Films and other video content on discs, tape or other physical media

1. Scope and Applicability

This PCR governs foreground data production for physical carriers containing recorded films or other video content, including music videos, supplied as goods. It excludes blank reference products, audio-only media, software, playback equipment, online video, retail services, reproduction services sold without ownership of the resulting goods, and originals sold with all property rights. Manufacturing operations needed to produce the covered goods remain included. The official scope follows un-cpc-3-0-structure-2025 and un-cpc-3-0-explanatory-notes-2025.

The representative route is single-sided, single-layer DVD-Video replication from purchased polycarbonate and a purchased finished nickel stamper. Recording onto purchased DVD-R is a conditional alternative. NIST distinguishes molded ROM from dye-based recordable discs and shows bonded DVD construction (nist-sp-500-252-2003, sections 3.1–3.4). EPA supports molding, metallization, printing and packaging process decomposition (us-epa-life-cycle-cd-dvd).

For videotape, Blu-ray, Video-CD or another carrier, retain the category rules but instantiate the actual reference exchange, component bill, recording process, quality tests and waste streams before dataset use. DVD amounts and layer structures cannot be transferred to these media. A dataset covers one homogeneous carrier, edition and route; mixed portfolios require separate products and explicit aggregation weights.

2. Product Category Identity

Field	Value
canonical_pcr_id	pcr.metal-products-machinery-and-equipment.radio-television-and-communication-equipment-and-apparatus.films-and-other-video-content-on-discs-tape-or-other-physical-media
classification_refs	CPC 3.0: 47620; classification context only
covered_products	Physical carriers containing recorded films or other video content, supplied as goods
excluded_products	Blank media; audio-only media; software; players; online video; retail/reproduction services; originals sold with all property rights
representative_product	Saleable single-sided, single-layer DVD-Video of one declared edition
production_route	Physical-edition preparation; replication with a purchased stamper or conditional DVD-R recording; verification; packing
market_state	Finished readable recorded carrier at producer dispatch gate; packaging separately measured

3. Reference Flow

Field	Value
What	Supply the declared video edition on a readable physical carrier at the producer gate
How much	1 kg net recorded carrier; also report corresponding copy count and playable content duration
How well	Correct complete edition and language; declared format, compatibility and quality acceptance tests passed
How long or cycle	One production and release cycle; no assumed viewing count or archival lifetime
reference_flow_link	reference_video_dvd

Field	Value
Reference amount	1
Reference product flow	Prerecorded video DVD
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66
Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	Carrier/recording format; edition identifier; duration per copy; language; sides/layers; read-only or recordable state; compatibility and region restrictions; acceptance test and sampling plan; net mass per carrier; copies per sale unit; packaging bill and mass; route; master/stamper handover boundaries; site/geography/reporting period; yield/rejects; electricity delivery conditions; upstream coverage and exclusions

Required qualifiers shall be supplied in dataset metadata or linked production records. This mass-based declared unit supports manufacturing exchange; equal mass does not establish equivalent viewing service. A viewing-hour comparison requires compatible content quality, viewing counts, devices, distribution and end-of-life modules (shehabi-video-streaming-2014, Approach and DVD system assumptions).

