Step 624, transmitting terminal plays out control to receiving terminal.Specifically, due to all being played out between transmitting terminal and receiving terminal to identical multimedia resource, thus transmitting terminal can play out control on the screen interface of itself, such as dragging playing progress rate, pause, F.F., next pictures etc., then transmitting terminal is after control operation is detected, corresponding control information can be sent to receiving terminal, then receiving terminal can be according to the control information received, and execution is corresponding to play control.
Step 625, in transmitting terminal not in the case where playing multimedia resource, due in the absence of corresponding address information, thus the directly screen-picture content of crawl transmitting terminal.
Step 626, the screen-picture content grabbed encode and compression transmission is to receiving terminal, after being decoded for receiving terminal to the data received, obtain the screen-picture content of transmitting terminal.By the step flow of step 601, step 625 and step 626, with reference to other steps flow charts, from regardless of whether whether transmitting terminal currently plays multimedia resource or under other arbitrary interfaces, Screen sharing of the transmitting terminal to receiving terminal can be realized.
Pass through above-mentioned technical proposal, especially in the case where synchronously playing Internet resources, because transmitting terminal only needs to send control information to receiving terminal, the source synchronous that can be achieved therebetween is played and controlled, transmitted data amount is significantly cut down, bandwidth consumption diminishes, it is possible to provide smaller data delay and the poor more preferable adaptability of wireless network environment.
It should be noted that, although not referring to the quantity of control terminal and controlled terminal in the present invention, but actually technical scheme is applied to a variety of situations such as one-to-one, one-to-many, many-one, multi-to-multi, because no matter quantity, for any one control terminal for corresponding controlled terminal, its control process is actually identical.
Technical scheme is described in detail above in association with accompanying drawing, in view of in correlation technique, when the broadcasting for carrying out multimedia resource between the terminals is shared, need directly to be sent data encoding to controlled terminal by control terminal, requirement for control terminal and network environment is higher, therefore, the invention provides control terminal, controlled terminal, resource-sharing method and system, when can make it that carrying out multimedia resource between control terminal and controlled terminal shares, without directly transmitting broadcasting pictures data, section Bandwidth-saving resource, reduces the requirement to control terminal.
