Live video for DATV or streaming

Introduction
Live video for amateur TV or streaming (local or internet) has progressed considerably since I last looked a few years ago. The big change is NewTek's NDI, an open standard for video streaming released in about 2015?. NDI is for fast streaming video over ordinary wired or wireless networks with little lag and compression of a variety of devices and operating systems at relatively low cost.

Newtek NDI software https://www.newtek.com/downloads/  All Newtek software without having to request it.

NewTek NDI Camera Apple or Android app Turns an Apple or Android mobile device camera into an NDI source. $20 for app but can be used on multiple devices connected to same Apple/Android account. I have tried it with an iPhone and iPad and it works very well. Very good camera and image quality. As for low-cost cameras, an old iPhone with no sim card and possibly an iPod Touch may be an option, costing maybe a couple of hundred dollars. This is quite reasonable for a full HD clean…

Telstra EasyMesh router and WiFi extender; wired network switches too.

Introduction We have moved to a two-story house with no network cabling. I need both full wifi coverage and wired network for the devices that don't have wifi. The solution is remarkably simple, the new Telstra EasyMesh router gen 2 and WiFi extender gen 2, with wired switches connected to either or both the router and extender. Using the WiFi Easymesh extender with a network switch attached allows non-wifi devices to connect to the router via wifi. A very neat solution.

Easymesh Wi-Fi CERTIFIED EasyMesh™ is a new WiFi standard for mesh wifi available in 2019. Previously, mesh wifi was proprietary, not standardised. Telstra is one of the first to offer Easymesh devices in the world. Easymesh consists of a router and multiple extenders (access points or boosters), up to 4 with Telstra, that share the same wifi name and auto-switch between the 2.4 and 5 GHz wifi bands.

Wired switches too! Not obviously documented, but I discovered…

Perfect Home Theatre finally: Nvidia Shield, PLEX, SiliconDust tuner

Finally, a home theatre system that does everything and only one remote. I have been playing with home theatre and music for about 50 years and finally have a system that does everything I want without switching between multiple boxes and many remotes.

I can watch live TV, stream commercial services like Netflix, Prime or Stan, stream my own movie, TV show, music and photo content, watch catch up TV, such as ABC iview, SBS on demand and many others, and casting from IOS devices.

The system uses the TV/projector as an HDMI monitor and a theatre amplifier for sound making it easy to replicate across two systems, one in the lounge and the other in the sunroom. As such, both have the same interface, getting around the nightmare of different interfaces to remember.
The main hardware of the system: 4K Nvidia Shield TV Android media streamer.
