Can you use an HD cable box with a non-HD TV?
This depends on the cable box. Most HD cable receivers have not only an HDMI output for use with HD televisions but also feature analog connections that can be used with non HD televisions. The analog outputs will only deliver SD quality so the benefits of an HD receiver won't be seen, but the receiver most certainly can be used and will display HD quality whenever an HD television is connected to it.
High definition signal analog tv?
A number of years ago, in the early days of consumer HD television there was an analog high definition component signal format available. Since then, manufacturers and content publishers have agreed that HDMI is the only HD interface to be available on equipment. Although the signal interface also carries audio and other data on a single cable, it does not benefit the consumer. It is unlikely that any other analog interface will become available for HD signals. There are a number of adapters that can accept HDMI signals and deliver an analog signal, normally in the form of a VGA signal. Some work better than others but many can be adversely affected by HDCP (High bandwidth Digital Content Protection) which can prevent the signals being converted to their analog form.
How do you watch sports without cable TV?
There are two answers to this, depending on what the poster actually means with the question, so the question is reworded and answered twice below: 1 - Can an HDTV work without HD cable? HD televisions can display both HD and SD signals. Putting an HD television into a system as a replacement to an SD television will still allow all the sources to operate as they have done in the past, even though no HD signals aver reach the television. As and when an HD source is available, the television will display that in HD resolution. 2 - Are HDTV programmes available without using an HD cable receiver? HDTV as a signal format can be sourced from HD cable receivers. However, if there is no HD cable receiver, or not cable service at all, satellite is another platform that can be used for HD reception. Alternatively, HD signals can be generated using high definition DVD. HD DVD and BluRay are the two formats available and both will deliver HD signals from an HD disc.
Can component cables give you 1080p quality standard?
"Component cables" normally refer to a set of three cables that carry analog television signals. There is an HD format for analog component signals but it does not support 1080p, only 1080i and 720p. In addition, equipment being sold from 2009 onwards does not support analog HD. Commercial pressure from program producers has resulted in HDMI being the only HD interface that is commonly available. HDMI supports content encryption to prevent copying of HD content and has replaced virtually all analog HD interfaces.
Will satellite TV be all HD in February 2009?
No. All satellite TV is digital now. Some satellite TV is HD now, and more will be switching from HD to "standard" resolution. The February 2009 analog-to-digital switchover in the United States has nothing to do with HD. The digital conversion changes the format of the over-the-air broadcast channels from analog to all digital. But if you have satellite or cable TV, you don't get "broadcast" signals anyway.
Can i use component cables for HD?
Once upon a time there was such a thing as HD component signals. They were analog, used three wires and carried HD signals in the same way that SD component signals were carried. Today, we have HDMI. This is the digital version of component, includes audio and other signals and comes in a convenient single cable. Manufacturers and content providers have jumped on the HDMI connector since its launch because it also supports a copy protection system known as HDCP. This encryption prevents signals being copied and pirated. The desire of the film and television industry to reduce pirating means that HDMI is the only HD interface available on modern equipment. If you happen to own older HD equipment, you may well have the use of HD component signals but do be aware that any source equipment available now will not support analog component and it is virtually impossible to obtain an HDMI to analog converter. The few that do exist are almost all non approved devices and cannot be guaranteed to operate in the future.
Is the HDTV analog?
HDTV is a purely digital signal format today. There are in fact some analog standards for carrying HD component signals but they have fallen into disuse. Within the broadcast domain, HD is only digital and within the domestic market, HD sources are now using HDMI exclusively.
Can you play 720p on composite cable?
Composite video signals are used with standard definition video. There is no composite encoding system for HD signals. As 720p, 1080i and 1080p are all HD signals, they cannot be carried on a composite signal.
Do you need a high definition TV if you have digital cable?
Using HD TVSome satellite and cable networks do broadcast 720p HD, at this stage there are no full 1080 HD broadcasts. You need to live in an area where this service is provded and you'll need to pay a subscription fee and you will need a digital receiver with an HDMI output to your TV. Also, you can watch analog or non-HD digital programing on a HDTV. To enjoy the better resolution that HD offers, you need to get HD signals from somewere: Free HD broadcasts with an antenna, HD cable, HD satellite, HD/BluRay DVDs...
Can you connect a high definition tv to regular digital cable?
Co-ax cable is quite capable of carrying HD signals as part of a domestic cable service. However, optical fiber is now far more cost effective than copper so it si increasingly used for trunks with copper links carrying signals the last few feet into a home. Some are now taking fiber right into the home. Regarding video signals within the home, co-ax cable is used to carry composite video (standard definition color signals) and this will not carry HD signals. This is purely because coaxial interfaces for HD in domestic equipment. Coaxial cable is still used widely in broadcast environments to carry SD and HD signals.
Are tivo's compatible with HD tv's?
Tivo's are compatible with HDTV with many combinations of hardware and performance. # Tivo's HDseries3 records and plays back HDTV signals for best HDTV experience. You need the HD signal from satellite, cable, or (antenna) channels. The series3 has the HDTV format NTSC tuner and is reverse compatible with the old analog ATSC tuner capabilities. # The FCC mandated that all DVDR'S manufactured after March 2007 be HDTV compatible. TIVO ended series2 production and responded with the series3. # Tivo series2 records and plays back the standard analog ATSC signal for non-HDTV viewing. Your HDTV must have an analog input capability or analog tuner to view the lower quality analog signal. You need the analog signal from your satellite, cable, or local broadcast (antenna) channels. Series2 devices only have the ATSC tuner. # Satellite and cable providers will promote the new HDTV format but will continue to provide the lower quality analog signals in their packages. You need want the HDTV package view HD quality programs. A series2 Tivo will only store and replay the lower quality analog signals. # Feb 2009 the analog signal channels will no longer be locally broadcast by antenna. The FCC is administering a program to provide each household a converter to modifying the HDTV signal to the lesser quality analog channels. You will need this converter to continue using the Tivo series2 with antenna supplied signals. The question then becomes, WILL TIVO SUPPORT THE SERIES 2 DEVICES WITH PROGRAM GUIDE INFORMATION?
What is HD Component Video Inputs?
HD television signals are always in a component format. There are three signals that between them carry brightness and color information. Almost all domestic equipment uses an HDMI interface to carry the signal in a digital format now but there is also an analog HD component standard. The analog component connector is either on three RCA connectors or three BNC connectors. Pressure from the film and television industry has persuaded manufacturers to adopt HDMI as the only HD interface on modern equipment. As a result, HD analog component inputs to displays are virtually redundant now.
