Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to shorten the time of a video playing interface in a buffer state and improve user experience, embodiments of the present invention provide a video playing method, apparatus, device, and medium.

Example 1:

fig. 2 is a schematic diagram of a first video playing process provided in an embodiment of the present invention, where the process includes the following steps:

s201: if the video playing interface of the intelligent television is monitored to be in a buffer state, a first bandwidth and a first IP address corresponding to a first device with the largest bandwidth, which is located in the same local area network, of the intelligent television are obtained.

The video playing method provided by the embodiment of the invention is applied to the smart television. In a possible implementation manner, if the video playing interface of the smart tv is in a buffering state, a buffering event (mediaplayer _ buffer) may be triggered, and after a service unit (network speed monitor _ Server) in the smart tv monitors the buffering event, it may be determined that the video playing interface of the smart tv is in the buffering state.

Because different devices in the same lan share a total bandwidth, if one of the devices occupies a larger bandwidth, the bandwidth occupied by other devices in the same lan will tend to decrease. When the video playing interface of the smart television is in a buffer state, the bandwidth occupied by the smart television can be considered to be less. In order to shorten the time that the video playing interface is in the buffer state, the smart television can obtain a first bandwidth and a first IP address corresponding to a first device with the largest bandwidth currently in the same local area network as the smart television.

When the first bandwidth and the first IP address corresponding to the first device are obtained, the first bandwidth and the first IP address corresponding to the first device with the largest current bandwidth may be determined according to the correspondence relationship between the bandwidths and the IP addresses of the multiple devices connected to the target gateway, which are stored in the target gateway in the same local area network as the smart television. In a possible implementation, if the correspondence between the network speeds and the IP addresses of the multiple devices is stored in the target gateway, the network speeds can be converted into bandwidths by using the prior art.

S202: and sending a first ARP request carrying a second IP address of a target gateway and a second MAC address of the intelligent television to the first equipment, wherein the target gateway and the intelligent television are in the same local area network.

Each device has its own IP address and dedicated MAC address, and when performing network communication, the peer device can be identified by the IP address at the network layer in the network protocol, and during the transmission of data packets at the data link layer in the network protocol, the peer device can be identified by the MAC address.

After the first device with the largest current bandwidth is obtained, in order to reduce the bandwidth occupied by the first device, a first ARP request carrying a second IP address of the target gateway and a second MAC address of the smart television may be sent to the first device. After receiving the first ARP request, the first device may store the second IP address and the second MAC address in the first ARP request in a first ARP cache table of the first device in order to respond to subsequent messages. At this time, the first device considers that the first ARP request is sent by the target gateway, and considers that the IP address and the MAC address of the target gateway are the second IP address and the second MAC address, respectively.

And the first equipment sends the data packet to the equipment with the second MAC address according to the corresponding relation between the second IP address and the second MAC address stored in the first ARP cache table, and at the moment, the first equipment sends the data packet which is supposed to be sent to the target gateway to the intelligent television according to the first ARP cache table because the second MAC address is the MAC address of the intelligent television.

S203: and sending a second ARP request carrying the first IP address and the second MAC address to the target gateway.

In order to enable the target gateway to consider the data packet as the data packet sent by the first device and to receive the data packet replied by the target gateway when the data packet sent by the first device is received and forwarded to the target gateway, the smart television may send a second ARP request carrying a first IP address of the first device and a second MAC address of the smart television to the target gateway.

After receiving the second ARP request, the target gateway may store the first IP address and the second MAC address in the second ARP request in a second ARP cache table of the target gateway in order to respond to subsequent messages. At this time, the target gateway considers that the second ARP request is sent by the first device, and considers that the IP address and the MAC address of the first device are the first IP address and the second MAC address, respectively.

And the target gateway sends the data packet to the equipment with the second MAC address according to the corresponding relation between the first IP address and the second MAC address stored in the second ARP cache table, and the second MAC address is the MAC address of the intelligent television, so that the target gateway sends the data packet which is supposed to be sent to the first equipment to the intelligent television according to the second ARP cache table.

S204: and if a data packet sent by the first equipment is received, determining a second bandwidth smaller than the first bandwidth, and sending the data packet to the target gateway by using the second bandwidth.

If the smart television receives the data packet, the data packet can be analyzed, whether the IP address carried in the data packet is the first IP address of the first device or not is judged, and if yes, the received data packet can be considered to be sent by the first device. For example, the data packet sent by the first device may be a Transmission Control Protocol (TCP) data packet, and a listening unit (socket) in the smart tv may listen whether an 8080 port of the smart tv receives the TCP data packet. If the data packet sent by the first device is received, the data packet can be forwarded to the target gateway so as to maintain network communication between the first device and the target gateway.

