36、ctrical characteristics for the Domestic Digital Bus (D2B) System. The audio-video cluster (TV set, VCR, etc.) needs a practical bus for interconnecting devices and exchanging messages. D2B was developed for this purpose. The capabilities of D2B can be described as follows: It is appropriate for aud
37、io and video, for controllers and for home computers. It can be used as a local independent system for this application or as an audio, video and control subsystem connected via an appropriate gateway to a main bus. Following the same scheme, D2B can also be used as a local independent system or as
38、an integrated subsystem for any other application. In order to allow exchange of digital data in a system made up of devices of various manufacturing origins, it is necessary to have a “standardized communication protocol” suitable for the specific needs of this system. Within the Home Electronic Bu
39、s environment (HEB), D2B can be used as a subsystem. For this reason, the address and command tables for audio, video and control are harmonized with those of the Japanese Home Bus (HBS) and of the European Home Bus (IHS). The structure of the Domestic Digital Bus (D2B), the transmission speeds, the
40、 format and the structure of the frames have therefore been chosen to meet the requirements of the home and small office application area. See Figure 1. In the D2B system, devices perform as masters and slaves during data transfers. A master device is able to initiate and control a data transfer usi
41、ng D2B. Depending on the direction of transfer, devices also perform as transmitters or receivers. The D2B is a multi-master bus, which means that any device capable of controlling the bus can do so. D2B is based on Carrier Sense Multiple Access with Collision Detection (CSMA/CD) with arbitration, b
42、ased on the unique identification of each device. Each transfer is restricted in time to avoid monopolisation of the bus. The bus allows a self-configuring network to be built up. D2B allows devices to contain a number of sub-devices. 2 Normative reference The following standard contains provisions

45、993 4 BSI 01-2000 3 Definitions and abbreviations 3.1 Definitions For the purposes of this International Standard, the following definitions apply: frame block of information, transferred across the D2B data link. The frame consists of the header field, the master address field, the slave address fi
46、eld, the control field and the message field header field field indicating the start of a frame and identifying the mode of a frame (transmission speed) master address field field identifying the device which seeks to take control, this being called the “Master” slave address field field identifying
47、 the device addressed by the master, this being called the “Slave” control field field controlling the direction of the message and defining the interpretation of the message message field field containing data bytes which carry the message master (during a particular frame) device that initiates a
48、D2B frame and controls its timing. Several masters may simultaneously try to initiate a frame, but only one of these masters can gain exclusive access to the medium for the duration of a frame, i.e.be the winning master. D2B devices may or may not be capable of master operation slave (during a parti
49、cular frame) device that responds to a D2B frame, initiated by a master, after being addressed in that frame. All devices capable of slave operation, shall accept and interpret all frames, at least up to and including the slave address field. D2B devices may or may not be capable of slave operation transmitter (during a particular frame) device that transmits the information content of the data fields in that frame. In a D2B frame, either the master or the slave can be the t
