You can refer to the following pictures for the image before and after DeInterlacing :
Both the traditional CRT TV and CRT monitor are interlace devices.
Both the LCD TV and LCD monitor are non-interlace devices.
You will see "Ghosting" image or "Sticking" image when display the fast motion interlace video on the non-interlace device.
The "Deinterlacing" technology is developing to improve the display quality.
What is Deinterlacing? Facts, solutions, examples.

Example 3:
Original Interlace 
Use Blend Deinterlacing method

Use the GSpot v2.70a to verify the recorded MPEG2 file is Interlace or Progressive :
http://www.headbands.com/gspot/v26x/GSpot270a.zip
http://www.headbands.com/gspot/v26x/index.htm
http://www.headbands.com/gspot/mpeg_int … cators.htm
[I/L] -> Interlace
[PROG] -> Progressive
These two indicators indicate "interlaced" or "progressive scan" (non-interlaced), respectively. Inclusion of the pair is a convenience, albeit a bit redundant, as the two are complementary: any time one is active the other is not. They may, however, both be grayed; as with the other indicators, this simply means the information is not available.
[CBR] : Constant BitRate
[VBR] : Variable BitRate
For examples,
480i MPEG2 (VBR, 4:3) :
576i MPEG2 (VBR, 4:3) :
576i MPEG2 (VBR, 16:9) :
576p MPEG2 (CBR, 16:9):
720p MPEG2 (CBR, 16:9) :
1080i MPEG2 (CBR, 16:9):
1080i MPEG2 (VBR, 16:9):
You can use the VLC Media Player to play the Interlace (480i/576i/1080i) MPEG2 file.
And choice the different DeInterlace method in the VLC Media Player to see
the result of DeInterlacing :

Many softwares have their own DeInterlace method.
For example, it is called "Smart Video DeInterlacing" in the CyberLink PowerDVD 7 series :
Q:Can the software MPEG2 encoder support both Interlace and Progressive mode ?
A:Yes. CyberLink MPEG2 encoder can do that.
CyberLink MPEG2 encoder’s encode modes :
ENC_MODE_FRAME: output video in progressive frame mode
ENC_MODE_SINGLEIFRAME: output video single I-frame mode
ENC_MODE_FIELD_TOP: output video is field encoding, top field first
ENC_MODE_FIELD_BOTTOM: output video is field encoding, bottom field first
ENC_MODE_FIELD_TOPTOBOTTOM: input video is top field first, output video is shifted to bottom field first
ENC_MODE_FIELD_BOTTOMTOTOP: input video is bottom field first, output video is shifted to top field first
ENC_MODE_INTERLACE_FIELD_TOP: for top field first interlace video encoding
ENC_MODE_INTERLACE_FIELD_BOTTOM: for bottom field first interlace video encoding
ENC_MODE_FAKE_FIELD_TOPTOBOTTOM: input video is top field first, output video is shifted to bottom field first
ENC_MODE_FAKE_FIELD_BOTTOMTPTOP: input video is bottom field first, output video is shifted to top field first
Q:Can the Conexant hardware MPEG2 encoder CX23416/CX23417 support both Interlace and Progressive mode ?
A:No. The Progressive mode is not supported in the current firmware of Conexant CX23416/CX23417.
Q:Can the "video decoder" implement the DeInterlacing ?
A:Many popular video decoders do not implement the DeInterlacing,
such as BT878/9, CX23880/1/2/3, CX25843/2/1, CX23885, CX23418, SAA7115/4/3, SAA7130/1/2/3/4, SAA7136, SAA7162, TI5150, ..., etc.
