Problems solved by technology

[0004] Therefore, if the scanning method supported by the TV is an interlaced scanning method, and the input from the optical disc device is a signal processed in a progressive scanning method, or the scanning method supported by the TV is a progressive scanning method and the input from the optical disc device is a signal processed in a progressive scanning method. If the signal is processed in an interlaced scanning mode, the vertical synchronization signals will conflict with each other, so that the input signal read from the optical disc device cannot be displayed on the screen normally.

Embodiment Construction

[0016] figure 1 It is a configuration diagram of an optical disc device and a TV set according to a method for processing output signals in the optical disc device according to different scan modes of the TV set according to the first embodiment of the present invention.

[0017] The TV set of the present invention, as shown in the figure, includes the following components: a signal receiving unit 11, which is used to receive and process the signal output by the optical disc device; a signal processing unit 12, which is used to process the signal received by the signal receiving unit 11 to make It is suitable for displaying on the screen; the signal output unit 13 displays the signal processed by the signal processing unit 12 on the screen or feeds it back to the optical disc device.

[0018] The optical disc device of the present invention, as shown in the figure, includes the following components: a signal receiving part 24, used to receive and process the video signal fed b...

Abstract

The invention relates to a method to process output signal according to the scanning method of television in disc device, which has high usable value. It includes the following steps: first, confirming the scanning method that the television supported according to the feedback signal form the television; second, processing video signal and output according to the confirmed scanning method. Thus, whichever the scanning method the television supports, it would be normally to play. No matter the signal process method of the disc device whether is interleaved-scanning or non-interlaced-scanning, the television would play video normally.

Description

(1) Technical field [0001] The present invention relates to a method for processing an output signal in an optical disk device according to the scanning mode of a TV set, and is for signal processing and outputting according to the scanning mode of the TV set. (2) Background technology [0002] Generally, an optical disc device plays data recorded on optical discs such as DVD and HD-DVD, and its performance is rapidly developing with the development of video and audio data compression technology and transmission technology. [0003] The video or audio signal played by the optical disc device is output through a display device such as a television. There are two types of image signal scanning methods for the TV screen: interlaced scanning and progressive scanning. Interlaced scanning is based on the vertical synchronous signal, a scanning method that scans even fields between odd fields after scanning odd fields. The progressive scanning method is also based on the vertical...
