This is a repost from thread "Orlando Brighthouse and clear QAM problems. Let me apologize for starting a new thread and posting there. I now see that this forum works as a continuous thread on all issues related to BH in Orlando without a hierarchy. If there is a moderator could you please delete the erroneous thread if that is appropriate.
I do have one question on the forum. How do I read this thread starting with the newest first? The default is to start with the oldest which are from 2004 and I am interested in what is happening now.
EDITED REPOST FOLLOWS
I have been communicating with Brighthouse for many weeks now and seem to be getting nowhere but more and more frustrated.
According to the FCC and ATSC regulations I have read, my understanding is that BH is supposed to include clear (unscrambled) QAM transmission streams for all channels that are available OTA in the same area as part of their licensing agreement. They do this for the Orlando area but there are several problems and I can't get anywhere with BH since they won't let me get past the customer service reps who do not seem to have the technical knowledge to handle these types of problems.
Basically the problem is that the virtual channel table (VCT) and Program Service Information Protocol (PSIP) metadata is being modified by BH with introduced errors into the BH cable channels causing problems for TV tuners. The problems are worst on virtual channels 6.1 (WKMG) and 68.1 (WUCF). The PSIP for 6.1 and 68.1 are completely missing about half the time on BH. On 9.1 WFTV OTA I have at times seen the EPG metadata missing but the correct VCT is always there. BH deletes the whole PSIP in this case and virtual channel is then untunable. When this happens my TV tuners don't have the necessary information to connect the virtual channel 6.1,9.1, or 68.1 with the correct physical channel. By searching for the missing programs I most often can find them on the upper virtual channels, 70's and 80's, without any PSIP data. Since I can also receive these channels OTA I have set up 2 identical TVs side by side. From this I can verify that the OTA VCT and PSIP data are absolutely correct and simultaneously that the BH cable channel data are corrupted. I have verified these problems with others in my apartment complex. They are also evident at the local YMCA which has TV on the exercise machines with BH cable.
After complaining many times BH sent a tech to my apartment. He could find nothing wrong with the physical signals on the BH channels but after seeing what was happening agreed that there was definitely a data problem. He stated that this was above his level and understanding and would have to fill out a report to get the problem to the engineering staff. Results - nothing. When I email BH again I get a canned answer "we are sorry you are having signal level problems and will schedule a technician for a visit to correct .....".
I am convinced that the problems are not signal level problems. And the technician agreed. They are being caused by the channel multiplexing equipment and/or operating staff at BH. This is the equipment that gathers all the digital program streams and multiplexes them into the physical channels on BH cable. Since they are changing the virtual channel assignments (TVCT to CVCT) to properly meet there own cable channel assignments, they are necessarily modifying the PSIP and VCT. This is perfectly in compliance and acceptable if they do this correctly. They repeatedly and consistently DO NOT.
I am a retired engineer with experience in digital communications (not cable TV). The customer service contacts I have communicated with seem to have insufficient knowledge about this level of technology. I feel I have explained the problems repeatedly to no avail and asked if I could just talk to an engineer. If there were some way to do this I feel that eliminating the middlemen and just minutes of communication at the correct level could clear up the statement of the problem from the customers view.
Since I have been unable to find any way to contact anyone at BH who would understand what the problems are, my level of frustration is going exponential. I am looking for advice from those with more experience with BH on how to proceed. Any suggestions or recommendations would be appreciated. I am especially interested in any other forums, blogs, or websites which address BH cable problems or complaints.
