RCA ppt

1. RCA

2. INTRODUCTION
 RCA-Radio Corporation of America
 Phono connector or cinch connector
 Electrical connector commonly used to carry audio
and video signals

3. composite video  (yellow)
stereo audio (white and red)

4. APPLICATION
 Television
 Cable Receivers
 Satellite
 VCR
 Game Console Systems
 Speakers

5. MAXIMUM LENGTH
 10 to 100 feet

6. DIMENSION TYPE
 DIAMETER::0.354 in
(0.90 cm)
 ANALOG
 BIDIRECTIONAL

7. SPECIFICATIONS
 CABLE  COAXIAL
 PASSBAND  Typically 0-100 MHz

8. ADVANTAGES
 Cheap cables and connectors
 Reliable if not connected/disconnected a lot
 Vibration resistant
 Commonly available
 Small and discrete

9. LIMITATIONS
 Signal connection is made before the ground
connection has been guaranteed  produces a loud
buzz
 each signal requires its own plug
 small wire diameter higher resistance and capacitance
susceptible to higher resistance due to corrosion (use
gold plated connectors) hard to make effective shield
connections during manufacture easily pulled out
(unlocked)

10. ELECTRICAL PROPERTIES
 Voltage level is 2V or 4V or 5V
 Voltage Breakdown is at DC 500V/15sec
 RCA cables are closer to tolerant of 35-50ohms. HD is
considerably higher bandwidth and less tolerant of
cables that aren't 75ohms.
 RCA stereo cables are subject to high levels of
electrical interference but that won't effect a digital
signal.

11. VIDEO QUALITY Resolution is 720 X 480
 copper centre conductors, double or triple shielding,
and high-pressure, gold plated RCA connectors
provides better sound quality.
 provides better colour definition and is compatible
with progressive scan signals.
 all picture information including colour, brightness,
and horizontal and vertical synchronization, is
encoded into a single signal
 capable of carrying up to 1080i video

12. FORMAT OF SIGNAL......
STEREO AUDIO
 AES3 bit stream protocol encoding audio signals

13. FORMAT OF SIGNAL......
COMPOSITE VIDEO
 the luminance (B&W detail) information, chrominance
(colour) information and sync pulses are all combined.
 NTSC, PAL and SECAM
 Both the PAL and the NTSC system use a quadrature
amplitude modulated subcarrier carrying the chrominance
information added to the luminance video signal to form a
composite video baseband signal
 SECAM uses frequency modulation to encode chrominance
information on the sub carrier and instead of transmitting
the red and blue information together, it only sends one of
them at a time, and uses the information about the other
colour from the preceding line
