    Default Differences between the Releases

    Follow us on Social Media





    SDTV

    Standard-definition television (or SDTV) refers to television systems that have a resolution that meets standards but not considered either Enhanced-definition television(EDTV) or High-definition television(HDTV). The term is usually used in reference to digital television, in particular when broadcasting at the same (or similar) resolution as analog systems. In the USA, SDTV refers to digital television broadcast in 4:3 aspect ratio, the same aspect ratio as NTSC signals. When a television set is labeled "SDTV", this means that the set includes an ATSC tuner, but scans its picture in the same 480i pattern used in NTSC.

    PDTV

    PDTV is an abbreviation short for Pure Digital Television. Often seen as part of the filename of TV shows shared through P2P and the Scene FTP systems on the Internet. In this case, PDTV refers not to container, bitrate or dimensions of the video, but the digital nature of the capture source. Non Scene European rippers often use the label DVBRip or DVB-rip to specify a purely digital rip of a Digital Video Broadcast (DVB), however all Scene groups use standardized labeling.

    HDTV

    High-Definition Television (or HDTV) is a digital television broadcasting system with higher resolution than traditional television systems (standard-definition TV, or SDTV). HDTV is digitally broadcast; the earliest implementations used analog broadcasting, but today digital television (DTV) signals are used, requiring less bandwidth due to digital video compression.

    576p

    576p is the shorthand name for a video display resolution. The p stands for progressive scan, i.e. non-interlaced, the 576 for a vertical resolution of 576 lines, usually with a horizontal resolution of 720 or 704 pixels. The frame rate can be given explicitly after the letter.

    Image Example: http://i30.tinypic.com/20sf5gk.png


    720p

    720p is the shorthand name for a category of HDTV video modes. The number 720 stands for the 720 horizontal scan lines of display resolution (also known as 720 pixels of vertical resolution), while the letter p stands for progressive scan or non-interlaced. When broadcast at 60 frames per second, 720p features the highest temporal (motion) resolution possible under the ATSC standard. Progressive scanning reduces the need to prevent flicker by filtering out fine details, so spatial resolution (sharpness) is much closer to 1080i than the number of scan lines would suggest.

    1080p

    1080p is the shorthand name for a category of HDTV video modes. The number "1080" represents 1,080 lines of vertical resolution (1080 horizontal scan lines), while the letter p stands for progressive scan (meaning the image is not interlaced). 1080p can be referred to as full HD or full high definition although 1080i is also "Full HD" (1920x1080 pixels). The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 19201080, or 2,073,600 pixels in total. The frame rate in hertz can be either implied by the context or specified after the letter p (or i), such as 1080p30, meaning 30 Hz.

    1080i and 1080p are both High Definition display formats for HDTVs. 1080i and 1080p signals actually contain the same information. Both 1080i and 1080p represent a 1920x1080 pixel resolution (1,920 pixels across the screen by 1,080 pixels down the screen). The difference between 1080i and 1080p is in the way the signal is sent from a source component or displayed on an HDTV screen.

    In 1080i each frame of video is sent or displayed in alternative fields. The fields in 1080i are composed of 540 rows of pixels or lines of pixels running from the top to the bottom of the screen, with the odd fields displayed first and the even fields displayed second. Together, both fields create a full frame, made up of all 1,080 pixel rows or lines, every 30th of a second.

    In 1080p, each frame of video is sent or displayed progressively. This means that both the odd and even fields (all 1,080 pixel rows or pixel lines) that make up the full frame are displayed together. This results in a smoother looking image, with less motion artifacts and jagged edges.

    1080i is better if you want to save the space on your HDD. While you play the video turn on deinterlace mode.

    1080p is best if you don't care about space however you can have 1080p in the size of 1080i if you use best compression tool and settings to do it.

    (I never use or download any of the i videos, p is always better as it contains the whole image (1080 pixels) in all the frames. )
