  • Publication number: 20150215058
    Abstract: A mechanism for facilitating dynamic counter synchronization and packetization for data streams being communicated over communication devices is described. In one embodiment, a method includes detecting an audio/video (A/V) data stream being encrypted and/or decrypted using one or more high-bandwidth digital content protection (HDCP) engines, where the A/V data stream is communicated between a source device and a sink device. The method may further include dividing a video stream portion of the A/V data stream into a plurality of frames if the A/V data stream relates to a high-definition multimedia interface (HDMI), and synchronizing counter values with indicators within the plurality of frames.
