Will switching from HDMI to RCA affect my PlayStation 3’s performance?

Purchasing a PS3 or an Xbox has become super trendy in today’s hi-tech world. Gaming consoles are replacing the traditional computer at an astonishing fast rate. The enhanced picture and sound has made these gaming accessories must-have devices.

Switching from HDMI to RCA cables

If you switch from High Definition Multimedia Interface (HDMI) to Radio Corporation of America cables (RCA) you will notice a drastic change in the picture and sound quality on your PS3. This is because the RCA cables use basic inputs. These inputs do not thus enhance the quality of the video being transmitted. The cables simply transmit the data from one source to another.

HDMI (High Definition Multimedia Interface)

HDMI cables act as a source for transmitting data to a display device. While it may seem that HDMI cables are similar to RCA connectors, the technological advances used by HDMI cables make them superior to other data transmitting cables. These connectors support video up to 1080 pixels, the highest possible resolution today. Modern games are made to make the most of high end graphics cards and hence using HDMI cables in this situation is an ideal choice.

RCA (Radio Corporation of America) connectors

As mentioned earlier, RCA connectors do not use the latest technological inputs and hence are thought to be inferior to HDMI cables. Switching from HDMI to RCA will allow you to play games or watch movies on your PS3 but it is a backwards step. This is because HD games are not entirely compatible with SD resolution connectors.

If it is quality that you are looking for, you will be better off with an HDMI cable.

HDMI vs. DVI – What is the difference?

Have you recently purchased a new HDTV? Are you going to connect your PlayStation, Xbox 360 or Blu-ray player to your TV set? If yes, there are many connectivity options available. While DVI (Digital Visual Interface) was an option many people chose in the past, HDMI (High-definition Multimedia Interface) is the latest available connectivity option.

The features of both technologies:

Digital visual interface (DVI)

This technology was initially designed to carry uncompressed digital video data. While DVI interface was initially used just for computer monitors, it is now available for televisions as well. The number of connectors available on the DVI cable represents its different functionality. Three different types of connections are available in DVI.

• DVI-A (analogue only)
• DVI-I (digital and analogue)
• DVI-D (digital only)

High-Definition Multimedia Interface (HDMI)

This is an all-digital video/audio interface capable of transferring uncompressed streams. Unlike DVI, HDMI has the ability of carrying audio signals as well as video.

How is HDMI different from DVI?

The specifications of HDMI are derived from DVI. Thus, they have many things in common. For example, both support digital transmission. However, there are two big differences between HDMI and DVI.

• HDMI supports analogue audio alongside video (DVI only supports video)
• HDMI includes content protection known as HDCP (High Definition Content Protection)

As HDMI is a successor to DVI, HDMI and DVI are quite similar. This is one reason for the existence of backward video compatibility. However, while video is supported by both, DVI does not offer any support to audio.

HDMI technology – a change in the AV industry is here

HDMI or high definition multimedia interface is the innovative new technology in the AV (audio/video) industry. The technology makes it possible to combine the audio and visual signals and offers exceptional advances in digital entertainment.

The HDMI technology was jointly developed by Sony, Philips, Panasonic, Toshiba, Hitachi, Thomson and Silicon Image. It has also been a driving force behind high-definition TVs, HD-DVD, Blu-ray players and all other types of AV products.

Defining HDMI cables

An HDMI cable is a simple plug-in device that transmits high definition video resolution and multiple audio channels using a single cable. These cables work by transmitting digital signals from the AV source, be it a DVD player, an A/V receiver or a satellite receiver to another digital device.

As all HDMI cables have 24 bit 8 channels, they are able to carry transmission of uncompressed audio. However, they also support compressed audio formats like DTS and Dolby.

Features of HDMI cables

HDMI cables have the capacity to carry high quality video – 720p, 1080I and 1080p. Multi channel surround sound and stereo output is also a part of the HDMI package. Moreover, HDMI technology also supports formats like NTSC, PAL and 480p.

As HDMI technology carries digital data, it is highly superior to analogue devices. Unlike analogue cables, there is no compression of data. This eliminates the loss of audio or visual details.

Use HDMI cables for connecting audio-visual equipment

In the recent past, HDMI has become a standard interface for all audio visual equipment. Using HDMI cables, you can easily connect your home cinema system or HDTV with other audio visual equipment.

An HDMI cable can carry a bandwidth of 5GBps. This is almost twice the bandwidth required for transmitting multi-channel video and audio. Besides this, there are many other factors that make HDMI cables stand apart from their predecessors such as S-Video, composite video and component video.

Why HDMI cables are better

HDMI (high definition multimedia interface) is basically a means of transmitting an uncompressed form of digital signal. All earlier cables used analogue interfaces for transmitting data. When it comes to analogue, a clean digital source is initially converted into less accurate analogue signals, sent to the TV set and then converted back into digital to display on screen.

During each conversion, the digital signal tends to lose its integrity. This results in distortion of image quality. On the other hand, HDMI cables preserve the source signal. As the need for analogue conversion is completely eliminated, HDMI cables are able to deliver the richest and sharpest pictures.

Earlier video interfaces required different audio cables. In the case of HDMI cables, they have abundant speed and bandwidth. Due to this, they are capable of carrying video along with eight audio channels for uncompromised surround-sound. For the best HDTV viewing experience, HDMI cables are a better option for connecting audio visual equipment.
