ohjelmanvaihto

Ohjelmanvaihto is a Finnish term describing the act of switching or exchanging a program. The term combines ohjelma (program) and vaihto (exchange, switch) and is used to refer to planned or operational transitions where an active program is replaced by another, either temporarily or permanently. The concept appears in different domains, including media scheduling, information technology, and process control.

In broadcasting and media management, ohjelmanvaihto refers to the scheduled or urgent transition from one program to another. This can occur when a program ends and a different show begins, during a break in programming, or when urgent news or emergencies require a rapid switch. The process typically involves coordinating with playout systems, updating Electronic Program Guides (EPG), and issuing announcements to viewers or listeners to minimize disruption.

In information technology and software deployment, ohjelmanvaihto denotes swapping a running software service or application for a new version or alternative program. This includes planning, version control, and deployment strategies that aim to maintain service continuity, such as blue-green deployments or canary releases, as well as testing and rollback procedures.

In other contexts, such as industrial automation or event operations, ohjelmanvaihto can denote changing the program logic or control software within a system, or substituting operational procedures or schedules.

Key considerations across contexts include minimizing downtime, ensuring compatibility, communicating changes to users, and maintaining records of versions and rollback options. See also program switching, deployment, blue-green deployment, scheduling, and playout automation.
