotex supplier, including a port can-
`nectable to the central supplier for receiving at least one
`of the information frames from the supplier, a display
`device for displaying at least one of the information
`frames received from the supplier, and a processor com-
`prising means for delivering to the display device at
`least one menu frame for visually indicating possible
`actions which may be taken while an information frame
`received from the supplier is being displayed on the
`display device. and means for visually overlaying the
`menu frame over the displayed information frame so
`that at least a portion of the displayed information frame
`is displayed simultaneously with the menu frame.
`In preferred embodiments, the processor includes a
`data entry device for enabling the entry of data into the
`apparatus, including commands to cause the processor
`to selectively either overlay the menu over the dis-
`played frame, or to display the menu without any un-
`derlying display of any portion of the previously dis-
`played information frame; the possible actions include
`actions to be taken With respect to the underlying infor~
`mation frame: and one action is the storage of the under-
`lying displayed information frame.
`The overlay enables the user to observe at least part
`of the current frame while acting on a particular menu.
`In another aspect, the invention features apparatus
`for obtaining access via is switched communications
`network to a central supplier of frames of digital infor»
