Video Connections Basic Information
Composite: Oldest common video connection usually made up of 3 plugs on each end (1 Video, 2 Audio)
S-Video: 4 Pin connector with a better picture then composite connection.
Component Video: 3 plugs which carries 3 video signals with better picture then S-Video or Composite.
DVI: (Digital Video Interface) Mostly found on PC's.
IEEE 1394: (Fire Wire) connection used on PC's and video equipment for transferring Video.
HDMI: (High-Definition Multimedia Interface) The standard for HD has Video & Audio signals using 29 pins. Great with Blu-ray Disc and HD DVD.
Aspect Ratio (Old TV's 4:3 aspect ratio and HDTV 16:9 aspect ratio )
Aspect ratios are mathematically expressed as x:y (pronounced "x-to-y") adding horizontal mattes
(top & bottom black bars or letterboxing) or vertical mattes (pillarboxing) retains the original format's aspect ratio.
FSP (Frames Per Second) 24 FPS is the Film industry standard. Camcorders and HDV Recorders (High
Definition Video) can film in either 30 FPS or 60 FPS with 60 FPS having a slight advantage when filming fast motion and with slow motion editing.
Bit Rate or Bits Per Second (bps) kilobits per second (Kbps), or megabits per second (Mbps) describes the rate at which bits are transferred from one location to another over a period of time. Video and Audio Bit Rate describes the quality of the Video and Audio file with a higher number bit rate being of higher quality but slower when downloading.
Codec 'coder-decoder' Used to describe Video or Audio data that has been converted or compressed by a Computer software program used for Converting Digital or Analog data (Video & Audio) to a specific output or compression needed for encoding or decoding a digital data stream or signal to be viewed.
MPEG 4 Video Compression. (MPEG stands for Moving Picture Experts Group) This is what most of those pocket sized video players use. Though they say its True 1080 HD it is really compressed High Definition Video. You need to convert MPEG4 in order to have total editing capabilities with most movie editing software. (MPEG Streamclip)
Format: PAL (Phase Alternating Line)
NTSC (National Television System Committee)
SECAM (Sequential Color with Memory)
1080p The 'P' stands for progressive, where the lines are displayed sequentially for a better picture then 1080i)
1080i (the i stands for interlacing) Ultra High Definition Television (wiki)
1080p TV is good if over 42 inches so under 42 inches 720p is fine
Plasma has a wider viewing angle then LCD's (Liquid Crystal Display) and Rear Projection's using DLP (Digital Light Processor) Calibration & Diagnostic Tool for Plasma TV's PixelProtector DVD Edition V2 Plasma Circuit Boards
LCD's are lighter, run cooler & use less energy (look for contrast ratio of 15,000:1 & frame rate of 120Hz with LED's)
A new display technology that is in the works is OLED (Organic light-Emitting Diode) Thinner and uses less energy.
