1 Course Presentation Multimedia Systems Video I (Basics of Analog and Digital Video) Mahdi Amiri November 2015 Sharif University of Technology

2 Video Visual Effect of Motion The visual effect of motion is due to biological phenomenons. 1. Persistence of vision An object seen by the human eye remains mapped on the eye s retina for a brief time after viewing (approximately 25 ms) 2. Phi phenomenon When two light sources are close by and they are illuminated in quick succession, what we see is not two lights but a single light moving between the two points (apparent movement or perceiving movement) Due to the above two phenomena of our vision system, a discrete sequence of individual pictures can be perceived as a continuous sequence. Page 1

3 Video Definition A sequence of still images representing scenes in motion. Frame Rate Number of still images/pictures per unit time Frames / Second (fps) Frame rate of video ranges from 6to 8 fps for old mechanical cameras to 120or more fps for new professional cameras. The minimum frame rate to achieve illusion of a movingimage is 15fps. Frame 0 Frame N-1 Time Page 2

4 Video Representation Video Display, CRT In conventional TV sets or monitors, the video signal is displayed using a CRT (Cathode Ray Tube). An electron beam sweeps the screen from top to bottom beam carrying the corresponding pattern information, such as intensity in a viewed scene. Video can be interlacedor progressive( Will be discussed later in this lecture ). Page 3

5 Video Representation Millions of LCD shutters en.wikipedia.org/wiki/lcd_television Video Display, LCD Liquid-crystal-display televisions (LCD TV) produce a black and colored image by selectively filtering a white light. The light is typically provided by a series of cold cathode fluorescent lamps (CCFLs) at the back of the screen, although some displays use white or colored LEDs instead. Millions of individual LCD shutters, arranged in a grid, open and close to allow a metered amount of the white light through. Each shutter is paired with a colored filter to remove all but the red, green or blue (RGB) portion of the light from the original white source. If we apply an electric charge to liquid crystal molecules, they untwist. When they straighten out, they change the angle of the light passing through them so that it no longer matches the angle of the top polarizing filter. Consequently, no light can pass through that area of the LCD, which makes that area darker than the surrounding areas. electronics.howstuffworks.com/lcd2.htm Page 4

6 Video Display Progressive Scanning Flicker free at around 50 frames per second (fps) Flickeris a visible fading between cycles displayed on video displays, especially the refresh interval on cathode ray tube (CRT) based computer screens. Flicker and Bandwidth Page 5

7 Video Display Interlaced Scanning Flicker free at around 25 frames per second (fps) First the solid (odd) lines are traced, P to Q, then R to S, etc., ending at T; then the even Field starts at U and ends at V. The jump from Q to R, etc. is called the horizontal retrace, during which the electronic beam in the CRT is blank. The jump from T to U or V to P is called the vertical retrace. Electronic signal for one NTSC scan line. Page 6

8 Video Display Odd and Even Fields Odd Field A Video Frame Because of interlacing, the odd and even lines are displaced in time from each other -generally not noticeable except when very fast action is taking place on screen, when blurring may occur. Initiallythe odd-numbered lines are scanned and thenthe process is repeated for even-numbered lines -this time starting at the second row. Even Field Difference of Fields Page 7

9 Video Display Page 8 Deinterlacing Deinterlacingis the process of converting interlaced video, such as common analog television signals into a non-interlaced form. Method 1: Capturing one field and combining it with the next field Problem: "combing" effect Method 2: Line doubler The most basic and literal way to double lines is to repeat each scanline, though the results of this are generally very crude. Most line doublers use digital interpolation to recreate the missing lines in an interlaced signal, and the resulting quality depends on the technique used. Generally a line doublerwill only interpolate within a single field, rather than merging information from adjacent fields, to preserve the smoothness of motion, resulting in a frame rate equal to the field rate. When interlaced video is watched on a progressive monitor with very poor deinterlacing, it exhibits combing when there is movement between two fields of one frame. Serrated image

10 Analog Broadcast TV Systems NTSC NTSC (National Television System Committee) Mostly used in North America and Japan Aspect Ratio: 4:3 525 scan lines at 30 fps Interlaced scanning (262.5 lines/field) Color Space: YIQ Page 9