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
mu_net_mass	Reference and intermediates	Mass	kg	Weigh bare recorded carriers. Exclude cases, inserts, wrap and shipping boxes from the denominator; retain their masses as inputs.
mu_count_mass	Count records	Mass	kg	Multiply accepted copy count by measured representative bare-carrier mass; retain sampling/calibration records. Count each carrier in a multi-disc set.
mu_electricity	Electricity	Net calorific value	MJ	Preserve the audited energy property; exact conversion is 1 kWh = 3.6 MJ. Record grid, voltage, losses and handover boundary; purchased electricity is distinct from primary energy.
mu_water	Make-up and discharge	Mass	kg	Convert volume only with a documented density and measurement conditions; never count circulating water repeatedly as external supply.
mu_formulations	Ink, adhesive and gas	Mass	kg	Separate purchased formulation from active or cured solids. Record chemistry and curing state. Gas-volume conversion requires density at recorded temperature and pressure.
mu_tools	Stamper and target service	Mass	kg	Reconcile weighed receipts, retirement and stock changes with service allocation. Raw metal alone does not represent a manufactured tool.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Existing authorized edited video master; purchased materials and finished stampers for replication, or complete purchased blank DVD-R for duplication
starting_condition_role	Foreground handover for physical-copy production; not proof of zero upstream burden
product_classification_scope	Recorded-video physical goods; a separate service identity does not exclude that service's manufacturing operations from producing the good
recursive_input_rule	Expand purchased inputs through matching upstream datasets. Do not recursively treat the finished edition as its own input. Link internal transfers once and cancel only on aggregation.
upstream_dataset_requirement	Link material, finished-stamper, blank-media, packaging, energy and offsite-treatment supply chains at their actual handover states; disclose time, geography, technology and completeness. Purchased blanks replace embedded carrier manufacturing, not recording.
disclosure	Distinguish foreground and upstream coverage. Film origination, casting, shooting, creative editing and rights acquisition are outside this physical-copy module; complete content-product claims require a separately justified contribution. Post-dispatch distribution, playback and postconsumer treatment require additional modules.

rule_id	applies_to	rule	source_ids
sb_identity	product_scope	Apply the goods boundary and exclusions in sections 1–2; originals with all rights and reproduction services have distinct category identities.	un-cpc-3-0-explanatory-notes-2025
sb_routes	disc_production	Include molding, metallization and bonding for replication. Complete blank DVD-R supply instead requires writing/finalization and upstream blank-media manufacture; do not duplicate its embedded resin, metal or adhesive as foreground inputs.	nist-sp-500-252-2003
sb_operations	site_operations	Include attributable edition preparation, test runs, rejects, rework, standby, line support and packing according to section 8 protocols.
sb_stamper	purchased_tools	Include the purchased finished stamper's upstream manufacture. Onsite mastering/electroforming instead requires a measured extension covering the actual glass-master, photoresist, plating, rinse and species-specific discharge exchanges, replacing the purchased-stamper operation.
sb_complete	route_instantiation	Confirm every inclusion_condition by recipe, meter or waste record. Add separate atomic exchanges for actual additional chemicals, fuels, refrigerant losses, transport and treatment; absence from this representative list never proves zero use.
sb_supply	upstream_links	Include inbound transport and offsite treatment through matched supplier/route datasets and check overlap. Onsite treatment needs its own measured inventory; a waste transfer is not an elementary emission.	us-epa-life-cycle-cd-dvd
sb_claims	downstream_use	Label results as physical-copy production data. Do not infer total video-service impacts, comparative streaming benefits or viewing lifetime without compatible additional modules.	shehabi-video-streaming-2014

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
edition_preparation	Edition preparation and file verification	required		foreground production	Work apportioned to 1 kg final accepted carrier
disc_production	Disc production and quality control	required	Lot route selects replication or DVD-R recording through individual exchange conditions	foreground production	Accepted unpackaged DVD mass transferred to packing
packing	Packing and dispatch release	required		conditioning	1 kg net saleable recorded DVD, packaging separately measured

Each card identifies one exchange. Its inclusion_condition must be evaluated for the declared lot. Document absence of conditional exchanges, reconcile internal DVD transfers by lot, and match supplier datasets to the stated physical product state. Internal transfers are bookkeeping links, not additional external outputs.

7. Allocation and Co-product Handling

These PCR bookkeeping rules use measured production records from section 8.

