Zusammenfassung:One or more system, apparatus, method, and computer readable media is described for reducing the GOP length during a direct pass-through of an encoded video stream format that is supported by the decoder at the sink. In some embodiments, the encoded video stream is decoded on the source device and employed to generate and insert supplemental intra-predicted frames (I-frames) at shorter intervals allowing for faster recovery in the event of lost packets/frames when transmitted to a sink display. In some embodiments, Residual Artifact Suppressed (RAS) inter-predicted frames are further created and inserted in place of any frames that reference a frame converted to a supplemental I-frame. The encoded video stream passed through will consist of all the original frames except for the supplemental I-frames reducing the GOP, and RAS inter-predicted frames modified to prevent propagation of residual induced artifacts.
