Does a digital TV have a built in antenna or tuner that will pick up over the air signals without an outdoor antenna?

I have not seen any digital TVs with a built in antenna. Depending on where you live you could use a simple "rabbit ears" setup or even one with a built in amplifier if you're a bit far from the stations.

What is data compression?
This is a process which reduces the data rate or file size of digital audio signals. For processes which reduce the dynamic range (without changing the amount of digital data) of audio signals,

Can RF signal travel in air medium without antenna?
No, RF signals require an antenna to effectively transmit through air. The antenna is needed to convert the electrical signals into electromagnetic waves that can travel through the air medium and be received by a distant receiver. Without an antenna, the transmission and reception of RF signals would be very limited.
Is electricity needed ta make an external antenna work?
No, an external antenna can work without electricity. It simply picks up radio frequency signals from the air and sends them to the device it is connected to. The device, such as a TV or radio, uses its own power to process and display the signals.
How can you receive digital TV without cable service?
Put up your own Antenna if you have a HDTV or subscribe to a Satellite service.
How can one watch TV for free without cable?
It depends.... 1. Buy an digital tv (Sdtv or Hdtv) plus an antenna. 2. Analog tv (if you have an older tv), buy a digital to analog converter box plus an antenna. 3. Analog tv and antenna connected to digital DVD or digital VCR.
Does a digital signal travel farther than an analog signal?
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
Is a computer an analog device?
The majority of modern computing devices are digital. That means they work by using many on and off type electrical signals. Analog computers work by using vary ranges of constantly-changing signals in real-time without converting them to digital sequences first.
Can a satellite dish be put in an attic like a broadcast antenna?
No, not really. The satellite signals are much weaker than broadcast signals and they will not make it through solid objects such as a roof. You can get the antenna installed completely free if you shop around, and federal law allows you to put the antenna up, invalidating most local ordinances and covenants restricting them. If you are a renter, you can't make a permanent modification to the property (like drilling holes for the antenna) without permission of the owner. Renters have had some success positioning the antenna in a window with a clear view of the southern sky but that is only for the desperate.
Do TVs work without cable?
Yes, an HD television will operate without an HD cable box. Many will now receive HD signals using a built in tuner and will receive SD signals using the tuner as well. If an HD television is purchased before an upgrade to an HD cable box, the television will accept SD signals from the existing cable box. The quality will still be SD - there is no increase in the resolution just because the television is HD. When an HD box is obtained, the television will be ready to display HD signals.
What are loopbacks?
Loopback is the process of routing digital and electronic signals back to their origin without any changes. It is a way of testing transportation and transmission.
Is an HDMI splitter compatible with Digital Audio?
HDMI splitter is compatible with Digital Audio. HDMI cables and splitters are carrying audio and video signals without any data loss or downgrading quality.
