    Abstract: The disclosure generally relates to detecting playback buffer underrun at a sink device to improve streaming media quality. More particularly, according to various embodiments, a media source device may establish a connection with the sink device according to a short-range wireless communication protocol (e.g., Bluetooth) and stream multimedia data to the sink device over the established connection. The sink device may then store the streamed multimedia data in a playback buffer, render the streamed multimedia data from the playback buffer, and send a signal to the source device to indicate a status associated with the playback buffer. Accordingly, the source device may increase local resources allocated to streaming the multimedia data to the sink device in response to the status signal indicating an underrun condition in the playback buffer at the sink device (e.g., where the buffered multimedia data stored therein has fallen below a threshold).

    Abstract translation: 本公开一般涉及在宿设备处检测重放缓冲器欠载以改善流媒体质量。 更具体地，根据各种实施例，媒体源设备可以根据短距离无线通信协议（例如，蓝牙）建立与宿设备的连接，并通过建立的连接将多媒体数据流传输到宿设备。 接收器装置然后可以将流式多媒体数据存储在重放缓冲器中，从再现缓冲器中渲染流式多媒体数据，并向源装置发送信号以指示与重放缓冲器相关联的状态。 因此，源设备可以响应于指示在宿设备处的重放缓冲器中的欠载条件的状态信号（例如，其中存储在其中的缓冲多媒体数据已经下降到其中的地方）来增加分配给多媒体数据流的多媒体数据的本地资源 一个门槛）。

    Abstract: Methods, devices, and systems for controlling imaging operations in electronic image capture devices are disclosed. In some aspects, a device includes processor coupled to a camera module, a user input surface, and a memory. The processor can be configured to receive, from the user input surface, a continuous user input. The continuous user input can include, at least, a first portion and a second portion. The processor can be further configured to control a first imaging operation based on a first input type received during the first portion and control a second imaging operation based on a second input type received during the second portion. The first input type can include movement of an input element relative to the user input surface, for example, and the second imaging operation can be different than the first imaging operation.
