Live TV - Prestage Tuner & Transcode


Ceth

Recommended Posts

When the Live TV module is chosen by the user, the server should activate the first available tuner and begin transcoding the output without waiting for the channel selection (by default, it could select the last channel viewed by that user).  That way, by the time a program is selected, the stream is already flowing and the user only needs to wait while the buffer catches up to the moment the selection occurred.

 

When the user exits the Live TV module, the stream should be shut down.

 

This would create extra work for the CPU since it would be transcoding whenever the Live TV module is loaded regardless of whether a program is being viewed.  There could be a checkbox in the transcoding section of the server console that would allow or disable this feature.  For example, "Check this box to Prestage tuners".

What does that mean?

 

The goal is really to direct stream as much as possible so transcoding won't always be involved.

"Module" as in when a user enters the "Live TV" section of an app (as opposed to "Movies", "TV", "Videos" etc.)

 

Transcoding is still the only choice for many circumstances.  The combination of non-perfect network connections and flaky MPEG2 decoding is a problem for many (most) clients.  They don't support hardware decoding and aren't fast enough to properly do software HD decoding.  Even if they do work, playback is glitchy, halting, interlaced, etc due to inconsistent decoder quality and lack of features.
