Abstract
Embodiments relate to sending vertical synchronization data for a plurality of data streams in a selected data stream to perform authentication operations for the plurality of data stream. A port processor receives data streams from a plurality of transmitting devices. After receiving the data streams, the port processor selects one of the data streams for transmission to a decrypting device. The port processor extracts vertical synchronization data from the unselected data streams and inserts the extracted vertical synchronization data into the selected data stream to form a modified data stream. The port processor sends the modified data stream to a decrypting device. The decrypting device has at least one processing engine. The port processor discards the unselected data streams without sending the unselected data streams to the decrypting device.
