Here is a question I just got from Richard to help with his progress in next version of the avx-1 sw.
169time requests feedback.
This request is specifically for those 169time.com AVX1 users that can
receive and record both OTA and DirecTV, including those that get OTA that
is synthesized by a Dish 5000 modulator or Sencore modulator, and actual DTV OTA broadcasts. 169time would appreciate user feedback as to how the AVX1 processing of OTA compares with AVX1 processing of DirecTV HDTV satellite based signals.
Although the AVX1's primary function is to enable digital recording of HDTV
from satellite, it can also be used to view and record a single OTA based
channel. This is useful in that it allows selection of a particular program
to be viewed on the JVC deck's outputs when more than one program is being broadcast on the same DTV channel, however this is not the reason for requesting the feedback.
It is likely that to get the information needed here, additional analysis by
the AVX1 user would be needed, by using the AVX1 in a way that is similar to the way that is used to recording HDTV from DirecTV, but with the DTC100 (or PSHD105) tuned to a digital OTA channel, either or both from local reception of digital television or the output of the Dish 5000 modulator.
It is not necessary to record the signal to provide this feedback. Instead
of recording, use the JVC deck's component YPrPb and audio outputs to
monitor the signal, and check it periodically for any anomaly while the STB
is tuned to a OTA DTV channel.
Either a SD or HD OTA DTV signal can be used.
When doing this be sure that the AVX1 is actually engaged. That is, ensure
that the JVC deck has selected the AVX1 as the ILink input source, and that
the DTC100's front panel light is not flashing, thus ensuring that the
DTC100 is not selected as the digital firewire source for the deck.
The ultimate question is how long the AVX1 and deck together keep a stable signal coming out of the JVC deck's outputs. If several OTA sources are available, the experiment can be conducted for each OTA source, to determine if there is any difference.
The reason why 169time is requesting this feedback is that this will help
169time clarify the success or problems encountered within the user base of AVX1 application. 169time understands that improvement is desirable for the success rate of satellite recording. An update for the AVX1 is in
development. The AVX1 uses a very similar process to handle OTA recording as is used for satellite recording. By determining the success rate for OTA DTV with the AVX1 through this request, 169time will be able to understand the rate of proper operation of those sections of the AVX1 process that are common to both OTA and satellite processing.
