Abstract: In general, this disclosure describes media stream transmission techniques for a computing device. The computing device captures a first media item and identifies a primary portion of the first media item and a secondary portion of the first media item different than the primary portion. The computing device applies a first compression algorithm to the primary portion of the first media item to generate a compressed primary portion. The computing device applies a second compression algorithm to the secondary portion of the first media item to generate a compressed secondary portion, where a data compression ratio of the second compression algorithm is greater than a data compression ratio of the first compression algorithm. The computing device transmits, to a central computing device, the compressed primary portion of the first media item and the compressed secondary portion of the first media item.

Abstract: In general, this disclosure describes media stream transmission techniques for a computing device. The computing device may capture an image of a local background environment. The computing device may record a first media stream that includes at least a portion of the image of the background environment and at least one movement of at least one object through the background environment. The computing device may remove the image of the background environment from the first media stream to create a second media stream that includes the movement of the object without the image of the background environment. The computing device may determine a bandwidth of a network over which the second media stream will be transmitted and perform further alterations to the second media stream if the current bandwidth is less than a bandwidth threshold level in order to reduce the bandwidth needed to transmit the second media stream.
