Abstract
In a broadcast receiving system for receiving the digital broadcast, when the selection of “channel selection menu” is inputted by the user, the channel information stored in a memory is read to decide whether the configuration of a sub-channel is identified during the current operation, and a descriptor “x” is assigned to the sub-channel not identified to be made displayed in the channel information list on “channel selection display,” thereby distinguishing it from other channels. This allows the channel whose sub-channel cannot be identified to be OSD displayed distinguishing it from other channels such as for analog broadcast and the like.
Claims6
A broadcast receiving system with a function of on-screen displaying channel information on a display device comprising:
- an input device for inputting an operation instruction to the system, a receiver for receiving coded digital/analog broadcasting signals originated from a broadcasting station,
- a digital/analog decoder for decoding the digital/analog broadcasting signals received by the receiver and outputting them to an image-displaying display device connected to the system,
- a memory for storing the channel information included in the broadcasting signals decoded by the digital decoder,
- an on-screen display (OSD) output circuit for making the display device to display a predetermined OSD, and
- a control unit for controlling the system, wherein the device receives digital broadcasting signals including one or a plurality of sub-channels for transmitting contents for one channel;
- wherein the control unit controls the system such that
- the receiver receives the broadcasting signals of a specified channel when the power switch of the system is closed, or in response to a channel change instruction inputted by the input device,
- the digital decoder decodes these broadcasting signals for analyzing the channel information from the decoded signals and for obtaining the channel information,
- the memory stores the information as storage data,
- the display device displays a channel selection display comprising a list of the channel information including at least the channel specified by the user, digital/analog identification, and broadcasting contents in response to an instruction for displaying the channel selection display by the user,
- wherein the channel information includes a predetermined descriptor in place of a sub-channel number when the channel information has not been analyzed and obtained in the current operation, and thus the sub-channel number cannot be designated based on the storage data stored in the memory.

A method for displaying channel information on a display device, the method comprising the acts of:
- receiving broadcast signals of a specified channel when a power switch is closed or in response to a channel change instruction;
- analyzing channel information of the specified channel;
- storing the channel information;
- and
- displaying a channel selection display comprising the channel information for the specified channel,
- wherein when channel information has not been analyzed for a particular channel, channel information for the particular channel is displayed with a sub-channel number with a predetermined descriptor, and wherein the sub-channel descriptor is displayed in place of a sub-channel number.
