摘要： Embodiments relate to sending vertical synchronization data for a plurality of data streams in a selected data stream to perform authentication operations for the plurality of data stream. A port processor receives data streams from a plurality of transmitting devices. After receiving the data streams, the port processor selects one of the data streams for transmission to a decrypting device. The port processor extracts vertical synchronization data from the unselected data streams and inserts the extracted vertical synchronization data into the selected data stream to form a modified data stream. The port processor sends the modified data stream to a decrypting device. The decrypting device has at least one processing engine. The port processor discards the unselected data streams without sending the unselected data streams to the decrypting device.

摘要： In one aspect, a video processing device includes a processor and a transmitter, for example implemented as separate integrated circuits on a printed circuit board. Pins on the processor are coupled to pins on the transmitter via a data channel, for example conductive leads on the printed circuit board. Video data is transmitted from the processor to the transmitter via this data channel, which is high speed enough to accommodate video data. The transmitter also includes an encryption engine used to encrypt the video data. Encryption control data, which determines the encryption to be applied, is transmitted from the processor to the transmitter over the same data channel as the video data. This is more secure than transmitting the encryption control data over a slower separate data channel, because the high speed video channel is harder to tamper with.

摘要： 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.

摘要： Techniques and mechanisms for formatting digital audio-video (“AV”) information. In an embodiment, interface logic includes circuitry to receive digital AV information which, in one or more respects, is according to or otherwise compatible with a first interface specification. The interface logic changes a format of the digital AV information to allow for subsequent physical layer processing which is according to a second interface specification. In another embodiment, conversion logic receives analog signals according to the second interface specification and, based on such analog signals, performs digital information processing for subsequent generation of other analog signals to be transmitted according to the first interface specification.

摘要： A system for receiving and decrypting media content encrypted according to the HDCP protocol is described herein. A receiving device coupled to a plurality of content channels includes an authentication engine to authenticate each content channel and to generate an initial session key associated with each authenticated content channel. The content channels can be, for example, an HDMI channel or an MHL3 channel. A session key indicator indicating a session key used to encrypt media content is received, and an updated session key is generated. The receiving device also includes a stream cipher engine configured to decrypt received encrypted media content using the updated session key. Decrypted media content can then be displayed, for instance on a display of the receiving device.

摘要： Embodiments relate to routing encrypted data from a source to a sink via a router without decrypting the data in the router. The source authenticates with the router, the result of which produces a session key and a pseudo-random number. The router authenticates with the sink using the same session key and pseudo-random number. The router passes encrypted data received from the source to the sink without decryption and re-encryption.

摘要： Embodiments relate to half-duplex bidirectional transmission of data compliant with a first standard (e.g., Universal Serial Bus (USB) standard) over a physical channel of a multimedia link for transmitting audio/video (“A/V”) data compliant with a second standard (e.g., Mobile High-Definition Link (MHL) standard) between a source device and a sink device using time division multiplexing (TDM). The source device sends units of data including A/V data and forward data compliant with the first standard at first times whereas the sink device sends units of data including backward data compliant with the first standard at second times between transmissions from the source device. The first times do not overlap with the second times. Synchronization signals may be added to the first and second units of data to align character symbols embedded in the first and second units of data.
