TV advertising

Browns Butchery is located in Raymond Terrace, the original concept for the TVs was advertising material was created by a 3rd party company and uploaded to the store computer remotely to display on the TVs. Due to lack of communication of the 3rd, we were called in to create a solution where Browns Butchery can create there own ads and videos, then upload the material them self to the computer display on the TVs. We added the monitor to the existing computer, cabling to the TV’s, network hub and instructions on how to upload and display the advertising material.

Wi-Fi Vs Hard Wired Home Network and the Internet

With the advancement of wireless technology, how relevant is hard Marantz LAN backwiring your home to access the internet? You may be surprised to hear but it’s more important than ever. It is extremely important to ensure data passes through without interference to your Foxtel box, home theatre system, your TV, gaming systems like the PS3 or PS4 to enable streaming services like Netflix and Stan and stream music without dropouts too.

More and More internet capable equipment

We only need to look back about 5 year ago at how many devices we had that connected to the internet and then wireless devices in general, not as many as today right. Today we have everything from TV’s, home theatre systems, gaming consoles, phones, tablets (iPad and android), multi room audio systems and now even our watches can connect to the internet (apple and android watches), no doubt future internet capable fridge’s and washing machines will become a lot more price comparative, and then who knows what else will be internet capable.

So as more technology is introduced into our homes, our use if the internet will only increase, we cannot escape that, so a well-built infrastructure is necessary to maintain proper connection otherwise problems from slow to no connection at each/all devices will occur.

A well designed system

So we’ve established that the infrastructure is important, but where and how to start? If a device has both options to hard wire as well as wireless, always choose the hard wire option first if possible, only then will you be guaranteed that you will have the best connection possible, wireless should only be used as a last resort or if you cannot hard wire your device like a phone or tablet.

Apple TV backDevices like Foxtel boxes, TV’s, home theatre systems, computers, gaming consoles and most portable music systems (multi room audio systems) are all capable of being hard wired, if they are not hard wired, issues can develop from the device constantly buffering (trying to catch up) to the connection failing, especially noticeable if streaming HD movies from a NAS system internally (within your home) or externally using services like YouTube, Netflix or Stan.

The work involved to hard wire your equipment

Hard wiring your devices is not as simple as it sounds, unless your equipment is in the same room as your modem/router you can go ahead and plug it in and away you go. Australian standards in wiring rules exist everyone and if these are not followed, hard wiring your devices will become a waste of time and money. Without confusing you too much, data talking is like fax tones and for those of you that remember what a fax machine looks like and sounded like, it’s the same idea, if noise is introduced into the cabling due to poor installation, this will interfere with the sending and receiving data and hence being a waste of time and money.LAN port


Wi-Fi is a great idea but should only be used as a last resort, hard wiring all other devices will give you the best results for internet and data access, most equipment has a choice of either being wireless or hard wired, some are wireless only and some are hard wired only like Foxtel boxes for example.

HDMI to Cat6 Tx

How to send a Foxtel box into another room via HDMI, TV antenna or Data cabling part 2

Disadvantages are;

  • There is no built in option to change Foxtel channels from the second room without purchasing addition equipment.
  • HDMI modulator will cost more then an AV digital modulator, AV digital modulator use the yellow/red/white leads, there is a very noticeable picture quality difference between the two standard definition and high definition digital modulates.

Addition equipment to think about; if you would like the ability to change the Foxtel channel from the second, third, fourth ect room, there are devices available to connect to the TV antenna cabling to transmit the remote control back to the Foxtel box.

HDMI over cat6 data cable for multiple Foxtel boxes and longer runs

This option can solve all of the problems listed above, Single HDMI extension kitthere are also a few different options we have available by converting the HDMI into data cable.

The first advantage is, if you have a need to only transmit the Foxtel to one room, we can mix the HDMI signal from the Foxtel box on to a single data cable and then run the data cable up to 70 meters to any TV your home or outside into the man cave. This option is ideal for long runs and only to a single TV.

The second option is, locating all your Foxtel boxes in a single room/cupboard/comms cabinet so they are all out of sight and then mixing them all into a matrix bHDMI to Cat6 matixox. This type of system is too complex to explain in this blog but it can be expanded for example up to 8 inputs and 8 outputs, all 8 TVs have the ability to see all 8 inputs/devices connected, so in simple terms you could input up to 8 Foxtel boxes and HDMI to Cat6 matrix plantransmit to 8 TVs OR input 4 Foxtel, 2 Blu-ray players and a PS4 (as the PS4 uses Bluetooth for the controllers, you would have to be in the next room for this to work) and leave the last one spare for future use. This option gives you the ability to also change channels as well from all the rooms.