Because the first bandwidth occupied by the first device is larger at this moment, in order to improve the bandwidth occupied by the smart television, because the first device and the smart television are both in the same local area network, the sum of the first bandwidth occupied by the first device and the bandwidth occupied by the smart television is fixed, and if the first bandwidth occupied by the first device is reduced, the bandwidth occupied by the smart television can be correspondingly improved.

Therefore, after the smart television receives the data packet sent by the first device, in order to reduce the first bandwidth occupied by the first device, the data packet may be sent by using a second bandwidth smaller than the first bandwidth, and at this time, when the smart television sends the data packet by using the second bandwidth smaller than the first bandwidth, because the data packet is of the first device, it may be considered that the first bandwidth occupied by the first device is reduced, and the sum of the first bandwidth occupied by the first device and the bandwidth occupied by the smart television is fixed, so the bandwidth occupied by the smart television may be correspondingly increased.

It should be noted that the steps included in the video playing process are only an example, and the sequence between S202 and S203 is not limited in the embodiment of the present invention, that is, the sequence between the two steps is not limited, that is, the first ARP request carrying the second IP address of the target gateway and the second MAC address of the smart television is first sent to the first device, or the second ARP request carrying the first IP address and the second MAC address is first sent to the target gateway. Generally, in order to improve efficiency, the two steps S202 and S203 may be performed simultaneously.

Fig. 3 is a schematic diagram of a home lan network layout according to an embodiment of the present invention, as shown in fig. 3, after devices in the lan, such as an intelligent network device such as an intelligent Television (TV), a mobile phone, and a PC, are connected to a gateway, the devices may access network resources, the intelligent television may enable a first device corresponding to a first bandwidth to send a data packet to the intelligent television, and the intelligent television forwards the data packet sent by the first device to a target gateway with a second bandwidth smaller than the first bandwidth.

Specifically, when determining the second bandwidth smaller than the first bandwidth, the embodiment of the present invention does not specifically limit the specific values of the first bandwidth and the second bandwidth, and can flexibly select the second bandwidth according to the requirement. The first bandwidth may be multiplied by a factor less than 1, for example, to determine a second bandwidth that is smaller than the first bandwidth.

Example 2:

in order to determine the second bandwidth for transmitting the data packet, on the basis of the foregoing embodiment, in an embodiment of the present invention, the determining the second bandwidth smaller than the first bandwidth includes:

determining a third bandwidth currently occupied by the smart television;

In order to increase the bandwidth occupied by the smart tv, the bandwidth occupied by the first device may be reduced, in one possible implementation, as long as the bandwidth occupied by the first device is smaller than the first bandwidth. Because the first device and the smart television are both in the same local area network, and the sum of the bandwidth occupied by the first device and the bandwidth occupied by the smart television is fixed, if the bandwidth occupied by the first device is reduced, the bandwidth occupied by the smart television can be correspondingly increased.

When the second bandwidth occupied by the first device is determined, the bandwidth occupied by the first device can be appropriately reduced according to the relation between the third bandwidth currently occupied by the smart television and the first bandwidth currently occupied by the first device.

Specifically, the third bandwidth currently occupied by the smart television may be determined first, and when the third bandwidth currently occupied by the smart television is determined, the third bandwidth currently occupied by the smart television may be determined according to the bandwidth of the smart television stored in the target gateway in the same local area network as the smart television.

In addition, when the third bandwidth currently occupied by the smart television is determined, the third bandwidth currently occupied by the smart television can also be determined through a data node (/ proc/net/tx _ qtague/stats) in the smart television, that is, a bandwidth stored in a network card of the smart television. For example, the average value of the bandwidths stored in the data node may be used as the third bandwidth currently occupied by the smart television in the process of downloading (ThreadDown _ temporal) video files from the cloud resource by the smart television.

Illustratively, the smart television downloads a 500-megabyte video file from the cloud resource, and the data node stores a plurality of real-time bandwidths of the smart television in the whole process from the beginning to the end of downloading the video file. In order to accurately determine the third bandwidth currently occupied by the smart television, the average value of the plurality of real-time bandwidths of the smart television in the whole process from the beginning to the end of downloading the video file, which is stored in the data node, may be used as the third bandwidth currently occupied by the smart television.

