Port Processor Capable of Performing Authentication for Multiple Source Devices

摘要

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.

1. A method comprising:
receiving a plurality of data streams from a plurality of transmitting devices; selecting one data stream from the plurality of data streams for transmission to a decrypting device; extracting vertical synchronization data from unselected one or more data streams; inserting the extracted vertical synchronization data into the selected data stream to generate a modified data stream; sending the modified stream to a decrypting device including at least one processing engine for decrypting the selected data stream; and discarding the one or more unselected data streams without sending the one or more unselected data streams to the decrypting device.
