Embodiment Construction

[0028] When this application describes a plurality of exemplary embodiments, it should be understood that this application can be implemented in various ways, and this application is not limited to the specific examples described below, any features or specific aspects implemented by specific examples.

[0029] FIG. 1 shows a schematic diagram of a multimedia synchronization system 100 according to an embodiment of the present invention. The multimedia synchronization system 100 is located in a wireless local area network (WLN). The multimedia synchronization system 100 includes a first speaker 101, a second speaker 102, a third speaker 103 and a fourth speaker 104. The speakers 101, 102, At least one speaker in 103, 104 includes the function of a wireless network access point AP. In this embodiment, the first speaker 101 is selected as a wireless network access point AP, and the first speaker 101 is used to provide a beacon (beacon) TS, wherein the beacon TS includes a timest...

Abstract

The invention provides a multimedia synchronizing system and a multimedia synchronizing method applied to a wireless local area network. The multimedia synchronizing system comprises a first horn and a second horn. The first horn is used for sending a beacon in a wireless manner, wherein the beacon includes a time stamp. The second horn is connected with the first horn via the wireless local area network for receiving the beacon sent by the first horn, and being synchronous with the first horn according to the time stamp included by the beacon.

Description

technical field [0001] This case is about a multimedia synchronization system and method; especially about a multimedia synchronization system and method applied to a wireless area network. Background technique [0002] Generally, when an audio player processes an audio stream for playback, it controls the time of each audio sample data (audio sample) according to the sampling rate described by the audio stream, so as to achieve the purpose of smooth playback. And to allow more than two audio players to play out the same section of audio synchronously at the same time, it is necessary to allow the audio players to play out the same audio sample data at the same time. [0003] In the prior art, the commonly used method is that the audio player uses the network time protocol / simple network time protocol (network time protocol / simple network time protocol, NTP / SNTP) mechanism to make the system time of each audio player unanimous. Then, when the audio player processes the aud...
