The disclosure relates more specifically to application discovery techniques useful in coordi- nating first-screen audiovisual devices and second-screen computing devices. BACKGROUND 10 [0002] The approaches described in this section are approaches that could be pursued, but not necessarily approaches that have been previously conceived or pursued. Therefore, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section. [0003] Video-based entertainment systems in homes and commercial environments may include a variety of primary 15 viewing systems such as televisions, digital video recorders, disc players, and set-top boxes that are compatible with cable or satellite television signaling systems. Such primary viewing systems often include complete special-purpose computers that are capable of hosting application programs relating to entertainment or other functions, and are usually capable of driving or displaying a program on a large-screen display or display unit. In the same environments, the use of other special-purpose computing devices and general purpose computing devices such as smartphones, tablet com- 20 puters, laptop computers, netbook computers, and other computers and workstations is commonplace. However, while certain protocols are available for discovering devices on a local network, such as SSDP and Bonjour/mDNS, in current technology it has been difficult for applications hosted on the computing devices to identify, obtain data from, and coordinate operations with applications that may run on the primary viewing systems. As another example, a laptop computer on a local network may have no way to identify and then cause launching, on the primary viewing system, a 25 particular entertainment-oriented computer program application that is hosted on the primary viewing system. Conse- quently, in the past users typically have had to interact directly with the primary viewing system to identify, launch, use, and shut down the applications that are hosted on the primary viewing system. [0004] US 2006/258289 A1 (DUA ROBIN [US]) 16 November 2006 (2006-11-16) discloses a wireless media player that employs the use of integrated Radio Frequency Identification (RFID) technology to exchange communication settings, 30 media capability, and other parameters with an external device that also has integrated RFID technology. The automatic exchange of settings and other information via a proximity-based RFID data exchange allows a media player to quickly establish a secure communication link with another device via a commonly supported wireless protocol such as Ultra Wideband (UWB) or Bluetooth. [0005] US 2009/111453 A1 (HSU TONY S T [TW] ET AL) 30 April 2009 (2009-04-30) discloses a technique for auto- 35 deploying an application from a mobile communication device to a host in a pervasive computing environment. The technique can detect and can select an available host around the mobile communication device. In response to the issued auto-deploying request, the selected application can be auto-deployed into the available host for execution.

One goal of the disclosure is to enable consumer electronics device owners to enjoy seamless integration of smartphone and tablet computer applications 15 as part of an audiovisual-oriented entertainment experience. 1.1 Terminology [0010] In this disclosure, the following terms may have the following meanings: 20 [0011] First screen: a television, disc player, set-top box, game console, digital video recorder, or similar device primarily capable of playing or generating a visual display of an audiovisual program. A first screen device is often a primary viewing system in the user environment. [0012] Second screen: a smartphone, tablet computer, laptop computer, netbook computer, or other personal com- puting device. A second screen device is often a secondary viewing system but often has more powerful or generalized 25 computing and input capabilities than the first screen device. [0013] Discovery server: a computing device that hosts, executes or implements the server side of the protocols described herein. In one embodiment, the discovery server is a first screen device. [0014] Discovery client: a computing device that can discover and request to launch computer program applications that are located or hosted on a discovery server.

Espoo 20.5.2015 Thesis supervisor: Prof. Raimo A. Kantola Thesis advisor: PhD Mikko Välimäki aalto university abstract of the school of electrical engineering master’s thesis Author: Peng Liu Title: Developing a Solution for Multimedia Home Networking Date: 20.5.2015 Language: English Number of pages: 9+66 Department of Communications and Networking Professorship: Networking Technology Code: S-38 Supervisor: Prof. Raimo A. Kantola Advisor: PhD Mikko Välimäki In recent years, the rapid development of electronics and computer science has enabled home networking devices to become more affordable and more powerful. Several widely used multimedia-streaming solutions have become available in the market. However, as a result of their different technical designs, these standards naturally experience serious compatibility issues. Thus, end users can have several multimedia devices, with each one using a distinctive, unique protocol, making it challenging or even impossible sometimes to share media between those devices. These compatibility issues have motivated the need to determine the technological features common to the existing multimedia-streaming standards and to develop a more easy-to-use multimedia home networking solution. This thesis compares the modern solutions for multimedia home networking (MHN), including AirPlay, Miracast, Chromecast, and especially the Digital Liv- ing Network Alliance (DLNA) standard due to its wide adoption. By conducting research on the features and capabilities of these existing solutions, a suitable mo- bile solution for MHN, which takes advantage of AirPlay, Discovery and Launch (DIAL), and DLNA, is proposed for the Android platform.

Buzzwords such as "TV Everywhere" is something that both hard- ware manufacturers, content providers and television networks are pursuing to great lengths. At the core of such marketing schemes is the availability of platform-independent content consumption. In a Utopian setting, the end-user should never have to worry if he or she is currently using a smart TV, tablet, phone or computer to view a video or photos, play music or play games. Taking the concept even further, the devices should also be able to connect and communicate with each other seamlessly. Having for example a television set (first screen) controlled by a mobile phone (second screen) is commonly referred to as companion device interaction and is what this thesis has investigated. More specifically, a way of discovering and launch- ing a first screen application from a second screen application using the zero configuration discovery protocol named DIAL has been implemented into a cross-platform messaging solution.

Although the technology behind such experiences has existed for a couple of years, end users are now truly starting to grasp the concept and benefits of multi- screen. The company, at which the thesis was performed at, provides a cloud-based messaging solution for Internet connected devices, which en- ables multi-screen use cases. To increase the amount of supported platforms in the solution, new technologies frequently needs to be integrated. In this thesis I have performed an exploratory research & development project with the aim to integrate the Google Cast technology in this multi-screen solu- tion. The fundamental difference in how the two ecosystems were designed resulted in a companion device framework that acted as a wrapper over the technologies. The framework was implemented on the Android platform to- gether with a set of demo applications. The proposed solution should be seen as a starting point for integrating different multi-screen technologies within a single companion device framework.
