“SDP”（Session Description Protocol, Session Description Protocol）It is for conversation informing, session invitation
The purpose of being initialized with the Multimedia session of other forms provides Multimedia session description.In simple terms, fitted using different
When host-host protocol transfer information to receiving terminal.SDP is in IP phone, for building INVITE and 200 OK response messages
Message body, for caller called subscriber's switched-media information, it is some grammer standards of these information definitions, there is certain form.
According to SDP agreement, SDP includes expansible attribute mechanism, represented with a.By extending SDP attribute, Ke Yiding
Make unique function and media.In SDP, attribute should follow form：a=<attribute>:<value>.
" SIP session initiation protocols "（Session Initiation Protocol）It is a kind of signaling protocol, for first
Begin, the voice and video session in management and termination network, be specifically exactly to be used for the one or more that generates, changes and terminate
Session between participant.
" timestamp（timestamp）" refer to that one can represent that a data have existed before some special time
, the complete, data that can verify that, a typically character string, uniquely identify the time at certain a moment, that is, refer to
00 divides 00 second during 01 day 00 Greenwich Mean Time 1970 year 01 month（I.e. 00:00:00 GMT）Rise to total number of seconds this moment.Such as
147367011700 be timestamp.Timestamp can be converted into time format by the method for coded program, in the present embodiment,
The time format is with " YY/MM/DD HH:MM:SS（I.e. certain year, in such a month, and on such a day some time divided certain second）" mode shows.On such as
The time stated after timestamp conversion is 2,016,/09,/12 16:48:37.
GMT（Greenwich Mean Time）, Chinese is Greenwich mean time, is English also referred to as " universal time "
The standard time of state, and the normative reference of world time.The Anglo-Chinese standard time difference is 8 hours, i.e. Britain
Beijing time late 8 hour of the local time than China.In simple terms, once being aware of the GMT, people are just easy to
Extrapolate local zone time now.For example, certain event occurs in AM GMT 9, China is in the Britain east, north
8 hours more early than the GMT of the capital time, it is possible to know that current thing occurs when equivalent to the Beijing time same day 17.Rule
It is 24 time zones to determine global subdivision（East, each 12 time zones in west）, wherein Greenwich mean time is middle time zone（Zero zone）, eastern 1-12
Area, Xi1-12Qu, adjacent time zone differ one hour, and the earth is rotation from West to East, first sees the sun than west in the east, east
Time is also more early than west, therefore time zone difference east is just, and west be negative, such as 8th area of GMT+8 expressions east, GMT-8 be expressed as western eight
Area.According to formula " local zone time=GMT+time zone is poor ", above-mentioned example GMT=Beijing time -0800=0900+0000 is namely
When Beijing time is 17.
UTC（Universal Time Coordinated, Coordinated Universal Time(UTC)）It is world's unified time, Greenwich mean time
Between, the international coordination time, same concept is almost with GMT.
