Desktop virtualization may be used by enterprises that have sensitive data and applications and cannot afford (e.g. security reasons) for the sensitive data or applications to reside on a client side machine. Consequently, with desktop virtualization, a thin client my run on the client side machine with the sensitive data and applications running on a server controlled by the enterprise. In this situation, the application is actually running on the server and all the user sees is just a user interface (UI) on the client side machine. Accordingly, a system administrator with the enterprise may update the server side image. Then, when a user logs into the server, the user gets the latest software that the system administrator wants to push.
FIG. 1 is a block diagram of a virtualized environment 100. As illustrated in FIG. 1, with desktop virtualization, the actual processing may be done on a server 105 instead of a client-side machine 110. Such applications (i.e., applications running in virtualized environment 100) may be referred to as “virtualized applications.” For example, a first application 115 and a second application 120 may actually be running on server 105. Client-side machine 110 may render and display a first user interface 125 and a second user interface 130 respectively corresponding to first application 115 and a second application 120. Virtualized applications may be acceptable for non-real-time applications (e.g. word processing, spreadsheets, etc.) in which raw data (e.g. key inputs, etc.) may be sent from the client-side machine to the server where the virtualized application running on the server gets the user input and process the data.
Real-time audio/video conferencing applications may run as virtualized applications in the aforementioned virtualized environment. Real-time audio/video conferencing applications may take raw audio/video data captured from the client-side machine, encode the data, and transmit the encoded data over a wire for example. In addition real-time audio/video conferencing applications may receive an encoded data stream from a network, decode the encoded data stream, and render the decoded data stream on the client-side machine. However, with virtualized real-time audio/video conferencing applications, there are additional hops (e.g. through the server) that the “virtualized” real time application needs to traverse compared to “non-virtualized” real time application running locally on the client-side machine.
When sending and receiving real-time audio/video in a non-virtualized real time application, all the processing is done on client-side machines and not on a server. For example, the client-side application catches audio/video from the devices, encodes, and sends it over a wire from the client-side machine. In contrast to non-virtualized, with the virtualized real-time application, the captured raw audio/video data may be sent to the server, for example, by remoting the capturing device or by sending a raw data stream coming from capturing devices over a remote desktop channel to the server. Moreover, the server in the virtualized environment sends out an encoded stream. Consequently, in the virtualized environment, there are additional hops (e.g. from the client-side machines to the server) in the path of audio/video. These additional hops may increase delay/latency in the real-time audio/video data flow.
FIG. 2 shows a real-time media system 200 consistent with embodiments of the inventions. Real-time media system 200 may comprise a first client-side machine 205 (e.g. a local computing device), a second client-side machine 210 (e.g. a remote computing device), a server 215, and a network 220. Consistent with embodiments of the invention, non-virtualized, real-time audio/video conferencing may be performed between first client-side machine 205 and second client-side machine 210 over network 220.
If embodiments of the invention used a server path (i.e. a first hop 225 and a second hop 230), there would be additional hops (e.g. from first client-side machine 205 to server 215 and from server 215 to second client-side machine 210) in the path of the audio/video data between first client-side machine 205 and second client-side machine 210. These additional hops may increase, for example, delay/latency in the real-time audio/video data flow between first client-side machine 205 and second client-side machine 210.
Consistent with embodiments of the invention, the aforementioned delay/latency in the real-time audio/video data flow between first client-side machine 205 and second client-side machine 210 may be avoided by not involving server 215 in the real-time audio/video data flow. For example the audio/video data may be transmitted between first client-side machine 205 and second client-side machine 210 over a media path 235 that does no involve server 215. However, if media path 235 is not established or if it fails after it is established, the audio/video data may be transmitted between first client-side machine 205 and second client-side machine 210 over the server path.
Any one of first client-side machine 205, second client-side machine 210, and server 215 may comprise, but is not limited to, a desktop computer, a notebook computer, a mobile device, a smart telephone, or a personal digital assistant, for example. Network 220 may comprise the internet or any type network over which first client-side machine 205, second client-side machine 210, and server 215 may communicate. Any one of first client-side machine 205, second client-side machine 210, and server 215 may be implemented using, for example, a computing device 500 as described in greater detail below with respect to FIG. 5.
FIG. 3 is a flow chart setting forth the general stages involved in a method 300 consistent with an embodiment of the invention for providing real-time media optimization. Method 300 may be implemented using real-time media system 200 as described above. Ways to implement the stages of method 300 will be described in greater detail below.
Method 300 may begin at starting block 305 and proceed to stage 310 where first client-side machine 205 may establish a remote session with a remote computing device (e.g. second client-side machine 210.) For example, as shown in FIG. 4, an application 405 may be running on sever 215. Application 405 may comprise a videoconferencing application. Consistent with the remote session, a thin client running on first client-side machine 205 may render and display a user interface 415 corresponding to application 405 running on sever 215. Application 405 may complete a remote session between first client-side machine 205 and second client-side machine 210.
