Abstract: Techniques for adaptive content transmission are described herein. During transmission of a content item, a network connection may be monitored to collect data corresponding to one or more network conditions associated with the transmission of the content item. Such network conditions may include, for example, network throughput, available network bandwidth, network latency and others. The collected data may be used to dynamically adjust one or more transmission attributes in connection with the transmitted content item. The one or more transmission attributes may be determined for adjustment at any desired transmission interval.

Abstract: Techniques for streaming content, such as a video game or whiteboard application, to multiple different clients are described herein. In some cases, differences may exist between characteristics of the different clients such as screen size, resolution, operating system, processors and memories and others. The different clients may be positioned in close proximity to one another or at remote locations with respect to one another. In some cases, different network conditions, such as available bandwidth, loss rates, latency, throughput and others, may exist for transmitting content to the different clients.

Abstract: Techniques for efficient bandwidth estimation are described herein. In some cases, the bandwidth estimation techniques disclosed herein may, for example, calculate bandwidth based on multiple packet groups transmitted at different times. Additionally, in some cases, the bandwidth estimation techniques disclosed herein may, for example, capture cross traffic and its effects on bandwidth. Furthermore, in some cases, the bandwidth estimation techniques disclosed herein may, for example, employ dynamic self-correcting techniques for more reliable estimates.

Abstract: Content may have associated interest information that indicates various areas of interest within images displayed during presentation of the content. An area of interest is an area for which a different encoding bitrate may be desired relative to another area. When an image is encoded for transmission, instructions may be provided to an encoding component for encoding of the image based on the associated interest information. The encoding component may then determine appropriate bitrates for different portions of the image based on the interest information while also satisfying overall bitrate constraints for the image as a whole.
