Abstract: A virtual channel table for broadcasting protocol and a method for broadcasting by using the virtual channel table includes identification information identifying and permitting discrimination of active and inactive channels contained in the virtual channel table. At a receiver, the virtual channel table transmitted from the transmitting side is parsed, thereby determining whether the current received channel is an active or inactive channel.

Abstract: In a cable network providing, among others, interactive video services, data cells carrying real-time data concerning, e.g., trick mode commands (pause, rewind and fast-forward) initiated by a user are instantly transmitted to a headend facility for immediate processing. The invention is premised upon a recognition that such real-time data typically does not fully utilize the transport capacity of the data cells. In accordance with the invention, non-real-time (NRT) data to be transmitted to the headend facility, although accorded a lower priority than the real-time data, is inserted into those underutilized data cells before their transmission, thereby fully exploiting the transport capacity of the data cells.

Abstract: A set-top box, which allows a user to input a key command in real time while displaying an animation sequence on an on-screen display (OSD) screen, and a method of outputting the OSD data of the set-top box is provided. The set-top box includes OSD control module that divides OSD animation data into a plurality of subsets, loads each of the subsets in every operating cycle, determines whether a user has input a key command in every operating cycle, and selectively provides the loaded subsets based on the determination result in every operating cycle, wherein the OSD animation data realizes an animation sequence when displayed. The set-top box further includes a combination control module that receives the loaded subsets of the OSD animation data from the OSD control module and overlays the data onto the decoded broadcast signal and provides the overlaid result to a display device.

Abstract: A MHP terminal device is provided with a network functionality. In addition to a broadcast interface for receiving a broadcast transport stream, the MHP terminal device comprises a local network interface. Via said interface, the MHP terminal device is connected to a local network, to which other network devices are connected as well. MHP applications can be inserted into local network transport streams transmitted from said network devices to said MHP terminal device. By means of these MHP applications, the network devices can be remotely controlled from the MHP terminal device, whereby commands and messages are exchanged via the local network.

Abstract: In order to switch the transmission medium between the Internet and broadcast waves, reception/playback of communication data received via first media, such as via the Internet from an external device, and broadcast data received via second media, such as via a broadcast network from a broadcast station, is switched.
