CVT
Code Version Table. A method for staging DHCTs. The CVT is a table that contains information about download
channels and information to map client release software versions to specific DHCT types. The Broadcast File
Server (BFS) broadcasts this information once per second on every quadrature amplitude modulation (QAM)
frequency and on the quadrature phase shift keying (QPSK) frequency. If a DHCT does not have valid client
release software installed (such as new DHCTs), the DHCT searches QAM frequencies for software download
information. When the DHCT finds this information, it can begin to download valid client release software.
