ínformation on Digital Tblevision

Information on Digital Television

Digital Television

In April 1997, the Federal Communications Commission (FCC) announced that by 2006, all television broadcasting will be digital. However, television stations are required to continue broadcasting regular TV signals along side the digital signals until

2006. Cable and satellite TV are not affected by the FCC ruling. According to the FCC, digital broadcasting must be available from each of the four major networks in each of the top ten markets, covering 30% of households by May

1999. By the end of 1999, it must be available in the top 30 markets, covering 50% of

households. The FCC has allocated to each of the broadcasters a fixed amount of transmitting “space” for digital programming. At the highest resolution. High Definition (HDTV), one (1) or two (2) programs can be transmitted within this “space.” At lower

resolutions, Standard Definition (SDTV), several programs can be simultaneously transmitted. Broadcasters will choose their own broadcast formats. For example, they may choose to broadcast day programs in SDTV and night sports and movies in

HDTV. Digital Television (DTV) broadcasting will deliver crystal-clear pictures,

approaching the quality of 35mm movies, and compact disc (CD) sound.

HDTV (High Definition Television)

HDTV signal formats are 1080i (interlaced scan) and 720p (progressive scan). HDTV

provides the highest resolution picture and audio in either stereo or 5.1 channel surround sound.

SDTV (Standard Definition Television)

SDTV signal formats are 480p and 480i. SDTV provides lower resolution, yet

presents a very sharp clear picture. Lower resolution allows broadcasters to transmit

multiple programs per channel.

Digital Broadcasting and Cable TV

The FCC has not mandated any standards for cable operators or satellite

broadcasters at the time this manual is printed. Some cable companies have

announced plans to introduce digital cable boxes into their markets. They may

choose, however, to use the digital capability to increase the number of channels

available or to provide data capability, such as high speed modem rather than transmit

HDTV programming.

Contact your local cable provider to determine if digital cable is available and

whether a cable box is needed for converting the signals.

Receiving Digital Broadcasts

Most households will be able to receive a digital broadcast by regular antenna with

VHF/UHF reception capability. However, like regular TV signals, it will depend on

location, terrain and environmental factors. Outdoor or attic antennas will generally be

more effective than a set-top antenna. For cable, check with your local cable provider

to find out if they will carry the DTV signal in your area.

Digital Picture Formats

DTV supports eighteen (18) Advanced Television Systems Committee (ATSC)* display formats, which are variations of the four (4) following formats: 1080i (interlaced), 720p

(progressive), 480p (progressive) and 480i (interlaced). The larger the number, the

higher the resolution of the picture.

Interlaced Scan

For interlaced pictures, the odd number lines (picture information) are scanned, creating field 1, then the even number lines are scanned, creating field 2. The two

fields are interlaced to provide the entire image (one frame). This process takes 1/30*'^ of a second and is invisible to the human eye.

Progressive Scan

For progressive pictures, all lines in an entire frame are scanned sequentially in i/60**^

of a second. With progressive scan, you will generally not see the thin black horizontal

scan lines (Venetian blind effect) associated with an interlaced picture.

Digital Audio

For all HDTV formats, Dolby** Digital surround sound (also commonly referred to as AC-3** or DD 5.1) is the audio standard. AC-3 will provide CD-quality sound. The

system provides 3 separate audio channels for the front speakers (left, center, right), 2

channels for the rear surround sound speakers, plus one channel for subwoofer

sound. You will need an external audio system capable of decoding the AC-3

encoded sound to get the full surround sound effect. Otherwise, it can be connected

directly to your TV or audio system using only the stereo (left/right) audio outputs.

Note: The stereo audio outputs are Dolby Surround compatible. You can connect a Dolby

Information on Digital Television

Surround Pro Logic** decoder (not included) to the stereo audio outputs and receive surround sound.

Information on the Set-Top Box

Panasonic Digital Set-Top Box model TU-DST50

Current Conventional Televisions

Panasonic’s digital set-top box (STB) model TU-DST50 uses a Panasonic-developed single chip which will allow current televisions (with AA/ inputs) to display digitally broadcast programs. The STB, which receives only digital signals, has the ability to convert the digital broadcast into National Television System Committee (NTSC)* signals (480i) that a conventional television can display. The picture and sound quality will be similar to small dish digital satellite systems today. Most conventional televisions will not be able to display HDTV programs in their original format.

