在数字户外（DOOH）与 CTV 中，一次程序化展示机会常被称为一个“时段（spot）”，而一次展示是观看它的受众中的一个独立个体。因此，需要在竞价请求中传递乘数的标准方式，以表示展示总量。本对象包含展示乘数，并描述乘数取值的来源。译稿校对中ENA programmatic impression is often referred to as a ‘spot’ in digital out-of-home and CTV, with an impression being a unique member of the audience viewing it. Therefore, a standard means of passing a multiplier in the bid request, representing the total quantity of impressions, is required. This object includes the impression multiplier, and describes the source of the multiplier value.

译注
译者注Qty 的计价含义：DOOH/CTV 中一次展示机会可触达多位受众，multiplier 将单次机会折算为展示量；计费口径（按机会还是按乘数后展示）应在交易前与交易平台明确，避免结算争议。译稿校对中
sourcetype / vendor 的可信度：乘数来源（发布方自报或第三方测量）直接影响可信度；第三方测量（如受众测量商）通常更受买方采信，采购时应核对 vendor 资质。译稿校对中
