In PID assignments, which table includes all programming/services with assigned PIDs for scrambled programs?

The correct choice pertains to the role of the Conditional Access Table (CAT) in the context of PID assignments in broadcasting systems. The CAT is specifically utilized to define and manage the association of Program Identifiers (PIDs) to their respective services or programs that may be encrypted or scrambled. This is crucial for services that require conditional access control, allowing only authorized users to access certain content.

In contrast, the Program Map Table (PMT) typically provides detailed information about the components included in a program, including the PIDs for the audio, video, and additional data streams related to that program. However, it does not specifically focus on the assignment and management of access rights as the CAT does.

The Service Description Table (SDT) provides information about the services provided in a transport stream, including their names and the PIDs of their PMTs, but it does not include direct handling of scrambled programs.

The Event Information Table (EIT) is focused on providing information about programming events, such as schedules and current showings, and does not serve the function of managing PIDs for scrambled content.

Understanding these distinctions clarifies why the Conditional Access Table is the accurate choice when identifying a table that includes all programming/services with assigned PIDs specifically for scrambled
