dividing each frame in a video stream portion of the A/V data stream into a plurality of packets; and

inserting a special packet including counter values between an active edge of a vertical synchronization signal and an indicator indicating whether a subsequent frame is encrypted, wherein the special packet is inserted between consecutive packets of the plurality of packets.

8. The method of claim 7 , wherein the one or more HDCP engines include one or more HDCP 2.2 engines.

9. The method of claim 8 , wherein each counter value at a receiver is synchronized with a counter value at a transmitter based on the special packet.

10. The method of claim 7 , wherein the A/V data stream relates to a mobile high-definition link (MHL), wherein the MHL includes MHL3.

11. The method of claim 7 , further comprising delivering the special packet to a corresponding location with the A/V data stream, wherein the special packet is delivered between the active edge of the vertical synchronization signal and the indicator to synchronize counter values at the source device and counter values at the sink device.

12. The method of claim 10 , further comprising displaying the A/V data stream at a display device, wherein the A/V data stream is communicated between the source device and the sink device over a network,

wherein the sink device comprises one or more of a television, a cinema display, a projector, a Digital Versatile Disk (DVD) player, a Blu-ray player, a computing device, a smartphone, a Personal Digital Assistant (PDA), a game console, a docking station, a cable adapter, and a dongle,

wherein the source device comprises one or more of a network computing system, a cable set-top box, a cable headend, a satellite broadcasting system, a Blu-ray player, a DVD player, a smartphone, and a PDA,

wherein the network comprises one or more of a broadcasting network, a Local Area Network (LAN), a Wide Area Network (WAN), a Personal Area Network (PAN), a Metropolitan Area Network (MAN), an intranet, an Internet, a cloud-based network, and a shared-channel network including a High-Definition Multimedia Interface (HDMI), a Mobile High-Definition Link (MHL), a DisplayPort, a Universal Serial Bus (USB), a Peripheral Component Interconnect (PCI), and an on-chip bus including Advanced Microcontroller Bus Architecture (AMBA).