From stage 310, where first client-side machine 205 establishes the remote session, method 300 may advance to stage 320 where first client-side machine 205 may exchange, during the remote session, non-real-time media data with the remote computing device (e.g. second client-side machine 210) over the server path. For example, the exchanged non-real-time media data may comprise, for example, any non-audio or non-video data corresponding to a videoconferencing session between first client-side machine 205 and second client-side machine 210. For example, the non-real-time media data may comprise data corresponding to a location of first client-side machine 205 used, for example, for emergency 911 calls. The non-real-time media data may comprise, but is not limited to, client and server capabilities. These capabilities may be used to influence the direct communication between two clients.
Once first client-side machine 205 exchanges the non-real-time media data in stage 320, method 300 may continue to stage 330 where first client-side machine 205 may exchange, during the remote session, real-time media data with the remote computing device over media path 235. The real-time media data may comprise audio or video data. If embodiments of the invention used the server path (i.e. first hop 225 and second hop 230) for the real-time media data, there would be additional hops (e.g. from first client-side machine 205 to server 215 and from server 215 to second client-side machine 210) in the path of the audio/video data between first client-side machine 205 and second client-side machine 210. These additional hops may increase, for example, delay/latency in the real-time audio/video data flow between first client-side machine 205 and second client-side machine 210.
Embodiments of the invention may avoid the aforementioned delay/latency by having a remote media manager (RMM) (e.g. a remote media manager application 410) on first client-side machine 205 that may capture, encode, and transmit the real-time media data (e.g. audio/video and other modalities can be added) directly from first client-side machine 205 to second client-side machine 210, without involving server 215 in media path 235. Moreover, RMM may receive encoded real-time media data from network 220 (e.g. sent directly from second client-side machine 210 over media path 235), decode the received encoded real-time media data, and render directly into user interface 415 the decoded real-time media data it received from second client-side machine 210. RMM may work in conjunction with application 405 on server 215. For example, application 405 may send and receive data using input devices (e.g. a camera 420 and a microphone 425) and output devices (e.g. a speaker 430) connected to first client-side machine 205. RMM may also utilize the same input and output devices. Consequently, RMM may work in conjunction with application 405 on server 215 in order to share input and output devices. In other words, the input and output devices may be shared between data sent/received over media path 235 and data sent/received over the server path.
Another instance where RMM may work in conjunction with application 405 on server 215 is where data from media path 235 and data from the server path is synchronized. On example may comprise geometry tracking. Geometry tracking may allow for (when video data is coming straight to first client-side machine 205 sent directly from second client-side machine 210 over media path 235 and bypassing the server path) placing, on display 415, the video where it should be shown. For example, application 405 may send the position and shape of the video region to first client-side machine 205 on the server path. First client-side machine 205 may then render the video (coming on media path 235) on a “proxy” window that tracks information (e.g. position and shape) sent by application 405. Application 405 may continuously monitor any changes that may happen to the video location and shape and may keep updating first client-side machine 205 with this information. First client-side machine 205 in-turn may keep updating the “proxy” window with application 405's info. In this way, the video display on first client-side machine 205 may be synchronized.
Furthermore, first client-side machine 205 exchanging, during the remote session, real-time media data with the remote computing device over media path 235 may comprise performing network address translation (NAT) from first client-side machine 205 to the remote computing device. In computer networking, network address translation (NAT) may comprise the process of modifying network address information in datagram (IP) packet headers while in transit across a traffic routing device for the purpose of remapping one IP address space into another. After first client-side machine 205 exchanges the real-time media data in stage 330, method 300 may then end at stage 350.
An embodiment consistent with the invention may comprise a system for providing real-time media optimization. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to establish a remote session with a remote computing device. Moreover, the processing unit may be operative to exchange, during the remote session, non-real-time media data with the remote computing device over a server path and exchange, during the remote session, real-time media data with the remote computing device over a media path.
Another embodiment consistent with the invention may comprise a system for providing real-time media optimization. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to establish a remote session between a local computing device and a remote computing device. In addition, the processing unit may be operative to exchange, during the remote session, non-real-time media data between the local computing device and the remote computing device over a server path including a server. Furthermore, the processing unit may be operative to exchange, during the remote session, real-time media data comprising audio and video data between the local computing device and the remote computing device over a media path. The server is not in the media path.
Yet another embodiment consistent with the invention may comprise a system for providing real-time media optimization. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to establish a remote session with a remote computing device. The processing unit being operative to establish the remote session may comprise the processing unit being operative to establish a server path wherein a server is involved in the server path, and to establish a media path wherein the server is not involved in the server path and the media path is established directly with the remote computing device. Moreover, the processing unit may be operative to exchange, during the remote session, non-real-time media data with the remote computing device over the server path and to exchange, during the remote session, real-time media data with the remote computing device over the media path.
