FIG. 14 shows a detailed configuration example of the receiver of the MHL receiving unit 205. The receiver includes deserializers 221-1 to 221-N, TMDS decoders 222-1 to 222-N, a combining unit 223, and an MHL data decomposing unit 224. Each of the deserializers 221-1 to 221-N deserializes N series TMDS line data as a reception signal and converts the data into N series TMDS signals.

TMDS decoders 222-1 to 222-N respectively convert N-series TMDS signals into TMDS line data. The synthesizing unit 223 determines TMDS data channels to which the N-sequence TMDS line data corresponds, based on channel number data inserted in the control section. Then, the synthesizing unit 223 rearranges and synthesizes the TMDS line data of 0 to (N−1) as necessary based on the discrimination signal to obtain MHL data. The MHL data decomposition unit 224 decomposes the MHL data to obtain video data, audio data, a control signal, and the like.

The flowchart of FIG. 15 schematically shows transmission / reception processing of MHL data in the MHL transmission unit 109 and the MHL reception unit 205. In step ST1, processing is started. In step ST2, the MHL transmitting unit 109 and the MHL receiving unit 205 establish communication with CBUS to establish an MHL link.

Next, in step ST3, the MHL transmission unit 109 distributes the MHL data to a plurality of series of TMDS line data corresponding to a plurality of TMDS data channels, and each TMDS line data has an ID (channel number data + total number). Channel number data) is inserted and transmitted.

Next, in step ST4, the MHL receiving unit 205 determines the corresponding TMDS data channel based on the ID inserted in each received TMDS line data, and each TMDS line data based on the determination result. Are rearranged and synthesized as necessary to obtain MHL data. After step ST4, the process ends in step ST5.

As described above, in the image display system 10 shown in FIG. 1, the first to x-th terminals (pins) are respectively provided on the A-side surface and the B-side surface of the opening 402 of the receptacle 400. ) Is arranged. Also, the first to xth terminals are arranged on one surface of the flat pin support 502 of the plug 500. Therefore, for example, a reversible connector can be realized with a simple configuration.

Further, in the image display system 10 shown in FIG. 1, the functions of the first to xth terminals are the same as the functions of the xth to first terminals, respectively, and the A plane side of the opening 402 of the receptacle 400. The first to x-th terminals disposed on the surface of the second terminal are respectively connected to the x-th to first terminals disposed to face the surface on the B-side. Therefore, for example, the terminal shape of the receptacle becomes simple, and the manufacture becomes easy.

In the image display system 10 shown in FIG. 1, when the MHL transmission unit 109 of the mobile phone 100 distributes MHL data to a plurality of TMDS line data and transmits the data using a plurality of TMDS channels, the MHL transmission unit 109 The identification information for identifying the corresponding TMDS data channel is inserted into the control period of each TMDS line data. On the other hand, the MHL receiving unit 205 of the television receiver 200 determines the TMDS data channel corresponding to each series of data included based on the identification information inserted in the control period of each TMDS line data, and the determination result Based on the above, each TMDS line data is rearranged and synthesized as necessary to obtain MHL data.

Therefore, in the image display system 10 shown in FIG. 1, it is possible to support a reversible connector (receptacle 400, plug 500). For example, as shown in FIG. 16A, when both the transmitting side and the receiving side are inserted in the A plane of the plug 500 and are in the forward connection state, the TMDS channel 1 output from the output (1) of the MHL transmitting unit is supported. The TMDS line data (1) passes through the receptacle pin (1) and the MHL cable plug pin (1) on the MHL source device side, and the MHL cable plug pin (1) and receptacle on the MHL sink device side. Through the input (1) of the MHL receiver. The MHL receiving unit determines that the TMDS line data (1) corresponds to the TMDS channel 1 from the inserted ID, and processes it as TMDS line data corresponding to the TMDS channel 1.

Also, for example, as shown in FIG. 16 (b), when the B side of the plug 500 is inserted only on the receiving side and the connection is in the reverse direction, it corresponds to the TMDS channel 1 output from the output (1) of the MHL transmitter. TMDS line data (1) passes through the receptacle pin (1) on the MHL source device side and the pin (1) on the MHL cable plug, and on the MHL sink device side, the pin (1) on the MHL cable plug and the receptacle It passes through the pin (X) and enters the input (X) of the MHL receiver. The MHL receiving unit determines that the TMDS line data (1) corresponds to the TMDS channel 1 from the inserted ID, and processes it as TMDS line data corresponding to the TMDS channel 1.

Also, for example, as shown in FIG. 16 (c), when the B-side insertion of the plug 500 is made only on the transmission side and the reverse connection state is established, it corresponds to the TMDS channel 1 output from the output (1) of the MHL transmission unit. TMDS line data (1) passes through the receptacle pin (1) and the pin (X) of the MHL cable plug on the MHL source device side, and the pin (X) of the MHL cable plug and the receptacle pin on the MHL sink device side. It passes through the pin (X) and enters the input (X) of the MHL receiver. The MHL receiving unit determines that the TMDS line data (1) corresponds to the TMDS channel 1 from the inserted ID, and processes it as TMDS line data corresponding to the TMDS channel 1.

In this manner, the MHL receiving unit 205 determines which TMDS line data each TMDS line data entering the inputs (1) to (X) corresponds to based on the ID, and rearranges and processes them as necessary. Therefore, even if the TMDS line data (1) to (x) are not correctly entered in the inputs (1) to (X) of the MHL receiving unit, the MHL data can be properly restored.
