Embodiment Construction

[0026] A preferred embodiment of a channel changing method in a broadcast recorder according to the present invention will now be described in detail with reference to the accompanying drawings.

[0027] The present invention is applicable to different types of broadcast recorders. For example, the present invention can be applied to a broadcast recorder combining a set-top box and a hard disk recorder. Such as image 3 As shown, the broadcast recorder to which the present invention is applied includes a signal processor 21 , an MPEG decoder 22 , a microcomputer 23 , a memory 24 , an HDD recording system 25 and a hard disk 26 . The broadcast recorder further includes a first tuner 20 and a second tuner 27 .

[0028] The first and second tuners 20 and 27 are respectively controlled by the microcomputer 23 to tune to different broadcast channels. At the user's request, the microcomputer 23 receives a broadcast program by controlling the first and second tuners 20 and 27, the ...

Abstract

A channel switching method in a broadcast recorder integrating a set-top box and a hard disk recorder. At the request of the user, channels tuned to by a secondary tuner (27) are switched and other broadcast programs received therethrough are output, while a broadcast program being received through a primary tuner (20) is recorded on a recording medium (26). If the channel recorded on the medium (26) is identical to the channel to which the user has requested channel switching, a time shift operation is performed to reproduce the stored broadcast program while storing the broadcast program being received through the primary tuner (20). Accordingly, if the user desires to return to a channel providing a desired program when viewing programs of other channels, the user can easily resume viewing the desired program, without missing any part of the desired program, which has been received while the user views the programs of the other channels.

Description

technical field [0001] The present invention relates to a channel changing method in a broadcast recorder, and more particularly, to a channel changing method in a broadcast recorder by which, if a user wishes to return to a channel that provides a desired broadcast program while watching other channel broadcast programs channel, the user can simply continue watching the desired broadcast program again without missing any part of the desired broadcast program that has already been received while the user is watching other channel broadcast programs. Background technique [0002] A broadcast recorder that incorporates a recorder such as a hard disk recorder into a broadcast receiver such as a set-top box and can easily record broadcast programs has been commercialized at present. Such as figure 1 As shown, the broadcast recorder may include a tuner 10 , a signal processor 11 , an MPEG decoder 12 , a microcomputer 13 , a memory 14 , an HDD recording system 15 and a hard disk ...
