Abstract
Methods for increasing encryption synchronization availability include collecting encryption synchronization data from a first superframe received at a gateway. The encryption synchronization data is for decrypting media in a second superframe also received at the gateway. The encryption synchronization data from the first superframe is used to form a composite encryption synchronization codeword for decrypting media in a third superframe formed by the gateway, wherein the third superframe includes the composite encryption synchronization codeword and at least a portion of the media from the second superframe. The third superframe is sent to a receiving device so that media in the third superframe can be decrypted by the receiving device using the composite encryption synchronization codeword that is included in the same superframe as the media that is being decrypted.
