Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear Chu, it is fully described by.
The embodiment of the present invention provides a kind of video call method, and the video call method is applied to terminal device, The terminal device can be mobile phone, panel computer or PC etc., the embodiment of the present invention is not done to this Limit.As shown in figure 1, methods described includes：
Step 101, the Mean Speed according to opposite equip. institute access network, obtain point of the first video information Resolution and frame per second, the video information that first video information collects for camera.
The opposite equip. is described to carry out the terminal device of the other end of video calling with terminal device Opposite equip. can be mobile phone, panel computer or PC etc., the embodiment of the present invention is not limited this.
Example, for the ease of description, terminal device is referred to as local device in the embodiment of the present invention.With During family carries out video calling using local device with opposite equip., local device is gathered by camera The real-time pictures of user, and the real-time pictures are sent to opposite equip., the real-time pictures are first Video information, opposite equip. is receiving the first video information, and first video information is decoded simultaneously It has been shown that, so, using the user of opposite equip. be can watch using local device user it is real-time Picture.But the camera of generally local device is to carry out picture collection according to the highest resolution supported, The resolution ratio and frame per second of the raw frames collected are higher, if the raw frames directly are sent into opposite end Equipment, can cause local device be sent to the first video information of opposite equip. packet it is more, per number Also larger according to wrapping, if the bandwidth for the network that opposite equip. is accessed is smaller, speed is relatively low, then is easily caused The the first video information interim card or the nonsynchronous situation of audio frequency and video shown on opposite equip..If in order to avoid upper Situation is stated, directly the first video information is encoded from relatively low resolution ratio and frame per second, not accounted for The situation of opposite equip. institute access network, then when opposite equip. institute access network situation can be caused preferable, i.e., pair In the case that end equipment originally can receive the video information of high-resolution, first shown on opposite equip. regards The resolution ratio of frequency information is still very low so that of low quality, the influence Consumer's Experience of two-party video call.Cause This, according to the Mean Speed of opposite equip. institute access network, can obtain the first video information resolution ratio and Frame per second.For example, when the Mean Speed of opposite equip. institute access network is higher, larger resolution can be selected Rate and frame per second；When the Mean Speed of opposite equip. institute access network is relatively low, less resolution ratio and frame are selected Rate.
If the time that opposite equip. and local device carry out video calling is also compared short, opposite equip. is to local terminal The Mean Speed that equipment is sent numerical value preset when being dispatched from the factory for opposite equip., the net that this numerical value is used according to user Network type, including LAN (Local Area Network, LAN) access, dial-up access etc., Yi Jiyong Network bandwidth that family is opened etc. is determined.After video calling continues certain time length at that time, opposite equip. can be by Network Mean Speed in the duration is sent to local device.
Step 102, resolution ratio and frame per second according to first video information, to first video information Encoded.
The Mean Speed of institute's access network according to opposite equip. get the first video information resolution ratio and After frame per second, the first video information is encoded according to the resolution ratio and frame per second, opposite end is then sent to and sets It is standby.By forethought has arrived the concrete condition of opposite equip. institute access network, so opposite equip. is shown The first video information shown is not in interim card or the nonsynchronous situation of audio frequency and video, and can also be with compared with high score Resolution is shown.
So, resolution ratio and frame per second when being encoded due to the first video information are according to opposite equip. What the Mean Speed of institute's access network was determined, therefore when the Mean Speed of opposite equip. institute access network is higher, Resolution ratio and frame per second during the first video information coding can be with larger so that preferable in opposite equip. network condition When, more visible picture can be shown, the audio-visual quality of video calling is improved, and then improve user's body Test.
Further, in the Mean Speed according to opposite equip. institute access network, the first video information is obtained Before resolution ratio and frame per second, the negotiation information of opposite equip. transmission, the negotiation information can also be received first Include the Mean Speed of opposite equip. institute access network.
