A virtual desktop can be remoted to a client device by transmitting a video stream using a video coding format, such as H.264, where higher resolution video can be streamed than natively supported by the encoder or decoder. The encoder framebuffer is divided into a plurality of equal size child buffers, each child buffer is assigned an identifier for identifying the child buffer. Padding pixels can be added to the child buffers to make the child buffer size acceptable for the video coding format. The child buffers are encoded using the video coding format and the encoded frames are transmitted to a client. On the decoder side, the encoded child frames are decoded, padding pixels are removed, and the data is used to update corresponding child buffers in a framebuffer on the client display system.

Split framebuffer encoding

Image cache collaboration is described to enable multiple clients to share image data in a remote desktop environment. A centralized cache manager maintains information about all image caches on all client devices which have established connections to the server. When an update to a portion of the GUI of a virtual desktop for a first client device is detected, the central cache manager can determine whether any other client devices contain the requested image data in their respective image caches. If such a device is identified, the server transmits a message to the first client device, identifying the second client device that contains the requested image data in its respective image cache. The first client device may then request and receive the image data from the second client device over the LAN on which both devices reside, thereby obtaining the data with less latency.

Image cache collaboration between clients in remote desktop environments

In a computer-implemented method for copying/pasting items in a virtual desktop infrastructure (VDI) environment a request is received to copy an item from a first virtual machine and paste the item to a second virtual machine. A unique identifier of the item is generated. An indication is received at the second virtual machine, from a communication broker, that the item is at the first virtual machine. The item is received at the second virtual machine directly from the first virtual machine.
