Abstract: Technologies for recovering from dropped frames in the real-time transmission of video over an IP network are provided. A video streaming module receives a notification from a receiving module that a data packet has been lost. The video streaming module determines, based on the type of video frame conveyed in the lost packet and the timing of the lost packet in relation to the sequence of video frames transmitted to the receiving module, whether or not a replacement video frame should be sent to the receiving module. If the video streaming module determines a replacement video frame is warranted, then the video streaming module instructs a video encoding module to generate a replacement video frame and then transmits the replacement video frame to the receiving module.

Abstract: Deciphering and verification of the checksum of enciphered and encapsulated UDP datagrams, particularly those which enclose a tunneling protocol such as L2TP, are achieved by the provision of a checksum verifier in parallel with a decipher block. Checksum logic creates a pseudo UDP header needed for checksum verification using fields that would occur at the start of the packet that encapsulates the UDP datagram. The first part of the packet to be deciphered is the UDP header; checksum logic can latch the checksum field into a local register. As the rest of the packet is deciphered the checksum verifier processes the data at the same time. Eventually the checksum logic will acquire a complete checksum which can be compared with the checksum that had been previously latched, so as to verify the checksum.