Example, when local device and opposite equip. set up video calling, opposite equip. can be first to this End equipment sends negotiation information, and the negotiation information includes the Mean Speed of opposite equip. institute access network, , can be according to the opposite equip. institute access network in order to which local device is after the first video information is collected Mean Speed, obtains the resolution ratio and frame per second of the first video information.
Preferably, in order to which local device can be according to the network condition of opposite equip., the first video of adjustment in time The resolution ratio and frame per second of information, opposite equip. can periodically send negotiation information.Local device is each After receiving negotiation information, being averaged for current opposite equip. institute's access network for being carried in negotiation information is obtained Speed, then according to the Mean Speed of current opposite equip. institute access network, obtains point of the first video information Resolution and frame per second.Example, the cycle that negotiation information is sent can be 10 minutes, and the opposite equip. is connect The Mean Speed for entering network is the Mean Speed of opposite equip. institute access network in the correspondence cycle.Practical application In, the cycle that negotiation information is sent can be configured as the case may be, and the embodiment of the present invention is not done to this Limit.
In practical application, local device can also set terminal models storage/processing module, existing for storing The relevant information such as model, disposal ability, camera acquisition resolution, the screen size of main flow terminal equipment, When local device and opposite equip. carry out video calling, terminal models are inquired about according to the model of opposite equip. and deposited Storage/processing module, you can obtain the screen size of opposite equip..In practical application, the terminal models storage The model of the existing main flow terminal equipment stored in/processing module, disposal ability, camera acquisition resolution, The relevant informations such as screen size can be increased, changed and be deleted.
Optionally, the negotiation information includes the screen size of opposite equip..Further, according to opposite end , can be with after the Mean Speed of equipment institute access network, the resolution ratio and frame per second that obtain the first video information The resolution ratio and frame per second of first video information are adjusted according to the screen size of opposite equip., obtained Resolution ratio and frame per second after adjustment after the adjustment of first video information, then according to the tune of first video information Frame per second after whole rear resolution ratio and adjustment, is encoded to first video information.
Example, because the species of opposite equip. is more, screen in every kind of equipment it is in different size, it is right For same video information, if shown on less screen, possible display effect is good, but If being shown on giant-screen, it may appear that the relatively low situation of resolution ratio.Therefore enter in local device with opposite equip. During row video calling, opposite equip., which is sent in the negotiation information of local device, can include the screen of opposite equip. Curtain size so that local device can be according to the screen size of opposite equip., point of the first video information of adjustment Resolution and frame per second, in the case where the screen of opposite equip. is larger, make the resolution ratio of the first video information as far as possible It is larger with frame per second, in the case of the screen of opposite equip. is less, less resolution ratio and frame per second can be selected, Alleviate communication pressure.
Further, in the Mean Speed according to opposite equip. institute access network, the first video information is obtained After resolution ratio and frame per second, it can also determine whether the Mean Speed of institute's access network is less than or equal to the first One average threshold, when the Mean Speed of institute's access network is less than or equal to first average threshold, according to The Mean Speed of institute's access network is adjusted to the resolution ratio and frame per second of first video information, obtains Resolution ratio and frame per second after adjustment after the adjustment of one video information, then according to the adjustment of first video information Resolution ratio and frame per second after adjustment, are encoded to first video information afterwards.
Example, all right, but the net that local device is accessed of the network accessed when opposite equip. When the situation of network is poor, if the Mean Speed of the network only accessed according to opposite equip. determines the first video The resolution ratio and frame per second of information, can cause local device send the first video information speed it is slower, opposite end is set It is standby quickly to receive the first video information, still result in the picture card that opposite equip. is shown Or audio frequency and video it is asynchronous situations such as.Therefore, in practical application, in the network accessed according to opposite equip. Mean Speed get the resolution ratio and frame per second of the first video information after, can also first determine whether that local terminal is set Whether the Mean Speed of standby institute access network is less than or equal to the first average threshold, if local device is accessed The Mean Speed of network is more than the first average threshold, illustrates that the speed of local device institute access network is good, can It is adjusted with the resolution ratio and frame per second not to the first video information, if local device institute access network is flat Equal speed is less than or equal to the first average threshold, the speed for illustrating local device institute access network it is poor, it is necessary to According to the Mean Speed of local device institute access network, resolution ratio and frame per second to the first video information are adjusted It is whole, then according still further to frame per second after resolution ratio after adjustment and adjustment, first video information is encoded. For example, when the Mean Speed of local device institute access network is smaller, can suitably reduce the first video information Resolution ratio and frame per second.Wherein, first average threshold is set as the case may be in practical application, It can also be adjusted at any time according to the different situations of network, the embodiment of the present invention is not limited this.
