The method includes sending compressed video data including a reference frame message to create a long term reference frame to a plurality of decoders at one or more destination points, receiving feedback from the decoders indicative of whether or not the decoders successfully received the reference frame message, and in the case that the received feedback is such that at least one of the decoders did not successfully receive the reference frame message or does not have the indicated recent frame, repeating sending a reference frame message to create the long term reference frame. Using the method can replaces I-frame error recovery with long term reference frames, even in the case where the reference frame management messages are lost to at least one decoder."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Long term reference frame management with error video feedback for compressed video communication","description":"An apparatus, software encoded in tangible media, and a method at an encoder.
