In a general aspect, a computer-readable storage medium can be configured to store instructions that when executed cause a processor of a host device to perform a process. The instructions can include instructions to determine that a first region of a current image is identical to a first region of a prior image, and instructions to determine that a second region of the current image is different from a second region of the prior image. The instructions can also include instructions to calculate, in response to the determination that the second region of the current image is different, a rate of change associated with the portion of the second region, and instructions to identify a portion of the second region of the current image for encoding based on the rate of change associated with the portion of the second region of the current image based on a threshold value.

Hybridized image encoding based on region volatility

In one general aspect, a method can include receiving at a host device via a remote desktop session a first carrier packet including a first set of event packets where each event packet from the first set of event packets includes an input value produced via an input device. The method can include receiving a second carrier packet including a second set of event packets duplicating at least a portion of the first set of event packets included in the first carrier packet, and identifying a portion of the second set of event packets as duplicates of the first set of event packets. The method can also include identifying an event packet excluded from the portion of the second set of event packets, and registering an input value included in the event packet in response to the identifying of the event packet.

Transmission of input values using an unreliable communication link

In one general aspect, a computer-readable storage medium can store instructions that when executed cause a client device to perform a process. The instructions comprising instructions to define a plurality of event packets where each event packet from the plurality of event packets includes an input value from a user interface device associated with the client device, and instructions to define, at a first time, a first carrier packet including the plurality of event packets. The instructions can also include instructions to define an additional event packet representing an additional input value from the user interface device associated with the client device, and define, at a second time, a second carrier packet including the additional event packet and at least a portion of the plurality of event packets.
