Abstract: Advertisements are shown to users when the queue underflows to avoid video stalls in players/plugins so users see minimum disruption in video quality. The advertisements are pre-fetched and cached at the mobile phone to schedule them during queue underflows. If there is no congestion in the network, the queue does no underflow and advertisements are shown only to meet ad contracts. During network congestion or disruption, the queue might underflow and specific advertisements are shown to equalize network unavailability until sufficient video data has been received.
Abstract translation: 当队列下溢时，向用户显示广告，以避免播放器/插件中的视频停滞，因此用户看到视频质量最小化。 在移动电话上预先抓取和缓存广告，以便在队列下溢期间进行安排。 如果网络中没有拥塞，则队列不会下溢，并且仅显示广告以满足广告合同。 在网络拥塞或中断期间，队列可能会下溢，并显示特定广告，以均衡网络不可用性，直到收到足够的视频数据。
