Hello Skooter Blog readers. Today I talk about a Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6 (1080P HDMI Over CAT5E / CAT6 Extender Set – Black (2-Input / 1-Output)) acquired on DX – DealExtreme. This device serves to carry digital picture and sound over long distances using standard network cables, which are much cheaper than long distance HDMI cables, and are much easier to crimp.
The operation of Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6 is simple, simply connect the HDMI cable image generator and sound equipment at the transmitter, connect a network cable (UTP – unshielded twisted pair, cat5e cat6 egg) that goes from transmitter to receiver and receiver connect a second HDMI cable to the TV / Monitor will present the image.
My use for Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6 It is to make a slave point of Sky HD. I had already made slaves points with wireless transmitters and with baluns, but in both cases the transmitted image was SD, with video quality compost. Once migrated for a Sky TV with high definition channels and changing the decoder for HDMI output, I decided it was time to purchase a new solution, that allowed the slave point also receive high-definition pictures.
Notice that, if the generating device has only one HDMI output, using an HDMI splitter will need, like Splitter HDMI de 1 entrada para 4 saídas HUIYSHUN HDMI-400 HDMI v1.4 Full HD 1080p 3D (HUIYISHUN HDMI-400 3D 1080p Full HD HDMI V1.4 1 to 4 Splitter – Black + White (UK Plug / 100~ 240V)), of which I will speak in a future article. Do not forget to also purchase the HDMI cables will be needed, they are not included with the Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6. To transmit the remote control signal recommend Repeater / Extender Wireless Remote Control IR <-> 433MHz, to 200 metros Pakita PAT-433 (New 433MHz Wireless IR Remote Extender Repeater 200M).
The transmitter Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6 It has two HDMI inputs, then you can connect up to two sources simultaneously, but to alternate them you need to use a switch on the transmitter, which is not very practical. I ended up using only one entry, they only wanted to take the Sky image.
Both the transmitter when the receiver Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6 They are active, have multi-voltage power supply that must be connected to electricity for the whole work. This set uses um only after rede, unlike other models that use two cables. I opted for the model of a cable only because the reports are that these models are usually best. The explanation is simple: each network cable has 8 drivers, while an HDMI cable has 19 drivers. It takes more engineering to match 19 conductors 8 than 16, so the models that use only one cable usually have a more well-designed and robust circuit to the multiplexing / demultiplexing. Furthermore, less than half of the HDMI drivers use high bandwidth, most of the drivers are for signaling, then it is a waste to let a cable more just for them.
In my tests, the image and sound of Sky HD transmitted by Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6 He was perfect in the remote TV. I used cables that came close to the limit 50 meters that the product supports. Both cables cat6 as cat5e cable worked perfectly. It is likely that greater lengths support cat6a, but did not go beyond the limit with neither.
A negative point Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6 and than, contrary to what the title says the DX, He was not able to transmit images 1080p. I auditioned with the output of my WD TV Live and the image of my Mega Drive connected to SCART Video Converter + HDMI to HDMI (SCART + HDMI to HDMI Video Converter – Black). In both cases, only worked when I downloaded the resolution to 720p. Turning transmitter and receiver with one less short network cable 2 meters, 1080p signal passed, but still was failing. So do not recommend this device to anyone who wants to transmit signal in 1080p.
In the case of Sky HD there was no problem, because there are not channels broadcasting in 1080p, only 480i, 720p e 1080i. Most HD channels is 1080i resolution and that the Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6 works perfectly. 720p has only ESPN, if I remember correctly, and that the resolution Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6 also it worked perfectly. The SD channels 480i also work perfectly. I think it unlikely that Sky will broadcast in 1080p in any near future.
My conclusion is that the Conjunto Extensor HDMI sobre cabo de rede Cat5e / Cat6 You are not able to handle the bandwidth required for 1080p signal, but it is sufficient to lower the signal bandwidth of 1080i, 720p e 480i. For those who will only use the Sky, is an appropriate solution. A DX should be more careful to assign attributes to your products, because there is no information in that it supports 1080p product box, and there is no indication of who the manufacturer. Just bought this also another da whole brand LINK-MI, which theoretically supports 1080p, to make a second point slave. I will speak of it when you get.
