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.


A source device receives digital data comprising uncompressed video data and its associated metadata and compresses the video data. The source device generates an error code for each data word representing the compressed video data and its associated metadata. The data word and its corresponding error code are combined to form a code word. The source device organizes code words of the video data and its metadata into orthogonal data blocks and transmits the data blocks to a sink device. The sink device decodes corrupted data bits in the received data based on analysis of the error codes of the code words in the data blocks. Organizing code words into orthogonal data blocks helps isolate corrupted data bits in data blocks and enables the sink device to detect and correct corrupted data bits resulting from a single transmission error and to detect corrupted data bits resulting from multiple transmission errors.

Embodiments of the invention are generally directed to a single-ended configurable multi-mode driver. An embodiment of an apparatus includes an input to receive an input signal, an output to transmit a driven signal generated from the input signal on a communication channel, a mechanism for independently configuring a termination resistance of the driver apparatus, and a mechanism for independently configuring a voltage swing of the driven signal without modifying a supply voltage for the apparatus.

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.

The discovery of a topology of a network with an unknown topology can enable the selection of a data path within the network, and the establishment of a data stream over the selected data path. Routing tables mapping originating nodes to input ports can be created based on the receipt of discovery messages generated by the originating nodes. A source node can select a data path between the source node and a sink node in order to establish a data stream using the routing tables. Data paths can be selected based on, for instance, routing table bandwidth information, latency information, and/or distance information. Data streams can be established over the selected data path, and each node can release any reserved output bandwidth determined to be unnecessary for the data stream.
