Abstract
A broadcast signal includes an information table (EIT) or an application information table (AIT) which includes a descriptor. The descriptor includes image data representative of a thumbnail image to be displayed within an electronic program guide (EPG). A decoder decodes the EIT or AIT from a broadcast signal, and an application manager displays the thumbnail image within an EPG to indicate that a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
Claims33
A broadcast signal for use in a digital television (DTV) receiver, the broadcast signal comprising an information table, the information table comprising a descriptor which includes image data representative of a thumbnail image to be displayed within an electronic program guide (EPG) for indicating whether a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
A broadcast signal for use in a digital television (DTV) receiver, the broadcast signal comprising an event information table (EIT), the EIT comprising a descriptor which includes image data representative of a thumbnail image to be displayed within an electronic program guide (EPG) for indicating whether a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
A broadcast signal for use in a digital television (DTV) receiver, the broadcast signal comprising an application information table (AIT), the AIT comprising a descriptor which includes image data representative of a thumbnail image to be displayed within an electronic program guide (EPG) for indicating whether a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
An apparatus of decoding a broadcast signal, the apparatus comprising:
- a decoder for decoding an information table from a broadcast signal, the decoded information table comprising a descriptor which contains image data representative of a thumbnail image;
- and
- an application manager for displaying an electronic program guide (EPG) and for displaying the thumbnail image within the EPG in order to indicate that a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
An apparatus of decoding a broadcast signal, the apparatus comprising:
- a decoder for decoding an event information table (EIT) from a broadcast signal, the decoded EIT comprising a descriptor which includes image data representative of a thumbnail image;
- and
- an application manager for displaying an electronic program guide (EPG) and for displaying the thumbnail image within the EPG in order to indicate that a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
An apparatus of decoding a broadcast signal, the apparatus comprising:
- a decoder for decoding an application information table (AIT) from a broadcast signal, the decoded AIT comprising a descriptor which includes image data representative of a thumbnail image;
- and
- an application manager for displaying an electronic program guide (EPG) and for displaying the thumbnail image within the EPG in order to indicate that a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
A method of decoding a broadcast signal, the method comprising:
- decoding an information table from a broadcast signal, the information table comprising a descriptor which contains image data representative of an thumbnail image;
- displaying an electronic program guide (EPG) on a screen;
- and
- displaying the thumbnail image within the EPG in order to indicate that a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
A method of decoding a broadcast signal, the method comprising:
- decoding an event information table (EIT) from a broadcast signal, the decoded EIT comprising a descriptor which includes image data representative of a thumbnail image;
- displaying an electronic program guide (EPG) on a screen;
- and
- displaying the thumbnail image within the EPG in order to indicate that a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
A method of decoding a broadcast signal, the method comprising:
- decoding an application information table (AIT) from a broadcast signal, the decoded AIT comprising a descriptor which includes image data representative of a thumbnail image;
- displaying an electronic program guide (EPG) on a screen;
- and
- displaying the thumbnail image within the EPG in order to indicate that a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
A broadcast signal for use in a digital television (DTV) receiver, the broadcast signal comprising an information table, the information table comprising a descriptor which includes image data representative of a thumbnail image to be displayed on a screen to indicate a summary of broadcast data carried on a channel.
An apparatus of decoding a broadcast signal, the apparatus comprising:
- a decoder for decoding an information table from a broadcast signal, the decoded information table comprising a descriptor which contains image data representative of a thumbnail image;
- and
- an application manager for displaying a data broadcasting guide and for displaying the thumbnail image within the data broadcasting guide in order to indicate a summary of broadcast data carried on a channel.
A method of decoding a broadcast signal, the method comprising:
- decoding an information table from a broadcast signal, the information table comprising a descriptor which contains image data representative of an thumbnail image;
- displaying a data broadcasting guide on a screen;
- and
- displaying the thumbnail image within the data broadcasting guide to indicate a summary of broadcast data carried on a channel.
