It is illustrated below by scheme of multiple embodiments to the application.
Embodiment one
Fig. 3 is the network frame schematic diagram of DVB-RCS system.Wherein, carry out broadcast streaming media service in DVB-RCS system
When, broadcast data is sent to satellite ground transmitting main website from media server, and satellite ground emits main website using broadcast packet by defending
Starry sky mouth sends data, and multiple satellite ground receivers receive identical broadcast data, are sent on subscriber terminal equipment, uses
Family may be viewed by related-program.
It should be noted that the main website of the present embodiment can refer to transmitting terminal (such as above-mentioned satellite ground hair of broadcast data
Penetrate main website), end station can refer to the receiving end (such as above-mentioned satellite ground receiver) of broadcast data.
In the present embodiment, broadcast data is sent to main website from media server, but as long as main website does not receive the wide of end station
It broadcasts solicitation message, just is not eating dishes without rice or wine to send related-program data (eating dishes without rice or wine at this time can be by other data application use).
It is illustrated by taking two end station as an example referring to Fig. 4.When the user of end station 1 needs to watch program, end station 1 is fixed
When send broadcast solicitation message to main website (be assumed to be 30 seconds send once, the format for broadcasting solicitation message is as shown in Table 1), extensively
It broadcasts solicitation message and carries the forward direction signal-to-noise ratio of programme information and the reception downlink signal of end station 1 that 1 user of end station to be watched (assuming that end
It stands and 1 eats dishes without rice or wine to can receive 8PSK (8Phase Shift Keying, 8 phase-shift keyings) signal)；The user of end station 2 needs to watch section
When mesh, end station 2 regularly sends broadcast solicitation message and (is assumed to be 30 seconds and sends once, the format for broadcasting solicitation message can to main website
With as shown in Table 1), broadcast solicitation message carries the programme information that 2 user of end station to be watched and end station 2 receives downlink signal
Forward direction signal-to-noise ratio is (assuming that end station 2 eats dishes without rice or wine to can receive 16APSK (16-ary Amplitude and Phase Shift
Keying, 16 rank Amplitude phase shift keyings) signal).Wherein, the programme information phase that the programme information and end station 2 that end station 1 is applied are applied
Together.After main website receives the broadcast solicitation message of two end station (end station 1 and end station 2), according to the programme information of two end station applications
It determines the broadcast data of forwarding, and the signal-to-noise ratio of comprehensive two end station, sends broadcast data using 8PSK.
In the present embodiment, end station 1 and end station 2 regularly send broadcast solicitation message to main website, if the user of end station 1 stops
Program is only watched, end station 1 stops sending broadcast solicitation message, and main website only receives in setting duration (for example, can be 60 seconds)
To the broadcast solicitation message of end station 2, then it is assumed that only end station 2 is receiving program, therefore switchs to send using 16APSK signal and save
Mesh information.
In the present embodiment, end station 1 and end station 2 regularly send broadcast solicitation message to main website, when end station 1 and end station 2
After user does not watch program, stop sending broadcast solicitation message to main website.If main website is in setting duration (for example, can be 60
Second) in do not receive the broadcast solicitation message of end station 1 and end station 2, can be with it may be considered that receiving broadcast data without end station
Stop sending broadcast data.
Table one

The signal-tonoise information stood determines the modulation format of downlink data.
In the present embodiment, end station does not use the mode for regularly sending broadcast solicitation message, but super in signal-to-noise ratio variation
It crosses and just re-emits broadcast solicitation message after setting threshold value, so that multi-user be avoided to issue a large amount of reversed information.Main website
After receiving the broadcast solicitation message of end station, summarize the signal-tonoise information of all end station, then determines the modulation lattice of downlink data
Formula.
In the present embodiment, after end station user stops viewing program, end station clearly issues a broadcast and stops message, main
Station receives the broadcast that end station is sent and stops message, is carried out summarizing meter according to the signal-tonoise information of the end station of currently viewing program again
It calculates, determines the new modulation format of downlink data.
Embodiment three
The network architecture frame and embodiment one of the present embodiment are consistent.
In the present embodiment, when end station user needs to watch program, end station sends broadcast solicitation message to main website, wherein wrapping
Signal-tonoise information containing end station, the format for broadcasting solicitation message are referred to shown in table one.Main website is according to all end station collected
Signal-tonoise information determine downlink data modulation format.
In the present embodiment, end station opens a random duration timer after signal-to-noise ratio variation is more than setting threshold value,
After the timer expiry, new broadcast solicitation message is just sent to main website, thus avoid influencing a large amount of end station when some variation,
Make a large amount of end station and meanwhile send broadcast solicitation message cause system overload.Main website converges after receiving the broadcast solicitation message of end station
The signal-tonoise information of total all end station, then determines the modulation format of downlink data.
In the present embodiment, after end station user stops viewing program, end station clearly issues a stopping message, and main website is received
The broadcast sent to end station stops message, is carried out summarizing calculating according to the signal-tonoise information of the end station of currently viewing program again,
Determine the new modulation format of downlink data.
