This application claims priority from and the benefit of Korean Patent Application No. 10-2017-0069545, filed on Jun. 5, 2017, which is hereby incorporated by reference for all purposes as if fully set forth herein.
Exemplary embodiments/implementations of the invention relate generally to a technique for connecting a digital device to a remote personal computer (PC) and using a PC function in the digital device.
In general, a television (TV) has a function of receiving a broadcasting image and displaying the received image. Since the device specification of a conventional TV is low, a general function of the conventional TV relates to outputting, that is, displaying an image. A PC service may be available through connection to a separate external device to use a PC function on such the conventional TV.
With a high-end chipset being installed on a TV, smart TVs that support various services are provided, as disclosed in Korean Patent Application Publication No. 10-2012-0047487. A smart TV may provide various functions, such as web surfing, video-on-demand (VOD) watching, a social network service, and a game, by installing various applications (apps) through combination of an Internet access function with the TV. Here, the PC service may be used by downloading and installing a PC service application through a store provided from the smart TV to use the PC function on the smart TV. However, since a platform of a smart TV is different for each manufacturer, an application installable in each supported smart TV may be limited. Although the application is provided through the store, there may be some constraints in installing the application based on an environment of a device.
Accordingly, there is a need for a technology that enables a PC function to be available even on a generic TV, which is not a smart TV, without a separate physical device to provide a PC function.

Since an OS environment is supported in the set-top box, a PC resource provided from the remote PC 110 may be available at any time. Accordingly, a network cost may decrease gradually. Accordingly, in terms of cost, it may be further effective to use the remote PC service from the remote PC 110 through the digital device 100 rather than replacing hardware of the digital device 100.
Also, the digital device 100 may redirect an I/O device connected to the digital device 100 to the remote PC 110. The digital device 100 may perform a management, such as share, allocate, and control the I/O device for the remote PC 110. For example, the digital device 100 may redirect, to the remote PC 110, a control signal of the I/O device connected to the digital device 100, and, in response to the control, the remote PC 110 may provide the remote PC service including a function of the I/O device to the digital device 100. Also, the digital device 100 may manage resources associated with a resource pool of the remote PC 110.
According to a conventional DaaS service, a separate device for using a remote service of a desktop or a separate application executed on a general desktop, for example, WINDOWS and MAC is necessary. According to exemplary embodiments, the OS may be constructed on the digital device, and the digital device with a low processing power may utilize a high performance remote PC service. Also, issue of incompatibility between applications provided by various digital device manufacturers may be overcome.
The systems or apparatuses described herein may be implemented using hardware components, software components, and/or a combination thereof. For example, the apparatuses and the components described herein may be implemented using one or more general-purpose or special purpose computers, such as, for example, a processor, a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a programmable logic unit (PLU), a microprocessor, or any other device capable of responding to and executing instructions in a defined manner. The processing device may run an operating system (OS) and one or more software applications that run on the OS. The processing device also may access, store, manipulate, process, and create data in response to execution of the software. For purpose of simplicity, the description of a processing device is used as singular; however, one skilled in the art will be appreciated that a processing device may include multiple processing elements and/or multiple types of processing elements. For example, a processing device may include multiple processors or a processor and a controller. In addition, different processing configurations are possible, such as parallel processors.
The software may include a computer program, a piece of code, an instruction, or some combination thereof, for independently or collectively instructing or configuring the processing device to operate as desired. Software and data may be embodied permanently or temporarily in any type of machine, component, physical or virtual equipment, computer storage medium or device, or in a propagated signal wave capable of providing instructions or data to or being interpreted by the processing device. The software also may be distributed over network coupled computer systems so that the software is stored and executed in a distributed fashion. In particular, the software and data may be stored by one or more computer readable storage mediums.
