KR970057451A - Sub-audio channel search device for playback of sub-picture on TV with PIP function - Google Patents

Abstract

According to the present invention, when the sub picture reproduced through the PIP function reproduces an external video signal according to the AV mode, the broadcast contents are sequentially searched through all channels of the television broadcast through the sub-audio allocated to the sub picture. It provides a sub-audio channel search device when playing an external video sub-screen of a television equipped with a PIP function.

Accordingly, the present invention reproduces the external video / audio signal from the external video / audio input terminal (V, A) according to the execution of the AV mode through the sub picture and the sub audio according to the PIP function. Function setting means (2) for setting the channel search function of all channels, memory means (4) storing channel tuning data of all selectable channels, and external video / audio through sub-pictures and sub-audios according to the PIP function. In the state of reproducing the signal, the control means (6) for controlling the entire channel to be searched through the sub-voice according to the setting of the channel search function by the function setting means (2), and the predetermined channel for reproducing the main screen. The external video / audio input terminal (V, A) according to the setting of the AV mode of the first and second tuning means (8, 10, 12, 14) for sequentially tuning all channels according to the channel search function together with the tuning. External video / audio signal can be played through External mode switch means 16 switched to switch, video mode switch means 18 switched to assign video signals for the main / sub picture according to the PIP function, and the channel for the main audio in the AV mode setting. A voice mode switch means 20 for passing the voice signal of the voice signal to be reproducible and switching the voice signal of the channel sequentially searched for the sub voice according to the channel search function through the sub voice to enable the sub voice reproducibility; And display signal processing means 30 for generating display information for screen display of channels sequentially searched according to the channel search function through the sub-voice.