There is only one disadvantage, if you have an old TV connected and it is only a standard definition, the matrix will down scale the image to suit the oldest TV (to eliminate and conflicts in the picture), this means if you have a new HD TV or UHD TV, you will see the image in standard definition, this is only because if the old TV, once all the old TVs are updated, only then will the matrix transmit in full HD.


Depending on your requirements will depend on the equipment need, there is no reason why you can not do any of this yourself, but you need to understand that the more complex the system you go the more critical it is to correctly install the equipment, if not done correctly damage can occur to the equipment or the equipment connected. we always recommend something like this be install be a repeatable home theatre installation company.

Wi-Fi, why it may not be the best solution (Part 2)

Is There a Solution to Unblocking a Blocked Doorway?


Yes, there is a solution, every router not only has Wi-Fi, but can also be hard wired (plugged in) in as well. So this basically means that device can have a direct link to the router. So now for example a computer can directly access a networked hard drive with less of a chance of the connection slowing down. Now we’re created multiple doors (it’s one door per device now), if there is a hard drive directly connected to the network, that’s one doorway, and if some computers and TV’s connected directly connected, that’s more doorways created as well, this would end up freeing up the Wi-Fi for things like laptops and iPhone/iPads, android devices to have a more reliable connection to the internet or other devices in the home.


Installing Data Cables

Blog_Wi-Fi_StructuredCablingInstalling data cable could be one of you best investment you make, just short of decorating your house. I can hear it now, nothing beats decorating a house, but I’ll tell you why it’s an investment. We live in a technology orientated world, it’s around us and we can’t get away from it, as many devices then ever connect to the internet nowadays and will only increase as time goes by, so unless your 80 years old or want to be disconnect from the world, you will be connected in one way or another. Any building can be wired up but of course when a house is in the stages of being built is the best time to get it done. Electricians can wire up your house but this is not the wisest choice, if you have a look at our home automation blog, there we tell you why, but to repeat, there are many government rules and regulations and most electricians will ignore just too either get the job or to finish the job in a very fast manner. If the data cabling is not installed correctly, it can course major problems, anything from interference in the signal through the cable to not working at all to even causing fire or equipment damage. When planing out a data network in the house, not ever electrician will not know where to put outlet to future proof a home, and even to a point miss outlet out that are critical that needs to be done now, the amount of times we’ve seen this is unbelievable.


Internet Speeds

One thing to always remember is “your fastest speed is your slowest connection” and this is at the moment your internet connection, but with the NBN coming (National Broadband Network), streaming video, or any content that requires high bandwidth will be easier in the future as streaming faster internet speeds get better.

Wi-Fi, why it may not be the best solution (Part 1)

By Simon – Custom Audio Visual Solutions

Blog_Wi-Fi_DeviceConnectionIn recent years Wi-Fi technology with-in the home has been getting better, implementation for home theatre systems and TVs are getting much better by opening up many more opportunities with-in the home network to access the internet. But improvements happen that quickly that it feel like as soon as we buy a piece of technology, it’s already out of date as soon as it’s plugged in, unfortunately to get an easy and quick connection to the internet, this is a necessary evil. With more and more devises around the home that can be connected to the internet, Wi-Fi can very easily get congested and bring everything to a stop, even if only a few people as using it.


Problems with Congested Wireless Network


As mentioned, congestion is easily created, two or three people streaming video on different TVs or computers or even playing games over the internet can slow other computers uses down or even stop them from accessing anything on the home network or assessing the internet entirely. The problem doesn’t sit with the Wi-Fi but more with its limitations and the amount of devise connected, what they are downloading at that time. We could for example have 100 computers connected to a wireless network and if all those computers were only browsing the internet, everything would be ok. But then get two or three of those computer downloading video off the internet, or a smart TV accessing a hard drive with video streaming HD content, then there goes all the Wi-Fi space for the other computers, Another reason to reduce the use of Wi-Fi is if your controlling your home theatre amplifier off your smart phone or tablet, the signal needs to bounce from your device to the Wi-Fi and then to the amplifier, even though it is easy to setup wireless, the time it takes for the signal to travel is a lot longer and less reliable than through cable as Wi-Fi can be interfered with and produce errors in the signal along the way, if errors are produced, the device needs to send the signal again to get through, this applies for anything that is wireless. A wireless device and a hardwired amplifier will respond much quicker and work more reliably than if both devices are wireless. An analogy we can use is if everybody is trying to walk through a doorway at one time, the doorway gets blocked.

