Abstract

A metadata display control method and system for a digital broadcast receiver for displaying metadata associated with a broadcast program on a secondary display terminal while displaying the broadcast program on a primary display terminal is provided. The metadata display control method includes 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, and displaying the metadata received from the primary display terminal at the secondary display terminal.

Claims

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; and

displaying the metadata received from the primary display terminal at the secondary display terminal.

2. The metadata display control method of claim 1, further comprising:

transmitting selection information to the primary display terminal via a radio link established between the primary display terminal and the secondary display terminal when one of items constituting the metadata is selected;

transmitting selection information of the selected item from the primary display terminal to a broadcast program provider;

receiving a sub-metadata from the broadcast program provider at the primary display terminal in response to the selection information;

transmitting the sub-metadata from the primary display terminal to the secondary display terminal; and

displaying the sub-metadata at the secondary display terminal.

3. The metadata display control method of claim 2, further comprising:

transmitting a channel switching request from the secondary display terminal to the primary display terminal, the channel switching request being a request to switch to a second broadcast channel; and

displaying a broadcast program received on the second broadcast channel at the primary display terminal.

4. The metadata display control method of claim 3, further comprising:

transmitting a metadata of the broadcast program of the second broadcast channel from the primary display terminal to the secondary display terminal in response to a request of the secondary display terminal; and

displaying the metadata of the broadcast program of the second broadcast channel at the secondary display terminal.

5. The metadata display control method of claim 4, wherein the metadata comprises detailed information of the broadcast program, supplementary service information, and program guide information of the broadcast channels.

6. The metadata display control method of claim 5, wherein the radio link between the primary display terminal and the secondary display terminal is established using one of Bluetooth®

, ZigBee®

, Ultra Wideband (UWB), RuBee®

s, and Infrared Data Association (IrDA).

7. The metadata display control method of claim 1, wherein the metadata comprises broadcast program-specific information and supplementary service information.

8. The metadata display control method of claim 2, wherein the primary display terminal transmits the selection information to the broadcast program provider through a return channel.

9. The metadata display control method of claim 1, further comprising receiving a command at the secondary terminal before receiving a broadcast program, the command determining whether to receive the metadata of the broadcast program.

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 program provider, the primary display terminal to receive 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 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 to display the metadata.

11. The metadata display control system of claim 10, wherein the secondary display terminal transmits selection information of a selected item to the primary display terminal through the radio link when one of items constituting the metadata is selected.

12. The metadata display control system of claim 11, wherein the primary display terminal transmits the selection information to the broadcast program provider through the return channel and transmits sub-metadata corresponding to the selection information to the secondary display terminal.

13. The metadata display control system of claim 12, wherein the secondary display terminal transmits a power control signal and a channel switching signal to the primary display terminal through the radio link.

14. The metadata display control system of claim 13, wherein the primary display terminal switches to a second broadcast channel when a channel switching signal is received, displays a broadcast program on the second broadcast channel, and transmits metadata of the broadcast program of the second broadcast channel to the secondary display terminal.

15. The metadata display control system of claim 14, wherein the secondary display terminal determines whether to display the metadata of the first broadcast channel or the metadata of the second broadcast channel.

16. The metadata display control system of claim 15, wherein the first short range wireless communication module and the second short range wireless communication module are each one of a Bluetooth®

module, a ZigBee®

module, an Ultra Wideband (UWB) module, a RuBee®

module, and an Infrared Data Association (IrDA) module.
