One of my greatest interrest is to explore how to transfer data. It doesn’t matter if its ethernet, fibre, coax or wifi.

This article will give you an understand of how to transfer data through everything.

 

Air:

Wifi is ideal for long distance links with line of sight. Ubiquiti provides some really nice antennas for this purpose. AirFiber is interresting if you are professional and needs gigabit, but the Nanobeam AC/NanoStation M5 are also interresting units. You can provice really great throughput (450 mbit) utilizing these units.

Another solution for air-transmission also exists Freespace Laser Optics (FSO). The solution consist of 2 lasers and 2 photo-sensors. It’s quite fast but requires that the lasers and photosensors are in line of sight at all times. The solutions are expensive, and is really sensitive to fog, snow and rain.

Coax-cable:

Until reasently I didn’t even consider this as an option. I thought it would require too expensive equipment, because this actually is what cabletv-providers/coax-isp’s does. A new MoCA-protocol has apparantly been released – and bandwith goes up to 800 mbit through a standard antenna cable. And most surprisingly it’s even affordable. I noticed today, that Triax is making a product for 220V.

Electricity-cable:

Powerline has become more and more popular. Zyxel is the market leader and is making some interresting units. Especailly the MIMO unit PLA5405 should perform really well..

Fiber-cable:

Fibre-cable is known to be the most stable link. Fiberconverters easyly provides 1 gbit with no problems.

Feel free to comment, if you know other ways of transfering data. Portable-devices USB drives, Floppydisc, cd-roms etc. are not accepted as a suggestion.

I’m so happy. I wrote in middle of marts to Elgato’s support about that they with small effort could create a dvb-c product for the european market based on the 4sat-tuner they already have. And now 1 month later they released the new product Elgato EyeTV Netstream 4C. I’m so amazed. I will update this thread later on… Its fantastic!

I preorderd the HDTC-2EU for 2 years ago. Sadly the delivery-time got delayed and delayed. 2 weeks ago I got a mail from Proshop, which was telling me that they had given in receiving the unit. I told I didn’t expect them to deliver it. Because I was aware Silicondust didn’t release the unit yet. Anyway the cancel’ed my order.

I started googleing for alternatives and found out that Elgato had a solution really close to the HDTC-2EU named Elgato 4Sat – only difference was that the Elgato tuner was DVB-S/DVB-S2. Built into Elgato 4Sat was the h264-encoder. I therefore decided to write them a mail in hope to releas a 4Sat DVB-C version for the european market. I got a positive response, so hopefully they will do some magic. 🙂

EDIT 16/04/2015:

Fantastic news ! Elgato have just released a dvb-c tuner of the 4Sat-model as I wrote they should do. Now I’m just awaiting that they arrive in the danish shops – and it looks like being fairly soon: https://www.fcomputer.dk/hardware/grafikkort/elgato/eyetv-netstream-4c.html . The model is named Elgato EyeTV Netstream 4C – read all about it here: https://www.elgato.com/en/eyetv-netstream-4c – It’s amazing, that they actually did what Silicondust couldn’t do for years in just 1 month. I’m so happy I contacted their support-team.

 

I have been going deep into the transcoding progress – and have figured out that Fujitsu actual have been creating some nice transcoding LSI chips. Where the MB86M02-chip would be the most interresting chip. It seems that Fujitsu started a new joint venture with Panasonic named Socionext – which has the purpose of selling the invented hardware. You can read about the chips here: http://www.socionext.com/en/products/imaging/h264/ . So it seems that theirs no reason not to hope for a dvb-c network tuner with transcoding and dlna-support in the comming months/years.

But…. something has actually already happend. It seems that the newest sat-reciever (which supports dvb-c extension hards) from VU+ actually support hardware-transcoding. The modelnumber is named VU+ Duo2 and is quite pricey – and sadly the transcoding streaming functionality is not that well described.

Eventhough it seems possible that the device would fit my needs.. I would like to know some details before buying it. First I would like to know if it can transcode 2 streams at the same time. Second I would like to know how to tell the tuner which tuner to choose, if 2 tuners are installed (maybe a url-parameter can be specified?). I have been looking everywhere on google to find this – and it seems noone actually have been writing anything about this. It seems the URL is just an identifier-json-string for internal VU+ Duo2 usage.

So if you know something about how streams are handled through the VU+ Duo2 then please let me know 🙂

Eventhough I havn’t been able to get an officially deliverydate from Silicondust it seems that their design Company by mistake reveals the secret of when the HDTC-2EU will be comming here: http://henderson-design.com/project/hdhomerun-plus-hdtc-2eu/

I preordered my unit at Proshop may 2014 with a deliverydate stated to be 5th of september 2014. When I reached  1st of september I got a call from Proshop saying that the delivery wouldn’t be in time – and the new deliverydate would be in march. I contacted Silicondust-support, which told me, that Proshop shouldn’t have made the unit available for preorder – and they didn’t have any estimated delivery date yet. In hope to get a deliverydate for European stores I decided to ask in the HDHomeRun-Facebook-group – sadly noone have ever replied, eventhough we were 3 guys asking. Hopefully henderson-design’s delivery date is be trusted, which Means it will be an real awesome Christmas Present.

I was asked to investigate a weird issue with an Apple Mac Book-laptop, which was loosing connectivity to the dd-wrt network. After some investigation I found that iPhone 4 (and 5) had a known issue with loosing connectivty with dd-wrt routers. The fix however was to tweak 3 settings. Under advanced settings:

Beacon Interval should be lowered to 50 ms from 100 ms.

Fragmentation Threshold should be lowered to 2304 from 2346.

RTS/CTS Threshold should be lowered to 2305 from 2347.

These tweaks solved the issue – and now the apple products are all happy on the WDS-wifi-network.
