Transmission device, DP source device, reception device, and DP sink device
A transmission device includes a converter and a transmitter. The converter converts a plurality of link symbols in DisplayPort (DP) into a data block in Gen 2 in Universal Serial Bus (USB). The transmitter transmits the data block.
1. A transmission device comprising:
circuitry configured to
convert a plurality of link symbols containing a control symbol to which no ANSI 8b/10b special code is allocated in DisplayPort (DP) into a data block in Gen 2 in Universal Serial Bus (USB); and
transmit the data block to a reception device configured to convert the data block to the plurality of link symbols.
2. The transmission device according to claim 1 , wherein the circuitry is configured to:
scramble the data block; and
transmit the scrambled data block to the reception device.
3. A DisplayPort (DP) source device comprising:
circuitry configured to
map stream data to a plurality of link symbols containing a control symbol to which no ANSI 8b/10b special code is allocated in DisplayPort (DP);
convert the plurality of link symbols into a data block in Gen 2 in Universal Serial Bus (USB); and
transmit the data block to a DisplayPort (DP) sink device configured to convert the data block to the plurality of link symbols.
4. A reception device comprising:
circuitry configured to
receive, from a transmission device, a data block obtained as a data block in Gen 2 in Universal Serial Bus (USB) by conversion, by the transmission device, from a plurality of link symbols containing a control symbol to which no ANSI 8b/10b special code is allocated in DisplayPort (DP); and
convert the received data block into the plurality of link symbols.
5. The reception device according to claim 4 , wherein the circuitry is configured to:
de-scramble the received data block; and
convert the de-scrambled received data block into the plurality of link symbols.
6. A DisplayPort (DP) sink device comprising:
circuitry configured to
receive, from a DisplayPort (DP) source device, a data block obtained as a data block in Gen 2 in Universal Serial Bus (USB) by conversion, by the DisplayPort (DP) source device, from a plurality of link symbols containing a control symbol to which no ANSI 8b/10b special code is allocated in DisplayPort (DP);
convert the received data block into the plurality of link symbols; and
map the plurality of link symbols converted from the received data block to stream data.
7. The reception device according to claim 5 , wherein the circuitry is configured to discard the control symbol from the plurality of link symbols when converting the de-scrambled received data block into the plurality of link symbols.
8. The DIP sink device according to claim 6 , wherein
the circuitry is configured to discard the control symbol from the plurality of link symbols when mapping the plurality of link symbols to the stream data.
