Multimedia system applying time of flight ranging and operating method thereof

A multimedia system applying time of flight ranging and comprising:

• a plurality of electronic devices, each comprising:
• a processing module;
• a time of flight module coupled to the processing module and configured to perform a time of flight ranging operation;
• and
• a communication module coupled to the processing module and configured to perform wireless communication,
• wherein the electronic devices communicate via the respective communication modules to formulate an operation protocol and respective unique identifiers and to perform a time slot synchronization between different electronic devices, and the electronic devices perform the time of flight ranging operation sequentially via the respective time of flight modules according to the operation protocol and the respective unique identifiers.
