Does the HD-300 in Placeshifter mode still use the SageTV Transcoder process?

Does the HD-300 in Placeshifter mode still use the SageTV Transcoder process? My system resources are some what limited with still having MVP's, but I was wondering if using the HD-300 remotely will cause extra load on my system. I know using the PC client uses too much.

Thanks in advance!

Anything that involves connecting over the Internet necessarily requires transcoding.

What if I setup a VPN tunnel between routers. At that point, it will appear as if the HD-300 is local and as such, shouldn't transcode the video. I only wonder how bad the content would be at that point. Has anyone tried this?

Abysmal to unwatchable unless you have really, really, really fast pipes. An OTA broadcast can be ~20Mbps. Really fast home internet plans usually have ~5-10Mbps upload rate. The bandwidth is just not there to transmit the video without transcoding it to a lower bitrate.

Thanks for the info.

HDHomeRun box takes OTA signals tunes the channel and sends the information without code change over 100 megabit Ethernet without a problem because the information is expanded at the video point which is your computer/video card. If this data was decompressed in the HDHomeRun box it would be impossible to send.

So, in effect your computer CPU and software does all the work. If you have good hardware in your video card (like an ATI 5750) it can do the work.

A one hour recorded HD show on the SageTV can amount to 4-7 Gig of recording space (expanded data). To send this recorded data to another point over ethernet may cause a problem on some home networks that are slow.

If you connect your 'what ever box' to the HDHomeRun ethernet, you can watch the show 'live' without a problem, but you will not be able to timeshift and loose the great value of a PVR.

All true but completely irrelevant to the discussion, the server doesn't do any decoding, the playback device does the decoding.

The data is stored in it's original compressed format on the hard drive. 19.2Mbits/sec * 1byte/8bits * 3600 seconds/hr / 1024 Mbytes/Gbyte = 8.43 Gbytes for one hour.

Uncompressed (what you're calling "expanded data") takes between 300 and 600 Gbytes per hour of HD video.

If you connect your 'what ever box' to the HDHomeRun ethernet, you can watch the show 'live' without a problem, but you will not be able to timeshift and loose the great value of a PVR.

Not over the internet.

agree, not over internet, just local lan
