摘要: A wireless content protection system includes a coordinator, a source device, and a sink device. The coordinator includes a scheduler. The source and sink devices each have a content protection manager. One of the content protection manager allocates and releases bandwidth via the coordinator for a test message and a response message for a round-trip time computation. The test message is transmitted in a source-to-sink channel time block. The response message is transmitted in a sink-to-source channel time block. The round-trip time is the period between the end of the source-to-sink channel time block and the beginning of the sink-to-source channel time block.

摘要: A media access controller (MAC) generates a composite packet having an optimized format for carrying audio, video, and data traffic. A header portion of the composite packet is encoded separately from a data portion of the composite packet. A physical device interface (PHY) is coupled to the MAC. The PHY encodes and decodes between a digital signal and a modulated analog signal. The PHY comprises a high rate physical layer circuit (HRP) and a low rate physical layer circuit (LRP). A radio frequency (RF) transmitter is coupled to the PHY to transmit data.
