1. A metadata display control method for a broadcast receiver, comprising:
- receiving a broadcast program and metadata of the broadcast program at a primary display terminal from a first broadcast channel;
transmitting the metadata to a secondary display terminal while displaying the broadcast program;
displaying a plurality of items constituting the metadata received from the primary display terminal at the secondary display terminal;
transmitting selection information encoded based on a first format to the primary display terminal via a radio link established between the primary display terminal and the secondary display terminal in response to selection of one of the plurality of items;
decoding and re-encoding the selection information based on a second format;
transmitting the re-encoded selection information from the primary display terminal to a broadcast station, the re-encoded selection information comprising an identification of the broadcast program, indexing information of the selected item, and request information for sub-metadata of the selected item;
receiving the sub-metadata from the broadcast station at the primary display terminal in response to transmitting the re-encoded selection information to the broadcast station;
transmitting the sub-metadata from the primary display terminal to the secondary display terminal; and
displaying the sub-metadata at the secondary display terminal,wherein the metadata comprises broadcast program-specific information and program guide information.

10. A metadata display control system for a broadcast receiver, comprising:
-
a primary display terminal comprising a first short range wireless communication module and a return channel to a broadcast station, the primary display terminal configured to receive, through another channel, a broadcast program and metadata of the broadcast program; and a secondary display terminal comprising a second short range wireless communication module, the secondary display terminal configured to receive the metadata through a radio link established between the first short range wireless communication module and the second short range wireless communication module and further configured to display a plurality of items constituting the metadata, wherein the secondary display terminal is further configured to transmit selection information of a selected item of the metadata to the primary display terminal through the radio link in response to selection of one of the plurality of items, the selection information being encoded according to a first format, wherein the primary display terminal is further configured to; decode and re-encode the selection information based on a second format; transmit the re-encoded selection information to the broadcast station through the return channel, the re-encoded selection information comprising an identification of the broadcast program, indexing information of the selected item, and request information for sub-metadata of the selected item; and transmit the sub-metadata corresponding to the re-encoded selection information to the secondary display terminal, and wherein the metadata comprises broadcast program-specific information and program guide information. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method, comprising:
-
receiving, via a first channel, broadcast programing and metadata associated with the broadcast programing, the metadata comprising broadcast program-specific information and program guide information; displaying the broadcast programming; transmitting the metadata to a secondary display device for display, the metadata corresponding to a plurality of selectable items; receiving selection information encoded according to a first format via a radio link with the secondary display device, the selection information being associated with selection of one of the selectable items; decoding and re-encoding the selection information according to a second format; transmitting, via a second channel, the re-encoded selection information to a broadcast station, the re-encoded selection information comprising an identification of the broadcast program, indexing information of the selected item, and request information for sub-metadata of the selected item; receiving, in response to transmitting the re-encoded selection information, the sub-metadata; and transmitting the sub-metadata to the secondary display device for display. - View Dependent Claims (17, 18)

19. A method, comprising:
-
receiving metadata from a primary display device, the metadata being associated with broadcast programming being displayed by the primary display device; displaying a plurality of selectable items constituting the metadata; receiving selection of one of the plurality of selectable items; generating selection information associated with the selection, the selection information comprising an indexing number associated with the one selectable item, an identifier associated with the broadcast programing, and request information associated with sub-metadata; transmitting, via a radio link, the selection information to the primary display device for transmission to a broadcaster of the broadcast programming; receiving the sub-metadata associated with the selection information from the primary display device; and displaying the sub-metadata, wherein an encoding of the selection information to the primary display device is different than an encoding of the selection information to the broadcaster. - View Dependent Claims (20)
