What is HDX?

HDX is a modern display technology developed by Vudu. It offers great audio and video streaming services.

It offers a resolution of about 1080 pixels and more than 1 GB memory. It encodes the video at twice the bit rate of that of HD.

Also, it has the capability of varying bit rates according to video scenes. It preserves the video streaming rate at 24 frames per second.

Adaptive technology uses a compression algorithm for enhanced visual display. Also, its touch-free feature offers a seamless experience to LAN and even WAN clients over large distances.

However, HDX also has some disadvantages. It takes more time to download a video than to stream it.

 

What is HD?

HD stands for High Definition. It is a display technology that has eclipsed the primary SD.

The NHK Broadcasting Corporation of Japan began its research on HD technology in 1964. It created a new system called NHK color in 1972.

The Society of Motion Pictures and Television Engineers became the standard authority for HD technology in the world. At its inception, it was headed by Charles Ginsburg.

The compression techniques were used because the uncompressed video used a lot of bandwidth. A video with HD quality downloads faster.

The special feature of HD display is that it doesn’t depend on the size of the screen. As long as the pixel measurement is 1280 × 720, the display would be called HD.

The full HD or FHD is an enhancement of HD display technology. It has the pixel measurement of 1920 × 1080 pixels.
