From IEEE Std 1394 Serial Bus experiences, as well as the telecom industry as a whole, the value of synchronous transfers is greatly increased if time-of-day clocks can also be synchronized.

Most noteable are IEEE 754 Floating Point >> > and IEEE 1394, and other microprocessor standards.

The project will be taken to the 1394 TA board for approval in July. 8:34 Glyn Roberts discussed the closing report for the PC committee (IEEE802.15-03/189r2) 8:38 Karaoguz reported on 802.11g.

We are also looking at a 1394 traffic model (low quality video model).

Task Assignment From the earlier IEEE 802.11 TGe simulation ad hoc group meeting, Philips was assigned the following tasks in the OPNET 802.11 Wireless LAN model enhancement: · Adding PLCP preamble and header · Adding PHY layer delays such as CCA delay and Rx-Tx turnaround time · Modelling IEEE 802.11a PHY · Adding the interface to IEEE 1394 2.

I know that 1394 has another focus but putting a CAT-5 network is somewhat easier than planning a flexible 1394 network (in Europe we don´t have phone nets like in the US).

• AVBTP 61883 presentation time shall be relative to the 802.1AS clock – Adapt 1394 AV/C Function Control Protocol (FCP) for use in 61883 over AVBTP. – Allow for Proprietary encapsulations via different subtype – Allow for other future expansions via different subtypes.

(see 802.1AS assumptions from AVB document)). • 61883 format over AVBTP will support presentation time using AVBTP timestamp field instead of current 61883 SYT field – 1394/61883 to 1722/61883 gateways will have to take care of all SYT to AVBTP timestamp conversions, synchronization, cross timestamps, etc. – Editor’s note: Need to work out SYT field for SPH = 1 packets as timestamps are on a per source packet basis (MPEG packet) instead of in the CIP header. • AVBTP 61883 presentation time shall be relative to the 802.1AS clock • Adapt 1394 AV/C Function Control Protocol (FCP) for use in 61883 over AVBTP. • Proprietary encapsulations allowed via reserved subtype (7F16) • Allow for other future expansions via different subtypes.

I assume these have been handled already, since 1394 uses a 64-bit address space.

. • Technologies such as IEEE 1394, Bluetooth and USB exist today but each has their own encapsulation, protocols, timing control, etc. such that building interworking functions is difficult.

Examples of devices which can be connected include computers, computer peripherals (similar to USB 2.0's 480 Mbps capability), PDA/HPCs, printers, set top boxes, information kiosks, image displays, virtual reality games, DVD players, and camcorders (similar to IEEE 1394's 400 Mbps capability).

It was noted that meshing also needs “hand over”. 11:42 Peter Johansson presented new MAC primitives for Synchronization support for 1394 or any time sync’ed protocol adaptation (document 03-0444-00-0030).

From IEEE Std 1394 Serial Bus experiences, as well as the telecom industry as a whole, the value of synchronous transfers is greatly increased if time-of-day clocks can also be synchronized.

Like the 1394 standards for wireless, this would provide another example of the importance and usefulness of having and following standards that any consumer or engineering manager could point to - which ultimately helps us all.
