# Televisions Key Product Criteria

**Effective Date: October 20, 2022**

## On Mode Requirements:

The following On Mode requirements are based on measurements taken per the ANSI/CTA-2037-C: Determination of Television Set Power Consumption.

For all TV/HTDs, On Mode Power (P_{OA}) metrics shall be determined through the following process:

**For PPSs tested without ABC enabled**: The metrics gathered while testing with ABC disabled shall represent P_{OA}and the DL for the PPS.**For PPSs tested with ABC enabled**: Measurements at different illuminance conditions are thus taken (at 4, 17, 50, and 140 lux) per the*ANSI/CTA-2037-C: Determination of Television Set Power Consumption*:*To calculate DL for the PPS*: The value of DL used to represent the PPS for the purpose of calculating_{POA_Average_Limit}per Equation 5 shall be the calculated average of the DL measurements taken at each illuminance condition, as outlined by Equation 1.*To calculate P*: The value of POA that represents the PPS for the purpose of calculating P_{OA}for the PPS_{OA_Average }per Equation 4 shall be the calculated average of the P_{OA}measurements for the PPS taken at each illuminance condition, as outlined by Equation 2.- Should the Brightest SDR PPS as determined through
*ANSI/CTA-2037-C*have ABC enabled by default, the default ABC-disabled metrics gathered while testing the PPS shall represent P_{OA}and the DL for the PPS. Performing calculations per Equations 1 and 2 will thus not be necessary for the PPS.

- If the value for the DL used to represent an SDR PPS is measured or calculated to be less than 20 cd/m
^{2}, then 20 cd/m^{2}shall be the DL value used to represent the PPS for the purpose of determining certification, and the value of P_{OA}used to represent the PPS shall be the interpolated P_{OA}value of the PPS when the TV/HTD is set to a DL of 20 cd/m^{2}. Likewise, if the value of the DL for an HDR10 PPS is less than 10 cd/m^{2}, then 10 cd/m^{2}shall be used as the DL representing the PPS for the purpose of determining certification, and the value of P_{OA}used to represent the PPS shall be the interpolated P_{OA}value of the PPS when the TV/HTD is set to a DL of 10 cd/m^{2}.- The P
_{OA}values of a PPS correlating to a projected DL of 20 cd/m^{2}or 10 cd/m^{2}shall be calculated through interpolation of the 2nd order polynomial trendline created by plotting all the PPS’s measured P_{OA}value datapoints against the measured DL values at the same points.- If the P
_{OA}value for the Brightest SDR PPS needs to be interpolated and the PPS has ABC enabled by default, include the ABC-enabled datapoints as measured per ANSI/CTA-2037-C when creating the 2nd order polynomial.

Products shall meet the On Mode Power Requirement as outlined by Equation 3:

- Should a TV not be capable of reading an HDR10 signal (e.g., the TV displays an error or blank screen when fed an HDR10 signal), P
_{OA}metrics associated with the HDR10 picture setting shall be omitted from calculations as presented by Equations 4 and 5.

## Standby Mode Requirements:

The following Standby Mode Requirements are based on measurements from the *Federal Test Procedure Standby-Passive Mode Test* as well as the series of additional Standby-Active Mode tests outlined in *ANSI/CTA-2037-C: Determination of Television Set Power Consumption*, that are designed to measure standby power in a more typical network environment (e.g., multicast traffic on the network).

- Standby-Passive Mode Power (P
_{STANDBY-PASSIVE}), as measured per Section 7.3.2*Standby-Passive Mode*of the Federal Test Procedure, shall be less than or equal to 0.5 W. - For TVs capable of network connectivity, Standby-Active Mode Power (P
_{STANDBY-ACTIVE}), as measured per*ANSI/CTA-2037-C*, shall be less than or equal to 1.0 W.
