  1. time base correctors
    correct the minor errors found on tape but some video sources are out of sync with the studio
  2. a blimp would be
    non-synchronous or wild video source because it could not have a cable from the sync generator on the ground
  3. Frame synchronizers
    like time base correctors with a larger memory, converts lines of analog video signal into digital and stabilizes them
  4. frame synchronizer gate release signal
    vertical sync instead of horizontal sync. when it gets a vertical sync pulse from the house sync generator the frame synchronizer feeds out a field of video information. only non-synchronous video sources can be locked up and integrated to system. expensive but do everything TBCs can do plus lock up non-synchronous sound
  5. HDTV Production
    technology and equipment used to record and create programming
  6. HDTV broadcasting
    method of sending programming through air (cable or satellite) to homes
  7. HDTV's component system
    uses 8, 10, or 12 bit processing. 720 or 1080 scanning lines of 1920 pixels each line. 16:9 aspect ratio, 4:2:2 encoding ratio, scanned at 60 fields/30 frames interlace, 50 fields/25 frames interlace, 30 frames p or 24 frames p per second
  8. HDTV requires
    60 MHz. 30 MHz for Y 15 for R-Y and 15 for B-Y
  9. the biggest change for HDTV is
    16:9 aspect ratio from 4:3
  10. 1998 Advanced Television Systems Committee
    standards that can be received and displayed on HDTV & SDTV digital TV sets. digital system still uses 6 MHz bandwidth. supports 18 different digital standards, wide screen.
  11. two different HDTV options for ATSC High Definition broadcast standards
    1) 1080p - 1080 scanning lines with 1920 pixels each. 60 fields/30 frames interlace or 30 fields/24 frames progressive 2) 720 p- 720 scanning lines of 1280 pixels per line. 60, 30, or 24 frames of progressive. (p is easier with computers, 24 frames/sec easy with film)
  12. Standard Definition Digital Television
    digitize the standard NTSC video signal and compress it so 4 or more signals can fit into one standard NTSC 6 MHz bandwidth channel. broadcasters can now send out multiple programs on standard TV channel. future-both SDTV & HDTV
