As the STS I have taken the approach to allow multiple ways to get the new media onto the available TV’s throughout our Stake.
To start with I tested different devices: a Roku, Apple TV and 3 different mini android PC’s and found that the Rikomagic MK802 II New Generation Mini Android 4.0 PC Google TV Box HD IPTV Player
from amazon.com for $34.99 was the best (and cheapest) match for streaming the new media, so I got one for each of our ward buildings. The device plugs into a HDMI port on the TV and gets its power from a USB port on the TV. I installed the Gospel Library app for Android which now allows you to download the videos directly to the device (the 1 gig memory is ample to start with but you can upgrade with a micro sd card) and if you happen to be in one of the classrooms with good internet service it streams from the app perfectly. On the opening screen I placed bookmarks to lds.org, and the Come Follow Me page which allows easy access to the websites. Also the advantage that you need to make sure they have is the ability to have 2 separate USB ports. One is used for an optical mouse (I only had to purchase one as there were 3 hanging around in our FH Library) an onscreen keyboard comes up when you need to type, and the other USB port is used for a flash drive so the teacher can download the content from home and bring it to class. I only had one building with an older flat screen TV that I had to buy a plug in USB power supply for. The device runs similar to a windows pc and the navigation through the file manager or to the internet is very smooth, and if you have run the Gospel Library app for Android you’re right at home. http://www.amazon.com/gp/product/B0091UHMHO/ref=oh_details_o04_s01_i01
The next things I purchased were cables to hook up different tablets and phones to the TV’s.
For the Apple users I got the AmazonBasics 6.5-Foot/2-Meter Composite AV Cable for Apple iPhone/iPad/iPod
which is the 30 pin connector that goes to the RCA video and L/R audio for $22.99 http://www.amazon.com/gp/product/B004SBBDD0/ref=oh_details_o02_s01_i01
For the Kindle I got the Fintie Micro HDMI (Type D) to HDMI (Type A) Cable For Amazon Kindle Fire HD 7 Inch Tablet / Kindle Fire HD 8.9 Inch / Nexus 10 - 6 Feet Black
For the Android people I had to get two cables:Rocketfish HDMI to Micro HDMI Cable - 4'
And a Gold Plated HDMI to HDMI Mini cable, 1.83 m/ 6 ft 2 pack
I also got a HDMI cable
for each building at $5.73 for a 2 packhttp://www.amazon.com/gp/product/B0014Z29OU/ref=oh_details_o02_s01_i03
Last for the computer users a RiteAV - SVGA Monitor Cable with 3.5mm Audio - 6 ft.
By using the Mini-PC in place of the Roku, my Stake was able to equip the libraries with multiple ways to allow teaches to get the new digital media playing on multiple platforms; and at only a price tag of $83.21 (with Amazon Prime shipping is free). I have had all this in the libraries for a month now and given training on them in many of the wards (I like to follow the Stake after they do Ward Conferences) everyone is very happy to have ways to play the media and the only negative comment I have had is that we need a Mini PC for each TV with a HDMI port.
