本人有一波兰朋友，需要采购：基于以太网，可以通过IP传输声音和视频信息的模块。 可以供应此产品的朋友，请加我的qq，我会把客户的联系方式给你，由你本人直接联系。凑热闹的朋友勿扰，谢谢！ 朋友的原文技术要求如下： do you know good and trustworthy manufacturer of digital equipment, as Ethernet switches, VOIP solutions and similar? we are looking for customized module working on Ethernet basis to send voice and video signal... via IP... we are looking for module, made for us, working as gate between analog for audio and video signals, to send this signals via Ethernet IP system it's very simple block diagram just to show what we need this module should has also Ethernet switch build into we have analog signal in and out, and PAL video analog signa in and out we have analog signal in and out, and PAL video analog signa in and out we want to send fhis signals via IP to second same module. Thats all... of course video signal should be a little compressed, and for audio signal echo cancellation is needed from our microcontorller we will load destination address for voice and video packets and we should have possibility to send some digital data to derfined IP (or MAC) address because it's a part of wider network switch to properly route IP packets is necessery. we need this module for our communication module for our videodoorphone system audio/video IP gate?it could be name of project.
