The finger URL of mentioning in the above method (Locator) comprises the channel information and the programme information of programme televised live correspondence simultaneously, and following two kinds of manifestation modes are arranged in an embodiment of the present invention:
Mode one: described finger URL is the TV unified resource identifier (tv uri) of expansion.
Here we are referred to as tvuri_locator; It is the parameter that has expanded the example information in the channel of can describing on the basis of conventional t v uri, such as the iptv-param parameter.Described example information can be the information (such as the play start time of direct broadcast band content and play the play start time and the playing duration time of concluding time or direct broadcast band content) of specific programme information (can be program identification) or special time period or the combination of the two.Like this, the tv uri after the expansion not only can describe a channel, can also describe the program of certain interior concrete program of a channel or certain concrete time period broadcast.
tvuri_locator ＝tvuri[iptv-param]
tvuri ＝＂tv:＂[broadcast]
broadcast ＝dns-identifier
dns-identifier ＝*(domainlabel＂.＂)toplabel[＂.＂]
domainlabel＝alphanum|alphanum*(alphanum|＂-＂)alphanum
toplabel ＝alpha|alpha*(alphanum|＂-＂)alphanum
The iptv-param parameter of redetermination is as follows, can carry parameters such as being not limited to mode, contentID, start, duration, end.
iptv-param＝[mode_param][contentID_param][start_param][duration_param][end_param]
mode_param ＝＂mode＝＂mode
mode ＝＂scheduled＂|＂ondemand＂
contentID_param＝＂contentID＝＂string
start_param＝＂start＝＂string refer?to?ISO?8601-2004?20040506T130000+08
duration_param＝＂duration＝＂string refer?to?ISO?8601-2004?P0Y6M5DT3H0M0S
end_param＝＂end＝＂string refer?to?ISO?8601-2004?20040506T130000+08
When tvuri_locator represented in the IPTV system address of certain programme televised live in the direct broadcast band, the implication of each parameter was described as follows among the iptv-param:
[mode_param] is ＂ scheduled ＂, and representing this address is the address of a programme televised live;
[contentID_param] is the sign of above-mentioned programme televised live in its corresponding direct broadcast band;
The zero-time that on behalf of above-mentioned programme televised live, [start_param], [end_param] occur in its corresponding direct broadcast band respectively;
[duration_param] expression time that above-mentioned programme televised live continued.
For example, the program identification such as " hero " is: crid: //zhangyimou.com/hero
Can express above-mentioned programme televised live with the tvuri_locator of following form and appear at position in the direct broadcast band.
1. the broadcast time at central authorities' 6 covers is 2008-08-0808:00:00, two hours film of duration " hero ":
tvuri_locator＝tv:cctv-6.cctv.com；mode＝scheduled；start＝2008-08-08T08:00:00Z；duration＝PT02H00M
tvuri_locator＝tv:cctv-12.cctv.com；mode＝scheduled；contentID＝hero-hd003；start＝2008-08-10T08:00:00Z；end＝2008-08-10T10:00:00Z
The tv uri of above-mentioned expansion is applied in the IPTV system, it is the more specific location information that is used to describe certain programme televised live, this mode not only can be used in the process of live program addressing in the present invention, but also can be applied in other multiple business environment, tv uri such as expansion is applied in PPV (Pay Per View, the per minute sponsored program) in the business, is used for controlling the program of watching specific program or special time period to broadcast.
Mode two: described finger URL adopts channel identication to describe channel information, and this channel identication can adopt tv uri form; Also comprise example information in this finger URL with other form performance.
Above-mentioned example information can include but not limited to: the effective time of the mode of playing programs, the sign of program instance, playing programs; Operations such as these information can and increase by the address resolution device definition, modification are similar to the information in the defined iptv-param parameter in the mode one, and the order of these informations parameter can be random.Example information does not belong to the part in the tv uri form, but belongs to the programme information part of finger URL.Program terminal and playing programs server must can be discerned above-mentioned program description, thereby can the programme information in the finger URL be extracted.
Association between above-mentioned channel identication and the example information can connect by additional character, as symbol " @ ".
For example, the program identification such as " hero " is: crid: //zhangyimou.com/hero
1. program description can be before channel identication in the finger URL, as:
1: one of example is enclosed within the corresponding locator of the program " hero " of on August 1st, 2008 from 4 o'clock to broadcast in 6 o'clock in central authorities six and is
mode＝scheduled；start＝2008-08-01T04:00:00+08；end＝2008-08-1T06:00:00+08＠tv:cctv-6.cctv.com
2: one of examples start broadcasting from 20 of on July 20th, 2008 at central authorities' six covers, and the locator that the program " hero " that continues 1 hour 50 minutes is corresponding is
mode＝scheduled；start＝2008-07-20T20:00:00Z；duration＝PT01H50M＠tv:cctv-6.cctv.com
2. program description also can be arranged on after the channel identication in the finger URL, as:
3: one of examples are enclosed within the corresponding locator of the program " hero " of on August 1st, 2008 from 4 o'clock to broadcast in 6 o'clock in central authorities six and are
tv：cctv-6.cctv.com＠mode＝ondemand；start＝2008-08-01T00:00:00+08；end＝2008-09-30T23：59:59+08
