There are several signal types used in audio-visual equipment. Older hardware uses analogue signals, while newer devices use digital signals. Some analogue signals work by splitting information into various components, hence the name "component video". There are usually three components involved in consumer video electronics that use component outputs. One component carries a luma (brightness) signal, while the other two carry colour information. This type of output is known as "YPbPr component video" output.
Because digital signals are now the standard, newer televisions and monitors often do not have input jacks for component signals. Instead, computer monitors accept either DVI (Digital Visual Interface) or DisplayPort digital connections, and televisions accept HDMI (High Definition Multimedia Interface) connections. Component to HDMI converters are used in cases where users need to connect the output from an analogue device to a digital display.
Component to HDMI converters are available at electronic stores, hardware outlets, video specialty stores, and some department stores. They are also available online, at electronics websites and Internet marketplaces like eBay. Before making a purchase, buyers should verify the output and input connections on their devices. Buyers must also consider factors specific to their equipment and setup.
Types of Analogue to Digital Converters
There are many different kinds of converters available, and buyers may feel at sea when they start shopping for a component to HDMI converter. Some devices simply change the physical form of the connection, while others convert the signal from digital to analogue or vice versa. The most common types of converters available are described in the following sections.
VGA to HDMI Converter
VGA to HDMI converters are often used to connect a computer to a television that has HDMI inputs. VGA to HDMI converters accept analogue signals through a VGA connection. Since HDMI combines audio and video, many of these converters also include an audio input. The analogue video and audio signals are first converted to digital signals, then are combined, and are finally sent out through the HDMI output.
DVI to HDMI Converter
A DVI to HDMI converter is also used to connect computers to televisions. Since both DVI and HDMI are digital signals, the converter need not convert the signal from analogue to digital. However, DVI carries only video, not audio signals; therefore, there are actually two types of DVI to HDMI converters. The first is an adapter that carries the digital video from the DVI input to an HDMI output. The second includes an audio input, and combines this with the digital video before moving the signal to the HDMI output.
Component to HDMI Converter
Component to HDMI converters are usually used to connect older video sources (e.g. DVD players, Apple TV and game consoles) to newer televisions. Component signals are analogue, and they must be converted to digital before they can be played via a TV's HDMI input. The component cable usually consists of three RCA connectors; these are coloured green, blue, and red. Component converters also usually include two audio inputs. The five RCA inputs are then combined and converted to a digital signal that gets transmitted out through the HDMI end of the converter. Since digital signal conversion must take place, it is not possible to achieve the same result with a only cable that has component connectors on one end and an HDMI connector on the other.
Composite to HDMI Converter
Composite video is an older, analogue standard for video; it gets converted to digital HDMI via composite to HDMI converters. This standard is still widely used, and can be found in older VHS players, DVD players, security systems, and video cameras. Unlike component video outputs, which have three RCA connectors, composite outputs feature just one connector for the video signal. Composite to HDMI converters usually include two more input connectors for audio input.
Multi-source to HDMI Converter
Also known as multi-format converters, multi-source to HDMI converters offer multiple input connectors for different kinds of signals. Buttons or switches let users select the input source, which is then converted to digital HDMI. Multi-source to HDMI converters accept a combination of composite, component, DVI, HDMI, or VGA inputs.
Digital to Analogue Converters
The converters discussed above all convert analogue signals to digital ones. Users should note that these converters do not work in reverse. Other converters are required to convert digital HDMI signals to older analogue signals. Some of these include the following:
- HDMI to DVI converter
- HDMI to VGA converter
- HDMI to component converter
The above converters are useful when connecting newer video sources to HDMI output (e.g. Blu-ray players) to older televisions that accept analogue signals.
The Difference between Component and Composite Output
Both component and composite video use analogue signals. However, component signals separate the components into colour information and luma, while composite signals combine the luma information with the colour channels. It is not possible to use a component to HDMI converter with a device that outputs composite signals.
Devices that Use Component to HDMI Converters
Any video source that outputs video as component YPbPr signals can use a component to HDMI converter to connect with a modern television or display that accepts digital HDMI connections. Some of the common consumer devices that use this signal and connector include:
- DVD players
- Video projectors
- Early gaming consoles
- Video cameras
- Video surveillance systems
- Set-top boxes
- Personal video recorders (PVRs)
A quick look at a device's output connectors is enough to confirm the presence of component output. Component connectors generally feature three RCA connectors; these are coloured green, blue, and red.
Factors to Consider when Purchasing Component to HDMI Converters
All component to HDMI converters convert an analogue component video signal to a digital HDMI signal. There are two other factors that buyers should consider before purchasing a converter. These factors are the converter's output resolution, and how to use converters over long distances. These two topics are discussed in depth in the sections below.
Output Resolution of the Converter
There are four versions of HDMI (1.0, 1.1, 1.2, and 1.3) that are currently available. The versions denote changes in the types of audio that can be transmitted. All HDMI versions can transmit video up to 1080p (full HD). All converters have a maximum output resolution that, in some cases, may be lower than 1080p. Some converters also can scale lower resolution input signals to higher resolution outputs.
Using Converters over Long Distances
All transmissions experience deterioration when transmitted via cable over long distances. This is equally true of HDMI signals. Users should keep the converter as close as possible to the television to minimise the length of cable required. However, if this is not possible, buyers should consider purchasing an HDMI extender,, or a set of HDMI to Ethernet converters,, to maintain the quality of the HDMI signal.
Buying Component to HDMI Converters on eBay
Buyers in search of component to HDMI converters can find a wide selection and a convenient shopping experience on eBay. To begin looking, buyers just need to enter a search term into the search bar on any page on eBay, including the eBay home page.. Buyers in search of a specific converter just have to include relevant keywords in the search field. For example, a search for "1080p component to HDMI converters" displays a list of all the 1080p converters available on eBay at present. After selecting a category, the results can be filtered based on various criteria including condition, price, and delivery options.
Before making a purchase, it is recommended that buyers find out about the seller's return or exchange policy. Buyers can contact the seller directly if this information is not available on the item's page. Buyers can also arrange for local pickups from the seller if both parties are comfortable with the arrangement.
It is also a good idea for buyers to check out a seller's feedback score before committing to a purchase. Reading feedback is a good way to determine how well a seller has satisfied previous customers over the last 12 months. Sellers whose feedback scores and comment sections reflect a lot of positive responses are a good bet. They are more likely to provide quality merchandise, conscientious customer service, and prompt shipping than are sellers with a great deal of negative feedback.
Several different types of analogue to digital converters are available to convert video transmissions from one form to another. Buyers who want to use video devices that output analogue component signals with newer digital HDMI televisions can do so by using a component to HDMI converter. Since there are many types of converters, buyers must make sure they are buying one that meets all their needs.
Converters that are designed to convert from analogue to digital cannot convert signals from digital to analogue, nor vice versa. Buyers should also be aware that cables with component connectors on one end and an HDMI connector on the other do not convert the signal in any way. Before making a purchase, buyers should also consider the output resolution of the converter and the distance between the converter and the television or display.
Component to HDMI converters are available at brick and mortar electronic stores as well as online. Buyers looking for converters online can select from a wide range of component to HDMI converters that suit different requirements and budgets.