Further, in the Mean Speed according to opposite equip. institute access network, the first video information is obtained After resolution ratio and frame per second, the Mean Speed of institute's access network and the difference of real time rate can also be determined first Whether the first difference threshold is more than or equal to, when the Mean Speed of institute's access network and the difference of real time rate are big When the first difference threshold, according to the Mean Speed of institute's access network and the difference of real time rate to institute The resolution ratio and frame per second for stating the first video information are adjusted, and obtain resolution ratio after the adjustment of the first video information With frame per second after adjustment, then according to resolution ratio after the adjustment of first video information and adjustment after frame per second, it is right First video information is encoded.
Example, the real-time change during situation of network, even if the Mean Speed of local device institute access network Preferably, but if there is others interference, it still may result in local device and send the first video information When network real time rate reduce suddenly, if now local device only accounts for the average speed of institute's access network Rate, without worry network real time rate when, may cause local device send the first video information speed Degree is slower, it is difficult to meet the display demand of opposite equip..And hence it is also possible to according to local device institute access network Whether the Mean Speed of network and the difference of real time rate determine the need for pair more than or equal to the first difference threshold The resolution ratio and frame per second of first video information are adjusted.If the Mean Speed of local device institute access network It is more than or equal to the first difference threshold with the difference of real time rate, illustrates the real-time of local device institute access network The difference of speed and Mean Speed is larger, current out of condition of possible local device institute access network, it is necessary to According to the size of the difference, resolution ratio and frame per second to the first video information are adjusted；If local terminal is set The Mean Speed of standby institute access network and the difference of real time rate are less than the first difference threshold, illustrate local device The real time rate of institute's access network and the difference of Mean Speed are smaller, resolution that can not be to the first video information Rate and frame per second are adjusted.Specifically, when the real time rate and Mean Speed of local device institute access network When difference is larger, the appropriate resolution ratio and frame per second for reducing the first video information.Wherein, the first difference threshold Value is set as the case may be in practical application, can also be adjusted at any time according to the different situations of network Whole, the embodiment of the present invention is not limited this.
Optionally, the negotiation information also includes the real time rate of opposite equip. institute access network.Further, In the Mean Speed according to opposite equip. institute access network, obtain the first video information resolution ratio and frame per second it Afterwards, it can also determine whether the real time rate of opposite equip. institute access network is real-time less than or equal to first first Threshold value, when the real time rate of opposite equip. institute access network is less than or equal to the first real time threshold, according to institute The real time rate for stating opposite equip. institute access network is adjusted to the resolution ratio and frame per second of first video information It is whole, resolution ratio and frame per second after adjustment after the adjustment of the first video information are obtained, then according to first video Resolution ratio and frame per second after adjustment, are encoded to first video information after the adjustment of information.
Example, the network condition that opposite equip. is accessed is also real-time change, although according to opposite equip. The Mean Speed of the network accessed, obtains the resolution ratio and frame per second of the first video information, but if right The network that end equipment is accessed is interfered, and causes if implementing speed reduction, also results in opposite equip. and connect The speed for receiving the first video information is slower so that interim card occurs in the picture that opposite equip. is shown or audio frequency and video are different Situations such as step.Therefore, in practical application, the real time rate for the network that can be accessed according to opposite equip. is true It is fixed whether to need to be adjusted the resolution ratio and frame per second of the first video information.What if opposite equip. was accessed The real time rate of network is less than or equal to the first real time threshold, illustrates the real-time of the network that opposite equip. is accessed Speed is smaller, it is necessary to which resolution ratio and frame per second to the first video information are adjusted, you can reduce the with appropriate The resolution ratio and frame per second of one video information；If the real time rate for the network that opposite equip. is accessed is more than first Real time threshold, illustrates that the real time rate for the network that opposite equip. is accessed is larger, and the first video can not be believed The resolution ratio and frame per second of breath are adjusted.Wherein, first real time threshold is according to specific in practical application Situation set, can also be adjusted at any time according to the different situations of network, the embodiment of the present invention to this not Limit.
