Zusammenfassung:	A remote management controller may include a video redirection device and a processor. The video redirection device may be configured to: obtain a slice of video data output from a video graphics controller; calculate at least one value correlative to the slice of video data; and if the calculated value for any portion of the slice differs from a value for a previously obtained corresponding portion, update a table associated with an image related to a remote system with the calculated value, and process the portion of the slice to create a data portion of a network packet in a network buffer. The processor may be configured to: allocate the network buffer; and provide a header portion of the network packet to the network buffer.
