Abstract
A digital broadcast receiver is provided, including a receiver which receives a plurality of broadcast signals, a channel scanner which scans the plurality of broadcast signals and acquires service information (SI) related to the plurality of broadcast signals, and a controller which selects a broadcast signal having a preset type of SI from among the acquired SI, and updates channel information.
Claims19
A digital broadcast receiver comprising:
- a receiver configured to receive a plurality of broadcast signals corresponding to a plurality of broadcast channels;
- a channel scanner configured to acquire service information (SI) related to the plurality of broadcast channels;
- a controller configured to select a type of SI, from among program specific information (PSI)-type information and program service information protocol (PSIP)-type information, and to display channel information based on the selected type of SI;
- and
- a signal processor configured to receive and process only a broadcast signal of a channel of the selected type of SI and output a broadcast channel based on the processed broadcast signal,
- wherein, in response to the PSI-type information being the selected type of SI, the signal processor is configured to output only the broadcast channel having the PSI-type information and the controller is configured to display the channel information, including the broadcast channel having the PSI-type information and not including a broadcast channel having the PSIP-type information.
A method of updating channel information using a digital broadcast receiver, the method comprising:
- receiving a plurality of broadcast signals corresponding to a plurality of broadcast channels;
- acquiring service information (SI) related to the plurality of broadcast signals by scanning the plurality of broadcast channels;
- and
- selecting a type of SI, from among program specific information (PSI)-type information and program service information protocol (PSIP)-type information, and displaying channel information based on the selected type of SI;
- and
- processing only a broadcast signal of a channel of the selected type of SI and outputting a broadcast channel based on the processed broadcast signal,
- wherein, in response to the PSI-type information being the selected type of SI, the outputting comprises outputting only the broadcast channel having the PSI-type informaiton and the displaying the channel information comprising displaying the channel information, including a broadcast channel having the PSI-type information and not including a broadcast channel having the PSIP-type information.
A non-transitory computer readable storage medium configured to be implemented by a processor of a computer, causing the computer to perform a method of updating channel information using a digital broadcast receiver, the method comprising:
- receiving a plurality of broadcast signals corresponding to a plurality of broadcast channels;
- acquiring service information (SI) of the plurality of broadcast signals by scanning a plurality of broadcast channels in a predetermined cycle;
- and
- selecting a type of SI, from among program specific information (PSI)-type information and program service information protocol (PSIP)-type information, and displaying channel information based on the selected type of SI,
- processing only a broadcast signal of a channel of the selected type of SI and outputting a broadcast channel based on the processed broadcast signal,
- wherein in response to the PSI-type information being the selected type of SI, the outputting comprises outputting only the broadcast channel having the PSI-type information and the displaying the channel information comprising displaying the channel information, including a broadcast channel having the PSI-type information and not including a broadcast channel having the PSIP-type information.