DTV-Compatible Televisions

The STB, by using component video connections, will allow DTV-compatible televisions to produce pictures with incredible resolution. Component video consists of three (3) primary color signals: red, green and blue that together convey all necessary picture information. The three (3) component signals have been translated into luminance (Y) and two color difference signals (Pq, Pr), each on a separate wire.

The STB, depending on the capabilities of the DTV-compatible television, will give you the choice of HDTV or SDTV format.

Audio/Visual Features

The STB contains two vital links to the future of TV. The optical Dolby Digital (AC-3) output connection provides the highest quality surround sound when attached to an external AC-3 decoder/receiver. A digital interface connection allows the STB to be attached to a Panasonic digital VHS (D-VHS) VCR.

DTV-Compatible Monitor/Receiver Capability

HDTV-Compatible (1080i/720p)

HDTV-compatible TV models process and display high definition output from the

Panasonic STB as a 1080i or 720p format. When DTV broadcasts are available in your viewing area, your HDTV monitor/receiver will be compatible using the STB. It will display the 16:9 wide screen aspect ratio format.

SDTV-Compatible (480p/480i)

SDTV-compatible TV models process and display standard definition output from the

Panasonic STB as a 480p or 480i format. When DTV broadcasts are available in your

viewing area, your SDTV monitor/receiver will be compatible using the STB. It will

display the incoming SDTV format.

*NTSC is the current television system used in the U.S. It uses analog (non-digital) signals.

Congratulations

Your Panasonic digital set-top box (STB) features state-of-the-art technology for highquality picture and sound with complete audio/video output jacks for your home theater system. DTV signals are displayed in either an interlaced or progressive format, providing a clear, crisp picture. When connected to the STB, your HDTVcompatible monitor/receiver can display high-definition (HDTV) 1080i or 720p format and standard definition (SDTV) 480p or 480i format. Your new STB is designed to give you many years of enjoyment.

Antenna Installation and Orientation

In many areas, an indoor antenna can be used to received DTV signals. Certain conditions, however, may create a situation where an outdoor antenna is required. Tall

buildings, large metal objects (e.g., a water tower) or hills may block the line-of-sight to the TV station and interfere with DTV signal reception. Keep the following in mind when installing and orienting your outdoor antenna. For additional information about antennas, see the Consumer Electronics Manufacturing Association (СЕМА) website at

www.cemacity.org or ask your local dealer.

□ Choose an antenna with directional receiving characteristics such as a Yagi, log periodic, or

reflector antenna. Avoid loop, wire bowtie, rabbit-ear and omni-directional antennas.

□ Use good grade 75 Ohm coax (round) cable to connect the antenna to the STB. Do not use

300 Ohm flat twin-lead cable.

□ Place the antenna away from large metal objects. If using an indoor antenna, remember

that aluminum siding and foil-covered insulation can greatly reduce the signal strength inside your house.

□ Point the antenna in the direction of the TV station. Allow a 4-6 second delay in tuning.

Watch for a program to appear on the TV. If the signal indicator is “NOT FOUND” or if a

program comes and goes, try a slightly different position for the antenna. Slowly raising or lowering the antenna by a few feet may help.

□ Avoid standing in front of the antenna while adjusting its position. Move a few feet to the

rear to avoid changing the signal characteristics.

□ If you are located in an area serviced by two (2) different DTV stations in different directions,

you may need an antenna rotator to receive signals from both stations.

Channel and Program Tuning

Channel and program tuning in digitai television is very different from current conventional television. In DTV, up to six (6) multiple programs can exist within a single 6 MHz channel. These programs behave as subchannels within the single channel. When tuning to a channel, the STB will also tune to a program. Your STB will indicate the channel and program through the on-screen Channel Banner display.

Channel and Program Tuning

The STB allows channel and program selection in the following ways:

□ Direct Tuning (0-9 keys) - Tunes directly to a channel or program. □ Channel Up/Down Tuning (A or ▼ buttons) - Tunes to the next or previous available

channel or program.

□ Next Program Tuning (PROG button) - Tunes to the next program within a single 6 MHz

channel.

n Rapid Tuning (R-TUNE button) - Switches between the last two remembered channels or

programs.

Next Program Tuning

The PROG button on the remote control allows you to select programs within a single 6 MHz channel. Each time the PROG button is pressed, the STB will move to the next

available program within the channel.

Note: Only programs within the current 6 MHz channel can be selected using the PROG

button. If only one (1) program appears, it indicates only one (1) program Is available.
