The Evolution of Video Applications. When the previous Cisco Enterprise Qo. S Design Guide was published in 2. Interactive videoGenerally describes H. Streaming videoGenerally describes streaming or video on demand Vo. D applications video flows were unidirectional either unicast or multicast and were not time sensitive due to significant application buffering. However, at the time of writing this document 2. Figure 1 1. Figure 1 1Video Application Evolution. Consider first the streaming video branchthe earliest sets of video applications were Vo. D streams to the desktop. Vo. D streams can include pre recorded content such as employee communications, training, e learning, and social interaction content. Today, due to the ease of content creation, on demand content may either be professionally produced top down or self produced bottom up. It is important to also note that not all Vo. Call Recording Software For Panasonic Pbx System. D content is necessarily business related, as non business, entertainment oriented content is often widely available for on demand video viewing. Vo. D applications soon expanded to include the development and support of live or broadcast video streams to the desktop. Broadcast streams may include company meetings, special events, internal corporate announcements or similar content. As such, broadcast streaming video content is typically professionally produced, top down content. Thereafter, with the proliferation of flat screen digital displays, it became increasingly apparent that the desktop is not the only display option for streaming video. Thus, digital signage began to emerge as another streaming video application for both on demand and broadcast video streams. Digital signage refers to centrally managed publishing solutions for delivering digital media to networked displays. For example, Cisco offers a Digital Media Player and an enterprise TV solution that works in conjunction with its Digital Media System to support a comprehensive digital signage solution. Digital signage can be used to broadcast internal information, such as sharing up to date schedules and news where people need it most or providing realtime location and directional guidance. Additionally, digital signage is an effective tool for marketing, helping companies to promote products and services directly to customers. Around the same time that digital signage was being developed, the advantages that IP brought to video were being gradually being applied to the video surveillance market. These advantages include the ability to forward live video streams to local or remote control centers for observation and efficient processing. Cisco offers comprehensive IP surveillance IPVS solutions, including IP cameras, hybrid analog to digital video gateways to facilitate transitioning from closed circuit TV surveillance solutions to IPVS, and IPVS management applications. Interestingly, video surveillance has a unique degree of interactivity not found in any other streaming video application, namely, that of having an observer interact with the video stream by sending control information to the transmitting video camera, for instance, to track an event in progress. On the interactive video side of the video application hemisphere, there has also been considerable application evolution. Basic video conferencing applications, which were initially dedicated room based units, evolved into software based PC applications. The factors behind this shift from room based hardware to PC based software were two fold The convenience of immediate desktop collaboration rather than having to book or hunt for an available video conferencing enabled room. The availability of inexpensive Webcams. Desktop video conferencing may be utilized on a one to one basis or may support a few participants simultaneously. Once video conferencing moved to software, a whole new range of communication possibilities opened up, which morphed desktop video conferencing applications into multimedia collaboration applications. Multimedia collaboration applications, including Cisco Unified Personal Communicator CUPC and Cisco Web. Ex, share not only voice and video, but also data applications, such as instant messaging, document and presentation sharing, application sharing, and other integrated multimedia features. However, not all interactive video migrated to the desktop. Room based video conferencing solutions continued to evolve and leveraged advances in high definition video and audio, leading to solutions like Cisco Tele. Presence. Additionally, application sharing capabilitiesborrowed from multimedia conferencing applicationswere added to these high definition room based video conferencing solutions. And video application evolution doesnt end here, but will continue to expand and morph over time as new demands and technologies emerge. The Transition to High Definition Media. One of the reasons traditional room to room video conferencing and desktop Webcam style video conferencing are sometimes questioned as less than effective communications systems is the reliance on low definition audio and video formats. On the other hand, high definition interactive media applications, like Cisco Tele. Presence, demonstrate how high definition audio and video can create an more effective remote collaboration experience, where meeting participants actually feel like they are in the same meeting room. Additionally, IP video surveillance cameras are migrating to high definition video in order to have the digital resolutions needed for new functions, such as pattern recognition and intelligent event triggering based on motion and visual characteristics. Cisco fully expects other media applications to migrate to high definition in the near future, as people become accustomed to the format in their lives as consumers, as well as the experiences starting to appear in the corporate environment.
