Problems solved by technology

Therefore, there are following problems in the prior art: 1) when the user uses the TV receiver to watch the DVD video signal, he must first distinguish the input terminal of the receiver, which brings certain troubles to the user
2) Two receiving terminals need to be designed outside the TV receiver, and two independent circuits need to be designed inside to process different input signals respectively, which increases the cost of the TV

Abstract

The invention relates to an input channel and method for progressive and interleaved color difference component signals (i.e. YPbPr / YCbCr) in TV, proposing a progressive / interleaved video signals shared input channel and method, including the following steps: e inputting video signals to a TV receiver from YPbPr / YCbCr input terminals; judging the form of the input video signals is a progressive / interleaved form of video signals; according to the judged result, controlling on or off of YPbPr or YCbCr channel to make the signals pass through corresponding input signal processing circuits, and finally sending them into video processing circuits for further processing. By automatic identification with the TV receiver, for different input video signals YPbPr or YCbCr, the invention only needs a channel to be able to implement watching component video signals, thus reducing the cost, simple in the circuit and compact and convenient to use.

Description

【Technical Field】 [0001] The present invention relates to input channels and methods for progressive and interlaced video signals on video equipment, in particular to input channels and methods for progressive and interlaced color difference component signals (ie YPbPr / YCbCr) in high-definition televisions. 【Background technique】 [0002] In the existing television technology, when watching progressive or interlaced video signals (such as progressive DVD or interlaced DVD), there are usually two input terminals on the television receiver: one progressive input terminal YPbPr, and one interlaced input terminal YCbCr. When using, the user needs to distinguish the format of the input signal and choose different input terminals for different input signals. When the receiver receives different signals, it divides and processes them. The usual processing method is that the input signal of the progressive video signal YPbPr is not digitally processed, and is directly sent to the video a...
