Method of processing a broadcast signal and a receiver for implementing the same

A device for receiving broadcast signal, comprising:

• a first tuner and a second tuner configured to independently synchronize a first transmit stream and a second transmit stream, respectively;
• a transmit stream processor configured to convert each of the first and second transmit streams into a plurality of audible audio signals, a plurality of displayable video signals, and a plurality of displayable data signals;
• a controller configured to provide switching control signal and display control signal based on channel selected by a user;
• a switching unit configured to output a data broadcast associated with a first broadcast channel selected from the plurality of displayable data signals and the video and the audio associated with a second broadcast channel selected from the plurality of displayable video signals and audible audio signals, respectively;
• a display module configured to display the data broadcast associated with the first broadcast channel in a first display area and the video associated with the second broadcast channel in a second display area;
• and
• a first speaker and a second speaker for outputting audible audio of the first broadcast channel and the second broadcast channel, respectively.

A method of displaying independently displaying at least one video and at least one data broadcast by a receiver, the method comprising:

• synchronizing at least two transmit streams independently;
• converting the at least one transmit stream into a plurality of audible audio signals, a plurality of displayable video signals, and a plurality of displayable data signals;
• providing switching control signal and display control signal based on channel selected by a user;
• outputting a data broadcast associated with a first broadcast channel and the video and the audio associated with a second broadcast channel;
• displaying a video of the first broadcast channel in a first display area and a data of the second broadcast channel in a second display area;
• and
• outputting audible audio of at least two different broadcast channels.
