It describes the general packet format, data flow management a

36、nd 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 data and control commands which provides for the interconnection of digital audio and video equipment, using

43、rformance 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 AV devic

44、e 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. 4.3 Tran

45、saction 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 be assig

46、ned 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 which tran

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 activation of a new cycle
