Streaming Video with Optimized Reconstruction-Based DCT
One fundamental problem with streaming video data over unreliable IP networks is that packets may be dropped or arrive too late for real-time playback. Traditional error-control schemes are not attractive because they either add redundant information that may worsen network traffic, or rely solely on decoders with inadequate error concealment. This paper presents a joint senderreceiver approach in designing transforms for multiple-description coding in order to conceal network losses in streaming real-time video over the Internet. In the receiver side, we adopt a simple interpolation-based reconstruction, as sophisticated concealment techniques cannot be employed in software-based real-time playback. In the sender side, we design an optimized reconstructionbased discrete cosine transform (ORB-DCT) with the objective of minimizing the mean squared error, assuming that some of the descriptions are lost and that the missing information is reconstructed by simple averaging at the destina...
