Part 2: Why RCA Scenium DLP™ is better?

DLP™ is just part of the story. You have chosen to embark on the next generation of TV viewing— HDTV. There are many technological advancements that make HDTV better than analog TV, but there are basically three things about HDTV that bring you a superior viewing experience: (1) resolution, (2) aspect ratio, and (3) digital signal and sound.

Resolution (it’s math...that works for you)

The crisp, lifelike picture people rave about when experiencing true HDTV is due to the resolution this technology provides. The resolution is measured by calculating the number of active lines of pixels. A pixel (which stands for picture element) is a small dot. The picture you see on your TV is composed of these dots.

A regular, analog television (called analog) only has a resolution of about 200,000 pixels (480 vertical pixels x 440 horizontal pixels = 211,200 pixels). The HDTV format is capable of more than 2 million pixels (1,920 x 1,080 = 2, 073,600).

More pixels equals more detail. In summary, HDTV is capable of resolution that is up to 10 times the resolution of the picture on a regular, analog TV!

Aspect Ratio

Aspect ratio is simply the width and height of the picture. Regular TVs use a 4 x 3 (also written 4:3) aspect ratio, which means the picture is a little wider than it is tall (a screen that is 20 inches wide is about 15 inches tall).

When the standards were being developed for television broadcasting in 1941 by the NTSC (the National Television Standards Committee), it made sense to adopt the 4 x 3 aspect ratio that the film industry was using at that time.

As TVs dropped in price and people prospered in the 1950s, the movie industry had to find a way to get people out of their living rooms and back to the movie theatres. That’s when they created the 16 x 9 (also written 16:9) aspect ratio (also called widescreeen format). When the standards for HDTV were being developed by the ATSC (Advanced Television Standards Committee), the 16 x 9 aspect ratio was chosen as the format for HDTV.

This widescreen format makes sense because it’s much closer to the way we see. Our field of vision is actually much wider than tall because of our peripheral vision. Not only is it closer to the way we see, but the pictures are crisper and cleaner with more detail in the close-up and panoramic views.

HDLP61 specifications

The RCA HDLP61 is a high-definition rear-projection television that was introduced in the early 2000s, capturing the attention of consumers seeking a balance between performance and affordability in large screen televisions. With its sleek design and impressive specifications, the HDLP61 quickly became a popular choice for home entertainment.

One of the primary features of the RCA HDLP61 is its substantial 61-inch screen, which allows for an immersive viewing experience. The television utilizes DLP (Digital Light Processing) technology, a key aspect that contributes to its high-quality picture display. DLP technology relies on a digital micromirror device (DMD) to reflect light and create images, which results in vibrant colors and sharp details. This technology also minimizes the risk of image burn-in that can be a concern with other display types such as CRT and plasma.

The HDLP61 supports a native resolution of 720p, providing clear and crisp images that enhance the viewing of high-definition content. Additionally, it is compatible with 1080p signals, making it a flexible choice for various types of media sources, including cable, satellite, and Blu-ray players. The television also features a 16:9 aspect ratio, which aligns perfectly with modern high-definition content.

In terms of connectivity, the RCA HDLP61 is equipped with multiple input options, including HDMI, component, and S-Video ports, allowing users to connect various devices such as gaming consoles, DVD players, and streaming devices with ease. This versatility ensures that users can enjoy a wide range of entertainment options on the large screen.

Another notable characteristic of the HDLP61 is its built-in audio system, which includes speakers that deliver decent sound quality, complementing the visual experience. However, audiophiles may opt to connect external sound systems for a more robust audio experience.

The RCA HDLP61 is also designed with user-friendly controls and features, including an intuitive on-screen menu that makes navigating settings a breeze. The television also includes features such as adjustable brightness, contrast, and color settings, allowing users to customize their viewing experience according to personal preference.

Overall, the RCA HDLP61 stands out in the realm of rear-projection televisions because of its combination of advanced DLP technology, vast connectivity options, and user-friendly design. It continues to be remembered as a budget-friendly option that delivered good performance during its time in the consumer electronics market.
