Maintenance methods of digital signage and troubleshooting and warning methods, digital signage playing systems and players thereof

A troubleshooting and warning method of digital signage, applied to a digital signage, comprising:

• performing a sampling operation on a screen image of the digital signage to obtain a plurality of sampled pixels according to a sampling rate;
• determining whether the sampled pixels are all black pixels;
• and
• in response to determining that all of the sampled pixels are black pixels, determining that the screen image is abnormal and automatically restarting playback software used for playing the screen image to replay the screen image.

A digital signage playback system, comprising:

• a digital signage, configured to play multimedia information;
• and
• a player electrically connected to the digital signage, configured to provide the multimedia information for playing on the digital signage;
• wherein the player is configured to detect processor usage statuses of one or more processes in a processing list corresponding to playback software, determine whether a predetermined condition is satisfied based on the processor usage statuses of the one or more processes, and in response to determining that the predetermined condition is satisfied, activate a screen analysis module to detect whether a screen image is abnormal and activate a troubleshooting module to automatically perform an automatic troubleshooting procedure in response to the screen detection module detecting that the screen image is abnormal.

A player, electrically connected to a digital signage, comprising:

• a storage device for storing multimedia information;
• and
• a processor coupled to the storage device, configured to provide the multimedia information to be played on the digital signage;
• wherein the processor is configured to activate a monitoring module for detecting processor usage statuses of one or more processes in a processing list corresponding to playback software, determine whether a predetermined condition is satisfied based on the processor usage statuses of the one or more processes, and in response to determining that the predetermined condition is satisfied, activate a screen analysis module to detect whether a screen image is abnormal and activate a troubleshooting module to automatically perform an automatic troubleshooting procedure in response to the screen detection module detecting that the screen image is abnormal.

A signal detection and troubleshooting and warning method of a digital signage, applied to a player of the digital signage, wherein the player comprises at least a monitoring module, a screen analysis module and a troubleshooting module, the method comprising:

• loading and detecting processor usage statuses of one or more processes in a processing list corresponding to playback software via the monitoring module;
• determining whether a predetermined condition is satisfied based on the processor usage statuses of the one or more processes;
• detecting whether a screen image is abnormal via the screen analysis module in response to determining that the predetermined condition is satisfied;
• and
• automatically performing an automatic troubleshooting procedure via the troubleshooting module in response to the screen detection module detecting that the screen image is abnormal.
