Embodiments of systems and methods for forward channel contextual error concealment and sync for virtual, augmented, or mixed reality (xR) content in connectivity-constrained environments are described. In some embodiments, a Head-Mounted Device (HMD) may include a processor; and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the HMD to: decode content received from an Information Handling System (IHS) coupled to the HMD; and handle an error in the decoded content using context information received from a sensor mounted on the HMD.
