FiOS provides not just SD (480p) versions of the analog signal, but also HDTV (720p/1080i) versions of all the OTA channels, as well as all the subcarrier OTA channels in SD (e.g. WCSN, formerly The Tube on myPHL, ABC News, NBC Weather, etc.) WGN Superstation, Bridges, Telemundo, Univision, WMCN, and the EXPO channel are also provided in SD (480p). The Weather Channel and Weatherscan are provided in SD digital, as is NPTV in the North Wales / Lansdale area. All of the Music Choice and URGE Music "radio" stations are also included in the "Local Plus" digital TV package. These are all delivered in Clear QAM (256).
However, as of approximately 6 weeks ago the audio portion of the digital MPEG-2 transport stream (QAM) for the WGN Superstation and The Weather Channel has stopped working.
(It had been working before then since the FiOS TV service was first made available here; approximately a year.) I haven't yet performed my own audit of the transport stream to determine if the audio portion is merely corrupted or completely absent. Sound still works on the analog versions thereof. Although, when Verizon runs a FiOS ad on The Weather Channel, sound does work then.
Resolving this issue with Verizon has been laborious to say the least because they want coerce all subscribers into renting their set-top cablebox as a loophole to regulations on pricing for the content itself; I've had to argue against countless lies that "you don't get digital, just analog" and "the problem is with your tuner" (although I have confirmed this problem with several different QAM tuners).
Has anyone one else had this problem or managed to resolve it? Any additional information or insight would be appreciated.
p.s. I was told by one Verizon representative in their "fibre solutions" (technical support) that they add a "broadcast flag" into the transport streams. I know that the PMT header in the MPEG-2 TS they send is so padded with information that it spans multiple packets (very unusual for the format). Presumably this is read by their receiver box to perform actions such as delete recorded shows after a certain date or to prevent fast-forwarding in recorded shows, which other users have complained about.
p.p.s. Verizon technical support centers in Texas, Illinois, and Florida use the Slingbox
to view channels in your locale. This is why they ask you "what channel?" for a particular broadcaster, even if you're trying to articulate a particular (digital) QAM frequency MPEG-2 transport stream. The multiple conversions from QAM to set-top box to Slingbox appears to mask / obscure the issue I need them to troubleshoot.