After determining the third bandwidth currently occupied by the smart television, the ratio of the reduction of the first bandwidth may be determined according to a ratio of the third bandwidth currently occupied by the smart television to the first bandwidth of the first device. In a possible implementation manner, a ratio of the third bandwidth to the first bandwidth may be directly used as a reduction ratio of the first bandwidth, and after the reduction ratio of the first bandwidth is determined, a second bandwidth smaller than the first bandwidth may be determined according to the first bandwidth and the reduction ratio of the first bandwidth. Specifically, the product of the first bandwidth and the reduction ratio may be used as the second bandwidth.

After the bandwidth of the first device and the bandwidth of the smart television are reduced according to the reduction ratio, the bandwidth of the first device and the bandwidth of the smart television are interchanged, if the difference between the bandwidth of the first device and the bandwidth of the smart television is not large, the bandwidth of the first device is reduced by a small amount after the adjustment, and correspondingly, the bandwidth of the smart television is increased by a small amount, so that the adjustment effect may not be particularly good.

Therefore, in the embodiment of the present invention, the ratio of the third bandwidth to the first bandwidth may be determined, and then the ratio is divided by a positive number greater than 1 to determine the reduction ratio of the first bandwidth.

For example, the reduction ratio of the first bandwidth may be determined by the following formula:

ln＝(BW/DS)/n，

where ln is a reduction ratio to the first bandwidth, BW is a third bandwidth currently occupied by the smart television, DS is the first bandwidth of the first device, and n is a positive number greater than 1, for example, n may be 10, 20, and the like.

After the second bandwidth is determined, the bandwidth of the 8080 port of the smart television can be set as the second bandwidth through an entity rate limiting unit (iptable), so that the data packet is sent to the target gateway through the 8080 port in the second bandwidth. Specifically, the iptable may set the bandwidth of the 8080 port by executing a program (iptables-a FORWARD-s "MSD-IP" -m limit-limit "ln"/s-j ACCEPT).

Example 3:

in order to obtain a first bandwidth and a first IP address corresponding to a first device with a maximum bandwidth in the same local area network as an intelligent television, on the basis of the foregoing embodiments, in an embodiment of the present invention, the obtaining of the first bandwidth and the first IP address corresponding to the first device with the maximum bandwidth in the same local area network as the intelligent television includes:

At present, the gateway equipment provider does not provide the interface of the equipment information in the gateway to the terminal equipment provider, so the equipment information stored in the gateway cannot be acquired through the interface. However, since the device information stored in the gateway is stored in the management website of the gateway at the same time, in the embodiment of the present invention, the correspondence between the bandwidth and the IP address of each device connected to the target gateway can be acquired from the management website of the gateway.

In a possible implementation manner, the acquisition unit (Router _ Search _ Engine) in the smart television may acquire the corresponding relationship between the bandwidth and the IP address of each device connected to the target gateway from the management website of the gateway.

Specifically, after monitoring the buffering event, a service unit (network speed monitor _ Server) in the smart television triggers a control unit (TranDataNovService) in the smart television, so that the TranDataNovService controls the acquisition unit to acquire a corresponding relationship between a bandwidth and an IP address of each device connected to the target gateway from a management website of the gateway.

When acquiring the corresponding relationship between the bandwidth and the IP address of each device connected to the target gateway from the management website, an initial Uniform Resource Locator (URL) of the target gateway may be transmitted into a request library (request), where the initial URL of the target gateway is generally 192.168.0.1 or 192.168.1.1. The URL is parsed using a parsing library (beautilfsoup), thereby obtaining HyperText Markup Language (HTML) data information in a main page of a management website of the target gateway.

Then, the device information of each device connected with the target gateway is acquired by traversing the URL address in the sub-page (a-tag) of the management website of the target gateway, specifically, the acquired device information of each device at least includes a corresponding relationship between a bandwidth and an IP address, and may further include information such as an MAC address and a device ID.

In one possible implementation, in order to store the device information of each device connected to the target gateway, which is obtained from the management website, the Router _ Search _ Engine in the smart tv may store the device information of each device connected to the target gateway, which is obtained from the management website, as an extensible markup language (XML) file, and may store the device information as a Router _ date.

In a possible implementation manner, in order to verify the authenticity of the bandwidth of each device connected to the target gateway, which is obtained from the management website of the gateway, on the basis of the foregoing embodiments, in an embodiment of the present invention, before determining the first bandwidth with the largest bandwidth, the method further includes:

The bandwidth stored in the data node of the smart television can be considered to be real, so that a fifth bandwidth stored in the data node of the smart television in the same time can be acquired, a fourth bandwidth corresponding to the smart television acquired from the management website of the gateway is determined, and the authenticity of the bandwidth of each device connected with the target gateway acquired from the management website of the gateway is checked by comparing whether the difference value between the fourth bandwidth and the fifth bandwidth is smaller than a set threshold value.