Specifically, opposite equip. periodically can be sent in negotiation information, the negotiation information to local device Mean Speed and real time rate including opposite equip. institute access network, the Mean Speed can be correspondence weeks Network Mean Speed in phase, the real time rate can be that network current when sending negotiation information is fast in real time Rate.In practical application, real time rate can also be sent by other information, and the cycle for sending real time rate can With smaller, in order to which local device is in time according to the real time rate of opposite equip. institute access network, regarded to first The resolution ratio and frame per second of frequency information are adjusted.
Example, can also include the decoding capability of opposite equip. in the negotiation information, local device according to The decoding capability of opposite equip. determines the need for being adjusted the resolution ratio and frame per second of the first video information. If the decoding capability of opposite equip. is stronger, the video information of high-resolution can be decoded, then can be appropriate Increase the resolution ratio and frame per second of the first video information；If the decoding capability of opposite equip. is weaker, decoding is only capable of The video information of low resolution, then can suitably reduce the resolution ratio and frame per second of the first video information.
Optionally, local device can also receive the second video information of opposite equip. transmission, then obtain institute The resolution ratio and frame per second of the second video information are stated, and according to the resolution ratio and frame per second of second video information, Show second video information.
Example, when local device and opposite equip. progress video calling, local device should take the photograph this section As the real-time pictures for the user that head is collected are sent to opposite equip., also to receive the second of opposite equip. transmission Video information, second video information has reacted the real-time pictures of the user using opposite equip..Local terminal is set For after the second video information that opposite equip. is sent is received, the second video information is decoded, then Obtain the resolution ratio and frame per second of the second video information, the resolution ratio and frame per second of second video information are pair Resolution ratio and frame per second when end equipment is encoded to the second video information, then local device is according to the resolution Rate and frame per second show the second video information, you can set so that being watched using the user of local device using opposite end The real-time pictures of standby user.
Further, can also be true first after the resolution ratio and frame per second of second video information is obtained Whether the Mean Speed of fixed accessed network is less than or equal to the second average threshold, when the network accessed When Mean Speed is less than or equal to second average threshold, according to the Mean Speed of the network accessed to institute The resolution ratio and frame per second for stating the second video information are adjusted, and obtain resolution ratio after the adjustment of the second video information With frame per second after adjustment, then according to frame per second after resolution ratio after the adjustment of second video information and adjustment, show Show second video information.
Example, if the Mean Speed of local device institute access network is smaller, and what local device was got Resolution ratio and frame per second when opposite equip. is encoded to the second video information is larger, may cause local device It can not continuously receive the second video information, therefore can also be according to the average speed of local device institute access network The resolution ratio and frame per second that rate determines the need for during to the second video information are adjusted.Specifically, local terminal is set Whether the standby Mean Speed for determining accessed network is less than or equal to the second average threshold, if local device Determine whether the Mean Speed of accessed network is less than or equal to the second average threshold, illustrate that local device is true The Mean Speed of fixed accessed network is smaller, may result in local device and can not continuously receive second and regards Frequency information, therefore the Mean Speed of accessed network can be determined to the second video information according to local device When resolution ratio and frame per second be adjusted, for example, resolution ratio when can suitably reduce the second video information and Frame per second；If local device determines whether the Mean Speed of accessed network is more than the second average threshold, say Bright local device determines that the Mean Speed of accessed network is larger, does not interfere with local device to the second video The reception of information, resolution ratio and frame per second when can not be to the second video information be adjusted.Wherein, it is described Second average threshold is set as the case may be in practical application, can also according to the different situations of network It is adjusted at any time, the embodiment of the present invention is not limited this.