11 Analog Broadcast TV Systems YIQ Color Space In the YIQ color system, the Iaxis runs from cyan to orange, and the Qaxis runs from green to violet. Eye is most sensitive to Y, next to I, next to Q. Bandwidth allocation for color components 4 MHz is allocated to Y, 1.5 MHz to I, 0.6 MHz to Q. When compared to PAL in particular, NTSC color accuracy and consistency is sometimes considered inferior, leading to video professionals and television engineers jokingly referring to NTSC as Never The Same Color, Never Twice the Same Color, or No True Skin Colors,[16] while for the more expensive PAL system it was necessary to Pay for Additional Luxury. Page 10

12 Analog Broadcast TV Systems PAL PAL (Phase Alternating Line) Mostly used in Western Europe, China and India Aspect Ratio: 4:3 625 scan lines at 25 fps Interlaced scanning (312.5 lines/field) Color Space: YUV 5.5 MHz is allocated to Y, 1.8 MHz each to U and V. Page 11

13 Analog Broadcast TV Systems NTSC Video Signal The horizontal sweep frequency is ,750 lines/sec, so that each line is swept out in 1/15,750 sec 63.5μsec. Vertical retrace takes place during 20 lines reserved for control information at the beginning of each field. Hence, the number of active video lines per frame is only 485. Similarly, almost 1/6 of the raster at the left side is blanked for horizontal retrace and sync. The nonblanking pixels are called active pixels. NTSC video is an analog signal with no fixed horizontal resolution. Therefore one must decide how many times to sample the signal for display: each sample corresponds to one pixel output.

14 Analog Broadcast TV Systems Modulation of NTSC An NTSC television channel as transmitted occupies a total bandwidth of 6 MHz The actual video signal, which is amplitude-modulated, is transmitted between 500 khz and 5.45 MHz above the lower bound of the channel. The video carrier is 1.25 MHz above the lower bound of the channel. Like most AM signals, the video carrier generates two sidebands, one above the carrier and one below. The sidebands are each 4.2 MHz wide. The entire upper sideband is transmitted, but only 1.25 MHz of the lower sideband, known as a vestigial sideband, is transmitted. Supplementary Materials The color subcarrier, as noted above, is MHz above the video carrier, and is quadrature-amplitudemodulated with a suppressed carrier. The audio signal is frequency-modulated. Spectrum of a System M television channel with NTSC color. Page 13

15 Analog Broadcast TV Systems Chroma Modulation of NTSC In NTSC, chrominance (C) is encoded using two MHz signals that are 90 degrees out of phase, known as I (in-phase) and Q (quadrature) QAM. These two signals are each amplitude modulated and then added together. Supplementary Materials ( ) = ( ) cos( 2π ) + ( ) sin( 2π ) C t I t ft Q t ft f 0 is the carrier frequency 0 0 Chroma Demodulation of NTSC In the ideal case I(t) is demodulated by multiplying the transmitted signal with a cosine signal. Low-pass filtering ri(t) removes the high frequency terms (containing 4πf0t), leaving only the I(t) term. i i i ( ) = ( ) 2cos( 2πft 0 ) 2 ( ) = 2 ( ) cos ( 2π 0 ) + 2 ( ) sin( 2π 0 ) cos( 2π 0 ) ( ) = ( )( 1+ cos( 4π 0 )) + ( ) sin( 4π 0 ) ( ) = ( ) + ( ) cos( 4π ) + ( ) sin( 4π ) r t C t r t I t ft Q t ft ft r t I t ft Q t ft ri t I t I t ft 0 Q t ft 0 Similarly, Q(t) can be extracted by first multiplying C(t) by 2sin(2πf0t) and then low-pass filtering. Page 14

