1. A computer-implemented method, comprising: receiving, by a computing system, a data stream of encoded packetized content; identifying, by the computing system, a particular encoded packet of the data stream as having video content that requires electronic scrambling prior to export from the computing system to a different computing system; determining, by the computing system, a particular threshold value that defines allowable spatial frequencies of video content within the particular encoded packet, the threshold associated with the export of packetized content from the computing system to the different computing system; and modifying, by the computing system, discrete cosine transform (DCT) coefficients of the particular encoded packet that exhibit a matrix column or row index value greater than the particular threshold value to zero magnitude, without completely decoding the particular encoded packet.