Further, can also be true first after the resolution ratio and frame per second of second video information is obtained Whether the Mean Speed of fixed accessed network and the difference of real time rate are more than or equal to the second difference threshold, When the Mean Speed of the network accessed and the difference of real time rate are more than or equal to second difference threshold, According to the resolution ratio of the Mean Speed of the network accessed and the difference of real time rate to second video information It is adjusted with frame per second, obtains resolution ratio and frame per second after adjustment after the adjustment of the second video information, then basis Resolution ratio and frame per second after adjustment, show second video information after the adjustment of second video information.
Example, the situation of the network accessed by local device is real-time change, if local device During receiving the second video information, the real time rate of network deteriorates suddenly, it is also possible to cause local device The second video information can not continuously be received.Therefore in practical application, local device institute can also be determined first Whether the Mean Speed of the network of access and the difference of real time rate are more than or equal to the second difference threshold, if The Mean Speed of local device institute access network and the difference of real time rate are more than or equal to the second difference threshold, Illustrate that the real time rate of local device is changed greatly, local device may be influenceed to connect the second video information Receive, it is necessary to be carried out according to Mean Speed and the difference of real time rate to the resolution ratio and frame per second of the second video information Adjustment, for example, can suitably reduce the resolution ratio and frame per second of the second video information；If local device is connect Enter the Mean Speed of network and the difference of real time rate is less than the second difference threshold, illustrate the real-time of local device Speed change is smaller, may not influence reception of the local device to the second video information, it is not necessary to second The resolution ratio and frame per second of video information are adjusted.Wherein, second difference threshold is root in practical application Set, can also be adjusted at any time according to the different situations of network, the embodiment of the present invention according to concrete condition This is not limited.
The embodiments of the invention provide a kind of video call method, methods described includes：According to opposite equip. institute The Mean Speed of access network, obtains the resolution ratio and frame per second of the first video information, first video information The video information collected for camera；According to the resolution ratio and frame per second of first video information, to described First video information is encoded.Compared to prior art, point when being encoded due to the first video information Resolution and frame per second are determined according to the Mean Speed of opposite equip. institute access network, therefore when opposite equip. institute When the Mean Speed of access network is higher, resolution ratio and frame per second during the first video information coding can with larger, So that when opposite equip. network condition is preferable, more visible picture can be shown, video calling is improved Audio-visual quality, and then improve Consumer's Experience.
The embodiment of the present invention provides a kind of video call method, is said by taking first terminal and second terminal as an example It is bright, wherein, first terminal and second terminal can be mobile phone, panel computer, personal telegram or set top box Deng the embodiment of the present invention is not limited this.The video call method as shown in Fig. 2 including：
Step 301, first terminal receive the negotiation information that second terminal is sent, and the negotiation information includes the The Mean Speed of two terminal institute access networks, real time rate and/or screen size, perform step 302.
When first terminal and second terminal set up video calling, second terminal can be sent out to first terminal first Negotiation information is sent, the negotiation information includes the Mean Speed of second terminal institute access network, real time rate With the screen size of second terminal, in order to local device can according to above-mentioned parameter in time to being sent to second First video information of terminal is adjusted.
Step 302, the camera of first terminal carry out the first video information collection, perform step 303.
The camera of first terminal is when carrying out the collection of the first video information, it will usually according to the highest supported Resolution ratio and frame per second are acquired.Conventional camera supports regarding for the resolution ratio such as 480P, 720P, 1080P The collection of frequency information.
Step 303, first terminal obtain the first video according to the Mean Speed of second terminal institute access network The resolution ratio and frame per second of information, perform step 304.
Example, if the Mean Speed of second terminal institute access network is larger, illustrate that second terminal can be compared with The big packet of fast reception, therefore higher resolution ratio and frame per second can be selected, if second terminal is connect The Mean Speed for entering network is smaller, illustrates the situation of second terminal institute access network and may influence to regard to first The reception of frequency information, therefore relatively low resolution ratio and frame per second can be selected.
