HDMI® Latency Indication Protocol (LIP)
• LIP improves audio and video synchronization, especially for multiple-hop system configurations such as those with an audio video receiver or soundbar
• Based on demand for sync improvements as content, distribution, devices and installations have become more diverse and demanding
• Whether it is the obvious lag between a person’s lip movements and hearing the words, or fast-paced gaming interactions - the out-of-sync experience is a distraction and can make content unwatchable
• This can be even worse when a system involves multiple audio and video connections
