Benefits of technology
The present invention provides a method, program guide method, and program guide apparatus for acquiring useful program guide information and guiding users through the program guide. This is achieved by scanning accessible channels while a received program is not displayed and displaying a program list based on the stored program guide information. The program guide information can include program guide information of channels tuned before a program guide command is executed, and the apparatus can search for accessible channels in a background operation while the program list is referred to. The technical effects of this invention include improved user experience and more efficient program guide navigation.
Problems solved by technology
However, in a digital multichannel broadcast, tens to hundreds of channels are provided, so that a total number of the selections available to viewers becomes larger and simultaneously program selection is significantly complicated.
That is, since the EPG information of a corresponding channel is transmitted per channel, it is difficult to obtain the EPG information of all channels capable-of being accessed.

Embodiment Construction
[0025] Channel numbers, channel names, program names schedules, etc., generally transmitted as data are displayed on a TV screen as a program list having a time axis and a channel axis by EPG software of a receiver. A user can perform operations such as tuning or programming in the program list by manipulating a cursor.
[0026]FIG. 1 is a block diagram showing the configuration of a conventional digital multichannel TV (hereinafter, called “DTV”) receiver (which is also used in the present invention, as explained with reference to FIG. 2). In FIG. 1, a tuner 102 tunes a radio frequency (RF) channel from received broadcast signals via an antenna 100 under the control of a microprocessor 124. The tuner 102 outputs an intermediate frequency (IF) signal of the tuned channel, and an IF module 104 outputs a baseband signal of the tuned channel to a channel decoder 106.
[0027] The channel decoder 106 channel-decodes the baseband signal received from the IF module 104 and reproduces data bit...

A method acquires program guide information in an image signal receiver, and program guide method and apparatus using the same. In the program guide apparatus, information immediately required by a user is obtained first, and information of less preferential channels is obtained next, thus presenting a smooth interface to the user. The method of acquiring program guide information for channels includes acquiring the program guide information for each channel by scanning accessible channels while a received program is not displayed. The program guide apparatus includes a tuner tuning a channel, a program guide information detector, a memory, a key input, a microprocessor, and a character signal generator.
Description
CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a divisional application of application Ser. No. 09 / 163,977, filed Sep. 30, 1998 which is now pending. This application claims the benefit of Korean Application No. 98-36628, filed Sep. 5, 1998, in the Korean Industrial Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a method of acquiring program guide information in an image signal receiving apparatus, and to a method and apparatus for guiding a program using the same. [0004] 2. Description of the Related Art [0005] Generally, program information of a conventional analog TV broadcast is supplied to publications such-as newspapers, TVs, magazines, etc. However, in a digital multichannel broadcast, tens to hundreds of channels are provided, so that a total number of the selections available to viewers becomes larger and simultaneously progra...
