How is the Software Downloaded to Set-Tops? 
The Code Version Table (CVT) is a table that contains download multicast 
information, as well as information to map application platform software versions to 
specific devices or groups of devices. 
The CVT method is the only download method available for Vantage set-tops. 
 
The Four Phases 
We have developed a four-phase download process. When you follow this 
download process as described in this guide, you will achieve consistent results, 
avoid system downtime, minimize subscriber impact, and avoid many common 
mistakes that occur when downloading client application software to set-tops. 
 
Phase One: Complete Pre-Upgrade Checks (See Chapter 2) 
When? You can complete this phase during normal business hours. 
1  Verify that the system is operating correctly by running the Doctor utility, 
reviewing the results, and correcting any issues found. 
Delete unused DHCT types from the system. 
3  Run the listCVT utility to identify unused files on the BFS. Then, remove the 
unused files from the BFS. 
Install the following onto the DNCS: 
 
Application Platform Release software 
 
New version of DHCT Resource file (settop.res) 
5  Correct any issues identified during Phase One. 
 
Phase Two: Test New Software (See Chapter 3) 
When? You can complete this phase during normal business hours. 
1  Create or modify the CVT test group(s). 
Load the new CVT image file(s) onto the image list. 
3  Download the software to the CVT test group(s). 
4  Verify that the test devices operate correctly.
