Abstract
Disclosed are a display device and a method for operating the same. According to an embodiment of the present disclosure, a display device includes a display, a tuner including a first demodulator and a plurality of RF ICs which receive a signal through a tuned channel, and a processor including a second demodulator and configured to lock a channel through each demodulator according to a tuning request, process a signal demodulated through a demodulator selected based on a threshold sensitivity value for signal detection individually set in the each demodulator, and control a video to be output through the display.
Claims13
A display device comprising:
- a display;
- a tuner including a first demodulator and a plurality of radio frequency (RF) Integrated Chips (ICs) which receive a signal through a tuned channel;
- and
- a processor including a second demodulator and configured to lock a channel through each of the demodulators according to a tuning request, process a signal demodulated through a demodulator selected based on a threshold sensitivity value for signal detection individually set in each of the demodulators, and control a video to be output through the display,
- wherein the processor is configured to receive a channel change signal, and store log data related to cracking of an output video of a changed channel and channel skipping according to the received channel change signal, and
- wherein the processor is configured to analyze the log data, and determine or change a threshold sensitivity value for each of the demodulators based on the analyzed log data, and
- wherein the demodulator is selected based on log data information indicating comparison results for demodulator performance in locking more channels.
A method for operating a display device, comprising:
- receiving a signal through a tuned channel;
- locking, by each of a plurality of demodulators, a channel;
- processing a signal demodulated through a demodulator selected based on a threshold sensitivity value for signal detection individually set in each of the demodulators;
- and
- performing control such that a video is output through a display,
- wherein the method further comprises:
- receiving a channel change signal,
- storing log data related to cracking of an output video of a changed channel and channel skipping according to the received channel change signal,
- analyzing the log data, and
- determining or changing a threshold sensitivity value for each of the demodulators based on the analyzed log data, and
- wherein the demodulator is selected based on log data information indicating comparison results for demodulator performance in locking more channels.
