Epson 2250 Projector with Fire TV Stick and Sony AV Receiver



This video shows how to remove the Android TV stick in the Epson 2250 projector and connect a Fire TV Stick.  You can remove the Android TV stick, and sell it with the additional remote that comes with the projector to recoup some of the projector purchase price.  The Fire TV Stick remote can turn the projector on and off, and the Fire TV Stick remote can control the volume on the Sony AV receiver.   Also, the video goes over some audio considerations.  The projector was placed on the AV receiver for the purpose of creating the video.  The projector should not be place on the AV receiver when powered on so proper heat venting can be maintained.

Free 4K Using an Antenna: HDHomeRun vs. ZapperBox

ATSC 3.0 will make 4K content reception using an antenna possible, and it continues to be deployed across the United States.  In addition to a higher resolution, the new standard will make other visual and audio improvements possible.  Baltimore, Syracuse, and Buffalo are the latest cities as of the writing of this blog post to be making final preparations to have ATSC 3.0 services.  With the addition of these three cities, approximately 25% of United States viewers will have access to ATSC 3.0 according to Advanced Television Systems Committee, Inc.  The areas that currently have ATSC 3.0 available and those that will have it soon are shown below.

ATSC 3.0 Tuner Options

A compatible tuner is required to receive ATSC 3.0 broadcasts.  One option is to purchase a new TV with an internal ATSC 3.0 tuner.  A better option may be to purchase an external ATSC 3.0 tuner box for those who want to use DVR software to record TV content.  SiliconDust's HDHomeRun Connect 4K can be purchased now, and the ZapperBox can be preordered now.  The ZapperBox M1 will be available around September 2021 according to the manufacturer.    

HDHomeRun Connect 4K

The table below summarizes the key features and differences between these two products.  The table includes the features of the ZapperBox that are reported by the manufacturer to be included when the first model ships and future software updates.  The ZapperBox manufacturer indicates that software updates after the product is first available may expand its capabilities.

Audio Considerations

The HDHomeRun Connect 4K requires additional hardware that supports Dolby AC-4 audio in order to use the ATSC 3.0 tuners.  A sound system that supports Dolby AC-4 is not required if a product such as an NVIDIA Shield which can decode Dolby AC-4 internally is used with the Connect 4K.

Fire TV Stick DVR Viewer Using MythTV Leanfront Example Installation Steps

This blog post explains how to install MythTV DVR software on a Fire TV Stick and shows it being used to view live TV and a recording.  In this setup, I am using a CableCARD tuner which generally allows MythTV to be used to view and record encrypted Comcast cable channels other than premium channels such as HBO.  As explained in the video, another computer is also needed to run MythTV Backend.  The video editing software I use causes the video to appear slightly jerky, and the actual video on the TV from the Fire TV Stick is smooth without the skips shown.  This Fire TV Stick is compatible with HD content, but it is not compatible with 4K Ultra HD content.
