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 method for transcoding data comprises receiving an input stream of data formatted according to a USB standard, the input stream is partitioned into a sequence of blocks having a fixed length. At least one input block of the input stream comprises one or more data symbols and one or more control symbols, the one or more control symbols include one or more general control symbols. The method also includes transcoding the at least one input block to generate at least one output block comprising a synchronization block and a control/data block. The control/data block comprises the one or more data symbols of the at least one input block, a representation of the one or more general control symbols of the at least one input block, and a plurality of indicators indicating locations of the one or more data symbols and control symbols in the at least one input block.

摘要： Network nodes acquire bandwidth in contention-based networks for handling video traffic. A request to reserve a channel for transmission of a payload is sent prior to a network node receiving the payload. The payload is a burst of video data that is generated periodically. A network node determines a time period for reserving the channel. The network node determines when to initiate contending for the channel and the time period for transmitting the payload to another network node. A network node determines when a payload is expected to arrive and monitors its back off time period at least a time period prior to receiving a payload. The network node also monitors transmission of the payload and adjusts when to initiate contending for the channel.

摘要： Embodiments relate to customizing contents displayed at a sink device by converting received contents from a source device. The source device provides, to the sink device, the contents and display information of the source device. The display information of the source device may indicate spatial arrangements (e.g., locations and sizes) of the contents in the source device. The sink device may map sub-display regions of the source device to sub-display regions of the sink device. Moreover, the sink device generates output images for display in sub-display regions of the sink device according to the mapping. By mapping display regions at the sink device, images can be displayed in different arrangements at the sink device without the source device having any information on the configuration of sub-display regions of the sink device.

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.
