1080iResolution of a video signal 1,920 pixels (horizontally) x 1080 pixels (vertically); the i stands for "interlaced scan" which produces less-smooth motion video than progressive scanning.
1080pResolution of a video signal 1,920 pixels (horizontally) x 1080 pixels (vertically); the p stands for "progressive scan" which produces smoother motion video than interlaced scanning. This format works the same as the 720p format, but has higher pixel resolution.
2.0 channel soundAlso known as stereo sound, or 2-channel. The 2 indicates two distinct channels (left and right) and the zero means there is no low frequency channel for a subwoofer.
2.1 channel soundThe 2 indicates stereo sound with two distinct channels (left and right) and the one means the signal includes a low frequency channel designed for a mono subwoofer.
2160pResolution of the video signal is 3028 or 4096 pixels (horizontally) x 2160 pixels (vertically); p stands for progressive scan which produces smoother motion video than interlaced scanning. This format works the same as the 1080p format with higher pixel resolution.
300-Ohm cableAn older technology used to connect TV antennas to the TV. Most 300-Ohm is converted to 75 Ohm with the use of a simple and inexpensive transformer.
480iResolution of picture is 852 pixels (horizontally) x 480 pixels (vertically); i stands for interlaced scan which produces motion video not as smooth as interlaced scanning. This is native DVD resolution; it is a wide-screen format but not considered a high definition format.
480pResolution of a picture is 852 pixels (horizontally) x 480 pixels (vertically); p stands for progressive scan which produces smoother motion video than interlaced scanning. This is a wide-screen format but not considered a high definition format.
5.1 channel soundA surround sound system that consists of front speakers (right and left), rear speakers (right and left), center channel speaker and a subwoofer. The subwoofer is the .1 channel also known as the Low Frequency Effects channel (LFE). This is also the audio standard for digital TV and HDTV.
5.1.2 channel soundA Dolby Atmos surround sound system that consists of front speakers (right and left), rear speakers (right and left), center channel speaker and a subwoofer. The subwoofer is the .1 channel also known as the Low Frequency Effects channel (LFE). The .2 indicates two channels for ceiling speakers, or speakers designed to bounce sound off the ceiling to simulate overhead action.
5.1.4 channel soundA Dolby Atmos surround sound system that consists of front speakers (right and left), rear speakers (right and left), center channel speaker and a subwoofer. The subwoofer is the .1 channel also known as the Low Frequency Effects channel (LFE). The .4 indicates four channels for ceiling speakers, or speakers designed to bounce sound off the ceiling to simulate overhead action.
6.1 channel soundA surround sound system that consists of front speakers (right and left), front center channel speaker, rear speakers (right and left), a rear center speaker, and a powered subwoofer.
5.2 channel soundA surround sound system that consists of front speakers (right and left), front center channel speaker, rear speakers (right and left), and two powered subwoofers.
7.1 channel soundA surround sound system including one subwoofer, one center, and two each of front, side, and rear speakers.
7.1.2 channel soundA surround sound system including one subwoofer, one center, and two each of front, side, rear, and two Dolby Atmos ceiling speakers.
7.1.4 channel soundA surround sound system including one subwoofer, one center speaker, and two each of front, side, rear speakers, with four Dolby Atmos ceiling speakers.
720iResolution of the video signal is 1,280 pixels (horizontally) x 720 pixels (vertically); i stands for interlaced scan which uses less bandwidth, but produces less smooth motion video than progressive scanning.
720pResolution of the video signal is 1,280 pixels (horizontally) x 720 pixels (vertically); p stands for progressive scan which produces smoother motion video than interlaced scanning.
75-Ohm cablePrimarily RG59/U or RG6/U coaxial cable used to carry audio and video signals over one cable. RG6/U is recommended for highest quality coaxial cable performance and to "future proof" installations. RG6/U is a must for DSS satellite installations.
960HCCTV camera resolution equivalent to 960 x 480 pixels.