Freeview Plus – What is it?


So we’re all enjoying Freeview with a new digital TV antenna, and all the benefits it has to offer like a 7 day program guide, setting up timers and multitude of channels (unfortunately some channels we’ll never watch), and just as we’ve mastered this, a new technology is just around the corner, in May 2014 it is set to start, Freeview Plus , oh on not something else I hear you say, so what is it?

Freeview Plus is a hybrid technology which mean it uses a mix if the internet and free-to-air digital TV, technically it uses HbbTV (Hyper broadcast broadband TV) technology. Freeview Plus has some benefits over the current Freeview and of the main benefit at the moment is the ability to catch up on TV show that was missed, as well as all the other features like setup “favorites” and an extended EPG (electronic program guide).

Current “catch up” shows are limited but can be seen here from Freeview here.


For those that already have TV’s connected to the internet, there some channels available to us like “iview”, “SBS on demand” and “Plus 7”, this is all internet TV through a smart TV or a “smart box” connected to a TV, another form of IPTV (internet protocol TV) we featured some time ago was in our blog about NAS systems and streaming DVD and Blu-ray movie that are stored on a hard drive in your home to all the TV’s in the house that are connected to internet, no need for a DVD or Blu-ray player any more.

There are other forms of internet TV that is already here and are all in some kind of set top box form, some we would of heard of and some not, and some of the suppliers are Telstra’s T-box, Apple TV, Google TV and iinet’s Fetch TV, so internet TV has been around for a while but Freeview Plus is a new technology and it will be interesting to see how it will take off and be accepted by everybody.

Will this mean another box, more remote controls? We hate to say but most likely yes, as this is a new technology, some current model smart TV’s may be able to download and use Freeview Plus but the most of us will need a new/another set top box to use Freeview Plus.


As technology evolves, gone are the days where only an antenna cable is run to the TV, now with the invent of the internet, the TV’s having the ability to connect to the internet and a NAS, and now Freeview Plus, running a data cable to each TV has become the norm not an option, some TV’s do come with wireless built in and that’s great where a data cable cannot be run to, but to ensure the TV receives to full bandwidth of the network a data cable should be run, when there are many devices connected via wireless like laptops, Ipads, Iphones ect ect, this can create congestion in the network and slow the wireless down, so it’s always best to run a dedicated cable to each device if possible and if building a new house, or shop that will use TV’s as a display, this now is a requirement as to stay up to date with technology.

Custom Audio Visual Solutions can install a new digital antenna and data outlet for Freeview Plus. We service Newcastle, Lake Macquarie, Hunter and the Central Coast.

Domestic FM Radio & TV Antenna systems


TV antenna systems are different for both commercial and domestic situations, so in this blog, we’ll be only looking into the domestic system. Although a lot of this information will also apply to a commercial TV antenna systems for clubs, pubs, apartments and units, we will talk about a small system in a house.


TV AntennasIn the last few year with the transition from the old analogue system to the new digital system, there has been a big fuss about “digital antennas” and how important it is that everybody has to change their existing TV antennas over to a new digital TV antenna to receive digital signals. Whenever the subject comes up, all that is heard is that it is necessary to change the antenna over to a new “digital” antenna, but is that really the case. There are only a few reasons to change your TV antenna over, and the main reason would be if the picture on the TV is breaking up (pixelating or freezing). Of course, if your TV antenna is about to fall apart then that’s another adequate reason, but who can honestly say they look at their antenna? We’ll get to some more reasons a little later on.


Has anyone ever looked around at different antennas installed? Have you ever noticed that each house has a different antenna, so why do they all look different? Nearly every house has something different on its roof. It all goes back to the analogue days, where we had a mix of TV stations on VHF as well as UHF, and your location in relation to the TV tower dictated how much TV reception was received so hence different TV antennas were used. So as a legacy of the good old days, a lot of houses still have the original antenna on the roof, not to mention the very tall masts to pick up TV stations from Sydney before all the channels were available in Newcastle. Today with only digital TV available, none of this is necessary anymore, but do you need to change your antenna over to a new digital antenna?

