Cost-Optimized Energy Compliance Testing for Smart TV Streaming Devices: Achieving Milliwatt-Precision Power Measurement at Sub-One-Thousand-Dollar per Setup
Bibliographic record
Abstract
Industry-standard power measurement rigs used in consumer electronics energy compliance laboratories commonly cost between five thousand and eight thousand US dollars per setup. This creates a practical barrier when test organizations want to scale horizontally across many device benches, product lines, and lab locations. This paper describes a cost-optimized hardware configuration used in production to perform regulatory power measurements on shipping streaming stick devices. The configuration achieves zero point zero one watt, or ten milliwatt, measurement precision at approximately six hundred US dollars per setup, roughly an order of magnitude lower than the reference alternatives. The paper covers the regulatory background that drives instrument selection, including US Department of Energy and California Energy Commission requirements, the European Union Ecodesign framework for off mode, standby mode, and networked standby, and the corresponding standards in Canada, India, and Japan. It then covers the selection criteria for the power meter and supporting accessories, the calibration steps used to validate that lower-cost instrumentation is sufficient for the methodology the regulations require, and two production case studies. The first case study covers power validation for an energy efficiency feature deployed across three streaming device models. The second covers power profiling for an on-device dialogue enhancement feature that performs real-time audio neural network processing on streaming sticks. The paper concludes with a decision framework that test engineering organizations can use when sizing power test capacity against capital budget.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
