The Copy Protection Information file is a binary file used for processing copy protection systems such as CPPM. It is composed of one file header followed by one or more information records of different types. Each information record is used to convey a different type of information. A copy protection mechanism may require different types of information records. The contents of the Copy Protection Information File header are shown in figure 6-1.

Table 6-1. Copy Protection Information File Header Contents

After the Copy Protection Information File Header are one or more Copy Protection Information Records. Each Copy Protection Information Record is a multiple of 16 bytes in size and starts with a 16 byte record header that is used to identify the type of record. Table 6-2 shows the contents of the Copy protection record Header.

Table 6-2 Copy Protection Information Record Header

HdrLbl – Record Label Header – This field contains an alphanumeric identifier used to identify the type of information store din the record.

HdrVer – Record Version – This field contains a version number for the record. This field in combination with the Record Label Header is used to identify the actual content and format of the information stored in the record.

LEN – Record Length – This field contains the total number of bytes in the record including the Copy Protection Information Record Header.

In this version of the specification there are two types of Copy Protection Information Records shown below,

Disc Parameter Information Record – Contains physical parameter information for the disc being described

CPPM Information Record – Contains information specific to Copy Protection for Prerecorded Media (CPPM).

Disc Parameter Information Record

The Disc Parameter Information Record contains physical parameters for the disc. Table 6-3 contains information on the Disc Parameter Information Record.
