Problems solved by technology
[0007] The purpose of the present invention is to solve the above technical problems and provide a method for synchronizing multimedia terminals to solve the problem of out-of-sync playback content caused by hardware differences and system random events running on the hardware. The present invention does not rely on Based on a separate synchronization signal generating device and related software and hardware, it effectively overcomes the problems of high dependence on auxiliary equipment such as clock source generation equipment, non-adaptiveness, high cost and maintenance costs when multimedia terminals are synchronized under existing technical conditions

Embodiment Construction
[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0035] In many multimedia playback applications, multiple multimedia terminals are required to synchronize the playback progress, but in fact, due to factors such as device differences between multimedia terminals and software running on hardware platforms affected by random events, the It is impossible to achieve synchronization on the playback content, so some technical innovations are needed to solve this problem. According to the multimedia synchronization method of the present invention, it does not depend on a separate synchronization signal generating device and related software and hardware, and effectively overcomes the high dependence on auxiliary equipment such as clock source generation equipment when multimedia termina...

The invention relates to the field of multimedia, in particular to a multimedia terminal synchronization technique, and provides a method for realizing synchronization of multimedia terminals. The method comprises the following steps: (1) a multimedia terminal receives synchronizing information in a local area network when entering the local area network; (2) if receiving the synchronizing information within the synchronous host machine setting time, the multimedia terminal serves as a synchronous slave machine and adjusts the play progress and contents of the synchronizing information; if not receiving the synchronizing information within the synchronous host machine setting time, the multimedia terminal serves as the synchronous host machine, and periodically transmits synchronizing information to the local area network; (3) and every time the multimedia terminal transmits synchronizing information, the age of the synchronous host machine increases by 1. The invention effectively overcomes the defects of high dependence, no adaptability, high cost and maintenance expense, and the like for auxiliary apparatus, such as a clock source generating apparatus and the like, when the multimedia terminal carries out synchronization under the prior technical conditions.
Description
technical field [0001] The invention relates to the field of multimedia, in particular to a multimedia terminal synchronization technology, and proposes a method for synchronizing a multimedia terminal. Background technique [0002] In many multimedia playback applications, multiple multimedia terminals are required to synchronize the playback progress, but in fact, due to factors such as device differences between multimedia terminals and software running on hardware platforms affected by random events, the It is impossible to achieve synchronization on the playback content, so some technical innovations are needed to solve this problem. [0003] The traditional synchronization method is to set up a clock source device in the application system, and the clock source device sends a synchronization signal associated with the playback progress to all player terminals in the system, and each multimedia terminal automatically adjusts itself after receiving the clock signal.
