33、tronic audio/video equipment using IEEE 1394. It describes the general packet format, data flow management and connection management for audio-visual data, and also the general transmission rules for control commands. The object of this standard is to define a transmission protocol for audio-visual

34、data and control commands which provides for the interconnection of digital audio and video equipment, using IEEE 1394. 2 Normative references The following referenced documents are indispensable for the application of this document.

40、et the performance criteria specified by IEEE 1394. Either the cable and connector defined in IEEE 1394:1995, or the cables and connector defined in IEEE 1394a:2000, shall be used. When necessary for an AV device to generate a bus reset, it shall follow the requirements of IEEE 1394a:2000, 8.2.1. An

41、 AV device that initiates a bus reset should generate an arbitrated (short) bus reset, as specified by IEEE 1394a:2000, in preference to the long bus reset defined by IEEE 1394:1995. 4.2 Link layer All link layer implementations conforming to this standard shall meet the specifications of IEEE 1394.

42、 4.3 Transaction layer All transaction layer implementations conforming to this standard shall meet the specifications of IEEE 1394. 5 Minimum node capabilities A node shall conform to the following requirements. A node shall be cycle master capable. This is because every node has the possibility to

43、 be assigned as a root. A node shall be isochronous resource manager capable, as specified by IEEE 1394:1995, and shall implement the additional isochronous resource manager facilities and responsibilities specified by IEEE 1394a:2000 in 8.3.1.5, 8.3.2.3.8, 8.3.2.3.11, 8.4.2.3 and 8.4.2.6A. A node w

44、hich transmits or receives isochronous packets shall have plug control registers (see 7.2). 5.1 Serial bus management Bus manager capability is optional for AV devices, but, if implemented by devices conforming to this standard, shall conform to IEEE 1394. 5.2 Command and status registers 5.2.1 CSR

45、core registers This standard conforms to the CSR architecture. Details of its registers are specified by IEEE 1394. The STATE_CLEAR.cmstr bit shall be implemented as specified by IEEE 1394a:2000, 8.3.2.2.1. BS EN 61883-1:200961883-1 IEC:2008(E) 9 NOTE The cmstr bit is set automatically (see IEEE 139

46、4a:2000, 8.3.2.2.1) by system software or hardware when a node becomes the new root after the bus reset process is completed. In this manner, it is possible to ensure the fast resumption and continuity of data transmission where the time scale is critical at the level of microseconds. The rapid acti

47、vation of a new cycle master decreases the likelihood of a gap in the transmission of cycle start packets; uninterrupted transmission of cycle start packets at nominal 125 s intervals is critical to the delivery of isochronous data within its latency requirements. 5.2.2 Serial bus node registers Imp

48、lementation requirements for bus-dependent registers in this standard conform to IEEE 1394. A node shall have the following registers: CYCLE_TIME register BUS_TIME register BUS_MANAGER_ID register BANDWIDTH_AVAILABLE register CHANNELS_AVAILABLE register A node should have the following register spec

49、ified by IEEE 1394a:2000: BROADCAST_CHANNEL register 5.2.3 Configuration ROM requirements A node shall implement the general ROM format as defined in IEEE 1212:2001 and IEEE 1394. Additional information required for implementations of this standard shall be included in one of the unit directories. Figure 1 shows an example of the configuration ROM implementation for this standard. BS EN 61883-1:2009 10 6
