Overview
This audit template is built for cinema teams that handle encrypted Digital Cinema Packages and the KDMs that unlock them. It walks the reviewer through the full control chain: identifying the audit location, screen, and date range; listing the DCP titles and ingest dates in scope; confirming delivery records and chain-of-custody; verifying KDM receipt, target server match, and validity window; reviewing content-server access logs and credential controls; and checking that expired content has been removed or archived correctly.
Use it when you need to prove that a title was received, ingested, authorized, and kept under control through playback. It is especially useful for multiplexes, premium-format screens, and any site that handles frequent encrypted bookings with tight showtime windows. The template also helps when a distributor disputes receipt, when a KDM fails to open, or when management wants a documented security review of the content server.
Do not use it as a projection-quality checklist or a general auditorium inspection. It is not meant to cover lamp alignment, sound calibration, seating, or building safety. If the issue is a missing package, wrong auditorium target, expired key, shared login, or leftover content in storage, this template is the right fit. If the problem is a physical facility hazard or a fire-life-safety issue, use a separate inspection focused on those controls.
Standards & compliance context
- This template supports documented control and traceability practices consistent with ISO 9001-style quality management and internal audit expectations.
- Access restriction, credential management, and log review reflect common information-security and asset-control principles used in regulated environments.
- If your cinema operates under distributor security requirements or studio delivery terms, this audit helps demonstrate custody, authorization, and expiration control.
- Where site policy requires it, retain records for chain-of-custody, KDM handling, and corrective actions in a controlled document system.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
What's inside this template
Audit Scope and Asset Identification
This section defines exactly which location, screen, titles, and server are in scope so the audit cannot drift.
- Audit location, screen, and date range documented
- DCP titles and ingest dates listed for the audit period
- Content server identifier and serial number recorded
- Inspection scope includes all active KDMs associated with the listed DCPs
DCP Receipt, Chain of Custody, and Delivery Confirmation
This section proves the package arrived, who handled it, and whether any delivery gaps need escalation.
- Delivery confirmation or receipt record available for each DCP
- Receipt record includes sender, delivery date/time, title, and package identifier
- Chain-of-custody log shows who received, ingested, and approved the DCP
- Any delivery discrepancies or missing packages escalated and documented
KDM Receipt, Validity, and Expiration Control
This section checks that each encrypted title has the right key, on the right server, for the right time window.
- KDM file received for each scheduled encrypted title
- KDM matches the correct content server and auditorium target
- KDM validity start and end times verified before playback
- Expired or soon-to-expire KDMs identified and escalated before showtime
Content Server Access Control and Security Logs
This section verifies that only authorized users can touch the content server and that activity is traceable.
- Content server login access restricted to authorized users only
- Unique user accounts used instead of shared credentials
- Access log reviewed for unauthorized access attempts or unusual activity
- Administrative password or credential rotation current per site policy
- USB ports, removable media, and external ingest paths controlled per policy
Expired Content Removal and Storage Hygiene
This section prevents stale titles and old keys from lingering in active storage or show schedules.
- Expired DCP content removed from active playlists or show schedules
- Expired KDM files deleted or archived in a controlled location
- Storage directories free of orphaned, duplicate, or unidentified content packages
- Removal actions documented with date, operator, and title affected
Exceptions, Corrective Actions, and Sign-Off
This section captures deficiencies, assigns ownership, and closes the audit with accountable sign-off.
- All deficiencies recorded with title, severity, and corrective action owner
- Any critical item failures escalated to management and documented
- Inspector signature captured
How to use this template
- 1. Enter the audit location, screen, date range, and the exact DCP titles and ingest dates you are reviewing so the scope is unambiguous.
- 2. Verify each DCP against its delivery confirmation or receipt record and note the sender, delivery time, package identifier, and any missing or discrepant items.
- 3. Match every scheduled encrypted title to its KDM file, confirm the content server and auditorium target, and check the validity start and end times before playback.
- 4. Review content-server access logs, confirm that only authorized users have access, and verify that unique user accounts and current credential rotation are in place.
- 5. Check that expired DCPs and KDMs have been removed, archived, or disabled according to site policy, then document every deficiency, corrective action owner, and final sign-off.
Best practices
- Record the exact content-server identifier and serial number so a KDM mismatch can be traced quickly.
- Treat a missing delivery confirmation as a control failure, not a paperwork issue, because custody cannot be proven without it.
- Flag any KDM that expires before the next scheduled show as a time-sensitive deficiency and escalate it immediately.
- Use unique user accounts on the content server and avoid shared credentials that make access logs meaningless.
- Review the access log for unusual activity such as after-hours logins, repeated failed attempts, or unexpected ingest actions.
- Remove expired or orphaned content from active playlists and storage directories so stale titles do not get scheduled by mistake.
- Document every corrective action with the title affected, the owner, and the date completed so follow-up is auditable.

Common use cases
Frequently asked questions
What does this DCP and KDM audit template cover?
It covers the operational controls around encrypted cinema content, not projection quality or auditorium maintenance. The template checks DCP receipt records, chain of custody, KDM validity windows, content-server access controls, expired content removal, and exception sign-off. It is designed to verify that a title can be received, stored, unlocked, and scheduled without avoidable security or playback issues.
When should this audit be run?
Run it on a scheduled cadence before busy booking periods, after new encrypted titles are ingested, and whenever a server or security process changes. It is also useful after a missed show, a failed ingest, or a suspected access-control issue. Many sites use it as a periodic compliance check and as a pre-show readiness review for high-value titles.
Who should complete this audit?
A projectionist, cinema operations lead, or technical manager usually completes the walkthrough, with management review for exceptions. The person running it should understand DCP ingest, KDM assignment, and content-server access controls. If the site uses outsourced technical support, the audit still needs local verification and sign-off from the responsible operator.
Does this template map to any specific regulatory or industry standard?
It aligns with general security and recordkeeping expectations rather than a single cinema-specific law. The controls support good practice under broader compliance frameworks such as ISO 9001-style document control, access management principles, and site security policies. If your organization has contractual studio requirements or internal SOPs, this template helps document that those controls were actually followed.
What are the most common problems this audit catches?
Common findings include missing delivery confirmations, KDMs issued to the wrong server or auditorium, expired keys still listed as active, shared login credentials on the content server, and orphaned DCP files left in storage. It also catches weak documentation around who ingested or approved a title. Those issues often cause showtime delays or make it hard to prove custody and control.
Can I customize this for a multiplex or a single-screen cinema?
Yes. For a multiplex, add one line per screen, server, and title so the audit can track multiple auditoriums in the same period. For a single-screen site, you can simplify the scope while keeping the same controls for receipt, KDM validity, and access logs. The template is meant to be adapted to your booking volume and staffing model.
How does this compare with ad hoc checks done by email or spreadsheets?
Ad hoc checks often miss one of the three critical links: receipt, authorization, or expiration control. This template forces the reviewer to verify each title against the delivery record, the KDM window, and the server access trail in one place. That makes it easier to spot gaps before they become a failed screening or a security exception.
What should I do if a KDM is close to expiring or does not match the server?
Record it as a deficiency immediately and escalate before showtime. The correct response is usually to contact the distributor or content provider for a replacement KDM and confirm the target server and auditorium details. Do not assume a key will work just because the title file is present on the server.
