Abstract: Embodiments of the invention are generally directed to video frame synchronization. An embodiment of a method includes receiving a first video data stream from a first source at a first port of a multi-port device, a first video frame of the first video data stream arriving at the first port at a first arrival time, and receiving a second video data stream from a second source at a second port of the multi-port device, a second video frame of the second video data stream arriving at the second port at a second arrival time. The method further includes determining an offset between the first arrival time and the second arrival time, determining one or more correction factors based at least in part on the offset, the one or more correction factors including a first correction factor for the first source, and sending a first command to the first source to modify a time of transmission by the first source of a third video frame following the first frame using the correction factor.

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.

Abstract: Embodiments of the invention are generally directed to messaging to provide data link integrity. An embodiment of a method includes transmitting a data stream over a data link from a first device to a second device, the data stream including multiple frames, the data stream being transmitted in a first mode. The method further includes determining a data transmission mode change from the first mode to a second mode for the transmission of the data stream from the first device to the second device, generating mode packets, each mode packet including fields to define a plurality of mode elements, the fields of the mode packet being set to indicate the data transmission mode change, and transmitting the mode packets to the second device prior to implementing the data transmission mode change.
