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
The invention relates to the method for handling output signal in optical disc apparatus according to the television scanning mode, is to carry out signal processing and output at the scan mode of television set.
(2) background technology
Generally speaking, optical disc apparatus will be recorded in DVD, and the data on the CDs such as HD-DVD are play, and also obtain the development that leaps along with its performance of development of video and voice data compress technique and transmission technology.
Video or audio signal that above-mentioned optical disc apparatus is play are exported by display unit such as television sets.The picture signal scan mode of above-mentioned TV set image has interlacing scan and lines by line scan two kinds.Interlacing scan is to be basis with the vertical synchronizing signal, has scanned odd field a kind of scan mode of scanning even field between odd field more later on.Progressive scan mode is equally according to vertical synchronizing signal, but is with odd field and even field a kind of scan mode of scanning in order simultaneously.
Therefore, if the scan mode of television set support is an interlace mode, and be the signal of handling with progressive scan mode from optical disc apparatus input, perhaps the scan mode of television set support be progressive scan mode and from optical disc apparatus input be the signal of handling with interlace mode, vertical synchronizing signal will contradict each other and make the signal that reads input from optical disc apparatus normally to be shown on the picture so.
(3) summary of the invention
Therefore the present invention carries out in order to address the above problem just.Purpose of the present invention be exactly to provide a kind of in optical disc apparatus the method according to the different disposal output signal of television scanning mode, just can come processing signals according to the scan mode of television set support by this method, no matter the television set support is the display frame normally of which kind of scan mode.
Another object of the present invention is to provide a kind of method of the different choice television scanning mode according to received signal, by this method no matter the signal processing mode in the optical disc apparatus be interlacing scan or line by line scan that vision signal can both be play normally by television set.
To achieve these goals, the method for handling output signal in optical disc apparatus according to the television scanning mode of the present invention was characterized in comprising with the next stage: the phase I, determine the scan mode that television set is supported according to the vision signal of television set output; Second stage is carried out Video signal processing and output according to the scan mode difference of determining.
In addition, in order to realize above-mentioned another purpose, the method of the different choice television scanning mode according to received signal of the present invention, be characterized in comprising with the next stage: the phase I, come the confirmation signal processing to be by interlace mode or to pass through progressive scan mode according to the vision signal of CD output; Second stage according to confirmed signal processing mode, determines the scan mode of above-mentioned vision signal and plays.
For further specifying above-mentioned purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.