There are two different thought reasonings to this question; the first being is if the TV has a picture, why should I change the antenna over? You would think it’s not required and 99% of the time you would be right. This reasoning is valid but floored at the same time, for example, we have seen VHF antennas still picking up digital UHF reception. Every TV antenna will pick something up, but it all comes down to the amount of TV reception, the quality of the TV reception and the “digital errors” in the reception that the antenna is picking up. Also, all TVs have a threshold where the TV needs a minimum amount of reception to produce a picture on the screen, if it falls below the threshold or there are too many “digital errors”, that is when the TV will start to pixelate or even start saying “no signal”. As a result, nobody will know how much reception any antenna is picking up until a qualified antenna technician connects a signal meter to analyses the signal. But as a given rule – if there is a VHF antenna on the roof and regardless of the reception it is picking up, that antenna will need to come off, it’s not compatible with the new digital signals, and it’s not required for the Newcastle and Hunter areas.


Without getting too technical and from a technicians point of view, every old analogue TV antenna will need to come off and be replaced with a single UHF TV antenna for many reasons. The main reason is compatibility with the digital TV signal. Radio Frequency signals can do funny things including interfering with each other so to eliminate any external interference in any signals; only one antenna should be on the roof to minimise this effect. If another antenna is still connected it can still pick up other signal and it does not have to be RF signals to create problems, other problems can come from things like rust on any of the connections and even a connection done poorly will create problems too. Trees, hills and other building can be a problem too, this can be a matter of just relocating your antenna to a different part of the roof, or possibly having to raise the antenna higher on a mast to get over the problem, or even just point the antenna to a different tower. One thing that is easily overlooked is the coaxial cable and the splitter. If the cable is over 15 years old, there is no doubt that it will need to be replaced, but also the coaxial cable that is attached to the antenna will need to be replaced much earlier as the sun plays a significant effect on its effectiveness over time. All the coaxial cable we use are all UV treated, but even this will only extend the life for a period of time, if any installer tells you that their cable will last forever, thank them for their service and kindly ask them to leave, no cable will last forever when exposed to the sun.


Other problems can come from things that are out of your control, which is the transmitter tower. In the middle of 2013, we come to a home in the Charlestown area, previous to us arriving they had another antenna company there that could not find the problem. The antenna was pointing directly to the tower, and we could see the tower directly, the TV was still pixelating, the installation looked good except there was a lot of digital errors coming up. After talking to the television station’s technical engineers, we found out the errors on our meter was coming from the transmitting tower. After the transmitter was replaced the customer was receiving the channel correctly as if there were no problem at all, we also found out that we were the only antenna company in Newcastle to have called the station to see if there are any problems.


For views that cannot pick up TV reception with a TV antenna, we have a solution for you. We can install a satellite dish to pick up TV station, (like Foxtel) but this service is only available to views that are outside the digital broadcast area (there are no monthly fees like Foxtel).


As a conclusion, you can see that TV antenna problems can develop from anywhere at any time, and multiple problems occurring at any one time is very common as well. Because the industry is not very well regulated, there are a lot of companies that are running around that are ill equipped to handle many of the digital TV antenna problems we encounter that we have listed here. So, as a result, we’ve seen many installations completed poorly. So if you want quality service, and the job is done right the first time, we are the only company you will need to call.

Screen calibration and new technology part 1

Different screen technologies

With technology changing at a very accelerated pace, screen technology is also changing. Some of the technology still with us is LED, LCD, DLP and LCoS in projectors, LCD/LED in flat screens. It was said that depending on what was mostly watched will dictate what the best screen technology was to use. As technology changes, we now only really have is LCD/LED, though other display technologies are still available like plasma at the time of writing this blog, as plasma is phased out, new technologies are always being developed.


All previous technologies use gases and chemicals to create colours, but the newest screen type available at the moment is OLED, and to put it in its most basic form, the display use ‘organic’ components. Basically how it works is when electricity is applied to the organic component they start to glow, but as with all new technologies, there is drawback.


As OLED is the new kid on the block, we have found that there are some drawbacks to this technology, but it’s nothing that can be overcome with some TLC. By default OLED is a less efficient technology then others are in regards to light output. The colours used for most TV screens are usually red, green and blue, the primary colours. But to overcome the problems with light output from the display, current manufacturers have come up with very different solutions. LG, for example, has added a fourth colour being white to overcome this. Samsung still only uses RGB but have made certain pixels (the millions of little individual colour squares that make up your screen) physically different sizes. For example, the colour blue is not as efficient as the colour red so Samsung has made the colour blue pixel twice as big as the red colour and green is a tiny bit bigger than red as well. It was also said that the blue pixel over time would reduce in output, try finding this kind of information out from the retail stores.
