The embodiment of the present disclosure discloses the framework managing method and framework managing device of the interactive function card of the smart television. The framework managing method comprises the following steps of: receiving the card update instruction; downloading the new on-line card from the server according to the downloading instruction when the card update instruction is served as the downloading instruction; receiving the card list startup instruction, starting the card list, wherein the card list includes the plurality of cards, and each card has the corresponding interactive function; receiving the user selection instruction, and operating the corresponding card contained in the card list through the host program.

An apparatus and method for providing an interactive service to devices using different digital broadcast middleware standards are provided. The apparatus includes an execution information providing module which provides execution information regarding an application that has been executed in a first device using a first middleware standard so that the application can be executed in a second device using a second middleware standard; and a request execution module which receives a request issued by the second device during the execution of the application in the second device, and performs an operation corresponding to the received request.

The invention provides a Common Interface, CI, host (10) comprising a Universal Serial Bus, USB, controller (30) for connecting to a USB device (31) of a Common Interface Conditional Access Module, CICAM, (20) the USB controller being configured to usea first logical pipe (33) for transferring control information between the CICAM and the CI host; anda second logical pipe (35) for transmitting to the CICAM a first CA encrypted signal.a third logical pipe (37) for receiving a first CA decrypted signal, corresponding to the first CA encrypted signal, from the CICAM, wherein USB isochronous pipes are used as the second logical pipe (35) and the third logical pipe (37) when the first CA encrypted signal originates from a DVB broadcast and USB bulk pipes are used as the second logical pipe (35) and the third logical pipe (37) when the first CA encrypted signal originates from an Internet source.