Step 304, first terminal according to the screen size of second terminal to the resolution ratio of the video information and Frame per second carries out first time adjustment, performs step 305.
Example,, may display effect if shown on less screen for same video information Fruit is good, but if being shown on larger screen, it may appear that the relatively low situation of resolution ratio.Therefore first Terminal according to the screen size of second terminal, can adjust the resolution ratio and frame per second of the first video information.For example, In the case where the screen of second terminal is larger, the resolution ratio and frame per second of the first video information of appropriate increase, In the case of the screen of second terminal is less, it can suitably reduce the resolution ratio and frame per second of the first video information, Alleviate communication pressure.The size of conventional screen is 4 inches or 3.5 inches.
Step 305, first terminal determine whether the Mean Speed of institute's access network is less than or equal to first and is averaged Threshold value；When the Mean Speed of first terminal institute access network is less than or equal to the first average threshold, step is performed Rapid 306；When the Mean Speed of first terminal institute access network is more than first average threshold, step is performed Rapid 311.
Example, by the size of the Mean Speed of first terminal institute access network, the first video can be influenceed to believe The transmission speed of breath, therefore first terminal is before the first video information is sent, in addition it is also necessary to determine to be connect first Whether the Mean Speed for entering network is less than or equal to the first average threshold.If first terminal institute access network Mean Speed is more than the first average threshold, illustrates that the speed of first terminal institute access network is good, can not be right The resolution ratio and frame per second of first video information are adjusted, if the Mean Speed of first terminal institute access network Less than or equal to the first average threshold, illustrate that the speed of first terminal institute access network is poor, it is necessary to first The resolution ratio and frame per second of video information are adjusted.
Step 306, first terminal are according to the resolution ratio of the Mean Speed of institute's access network to the video information Second is carried out with frame per second to adjust, and performs step 307.
Example, if the Mean Speed of first terminal institute access network is less than or equal to the first average threshold, Illustrate that the Mean Speed of first terminal institute access network is smaller, first terminal may be influenceed to believe the first video The transmission of breath, therefore can suitably reduce the resolution ratio and frame per second of the first video information；If first terminal institute The Mean Speed of access network is more than the first average threshold, illustrates the Mean Speed of first terminal institute access network It is larger, transmission of the first terminal to the first video information is not interfered with, therefore can not be to the first video information Resolution ratio and frame per second be adjusted.
Step 307, first terminal determine institute's access network Mean Speed and real time rate difference it is whether big In or equal to the first difference threshold；When the Mean Speed and the difference of real time rate of first terminal institute access network During more than or equal to the first difference threshold, step 308 is performed；When the average speed of first terminal institute access network When rate and the difference of real time rate are less than the first difference threshold, step 311 is performed.
Example, what it is by first terminal institute access network is real-time change, and first terminal institute access network The real time rate of network can also influence transmission of the first terminal to the first video information, therefore can also determine first Whether the Mean Speed of first terminal institute access network and the difference of real time rate are more than or equal to the first difference threshold Value.If the difference is more than or equal to the first difference threshold, illustrate the real-time speed of first terminal institute access network Rate and Mean Speed difference are larger, and the real time rate of network may receive interference and reduce, therefore can influence the The transmission of one the first video information of terminal-pair is, it is necessary to which resolution ratio and frame per second to the first video information are adjusted； If the difference is less than the first difference threshold, illustrate the real time rate and average speed of first terminal institute access network Rate difference is smaller, does not interfere with transmission of the first terminal to the first video information, therefore need not be regarded to first The resolution ratio and frame per second of frequency information are adjusted.
Step 308, first terminal are according to the Mean Speed of institute's access network and the difference of real time rate to described The resolution ratio and frame per second of video information carry out third time adjustment, perform step 309.
