| FAQ | Frequently Asked Question |
| H.264 | H.264 is a standard for video compression. |
| HDMI | HDMI (High-Definition Multimedia Interface) provides an interface between any compatible digital audio/video source, such as the VUDU box, to a digital television set. The HDMI connection is capable of 480i, 480P, 720P, 1080i, and 1080P resolutions and carries both the audio and video on a single cable connection. |
| HDTV | High Definition Television. An HDTV is a digital TV set that is capable of receiving high definition signals. These signals are usually in widescreen (16:9) format, and in 720P, 1080i, and 1080P resolution. |
| Hub | Similar to a switch except that traffic from one connection point is broadcast to all others. |
| Interlaced Video | With Interlaced Video, the individual images of a video sequence are created by scanning a scene line by line. |
| IP Address | Internet Protocol Address. An IP address is a numerical sets of numbers consisting of 4 blocks of up to 3 digits each in the range of 0 to 254. Every device on a network must have its own unique IP address. For LANs there are special sets of IPs that are used. These consist of the following blocks: 10.x.x.x — where x = a number from 0 to 254. 192.168.x.x 127.x.x.x 172.x.x.x 169.x.x.x All other IP address blocks are considered public and are for use as WAN addresses. |
| IR Remote | IR remotes require line-of-sight to the source in order to control the device. Most universal remotes, such as the Logitech Harmony series, are IR based remotes. |
| ISP | Internet Service Provider |

| Quick Start Guide | The pamphlet that was included in the box for the VUDU STB. The guide can also be downloaded from (tbd) |
| RCA | RCA cables are the traditional yellow, red and white connectors found on most video devices. The three connectors transfer both video (yellow) and stereo audio (red and white). |
| Reboot | To reset the VUDU box. A soft reboot is to programatically reset the VUDU box without interrupting the power source. A hard reboot is to phsically disconnect and then reconnect power to the VUDU box. |
| Remote Pairing | The process in which the remote control is linked with your VUDU STB. |
| RF remote | The VUDU box features an RF remote. This means that the remote does not need line-of-sight with the VUDU STB to communicate. This also offers a quicker response than most IR remotes will give. |
| Router | A router is a networking device that allows for a home network to connect to the internet. Typically, the router will be put into place in between a modem and the computer or network devices that are configured to go online. |
