A multi-display system includes a host system that supports both graphics and video based frames for multiple remote displays, multiple users or a combination of the two. For each display and for each frame, a multi-display processor responsively manages each necessary aspect of the remote display frame. The necessary portions of the remote display frame are further processed, encoded and where necessary, transmitted over a network to the remote display for each user. In some embodiments, the host system manages a remote desktop protocol and can still transmit encoded video or encoded frame information where the encoded video may be generated within the host system or provided from an external program source. Embodiments integrate the multi-display processor with either the video decoder unit, graphics processing unit, network controller, main memory controller, or any combination thereof The encoding process is optimized for network traffic and attention is paid to assure that all users have low latency interactive capabilities.

A method for single sign-on in a client-server system including a server and a client and a remote presentation protocol based on ITU T.120, communicates between the client node and the server. The client obtains a ticket for a user operating the client. The ticket identifies the security context of the user on the client. Upon connecting the client to the server, the ticket is transferred from the client to the server. The server authenticates the ticket with a security authority and when authenticated the server receives from the security authority a security context for the ticket. When the client so requests, applications are launched using that security context. Preferably, the server is a Microsoft Terminal Server and the remote presentation protocol is Microsoft Remote Desktop Protocol (RDP). The ticket transfer preferably uses a channel within the remote presentation protocol, such as an RDP virtual channel.

The present invention is directed towards systems and methods for providing Quality of Service (QoS) via a flow controlled tunnel. Traffic from a plurality of applications may be directed into a single connection or flow-controlled tunnel and QoS policies may be applied across the plurality of applications without configuration of individual link speeds, enabling QoS scheduling to dynamically adjust traffic transmission and reception rates to ensure priority management of applications regardless of a final endpoint of the application communications. Accordingly, traffic of different types, including VPN, HTTP, Voice-over-IP (VoIP), remote desktop protocol traffic, or other traffic may be easily balanced and prioritized. In many embodiments, the tunnel may be transparent to applications, such that without any application configuration, application traffic may still be prioritized by QoS requirements.

Quasi peer-to-peer communication between random clients in the system is made possible by means of routing on the server.

Embodiments of the present invention are directed to a remote desktop communication protocol that includes spatial and temporal compression techniques. Multimedia presentation data is generated at a server from a source. A compression facility modifies the presentation data by both spatially and temporally compressing the presentation data to transmittable data. In some embodiments, a check is performed to ensure that the least amount of data is selected prior to sending the transmittable data to a remote client. The remote client receives the transmittable data and re-constructs the original multimedia presentation data. In some embodiments that use lossy compression, the reconstruction may not exactly re-construct the original multimedia presentation data. Once re-created, the remote client presents the presentation data at the remote client. The presentation data could be audio, video, or other data or a combination of them.

A method for controlling the different power states of a ClientBlade™ from a remote desktop environment is described. The remote user's (device) connects his computer device (laptop or desktop) to the ClientBlade™ (at the Blade Center) via a Remote Desktop Protocol (RDP), which performs minimal video compression and provides an Ethernet connection back to the Blade Center. The user inputs a pre-defined key sequence, which initiates a power state interface (or input screen). The power state interface allows the user to select one of several power states. Once the power state is selected, a TCP / IP packet is generated and transmitted from the computer device to the ClientBlade™. The packet invokes the selected power state at the ClientBlade™. Once the power state is activated, a completion message verifying the power state change is sent back to the end user's computer device.

Systems, methods and computer readable media are disclosed for improving compression efficiency and quality in a remote session via tile image classification and variable encoding. A server determines a set of codecs that are shared by both the server and a corresponding client. Then, when it receives an image, it determines whether classification of the image is required.

Where classification of the image is required, the server classifies the image (e.g. the image comprises either text or photograph), and based on that classification determines a codec with which to encode the image, and a fidelity to use on the encoding. The server performs that encoding with the codec and the fidelity, and then sends this encoded image to the client.