Example, if the Mean Speed of first terminal institute access network and the difference of real time rate are more than or waited In the first difference threshold, illustrate that the real time rate of first terminal institute access network is changed greatly, may influence Transmission of the first terminal to the first video information, thus can suitably reduce the first video information resolution ratio and Frame per second；If the Mean Speed of first terminal institute access network and the difference of real time rate are less than the first difference threshold Value, illustrates that the real time rate change of network is little, does not interfere with transmission of the first terminal to the first video information, Therefore the resolution ratio and frame per second of the first video information can not be adjusted.
Step 309, first terminal determine whether the real time rate of second terminal institute access network is less than or equal to First real time threshold；When the real time rate of second terminal institute access network is less than or equal to the first real time threshold, Perform step 310；When the real time rate of second terminal institute access network is more than the first real time threshold, perform Step 311.
Example, the real time rate of second terminal institute access network can influence second terminal to the first video information Reception, therefore be also required to be determined whether to the first video according to the real time rate of second terminal institute access network The resolution ratio and frame per second of information are adjusted.If the real time rate for the network that second terminal is accessed be less than or Equal to the first real time threshold, illustrate that the real time rate for the network that second terminal is accessed is smaller, may influence Second terminal is to the reception of the first video information, it is necessary to which resolution ratio and frame per second to the first video information are adjusted It is whole；If the real time rate for the network that second terminal is accessed is more than the first real time threshold, illustrate second terminal The real time rate of the network accessed is larger, reception of the second terminal to the first video information is not influenceed, therefore The resolution ratio and frame per second of first video information can not be adjusted.
Step 310, first terminal are according to the real time rate of second terminal institute access network to the video information Resolution ratio and frame per second carry out the 4th time adjustment, perform step 311.
Example, if the real time rate for the network that second terminal is accessed is less than or equal to the first real time threshold, The resolution ratio and frame per second of the first video information can suitably be reduced；If the network that second terminal is accessed is real-time Speed is more than the first real time threshold, then the resolution ratio and frame per second of the first video information need not be adjusted.
Step 311, first terminal enter according to the resolution ratio and frame per second finally determined to first video information Row coding, performs step 312.
Example, first terminal is carried out according to above-mentioned parameters to the resolution ratio and frame per second of the first video information Multiple adjustment, the resolution ratio and frame per second obtained after then being adjusted according to last time is entered to the video information Row coding.
The first video information after coding is sent to second terminal by step 312, first terminal, performs step 313。
After first terminal is encoded to the first video information, first video information is the net for meeting two ends Network situation, meets the screen display demand of second terminal, therefore more can quickly be sent to second eventually again End.
Step 313, second terminal are decoded to the first video information received, obtain first video The resolution ratio and frame per second of information, perform step 314.
Example, when second terminal is that first terminal sets up dialogue, understand the by interaction protocol The coded system of one terminal, therefore after the video information that second terminal is received, first can be regarded to this Frequency information is decoded, and obtains the resolution ratio and frame per second of first video information.Conventional coding/decoding capability Can be for H.264.
Step 314, second terminal determine whether the Mean Speed of institute's access network is less than or equal to second and is averaged Threshold value；When the Mean Speed of second terminal institute access network is less than or equal to the second average threshold, step is performed Rapid 315；When the Mean Speed of second terminal institute access network is more than the second average threshold, step 318 is performed.
Example, if the Mean Speed of second terminal institute access network is smaller, second terminal may be influenceed Reception to the first video information, thus second terminal can according to the Mean Speed of institute's access network determine be It is no to need to be adjusted the resolution ratio and frame per second of the first video information.If second terminal institute access network Mean Speed is less than or equal to the second average threshold, illustrates that the Mean Speed of second terminal institute access network is smaller, Second terminal may be influenceed to the reception of the first video information, it is necessary to the resolution ratio of the first video information and Frame per second is adjusted；If the Mean Speed of second terminal institute access network is more than the second average threshold, explanation The Mean Speed of second terminal institute access network is larger, does not interfere with second terminal and the first video information is connect Receive, therefore the resolution ratio and frame per second of the first video information can not be adjusted.
