Abstract
Official abstract text for this publication.
An electronic apparatus includes a first communication unit configured to perform I2C bidirectional communication with an external apparatus using two signal lines included in a transmission path as I2C communication lines, a second communication unit configured to perform bidirectional differential communication with the external apparatus using the two signal lines as high-speed data communication lines, a switching unit configured to select a first communication state in which the first communication unit is connected to the two signal lines or a second communication state in which the second communication unit is connected to the two signal lines, and a controller configured to control operation of the switching unit.
First claim
Opening claim text (preview).
What is claimed is: 1. An electronic apparatus comprising: a first communication unit configured to perform Inter-Integrated Circuit (I2C) bidirectional communication with an external apparatus using two signal lines included in a transmission path as I2C communication lines; a second communication unit configured to perform bidirectional differential communication with the external apparatus using the two signal lines as bidirectional differential communication lines; a switching unit configured to select a first communication state in which the first communication unit is connected to the two signal lines or a second communication state in which the second communication unit is connected to the two signal lines; and a controller configured to control operation of the switching unit. 2. The electronic apparatus according to claim 1 , wherein a data transmission unit of the electronic apparatus is compatible with High Definition Multimedia Interface (HDMI) interface. 3. The electronic apparatus according to claim 2 , wherein the two signal lines comprises a serial data (SDA) line and a serial clock (SCL) line of a High Definition Multimedia Interface HDMI standard. 4. The electronic apparatus according to claim 1 , wherein the switching unit includes a first transistor used to connect the first communication unit and the two signal lines to each other and a second transistor used to connect the second communication unit and the two signal lines to each other.
