Recently digital signage improves the differentiation by way of pseudo enlargement that displays one content divided into plural monitors and/or increase of contact time by displaying the same content with the plural monitors on the line of flow of the person along with the popularization. On the other hand, wireless contents distribution to digital signage devices is desired according to demand for cable cost reduction or frequent layout change. In this paper, we propose a synchronization method to utilize unlicensed-band wireless and NTP, which enables each signage internal timer to synchronize system master clock less than millisecond order accuracy of one or less video frame. And we evaluate our proposed method by experimental prototype implementation. |
