<br>
The original Comcast DTA only had an RF (NTSC) output,<br>
limited to SD content and intended as a cost optimized<br>
solution for those that were still using SD TVs in areas<br>
where Comcast was turning off analogue. It did not have<br>
guide or interactive (VOD) capability.<br>
<br>
The newer HD-DTA has both an RF (NTSC) output, capable<br>
of doing what the older DTA did, and also has an HDMI<br>
output for newer digital TVs. It is a cost optimized solution<br>
for basic HD content. At entry to service, it also did not<br>
have any guide, although there was some talk about<br>
basic guide capability (I do not know if they managed to<br>
roll that out), and it also does not have interactive<br>
capability.<br></blockquote><div><br></div><div>My new DTAs have a guide capability.<br><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

They are used by some as "second TV" boxes, although<br>
for those that want cheap, and do not subscribe to the<br>
highest tiers of service, they are an option for anyone.<br>
<br>
As neither have out of band tuners, they get their<br>
information in-band (the channel mapping is done via<br>
SCTE 65), and use SCTE 52 encryption rather than the<br>
more advanced CableCARD capabilities (SCTE 52 is<br>
considered "good enough" for content without strong<br>
protection requirements).<br>
<br>
With the X1 platform, Comcast is moving away from<br>
the DTAs for second TVs and moving to even dumber<br>
(and presumably still cheaper) device, the Xi3, which<br>
is basically just a front end player for the X1 gateway<br>
which does all the heavy lifting.<br>
