Browse Forums Home Theatre & Automation 1 Nov 24, 2011 10:04 pm I'm just about to have some wiring done, and would like to have some HDMI wiring done such that all I have at the screen and at the source are HDMI connections; how are the wiring usually done? With Cat6 in-wall, or with HDMI cables plugged into the keystone? Re: Wiring HDMI 3Nov 25, 2011 10:09 am I would run both. TV's and PVR's will all have internet capability very soon. And as Casa has done, run empty conduit from blank wall plates up into the ceiling where ever you think you might want to run more cables. Saves heaps of money and time if done at pre-plaster than done in future years. Even more so if you have double brick. The other thing to consider is length of cable runs. Although there is no defined maximum for HDMI, you will suffer signal attenuation (ie corruptions) the longer you go. an extract from wikipedia..... "Although no maximum length for an HDMI cable is specified, signal attenuation (dependent on the cable's construction quality and conducting materials) limits usable lengths in practice. HDMI 1.3 defines two cable categories: Category 1-certified cables, which have been tested at 74.5 MHz (which would include resolutions such as 720p60 and 1080i60), and Category 2-certified cables, which have been tested at 340 MHz (which would include resolutions such as 1080p60 and 2160p30). Category 1 HDMI cables are marketed as "Standard" and Category 2 HDMI cables as "High Speed". This labeling guideline for HDMI cables went into effect on October 17, 2008. Category 1 and 2 cables can either meet the required parameter specifications for interpair skew, far-end crosstalk, attenuation and differential impedance, or they can meet the required nonequalized/equalized eye diagram requirements. A cable of about 5 meters (16 ft) can be manufactured to Category 1 specifications easily and inexpensively by using 28 AWG (0.081 mm²) conductors. With better quality construction and materials, including 24 AWG (0.205 mm²) conductors, a HDMI cable can reach lengths of up to 15 meters (49 ft). Many HDMI cables under 5 meters of length that were made before the HDMI 1.3 specification can work as Category 2 cables, but only Category 2-tested cables are guaranteed to work" Whereas Cat6 can go up to 90mtrs for gigabit connections and 35-55 for 10Gb (depending on how noisy the environment is with other cable runs particular 240v cables) Also keep in mind where your FTTH connection is likely to be (if if if it ever happens...but thats another discussion) as you will want to run gigabit connections from that to your router/switch to maximise its (supposed) speed benefits.

Re: Wiring HDMI 5Nov 26, 2011 5:20 pm PHL I was actually wondering if there are special HDMI wiring, or to use a pair of Cat 6 terminating on HDMI wall plates, or I've also seen wall plates with HDMI connections both sides, ie a standard HDMI cable is used in wall, terminating on HDMI wall plates. HDMI over Cat6 works as you use powerd adaptors at either end to send/ receive the signal. only needed at the ends if you are going witha structed cabling package then this is easy to send this signal to any place (not via the network switch tho) while HDMI - mech socket only uses the HDMI all the way.. personally you should only look at HDMI signaling if you want to transmit foxtel from two boxes + IR extenders around the house... if you want to send other 1080p content look at getting a Home file serve/ NAS / Shared drive to store you movies on and any PC/ Media player to broadcast it or physically move the disc around the house Kodiak Data Cabling onFaceBook Consult*, Design and Installation Data, TV, Home Theatre/ AV Cabling, Multi Room Audio, IP CCTV and Door Intercoms Ask for a Quote. *DIY DATA Cabling Is Ilegal Re: Wiring HDMI 6Nov 26, 2011 11:05 pm Pugs PHL I was actually wondering if there are special HDMI wiring, or to use a pair of Cat 6 terminating on HDMI wall plates, or I've also seen wall plates with HDMI connections both sides, ie a standard HDMI cable is used in wall, terminating on HDMI wall plates. while HDMI - mech socket only uses the HDMI all the way.. personally you should only look at HDMI signaling if you want to transmit foxtel from two boxes + IR extenders around the house... The cabling is just so I can hide the receiver, PS3 and media streamer in a cupboard, so is a relatively short run from them to the TV. For media storage and server, I'm already using 802.1ad from my ts439 Pro to my switch. I'm actually now wondering if just a straight cable in a conduit (in case of upgrades) would not be the easiest setup, as the termination is not visible and would eliminate 4 connections, but would have preferred a cleaner look with wall plates. |
