Dating in the 19 s be very structured
It appears in the sender, from, to, cc, bcc, and reply-to fields. For use in this format the internet address is divided into eight bit fields and the value of each field is represented in decimal digits. Using again the example above, assume GRAPHICS and VOICE data were to be presented using sequential ordering. A detailed picture transmitted at 9600 baud takes minutes to print.The mailbox is a property list of objects that combine to specify a destination recipient for a message. For example, the ARPANET address of ISIE is 167837748 and is represented as 10,1,0,52. Mailbox This is the destination address of a user of the internetwork mail system. )endlist )endlist Independent Ordering It is apparent that some output devices are very slow in comparison to others. It is inconvenient for the user to wait on such a device when the voice or text information which accompanies it is short.
Structured Text ........................................... MPMs are located in several networks and together constitute an internetwork message delivery system.In particular the body value may be highly structured. The order indicators are SEQUENTIAL, SIMULTANEOUS, and INDEPENDENT. The sender will contain the address of the individual who sent the message. The structure of multimedia messages which use this scheme will be demonstrated by a few simple examples chosen to illustrate a basic text document and the different ordering options.Older message systems have considered the document to be divided into a header and a body, and have used keywords to indicate specific header fields (e.g., date, to, subject). Presentation Element A property list of media structures. Sometimes it will be desired to direct the replies of a message to some address other than the from or the sender. A Structured Format for Transmission of Multi-Media Documents Specification R 450 Block The unit of Rapicom 450 data (585 bits). In some cases this is NOT the same as the author of the message. The last example will suggest some more exotic uses.It is impossible to foresee the many forms documents will take so the standard for a document header must be flexible. )endlist )endlist Simultaneous Ordering This ordering option is used to indicate when separate streams are to be presented in parallel.The approach here is to define a set of basic fields and allow addition of whatever fields are necessary. For example, assume GRAPHICS and VOICE data were to be presented using simultaneously.
