PRB: Duplicate Channels in IPG (815445)
The information in this article applies to:
- Microsoft TV IPG 1.0
- Microsoft TV IPG 1.5
SYMPTOMSWhen there is a change in the channel line-up, Tribune Media
Services (TMS) keeps the old channel information and adds duplicate channel IDs
that contain new information.
Note After 60 days, TMS removes the duplicate channel IDs.
CAUSEThis problem occurs because IPG versions 1.0 and 1.1 do not
support filtering TMS data by using a specified expiration date and a specified
effective date. This causes Import Job to import all duplicate channels.
Microsoft IPG 1.0 and 1.1 Server do not support duplicate channel IDs that TMS
delivers.RESOLUTIONFor users of IPG
1.0 and 1.1 Server, the customer or the Microsoft deployment team can use a
Custom line-up when the channel line-up changes or apply the workaround patch
to the TMSLineupLoader.dll.WORKAROUNDFor IPG version 1.0 and 1.1, you can avoid using a Custom line-up by applying the patched DLL (TMSLineupLoader.dll). To do this,
follow these steps:
- Quit all programs.
- Rename the TMSLineupLoader.dll file. This file is located
in the MicrosoftTVInstallPath\Microsoft TV
Server\Components folder. Change the name of this file to
TMSLineupLoaderOriginal.dll.
- Copy the TMSLineupLoader.dll file from the source depot
(//depot/mstv_pss/projects/IPG/kb_binaries/TMSLineupLoader/TMSLineupLoader.dll)
to your MicrosoftTVInstallPath\Microsoft TV
Server\Components folder.
- Delete all records from the line-up table in the EPG
database.
- Run Import and Export jobs.
STATUS Microsoft has confirmed that this
is a problem in IPG version 1.0, and 1.1.
This problem was corrected in IPG 1.5 Server.
MORE INFORMATIONThe TMS duplicate-channel process that is described in the
"Symptoms" section is a known TMS process. Third-party products that use TMS
data support this process.
