a middleware component;

a plurality of management components arranged and configured to emulate the capabilities of a physical set-top box, wherein the plurality of management components comprising a presentation manager, a codec manager and a conditional access manager, wherein the IPTV content is video content, and wherein the management components are configured to perform video processing of the video content, user interface (UI) layout generation, and remote-control key handling, and wherein the video processing comprises decoding the IPTV content, video scaling of the IPTV content, video positioning of the IPTV content, chroma keying of the IPTV content, and alpha blending of the IPTV content; and

a plurality of interfaces to enable communication between said plurality of management components and said middleware, wherein the plurality of interfaces comprises a graphics interface, a MUX interface, a Conditional Access interface, a Media interface, and Events Interface, a System Settings interface and/or a Persistent Storage interface.

2. The set-top box emulation system of claim 1, wherein at least one of the pluralities of interfaces connects to at least one interface provided by the middleware component.

3. The set-top box emulation system of claim 1, wherein the plurality of management components also includes a browser, said browser being configured for integration with said middleware component.

4. The set-top box emulation system of claim 3, wherein said middleware component is inserted into the document object model (DOM) of said browser.

5. The set-top box emulation system of claim 4, wherein said middleware component integrates with said browser via a second plurality of interfaces.

6. The set-top box emulation system of claim 1, wherein a user interface is managed by said middleware component.

7. The set-top box emulation system of claim 1, wherein the plurality of management components also includes a dynamic video source selection (DVSS) component, said DVSS component comprising further subcomponents and being configured to integrate with said plurality of management components, said subcomponents comprising at least one of a PVR controller, an IGMP client, a RTSP client and a DVB-T client.

8. A method of emulating functions of a set-top box so as to present IPTV content to a viewer on an electronic device, the method comprising:

receiving IPTV content by said electronic device from a network;

using a plurality of set-top box emulation components to create an emulated set-top box environment within said electronic device, wherein the IPTV content is video content, and wherein the emulation components perform video processing of the video content, user interface (UI) layout generation, and remote-control key handling, and wherein the video processing comprises decoding the IPTV content, video scaling of the IPTV content, video positioning of the IPTV content, chroma keying of the IPTV content, and alpha blending of the IPTV content; and

executing a middleware component within said emulated environment, said middleware component communicating with said emulated environment via a plurality of interfaces.

9. The method of claim 8, wherein the plurality of set-top box emulation components comprises one or more of a presentation manager, a codec manager and/or a conditional access manager.

10. The method of claim 9, wherein the plurality of interfaces comprises at least one of a graphics interface, a MUX interface, a Conditional Access interface, a Media interface, and Events Interface, a System Settings interface and/or a Persistent Storage interface.

11. A computer-implemented method of emulating a physical set-top box (STB), comprising:

receiving Internet Protocol Television (IPTV) content over a connection of an electronic device from an Internet Protocol (IP) closed network;

executing by the electronic device a middleware component, designed originally for use with the physical STB, including emulating hardware capabilities of the physical STB to process the IPTV content; and

presenting the IPTV content on a display of the electronic device, wherein the IPTV content is video content, and wherein the emulated hardware capabilities includes video processing of the video content, user interface (UI) layout generation, and remote-control key handling, and wherein the video processing comprises decoding the IPTV content, video scaling of the IPTV content, video positioning of the IPTV content, chroma keying of the IPTV content, and alpha blending of the IPTV content.

12. The method of claim 11, wherein said executing comprises:

providing a plurality of STB emulation components to create an emulated STB environment within said electronic device; and

executing the middleware component within the emulated STB environment via a plurality of interfaces of the emulated STB environment that enables communication between the plurality of STB emulation components and the middleware component.

13. The method of claim 12, wherein the plurality of interfaces and the middleware component are embedded within a Document Object Model (DOM) of a browser operating on the electronic device, and wherein said executing further comprises:

receiving DOM requests at the browser; and

translating the DOM requests into application programming interface (API) requests for interaction with the middleware component.

14. The method of claim 12, wherein said receiving comprises receiving the IPTV content from a head-end of an IPTV system over the IP closed network, and wherein said executing comprises:

managing access by the electronic device to the IPTV content using a conditional access (CA) manager and a CA interface between the middleware component and the CA manager;

managing presentation of the IPTV content on the display using a presentation manager and a graphics interface, wherein the graphics interface enables the middleware component with mechanism to inform the underlying graphical subsystem to refresh the display; and

managing presentation of a user interface layout on the display using the presentation manager and a multiplexing (MUX) interface, wherein the MUX interface enables the middleware component to control user interface (UI) and video mixing of the IPTV content for said presenting.

15. The method of claim 14, wherein the IPTV content is encoded by the head-end of the IPTV system, and wherein said executing further comprises:

managing requesting and decoding of the IPTV content by the electronic device using a codec manager, a media interface, and a network interface, wherein the media interface and network interface enable the middleware component to control requesting, decoding, and displaying of the IPTV content;

receiving one or more events over an event interface, wherein the event interface enables the middleware component to receive inputs or actions from an operating system (OS) based interface driver for one or more user input devices;

managing one or more settings of the emulated STB environment using a system setting interface, wherein the system interface enables an operator to configure the emulated STB environment without having to make changes to the plurality of STB emulation components themselves; and