Step 315, second terminal are according to the Mean Speed of institute's access network to point of the video information received Resolution and frame per second carry out first time adjustment, perform step 316.
Example, when the Mean Speed of second terminal institute access network is less than or equal to the second average threshold, The resolution ratio and frame per second of the first video information can suitably be reduced, in order to which second terminal can be quickly continuous Receive the first video information；When the Mean Speed of second terminal institute access network is more than the second average threshold, The resolution ratio and frame per second of first video information can not be adjusted.
Step 316, second terminal determine institute's access network real time rate and Mean Speed difference it is whether big In or equal to the second difference threshold；When the real time rate and the difference of Mean Speed of second terminal institute access network More than or equal to the second difference threshold, step 317 is performed；When the real time rate of second terminal institute access network It is less than the second difference threshold with the difference of Mean Speed, performs step 318.
Example, second terminal institute access network is also real-time change, if receiving first in second terminal During video information, second terminal institute access network, which receives certain interference, causes real time rate to reduce, can Reception of the second terminal to the first video information can be influenceed, therefore second terminal can be according to institute's access network Real time rate and the difference of Mean Speed determine the need for entering the resolution ratio and frame per second of the first video information Row adjustment.If the real time rate of second terminal institute access network and the difference of Mean Speed are more than or equal to the Two difference thresholds, illustrate that the real time rate of second terminal institute access network is changed greatly, may influence second The reception of the video information of terminal-pair first is, it is necessary to which resolution ratio and frame per second to the first video information are adjusted； If the real time rate of second terminal institute access network and the difference of Mean Speed are less than the second difference threshold, say The real time rate change of bright second terminal institute access network is little, does not interfere with second terminal and the first video is believed The reception of breath, therefore the resolution ratio and frame per second of the first video information can not be adjusted.
Step 317, second terminal are according to the real time rate of institute's access network and the difference of Mean Speed to receiving The resolution ratio and frame per second of the video information arrived carry out second and adjusted, and perform step 318.
Example, when the real time rate of second terminal institute access network and the difference of Mean Speed are more than or equal to During the second difference threshold, it can suitably reduce the resolution ratio and frame per second of the first video information, be easy to second terminal The first video information of quick continuous reception；When the real time rate and Mean Speed of second terminal institute access network Difference be less than the second difference threshold when, the resolution ratio and frame per second of the first video information can not be adjusted.
Step 318, second terminal are regarded according to being shown the resolution ratio and frame per second of the video information finally determined Frequency information.
After second terminal is adjusted according to above-mentioned parameters to the resolution ratio and frame per second of the first video information, Be not in interim card or sound during so that second terminal showing the first video information according to final resolution ratio and frame per second Situations such as video is asynchronous, and in the case where meeting network demand, the first video of display is improved as far as possible Resolution ratio and frame per second during information, complete the dynamic adjustment to the first video information resolution ratio and frame per second.
It should be noted that the sequencing of the step of video call method provided in an embodiment of the present invention can be with Suitably adjusted, step according to circumstances can also accordingly be increased and decreased, any skill for being familiar with the art Art personnel the invention discloses technical scope in, the method that can readily occur in change should all cover in this hair Within bright protection domain, therefore repeat no more.
The embodiments of the invention provide a kind of video call method, compared to prior art, due to the first video Resolution ratio and frame per second when information is encoded are determined according to the Mean Speed of opposite equip. institute access network, Therefore when the Mean Speed of second terminal institute access network is higher, resolution ratio during the first video information coding Can be with larger with frame per second so that when second terminal network condition is preferable, more visible picture can be shown. Simultaneously as screen size of the first terminal according to network condition and second terminal, to the first video information Resolution ratio and frame per second have carried out multiple adjustment, at the same second terminal according to own net situation again to a video The resolution ratio and frame per second of information are adjusted so that when second terminal shows the first video information, higher Resolution ratio and frame per second under situations such as be not in interim card or asynchronous audio frequency and video, improve the sound of video calling Video quality, and then improve Consumer's Experience.
