Internet TV Inputs

TV Inputs From Computer Overview

Internet TV Computer Inputs

The following are common TV inputs from your comuputer for us to consider using in setting up your Internet TV.

RCA (Composite Video – Audio-Visual)

This is the most wide spread input on TV’s. However, it is not a digital input and thus lower quality than a HDMI or DVI. This input of A/V (video and audio) and audio is also known as RCA or composite. A/V ports cannot transmist HD video and only stero from the audio input. Even though A/V is old technology, many TV’s have it, so we will use it if there is no HDMI, DVI or Component.

Component Video (YPbPr)

If there is no HDMI, this has good input quality, but is difficult to work well with a PC to TV. It has the (Red-Green-Blue) ports also known as component connections. We will not be able to get you 1080p video via RGB only 1080i and they do not transmit audio. RGB ports are mot that commonly used in most devices. We might use them to connect your PC to your HDTV, but it is not a popular or practical choice.

Cable

All the TV’s will have the analog or digital coaxial cable input. That is where you get your TV programs from via Cable or Antenna. There is virtually no deviation from TV to TV. They are all pretty much to same. All you need is the cable and somewhere to plug it into. However, this is not practical to connect from a Computer to TV.

VGA

Almost all Computers have one of these ports and they are starting to appear on TV’s. It is called a VGA (video graphic array) and also called D-Sub. It is excellent for quickly connecting your PC to your TV. Unfortunately, VGA does not carry audio and the resolution will not reach 1080p.

HDMI

The the HDMI port (High Definition Multimedia Interface.) is the connection of choice. Many newer computers and TVs have this output and input. HDMI is capable of transmitting highest quality 1080p video and up to 8 channels of surround sound audio.Some TV’s come with 2 HDMI ports or more, they either on the back, side or front ot the TV.

DVI

Digital Visual Interface (DVI). This digital interface is primarily used to connect a computer to a computer monitor. However, some newer model TV’s have this input. They are excellent for quickly connecting your PC to your TV. DVI will also carry audio assuming you have the right video card in your PC and right cable. DVI will give you HD quality video and sound.

There are multiple modes such as DVI-D (digital only), DVI-A (analog only), or DVI-I (digital and analog). Featuring support for analog connections as well, the DVI specification provides optional compatibility with the VGA interface.

Audio

This one might be a bit hard to spot. It will bring in stereo sound from your Computer to TV. You will see something like Mic In or Line In. If you have an Ipod, you could plug it in to test that you have found it. If your TV does not have an Audio Input we will use the RCA Audio connection, hook up to your stereo or set up speakers.

USB

USB (universal serial bus) is also making its way to TV’s. And it is a great idea that it is, because you can just plug in your flash drive or hard drive and stream you audio and video content straight to your TV with no need to convert to a different format and burn them on DVD. Older TV USB ports will only support pictures and music. Only the latest TV’s will do video files in certain formats. With the variance with this device, we would most likely not consider it for use.
