Videophone input apparatus

TECHNICAL FIELD

The present application generally relates to a method, a system and an apparatus for providing a videophone service.

BRIEF DESCRIPTION OF RELATED DEVELOPMENTS

Due to recent advances of mobile telecommunications, popularity of mobile phones has been greatly increased. At the same time, the usage of fixed landline phone connections at home has been reduced. Video calls are widely used as a communication method providing people not only speech but streaming video of the other party as well. High-speed telecommunication networks enable video call activation between computers and cellular phones.

However, using computers or cellular phones for video calls has certain drawbacks. First, such devices are typically personal in a sense that they are carried with the person owning the device. Thus, receiving or making a video call to/from home always requires that there is someone at home with a capable video call device. Second, current videophones utilized by cellular phones have a limited input/output means, such as a camera and display. For example, if several persons would like get involved to the video call, arranging the persons around the cellular phone is difficult and uncomfortable. Third, current videophones utilized by computers require large devices, such as a personal computer and a monitor placed to a room of an apartment, in which the video call is to be established. Such arrangement is not acceptable in most living rooms. Furthermore, a complex registrations and device configurations may be needed until the video call is available. Even furthermore, users need to be aware of available services that they may even registrate for.

Thus, a solution is needed that is easy-to-use, low-cost and highly-functional as a shared object. Furthermore, such a videophone apparatus is needed that would provide a relatively large display for the video call without disturbing the interior decoration of the home apartment or the office.

FIG. 7 shows a schematic picture of a stack relating to a videophone input apparatus 120 according to an example embodiment.

Hardware 710 comprises all hardware components of the videophone input apparatus 120, such as processor, memory, camera and RF, for example. Next level 720 of the stack comprises operating system, drivers and kernel. With the aid of the firmware and device drivers, the kernel provides the most basic level of control over all of the hardware of the apparatus. The kernel may manage memory access for programs in the RAM, determine which programs get access to which hardware resources, set up or reset the CPU's operating states for optimal operation at all times, and organize the data for long-term non-volatile storage with file systems on such media as disks, tapes, flash memory, etc.

The operating system provides an interface between an application program 750 and the hardware 710, so that the application program 750 can interact with the hardware 710 only by obeying rules and procedures programmed into the operating system 720. The operating system is also a set of services which simplify development and execution of application programs. Executing an application program involves the creation of a process by the operating system kernel which assigns memory space and other resources, establishes a priority for the process in multi-tasking systems, loads program binary code into memory, and initiates execution of the application program which then interacts with the user and with hardware devices.

An audio/video (A/V) level 740 of the stack provides communication functionalities for the audio and video data between the videophone input apparatus 120 and the A/V output apparatus 110, such as a television, for example.

A communication level 730 of the stack provides communication functionalities for the wireless communications between the videophone input apparatus 120 and the server apparatus 130, for example.

A main application level 750 comprises the main application layer of the apparatus 120. On top of the application layer 750, plurality of clients may exist. A call client 770 may comprise a videophone call client, for example, such as a Skype client.

Any IP-based audio/visual content may be delivered by the videophone input apparatus 120. On top of the stack, a user interface level 780 is provided. The user interface level 780 is configured to provide the format, content and outlook of the information to a user of the apparatus 120.

FIG. 8 shows a schematic picture of a stack relating to a server apparatus 130 according to an example embodiment.

Hardware 810 comprises all hardware components of the server apparatus 130, such as processor and memory, for example.

Next level 820 of the stack comprises operating system, implemented by Linux, for example. The operating system 820 provides an interface between an application server 820, a main application 870 and the hardware 810, configuring interaction with the hardware 810 only by obeying rules and procedures programmed into the operating system 820. The operating system 820 is also a set of services which simplify development and execution of application programs. Executing an application program involves the creation of a process by the operating system which assigns memory space and other resources, establishes a priority for the process in multi-tasking systems, loads program binary code into memory, and initiates execution of the application program which then interacts with the main application, users and hardware devices 810.

An application server 830 provides runtime environment for server-side components (such as Java servlets and Java server pages). The application server 830 may contain the further architectural components, such as web container, name server and security server, for example. The web container runs within the application server 830 and handles requests for servlets, Java server page files, and the web applications that contain them. The security server may provide security infrastructure and mechanisms to protect sensitive application resources and administrative resources and to address enterprise end-to-end security requirements on authentication, on resource access control, on data integrity, confidentiality, and privacy, and on secure interoperability.

A transmission control protocol (TCP) layer 840 of the server stack enables that the server apparatus 130 may serve several clients 120, 160 concurrently, by creating a child process for each client and establishing a TCP connection between the child process and the client. Unique TCP sockets are created for each connection 860. The connections 860 are in established state, when a socket-to-socket virtual connection (TCP session), is established with the remote socket, providing a duplex byte stream. The server apparatus 130 may create several concurrently established TCP sockets with the same local port number and local internet protocol (IP) address, each mapped to its own server-child process, serving its own client process. They are treated as different sockets by the operating system 820, since the remote socket address (the client IP address and/or port number) are different.

A structured query language (SQL) database level 850 of the stack provides communication functionalities for the server apparatus 130 between the server apparatus 130 and the database 131, 460, 470, for example.

A main application level 870 comprises the main application layer of the server apparatus 130. The server main application 870 may be correspond to the client side main application 750 described in FIG. 7. On top of the application layer 870, plurality of user interface layers may exist. The client user interface level 890 is configured to provide the format, content and outlook of the information to a user of the apparatus 120. The administrator user interface level 880 is configured to provide the format, content and outlook of the information to the administrator of the server 130 and the system 100.
