该对象表示最通用的展示类型。虽然 “banner” 一词在其他语境中可能有非常特定的含义，但在这里它可以是多种形态：简单的静态图片、可展开的广告单元，甚至 banner 内嵌视频（更通用、功能更全的视频广告单元参见第 3.2.7 节的 Video 对象）。Banner 对象数组也可出现于 Video 内部，描述 VAST 规范定义的可选伴生广告（companion ads）。Banner 作为 Imp 的子对象出现，即表示该展示以 banner 类型提供；经发布方许可，同一展示还可通过在 Imp 下并列包含 video、audio 和/或 native 类型对象的方式同时以这些类型提供，但针对该展示的任一具体出价，只能符合所供类型中的一种。译稿校对中ENThis object represents the most general type of impression. Although the term “banner” may have very specific meaning in other contexts, here it can be many things including a simple static image, an expandable ad unit, or even in-banner video (refer to the Video object in Section 3.2.7 for the more generalized and full featured video ad units). An array of Banner objects can also appear within the Video to describe optional companion ads defined in the VAST specification. The presence of a Banner as a subordinate of the Imp object indicates that this impression is offered as a banner type impression. At the publisher’s discretion, that same impression may also be offered as video, audio, and/or native by also including as Imp subordinates objects of those types. However, any given bid for the impression must conform to one of the offered types.

译注
译者注Banner 在 2.6 中的定位：仍是最通用的展示类型对象，但 2.6 已移除 2.5 中弃用的 wmax/hmax/wmin/hmin 字段，尺寸表达统一收敛到 format 数组与 w/h 精确值；接入 2.6 的存量系统应在序列化层清理这些旧字段。译稿校对中
btype 的取值含义：直接内联枚举了四种被拦截的加载方式（XHTML 文本/横幅、JavaScript、iframe）；实践中主要拦截 JavaScript 与 iframe 类型以控制安全与性能风险，出价前应核对创意交付形态。译稿校对中
id / vcm 的伴生广告配套：伴生广告场景下，id 用于关联 VAST 中的伴生创意，vcm 声明渲染模式（伴随/尾帧）；未传 id 会导致播放器无法将伴生 banner 与 VAST 标记对应。译稿校对中
topframe 与可见性：顶层框架内的创意能力与可见性测量均优于 iframe；买方在可见性导向的采买中应关注该标志，并在定价模型中区分。译稿校对中
