24、e defined in IEC 61834-6, Clause 10 is used. The source packet size for the SDL-DVCR data stream is 240 bytes, divided into 3 DIF blocks. The correspondence between DIF blocks and source packets for the SDL525-60 system and the SDL625-50 system are shown in Figure 1 and Figure 2 respectively. EN 618

25、83-5:2005 4 4.2 Packetization of source packet of the SDL-DVCR data stream A source packet shall not be divided and shall be equal to a data block. Data blocks transmitted in an IEEE 1394 isochronous cycle shall be determined according to the TR value in the CIP header (see 5.2). An empty packet is

26、placed in any cycle with no data block. Where the TR value is 002(1x), one or no data block is transmitted; 012(2x), two or no data block are transmitted; 102(4x), four or no data block are transmitted. The SYT field of the CIP header (see 5.1) is used to synchronize transmitter and receiver. 4.3 Tr

27、ansmission order of video frames for high-speed transmission The transmission order of data within one video frame is defined in Figure 1 and Figure 2. For high-speed transmission, transmission order of each video frame data shall follow the time sequence. 5 CIP header 5.1 CIP header for SDL-DVCR da

28、ta stream The structure of the CIP header for the SDL-DVCR data stream is the same as the structure of the CIP header for the SD-DVCR data stream (see IEC 61883-2, 5.1). The DBS for SDL takes different values from that for SD through the difference of data block size as given in 4.1. 5.2 FDF area Th

29、e STYPE takes different values as shown in Table 1 of IEC 61883-2. Where the STYPE is 000012, TR is defined as follows. TR: 012= 2x 102= 4x 112= Reserved for future definition 5.3 DBC values Increments of DBC value shall be determined according to the TR value. Where the TR value is 002(1x), the DBC

30、 value increments with 1; 012(2x), the DBC value is a multiple of 2; 102(4x), the DBC value is a multiple of 4. EN 61883-5:2005 5 5.4 CIP header for the SDL525-60 system For the SDL525-60 system, the values of the CIP header components are as follows. DBS: 001111002FN: 002QPC: 0002SPH: 0 DBC (see 5.

32、 4x 5.6 Transmission timing The transmitter shall transmit a time stamp value in the SYT field once every video frame period. The time stamp should be transmitted in a packet that meets the following conditions: packet_arrival_time_L time stamp value time stamp value transmission_delay_limit packet_

33、arrival_time_F where packet_arrival_time_F is the cycle time when the first bit of the packet which has the time stamp has arrived at the receiver; packet_arrival_time_L is the cycle time when the last bit of the packet which has the time stamp has arrived at the receiver; transmission_delay_limit =

34、 450 s. In case of Hx (H = 1,2,4) transmission, KH data blocks are transmitted in a video frame period M using K isochronous packets. Isochronous packet n contains H data blocks of nH, nH+1, . and (n+1) H1. EN 61883-5:2005 6 The isochronous packet n of a video frame period M should be transmitted on

35、 the following conditions (n = 0, . , K1): packet_arrival_time_L nominal timing for isochronous packet n nominal timing for isochronous packet n transmission_delay_limit packet_arrival_time_F where packet_arrival_time_F is the cycle time when the first bit of the isochronous packet n has arrived at

36、the receiver; packet_arrival_time_L is the cycle time when the last bit of the isochronous packet n has arrived at the receiver; K is the number of isochronous packets without empty packets in a video frame period. K = 250 (SDL525-60 system) K = 300 (SDL625-50 system) Nominal timing for isochronous

37、packet n = TM + (TM+1 TM) x n/K. TMis the time stamp for video frame period M transmitted in the SYT field.
