A

Advanced Television Systems Committee

43
Q

ATSC transmission standard employs what

A

modulation technique called 8-VSB

44
Q

one primary requirement of the DT transmission

A

fit within same 6 MHz of spectrum once occupied by an analog NTSC channel.

45
Q

DTV is not necessarily what

A

HDTV. it can stream SD signals in one 6 MHz wide channel

46
Q

this operates in two frequency ranges

A

Full-service television stations

47
Q

VHF

A

very high frequency

48
Q

range of channels 2-13

A

VHF

49
Q

UHF

A

ultra high frequency

50
Q

range of channels 14-51

A

UHF

51
Q

each television channels occupies how much of the spectrum

A

6 MHz

52
Q

these channels are referred to as the core spectrum

A

Channels 2-51

53
Q

television stations send their programs this way

A

Radio Frequency (RF) form of energy

54
Q

RF is generated by this

A

the transmitter and carried to the antenna by a transmission line

55
Q

this radiates from the antenna and travels at the speed of light

A

RF

56
Q

RF is measured in

A

watts

57
Q

RF measurement is referred to as

A

effective radiated power (ERP)

58
Q

transmitter power output (TPO) is not the same as

A

effective radiated power (ERP)

59
Q

distance of tv RF depends on

A

frequency, ERP, height of antenna above ground

60
Q

this signal requires more than an VHF

A

UHF

61
Q

what happens when trouble occurs in the transmitter or antenna

A

causes reflected power known as voltage standing wave ratio (VSWR)

62
Q

the displayed channel number is based on

A

original analog channel number

63
Q

the digital transmitter and the digital receiver together form what

A

19.39 Mbps- one-way modem

64
Q

The ATSC standard allows for how many video formats

A

36 video formats

65
Q

what 2 scanning methods are used

A

interlaced, progressive

66
Q

what is the format for SDTV

A

30 frames of video each second.

67
Q

what is the aspect ratio

A

proportion between the width and height of the image displayed on the tv screen

68
Q

SD aspect ratio

A

4:3

69

HD aspect ratio

A

16:9

70
Q

letter I and P mean

A

interlaced scanning and sequentially progressive scanning

71
Q

A

720P

72
Q

most common SD picture formats

A

480I

73
Q

these numbers refer to the horizontal scanning lines in the picture

A

480, 720, 1080

74
Q

contain 704 pixels

A

each 480 lines in SD

75
Q

contain 1280 pixels

A

each 720 lines of HD

76
Q

contain 1920 pixels

A

each 1080 lines of HD

77
Q

tv signal transported between equipment using

A

interface standard known as asynchronous serial interface (ASI)

78
Q

before the signal is applied to the transmitter exciter, it is converted to

A

synchronous serial interface (SSI) known as SMPTE 310M

79
Q

the transmitter exciter converts the SSI to

A

ATSC 8-VSB RF/transmission standard

80
Q

the 8-VSB should have a signal-to-noise ratio (SNR) of

A

at least 27 db.

81
Q

Dolby AC-3 system allows up to how many audio channels

A

5.1 channels per bit stream

82