Specifically, after the corresponding relationship between the bandwidth and the IP address of each device connected to the target gateway is obtained from the management website of the gateway, the fourth bandwidth corresponding to the smart television can be determined according to the corresponding relationship between the IP address, and the bandwidth of the smart television. And acquiring a fifth bandwidth saved in a data node (/ proc/net/tx _ qtaguid/stats) of the intelligent television.

Comparing the sizes of the fourth bandwidth and the fifth bandwidth, and if the difference value between the fourth bandwidth and the fifth bandwidth is smaller than a set threshold value, determining that the bandwidth of each device connected with the target gateway, which is acquired from the management website of the gateway, is credible.

The specific value of the set threshold can be flexibly set according to the requirement, for example, the set threshold can be ± 3KB, ± 2KB, etc. In general, the difference between the fourth bandwidth corresponding to the smart television acquired from the management website of the gateway and the fifth bandwidth stored in the data node of the smart television is no more than ± 3KB, so the threshold value may be set to ± 3KB, and if the difference between the fourth bandwidth and the fifth bandwidth is no more than the threshold value, the bandwidth of each device connected to the target gateway acquired from the management website of the gateway is considered to be authentic. And then, according to the corresponding relation between the bandwidth and the IP address of each device connected with the target gateway, which is acquired from the management website of the gateway, the first bandwidth with the maximum bandwidth can be determined by comparing the bandwidth of each device connected with the target gateway. And then determining the IP address corresponding to the first bandwidth as the first IP address.

Fig. 5 is a schematic diagram of a process for acquiring a corresponding relationship between a bandwidth and an IP address of each device connected to a target gateway and sending a data packet according to an embodiment of the present invention, as shown in fig. 5:

s501: and transmitting the URL of the target gateway into a request library.

Where the URL of the gateway is typically 192.168.0.1 or 192.168.1.1.

S502: and analyzing the URL by using an analysis library so as to obtain HTML data information in the main page of the management website of the target gateway.

S503: the device information of each device connected with the target gateway and stored in the management website of the target gateway is acquired by traversing the URL address in the sub-page (a-tag) of the management website of the target gateway.

The acquired device information of each device at least includes a corresponding relationship between a bandwidth and an IP address.

S504: and judging whether the URL addresses in the subpages (a labels) of the management website of the target gateway are traversed completely, if so, performing S505, and if not, performing S502.

S505: and saving the device information of each device connected with the target gateway, which is acquired from the management website of the target gateway, as router _ date.

S506: xml determines the fourth bandwidth corresponding to the smart tv from the router _ date, and step S508 is performed.

S507: and acquiring a fifth bandwidth saved in a data node (/ proc/net/tx _ qtaguid/stats) of the intelligent television.

S508: and comparing whether the difference value of the fourth bandwidth and the fifth bandwidth is smaller than a set threshold value or not to determine whether the bandwidth of each device connected with the target gateway acquired from the management website of the gateway is credible or not.

If the difference between the fourth bandwidth and the fifth bandwidth is smaller than the set threshold, it may be determined that the bandwidth of each device connected to the target gateway, which is acquired from the management website of the gateway, is trusted. In general, the difference between the fourth bandwidth and the fifth bandwidth is smaller than a set threshold, that is, the bandwidth of each device connected to the target gateway, which is acquired from the management website of the gateway, is generally trusted.

In a possible implementation manner, if the difference value between the fourth bandwidth and the fifth bandwidth is not less than the set threshold, the bandwidth of each device connected to the target gateway, which is currently acquired from the management website of the gateway, is considered to be untrustworthy. The bandwidth of each device connected with the target gateway can be obtained from the management website of the gateway again, and a fourth bandwidth corresponding to the smart television obtained from the management website of the gateway is determined; meanwhile, a fifth bandwidth stored in a data node of the smart television is obtained again, whether the difference value between the fourth bandwidth and the fifth bandwidth is smaller than a set threshold value or not is compared again until the difference value between the fourth bandwidth and the fifth bandwidth is smaller than the set threshold value, so that the subsequent step of determining the first bandwidth with the maximum bandwidth is carried out under the condition that the bandwidth of each device connected with the target gateway and obtained from a management website of the gateway is guaranteed to be credible.