16 Analog Broadcast TV Systems Modulation of PAL The basics of PAL and the NTSC system are very similar; a quadrature amplitude modulated subcarrier carrying the chrominance information is added to the luminance video signal to form a composite video baseband signal. In order to improve picture quality, chroma signals have alternate signs (e.g., +U and -U) in successive scan lines, hence the name Phase Alternating Line. This facilitates the use of a (line rate) comb filter at the receiver the signals in consecutive lines are averaged so as to cancel the chroma signals (that always carry opposite signs) for separating Y and C (chroma) and obtaining high quality Y signals; Supplementary Materials Spectrum of a System I television channel with PAL color. However, this resulted in a comblike effect known as Hanover bars on larger phase errors. Thus, most receivers now use a chrominance delay line, which stores the received color information on each line of display; an average of the color information from the previous line and the current line is then used to drive the picture tube. Hanover bars Cancellation of Hanover bars through a chroma delay line Page 15

17 Analog Broadcast TV Systems Supplementary Materials SECAM stands for SystèmeElectroniqueCouleurAvec Mémoire, the third major broadcast TV standard. Aspect Ratio: 4:3 625 scan lines at 25 fps, Interlaced scanning SECAM and PAL are very similar. They differ slightly in their color coding scheme: In SECAM, U and V signals are modulated using separate color subcarriers at 4.25 MHz and 4.41 MHz respectively. They are sent in alternate lines, i.e., only one of the U or V signals will be sent on each scan line. Page 16

19 Analog Color Video Composite video wire Signal Protocols Color (chrominance) and luminance signals are mixed into a single carrier wave. Since color and intensity are wrapped into the same signal, some interference between the luminance and chrominance signals is inevitable. Composite video jacks are often grouped with corresponding stereo audio jacks (the composite video jack is usually yellow) Page 18

20 Analog Color Video Signal Protocols S-Video (Separated video, e.g., in S-VHS) wires,one for luminanceand another for composite chrominance signal As a result, there is less crosstalk between the color information and the crucial gray-scale information. A compromise between component analog video and the composite video. A standard 4-pin S-Video cable connector, with each signal pin (3, 4) paired with its own ground pin (1,2) Page 19

21 Analog Color Video Signal Protocols Component video wires Each primary is sent as a separate video signal. The primaries can either be RGB or a luminance-chrominance transformation of them (e.g., YPbPr, YIQ, YUV). Y: Green wire, Pb: Blue wire, Pr: Red wire Best color reproduction Requires more bandwidth and good synchronization of the three components More about signal protocols at YPbPr is analog form of YCbCr VGA: like component video using RGB instead of YPbPr. Page 20

22 Digital Video Advantages Video can be storedon digital devices or in memory, ready to be processed (noise removal, cut and paste, etc.), and integrated to various multimedia applications. Direct access is possible, which makes nonlinear video editing achievable as a simple, rather than a complex, task. Repeated recording does not degrade image quality. Ease of encryption and better tolerance to channel noise. Page 21

23 Digital Video HDTV vs. Conventional TV HDTV has higher resolution or HDTV has a much wider aspect ratio of 16:9instead of 4:3. 16:9 is closer to aspect ratio of the human eye sight HDTV moves toward progressive(non-interlaced) scan. The rationale is that interlacing introduces serrated edges to moving objects and flickers along horizontal edges. Page 22

26 Digital Color Video Signal Protocols SDI(Serial Digital Interface), 1989 Standardized by SMPTE (The Society of Motion Picture and Television Engineers) For standard definition applications the most commonly used bit rates is 270 Mbit/s. 1998: HD-SDI(high-definition SDI), nominal data rate of Gbit/s. 2002: Dual Link HD-SDI, Gbit/s over two wires These bit-rates are sufficient for fps Serial digital interface uses BNC connectors. en.wikipedia.org/wiki/serial_digital_interface Page 25

30 Digital Color Video Note: our focus was to talk about protocols and not connectors. Signal Protocols vs. Connectors e.g. SCART is a connectorfor analog video transmission and can use composite, S-Video and component video signal protocols. VGA connector (DE-15 is a common variant.) Became a nearly ubiquitous analog computer display connector after first being introduced with IBM x86 machines. Older VGA connectors were DE-9 (9-pin). The modern DE-15 connector can carry Display Data Channel to allow the monitor to communicate with the graphics card, and optionally vice versa. SCART: Carries stereophonic sound (analog), along with composite video and/or RGB video. Some devices also support S-Video, which shares the same pins as composite video and RGB. YPBPR is also sometimes supported as a nonstandard extension via the RGB pins. Page 29
