Abstract:
1. A computer device comprising: a data packet buffer to store received data packets of a plurality of data streams; an improving quality packet buffer to store an improving quality packet, the improving quality packet including redundant data to recover a lost data packet of a first one of the data streams and identification information to identify one or more of the received data packets used for generating the redundant data; an improving quality processing unit to detect a data packet of the received data packets stored in the data packet buffer, the detected data packet corresponding to the improving quality packet and being identified based on the identification information; a correspondence memory to store a correspondence between the improving quality packet and the detected data packet; an operation controller to issue, when the first one of the data streams is selected, an instruction of improving quality processing to recover the lost data packet; and a recovered data packet processing unit to process the recovered data packet; wherein the improving quality processing unit performs, when receiving the instruction from the operation controller, the improving quality processing to recover the lost data packet, using the redundant data in the improving quality packet and the data packet identified by the correspondence.
