The choice of interface is specified during hardware resets. NETWORK INTERFACE Data is organized in frames which are transmitted at the system sampling frequency. Frames contain source and control information and are further divided into sub-frames of 8 bytes fields. At the physical level, data is transferred as serial bits with biphase encoding. THE D2B PROTOCOL The Digital Data Bus (D2B) is a networking protocol for automotive multimedia data communication integrating digital audio, video and other high data rate synchronous or asynchronous signals, with the control data for network management protocols and APIs. The protocol enables robust single cable interconnection and compatible interoperation of in-car AV multimedia and ITS devices, such as Radio Head Units, CD Changer, CD-ROM, GPS Navigation, Voice Control, Car Telephones, TV and others. LCD DISPLAY MOBILE TELEPHONE RADIO HEAD-UNIT GPS ENGINE DVD PLAYER VOICE I/O DSP AMPLIFIER VEHICLE EMERGENCY SYSTEM (VEMS) FIXED TELEPHONE HANDSET CD-CHANGER Control data is constructed into a control frame, which is transferred at a rate of two bits per sub-frame. The control frame comprises 128 bits and requires a block of 48 frames to transmit. SOURCE DATA PORTS Six source data ports are provided, giving the flexibility for multiple data Electrical Bypass Source Data Bypass L RX 64-bit input shift register D0 D1 D2 D3 D4 D5 D6 D7 D0 D1 D2 D3 D4 D5 D6 D7 L 64-bit output shift register TX All data ports share a common frame synchronization and serial bit clock. Data can be arranged as Philips I2S, Sony or Matsushita, 16 or 24 bit serial formats. Additionally, SR0 and SX0 can be configured for operation as an IEC-958 (or SPDIF) interface. Source and destination data is routed between the source data ports and the network interface via the Routing Information Table. This allows all data bytes coming from either the network receiver or source input ports to be rearranged, mixed and re-directed to the network transmitter or source output ports.