S509: if the difference value between the fourth bandwidth and the fifth bandwidth is smaller than the set threshold value, according to the corresponding relation between the bandwidth and the IP address of each device connected with the target gateway, which is obtained from the management website of the gateway, the first bandwidth with the maximum bandwidth is determined by comparing the bandwidth of each device connected with the target gateway, and the IP address corresponding to the first bandwidth is determined as the first IP address.

In general, in order to verify the authenticity of the bandwidth of each device connected to the target gateway, which is obtained from the management gateway of the target gateway, in order to obtain the fourth bandwidth corresponding to the smart tv in the management website of the gateway and the fifth bandwidth stored in the data node of the smart tv at the same time, the steps S501-S506 and S507 may be performed simultaneously.

Example 4:

in order to quickly obtain the corresponding relationship between the bandwidth and the IP address of each device connected to the target gateway, on the basis of the above embodiments, in the embodiment of the present invention, the obtaining of the corresponding relationship between the bandwidth and the IP address of each device connected to the target gateway includes:

acquiring the IP address of each device stored in the target gateway;

Since there is a lot of device information stored in the management site of the gateway, for example, in addition to the correspondence between the bandwidth and the IP address of each device connected to the target gateway and the device information such as the device ID and the MAC address, there are also a lot of other information that is not related to the gateway, it takes time and is prone to errors if the correspondence between the bandwidth and the IP address of each device connected to the target gateway is found from such complicated device information.

In order to quickly and accurately acquire the corresponding relation between the bandwidth and the IP address of each device connected with the target gateway, the IP address of each device connected with the target gateway can be determined firstly, and then the corresponding relation between the IP address and the bandwidth can be quickly acquired from a plurality of pieces of device information stored in the target gateway according to the IP address, so that the efficiency of acquiring the bandwidth is improved.

In a possible implementation manner, in order to obtain the correspondence between the bandwidth and the IP address of each device connected to the target gateway, the IP address of each device stored in the target gateway may be obtained first. Specifically, the IP address of each device stored in the target gateway may be obtained by using the prior art. For example, the smart television converts an IP address of the target gateway, which is acquired through a Dynamic Host Configuration Protocol (DHCP), into a binary system, and performs bitwise and operation with a corresponding subnet mask, thereby acquiring an IP address of each device stored in the target gateway.

And after the IP address of each device stored in the target gateway is obtained, determining which devices corresponding to the IP addresses stored in the target gateway are the devices currently connected with the target gateway. Specifically, in order to obtain the device currently connected to the target gateway, an ARP request may be sent to the device corresponding to the IP address for each obtained IP address, where the ARP request carries the IP address corresponding to the device. And determining whether the equipment is the equipment which is currently connected with the target gateway according to whether the equipment returns the corresponding ARP response. Specifically, if receiving an ARP reply returned by the device corresponding to the IP address, the device corresponding to the IP address may be considered to be the device currently connected to the target gateway. The IP address of the device may be saved as a further xml file, for example as an actual IP.

After the device connected with the target gateway is determined, in order to quickly and accurately obtain the corresponding relationship between the bandwidth and the IP address of each device connected with the target gateway, the bandwidth corresponding to the IP address stored in the target gateway can be obtained according to the determined IP address of the device connected with the target gateway, so that the corresponding relationship between the bandwidth and the IP address of each device connected with the target gateway stored in the target gateway can be quickly and accurately obtained.

Wherein the determined IP address of the device connected to the target gateway may be saved as actual _ IP.

S604: in order to quickly acquire the corresponding relationship between the bandwidth and the IP address of each device connected to the target gateway, the corresponding relationship between the bandwidth and the IP address of each device connected to the target gateway may be quickly acquired from the router _ date.

In a possible implementation, since the corresponding relationship between the bandwidth and the IP address of each device connected to the target gateway, which is acquired from the management website of the gateway, is saved as a router _ date.xml file, a router _ date.xml file needs to be created first, and a certain time is consumed in the process of creating a router _ date. xml file, and in order to shorten the time that the smart television is in a buffer state, after the connection between the intelligent television and the target gateway is established, the corresponding relation between the bandwidth and the IP address of each device connected with the target gateway is obtained once, a router _ date.xml file is created, the corresponding relation between the bandwidth and the IP address of each device connected with the target gateway is stored in the router _ date.xml file, therefore, when the smart television is in a buffer state and the corresponding relation between the bandwidth and the IP address of each device connected with the target gateway is obtained, the corresponding relation between the bandwidth and the IP address stored in the router _ date.
