Definitions

  • the present invention relates to control systems for electronic devices such as televisions and personal computers (PCs) and, particularly, to a control system having a user interface system that provides information to a user and simplifies use of the device.
  • a user interface is an Electronic Program Guide (EPG) in a television system.
  • EPG Electronic Program Guide
  • An EPG is an interactive, on-screen display feature that displays information analogous to TV listings found in local newspapers or other print media.
  • an EPG also includes information necessary for collating and decoding programs.
  • An EPG provides information about each program within the time frames covered by the EPG, which typically ranges from the most previous half-hour up through the next seven days.
  • the information contained in an EPG may include programming characteristics such as channel number, program title, start time, end time, elapsed time, time remaining, rating (if applicable), topic, theme, and a brief description of the program's content.
  • EPGs are usually arranged in a two-dimensional table or grid format with time on one axis and channel numbers on the other axis.
  • EPGs allow viewers to obtain and view programming information in a variety of formats including current channel, partial list of channels, and all channels. Further, EPG features may include the ability to highlight individual cells of the grid containing program information. Once highlighted the viewer can perform functions pertaining to the selected program. For example, the viewer could instantly switch to that program if it is currently being aired. Viewers could also program one touch video cassette recording (VCR) or the like if the television is properly configured and connected to a recording device.
  • VCR video cassette recording
  • US Pat. No. 5,515,106 issued to Chaney et al., and assigned to the same assignee of the present invention, describes in detail an exemplary embodiment including data packet structure necessary to implement an exemplary program guide system.
  • the exemplary data packet structure is designed so that both the channel information (e.g., channel name, call letters, channel number, type, etc.) and the program description information (e.g., title, rating, star, etc.) relating to a program may be transmitted from a program guide database provider to a receiving apparatus efficiently.
  • channel information e.g., channel name, call letters, channel number, type, etc.
  • program description information e.g., title, rating, star, etc.
  • EPGs User interfaces such as EPGs are applicable to both analog and digital television systems as well as to other electronic devices such as personal computers.
  • electronic devices become increasingly complex with a multitude of features, the need for a robust and easy-to-use user interface can not be emphasized enough.
  • separate electronic systems having respective interfaces for controlling features of each system are now being combined into a single system requiring a single user interface.
  • PCTV which includes features of both a personal computer and a television.
  • the user interface system for such a device must provide both clear communication of computer and television related information and provide for simple control of both computer, including Internet use, and television related features.
  • the inventor has recognized limitations in current EPGs.
  • One such limitation is that the current EPGs only indicate the current time in an unrelated graphical or textual format, e.g. 5:55 PM typically in one corner of the display, along with a graphical representation of a selective two-hour time frame.
  • the time frame range usually demarcated by a box or outlined in a particular manner, is preset to display from between the previous one-half hour and the next seven days. Since the EPG typically begins by displaying historical information from the previous one-half hour and is only updated every 30 minutes, a user can not simply determine how much time remains in a particular program.
  • the current EPG display may be from either the beginning or the end of the 30-minute update period.
  • the present time is not displayed graphically on the EPG relative to the graphical representation of a program along its graphic time grid, thereby preventing the user to intuitively know the amount of time left on a desired program.
  • the user is relegated to viewing the current time as displayed in one corner of the EPG and then the end time of a subject program.
  • the present invention teaches a user selectable graphical display for exhibiting the current time in an Electronic Program Guide (EPG) by varying the color, shading or the like of a portion of the EPG representing a program from the start of that program to the end of that program.
  • EPG Electronic Program Guide
  • the color, shading or the like may include the start of a previous time period e.g., one-half hour, through and including the present time. The user can now easily determine how much time is left in a given program by assessing the location of the proximal edge of the shaded display of the start of the program with respect to the edge, which represents the completion of such program.
  • the update rate of the graphical representation of the current time can be set to any time, for example, one, three, or six-minute intervals.
  • the user does not have to first read the current time, typically depicted in a textual format in one corner of the display, and then interpret the graphical EPG display to determine the length of time remaining on a given program.
  • tick mark for example an inverted triangle
  • a vertical "hash mark” for example, a dotted or dashed line, may also be employed either with or without the subject tick mark to also graphically indicate the present time.

If however, the Current Time is within the Current Screen Time Boundaries 58, then the Current Time is converted into a horizontal (or vertical) Screen Pixel Position using the same transfer function used for Programs or Events in the Program Guide display 62. After conversion 62, the Screen Pixel Position is used to draw a graphical representation of Current Time in the correct location or program box on the grid of the Program Guide 64. Thereafter, the On-Screen Program Guide is drawn 60 on display 30 and the program continues as normal 66.
  • Figure 10 is an exemplary software listing designed to implement the functions shown in flowchart 52 of Figure 9.

Thereafter, source code 70 generates and places a graphical representation of current time into the EPG channel/program versus time grid.

  • a Master Program Guide is transmitted on all transponders; other guides may be transmitted on other transponders and are mapped from the master program guide.
  • the master program guide contains a listing of all current programming, while the other guides may be used for future programming.

Abstract

La présente invention concerne un système de guide électronique d'émissions de télévision capable d'afficher un guide électronique d'émissions de télévision (EPG) comportant une représentation graphique de l'heure courante dans une zone 'durée' d'une émission de façon à permettre au téléspectateur d'évaluer intuitivement l'heure courante par rapport à une émission donnée, et ainsi d'évaluer le temps restant à courir pour cette émission. La représentation graphique de l'heure peut prendre la forme, soit d'un changement de couleur ou d'une ombre portée dans la zone 'durée' de l'émission venant contraster sur un fond, soit d'un changement de couleur du fond d'une échelle de temps graphique adjacente de la zone 'durée' de l'émission, soit encore d'un hachurage ou de barrettes. Une telle représentation graphique de l'heure courante à l'intérieur des zones des émissions, ainsi que pour les programmes des émissions d'une chaîne permet de conserver une relation avec une échelle de temps incrémentielle représentant la longueur des émissions actuellement affichées à l'écran.
