Embodiment
For making technical scheme of the present invention and advantage clearly understand, below in conjunction with drawings and the specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the schematic flow sheet of the method for carrying out video calling in the embodiment of the present invention.
As shown in Figure 1, the method for carrying out video calling in the embodiment of the present invention comprises step as described below:
Step 101, after video calling is set up, transmitting terminal is monitored the current network bandwidth by the monitoring periods T preset.
In a particular embodiment of the present invention, first need to set up video calling.After video calling is set up, transmitting terminal is just monitored regular the current network bandwidth, namely just once monitors current network bandwidth every a default monitoring periods T, knows current network bandwidth W.Wherein, the length of described default monitoring periods T can pre-set according to practical situations.
Step 102, when the monitored network bandwidth is higher than the threshold value preset, transmitting terminal transmits the video data of high definition code check to receiving terminal, and receiving terminal empties caching record, and the video data that cache-time length is L again also plays the video data received in real time.
Because transmitting terminal can monitor the current network bandwidth to obtain current network bandwidth W in a step 101, therefore in the inventive solutions, transmitting terminal just can judge according to the monitored network bandwidth and default threshold value, judges that whether the network bandwidth of monitoring is higher than predetermined threshold value.When the monitored network bandwidth is higher than the threshold value preset, represent that current network condition is relatively good, the available network bandwidth is higher, is applicable to the video data transmitting high definition code check.Therefore, in this step, transmitting terminal will transmit the video data of high definition code check to receiving terminal.And receiving terminal first can empty original caching record, the video data that buffer memory is new again, the time span of the new video data of this buffer memory is L; Meanwhile, this receiving terminal also will play the video data received in real time.
Step 103, when the monitored network bandwidth is less than or equal to the threshold value preset, transmitting terminal stops transmitting video data to receiving terminal, and the time span of receiving terminal repeat playing buffer memory in a upper monitoring periods is the video data of L.
In a particular embodiment of the present invention, when the monitored network bandwidth is less than or equal to the threshold value preset, represent that current network condition is poor, the available network bandwidth is less, is no longer applicable to the video data transmitting high definition code check.Therefore, in this step, stopping is transmitted video data, to save the network bandwidth by transmitting terminal; Because transmitting terminal now no longer sends video data (but not stopping the transmission of speech data), therefore receiving terminal cannot receive real-time video data again, so the time span of repeat playing buffer memory in a upper monitoring periods is now that the video data of L is with the broadcasting of the video data of alternative real-time reception by receiving terminal.
In addition, in a particular embodiment of the present invention, described L can be less than or equal to default monitoring periods T.Such as, when L equals T, namely the time span of the video data of receiving terminal institute buffer memory and the monitoring periods T-phase etc. of carrying out network bandwidth monitoring is represented, therefore, after receiving terminal plays the video data of institute's buffer memory, transmitting terminal just will again be monitored the network bandwidth and obtain monitoring result, and then determine whether to transmit video data according to monitoring result, and receiving terminal also can determine real time video data or the video data of self institute's buffer memory of playing transmitting terminal transmission thereupon.
Due in the video call process of reality, both call sides is all generally converse in the face of camera, the environment at both call sides place is generally also all static, therefore the change between each consecutive image of gathering of camera is also little, and the video image that the both sides of video calling see is also almost constant.Therefore, in technique scheme of the present invention, when the monitored network bandwidth is lower, receiving terminal can play before the time span of institute's buffer memory be the video data of T, and do not play real-time video data (now, the transmission of speech data remains real-time), now the user of the both sides of video calling still can see dynamic video data, instead of static image information; Although this dynamic video data is not real-time video data, but it is also little with the difference of real-time video data, therefore the both sides carrying out video calling may be difficult to perceive the change of video data, thus can when reducing resource occupying, still for user provides smooth video calling to experience, thus effectively ensure the video calling experience that user is good, but also cost savings taking of Internet resources, improve the utilance of Internet resources.In addition, due in the methods described above, transmitting terminal can take situation according to the network bandwidth, automatically adjust the transmission policy of video data, and carry out manual operations continually without the need to user, therefore greatly reduce the workload of user, improve the Experience Degree of user further.

Step 202, transmitting terminal is monitored the current network bandwidth by default monitoring periods T.
According to monitoring result, step 203, judges that whether the network bandwidth of monitoring is higher than the threshold value preset; If so, then step 204 is performed; Otherwise, perform step 206.
Step 204, transmitting terminal transmits the video data of high definition code check to receiving terminal.
Step 205, receiving terminal empties caching record, and the video data that cache-time length is L again also plays the video data received in real time.Perform step 208.
Step 206, transmitting terminal stops transmitting video data to receiving terminal.
Step 207, the time span of receiving terminal repeat playing buffer memory in a upper monitoring periods is the video data of L.
Step 208, when the playing duration of receiving terminal reaches the duration T of default monitoring periods, returns and performs step 202.
By above-mentioned step 201 ~ 208, transmitting terminal according to the situation that takies of the network bandwidth (namely judging that whether the network bandwidth of monitoring is higher than the threshold value preset), can dynamically adjust the transmission policy of video data.When the occupancy of the network bandwidth higher (being that the monitored network bandwidth is less than or equal to the threshold value preset), when Internet resources cannot meet the transmission requirement of the video data of high definition code check, transmitting terminal can temporarily stop transmitting video data, and receiving terminal can the time span of repeat playing institute's buffer memory in a upper monitoring periods be then the video data of L; And when the occupancy of the network bandwidth declines (being that the monitored network bandwidth is higher than the threshold value preset), transmitting terminal can recover the video data transmitting high definition code check to receiving terminal.And in whole process, the transmission of speech data is also unaffected, therefore, uses above-mentioned method, both ensure that the good video calling of user is experienced, cost savings again taking of Internet resources, improve the utilance of Internet resources.