rule_id	applies_to	rule	source_ids
al_subdivide	shared_operations	Prefer separate lot meters. Allocate residual shared electricity by measured machine time multiplied by representative power and reconcile to the meter; sales revenue is not the default driver.
al_edition	edition_preparation	Spread physical-edition preparation over documented released copies in the actual campaign; reconcile repeat runs and revise the denominator. Do not assume unlimited future copies.
al_tools	stamper_service	Allocate finished-stamper manufacture and retirement by identified tool and actual service shots, including failed copies. Their burden remains with accepted output. Disclose provisional remaining service for tools still in use.
al_rework	internal_transfers	Keep rework energy and losses. Cancel internal DVD and clean-polycarbonate recirculation only in aggregate models, retaining reconciliation records. Only outgoing material is external waste.
al_scrap	recovered_material	Record actual waste transfers and treatment without automatic avoided-virgin-material credit. Any separate recycling-credit scenario requires explicit boundaries and no overlap with upstream credits.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_net_output	All rows	M = accepted released copy count × measured bare-carrier mass for one homogeneous edition; require M > 0.	cp_disc; cp_packing	Final net carrier mass M in kg
calc_normalize	External exchanges	q_i = attributable period quantity Q_i / M. Apply allocation before normalization. Reference product is exactly 1 kg by definition.	Relevant protocol; M	Exchange per 1 kg net carrier
calc_stocks	Material consumption	Q = opening stock + receipts - closing stock - unused supplier returns. Reconcile retained material, losses and waste; track internal recirculation separately.	cp_disc; cp_tools; cp_packing; cp_waste	Net input and material balance
calc_transfer	Internal DVD transfers	Transfer out = transfer in after documented inter-period inventory adjustment; count returned rework once.	cp_disc; cp_packing	Linked intermediate mass
calc_energy	Electricity	E_MJ = 3.6 × E_kWh; sum preparation, production and packing after checking meter-boundary overlap.	cp_edition; cp_utilities; cp_pack_energy	Purchased electricity MJ
calc_tool_share	Stamper	Lot tool share = tool burden × lot shots / documented total service shots. Disclose and update provisional remaining-service estimates.	cp_tools	Lot-attributable tool input/waste
calc_water_balance	Water and vapour	Make-up + opening stock = blowdown + evaporation + other measured departures + closing stock. Explain residuals with measurement uncertainty; do not assign them automatically to evaporation.	cp_utilities; cp_waste	Verified water balance and vapour
calc_argon_balance	Argon release	Purchased gas + opening stock - closing stock - unused returns = recovered gas + verified air release.	cp_utilities	Argon release by mass

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_scope	Dataset identity	Declare carrier, edition, route, handover states, period and original-content/downstream exclusions.	BOM; supplier boundaries; reference qualifiers
dq_measurement	All rows	Separate measured, allocated and calculated quantities with uncertainty, calibration and missing-data treatment.	Protocol-linked records and calculation workbook
dq_coverage	Reporting period	Cover the complete campaign or reporting period including startup and rejects; explain representativeness and extrapolation.	Campaign and meter coverage logs
dq_readability	Finished carriers	Retain content-integrity, readability, compatibility and defect acceptance evidence; handling guidance does not establish a guaranteed lifetime.	Site QA; nist-sp-500-252-2003 sections 4–5
dq_waste	Waste and emissions	Distinguish waste transfers from environmental releases; identify chemistry, receiver and compartment. Missing identity is not zero quantity.	Transfers; analyses; balances; release records
dq_other_media	Non-DVD routes	Provide a complete carrier-specific exchange list and quality basis before applying these rules to tape, Blu-ray or Video-CD.	Actual carrier bill, recording route and acceptance tests

9. Validation Rules

rule_id	applies_to	rule	source_ids
val_identity	reference_flow	Require all qualifiers, positive accepted net mass and a recorded-video good; blank and software media cannot be the final reference.	un-cpc-3-0-explanatory-notes-2025
val_route	inventory	Check one route per lot; replication materials and complete blank supply cannot both represent the same carrier manufacture.	nist-sp-500-252-2003
val_rows	flow_identity	Each row is one atomic exchange with correct type, physical state, property, unit and compartment. Keep blank UUIDs explicitly unresolved; no silent proxy substitution.
val_records	amounts	Require protocol-linked records, drivers, conversions and calculations. Reject unexplained negative quantities, missing conditional evidence and unsourced replacement defaults.
val_balances	balances	Reconcile copy counts, carrier and packaging mass, wastes, tool stocks, water/argon balances, transfers and meters against documented uncertainty; no universal percentage tolerance is prescribed.
val_quality	final_product	Require traceable content/readability tests and handling-damage records. Rejects and destroyed copies are excluded from saleable output.	nist-sp-500-252-2003
val_claims	dataset_use	Disclose upstream coverage and excluded creative-production, distribution, use and end-of-life stages; prohibit viewing-service comparisons without compatible added modules.	shehabi-video-streaming-2014
