Today's Show:
We receive emails all the time from listeners asking us about cables. Many ask what they would be missing of they were to use Component cable instead of HDMI. From a picture point of view your not giving up too much. From an audio point of view you would need to run eight RCA cables to bring in Dolby True HD or DTS MA sound tracks. Eight cables for audio and three for video. That's eleven cables to do the work of one HDMI cable. So with such a big advantage in cable management alone, we found it interesting that professional installers preferred to use component cables.

HDMI or Component from a professional Installer's Point of View

On today's show we discuss an article in CE Pro titled HDMI or Component? Integrators Weigh In written by Donna Englander that will explain why so many professionals prefer component cables. It all comes down to reliability.

The main job of a professional installer is to make the viewing experience as bullet proof as possible. HDMI in its early stages was anything but that. Many professional installers agree that the specification has come a long way since its version 1.0 implementation but few are ready to give HDMI another shot. With version 1.3 most of the handshaking issues have been eliminated and devices that support V1.3 play together nicely. But there is no denying that for long runs (50 feet or more) HDMI has its issues. If you are using HDMI for a local setup we don't think anyone will argue that its the easiest and best way to go. If you are setting up a projector room or whole house video where the equipment and the projector are separated by a large distance component is the only real way to go.

The main complaints about HDMI cables are:

  • You can't reliably run HDMI cables as far as component cables
  • You can't make custom lengths
  • No good HDMI via Cat 5
  • Cost
  • HDCP not working

Advantages of HDMI:
  • Audio and video on the same cable
  • Future Proof

Things to Consider:
  • The HT Guys have successfully used a 50 foot HDMI cable for a review (Podcast 100)
  • HDMI version 1.3 is the is the most reliable when it comes to HDCP handshaking
  • You can buy a 25 foot HDMI 1.3a cable for around $40, 50 feet goes for about $135 and 100 feet go for about $255. Still less than a premium priced two meter HDMI cable.
  • Test the connection prior to completing your installation.
  • Make sure you can return the cable if it does not work.
    Additional Reading:
    Long time listener and friend of the show Joe sent us a link to an article in EDN that talks about all the confusion in the HDMI world. It seems that the HDMI group has their work cut out for them. Check out NAB 2008: Audio Precision Ameliorates HDMI Confusion.

The other big advantage for HDMI is the use of good upscaling DVD players (such as the Oppo Digital). If you don't use HDMI you can't upscale more then 480p.

Unless you have a native 480p CRT for viewing SD DVDs. Then you don't need to upscale.

If the structural wiring is to be sealed up without any future access I always run both component and HDMI for the client; been that way since DVI was available. Not doing so borders on professional negligence... analog component will be shut down altoget

I agree. My brother only had component put in. At the time I asked why component instead of HDMI and the installer told me HDMI was not always reliable. Unfortunately, at the time I did not know enough to argue with him. So now my brother is paying th

I have my Sony DHG-HDD500 DVR connected to my Toshiba 26" HD LCD TV via component cables. SD TV programs seem alot clearer and the picture was spread across to the widescreen automatically. Additionally, the TV reports the signal is at 1080i. I did have t

Broadcast will be the last service to shut down analog component but this has already been a problem in the form of DVD players and this year, some blu-ray players. To be clear, I would not run HDMI/DVI only in a sealed structural wiring application ei

I hooked up both HDMI and component and then switched using the TV. The image looked better with HDMI so that is what I use. That's not a very scientific test. What was the source (cable, SD DVD, HD

Sorry I didn't make it clearer. I made sure all the settings were the same on the TV for both inputs. The source was my cable box. I tested both SD channels (480i) and HD channels (1080i). The TV is a 1080p 65" Mitsubishi DLP rear projected TV (WD-6

Technically, proper analog component and HDMI should be equals for the scan rate/bandwidth they were designed for. How a display deals with them is another story and there is no consistent response - it has to be tested. As an ISF calibrator I always h
