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 application.
The embodiment of the application discloses a 4K video playing method, which is applied to a television, and is used for sending a 4K video request to a set top box through usb-dongle equipment so as to enable the set top box to send the 4K video request to a server, obtaining 4K video data from the server, receiving the 4K video data sent by the set top box through the usb-dongle equipment, decoding and playing the 4K video data, and realizing decoding and playing of 4K videos.
The execution of the 4K video playing method provided by the application depends on brand new arrangement of a television and a set top box, and the specific arrangement is as follows:
1. hardware link layer:
the usb device is used as the external device for connection and communication, and the usb device has the functions of plug and play and hot plug, so that the set top box and the television can be conveniently powered off, and necessary initialization work can be completed by detecting plug events.
Because the usb is a working mode of a master device and a slave device, the host device carries out arbitration to determine when to carry out read-write operation, and the host terminal supplies power, the set-top box and the television set in the invention both work under the host mode, a common direct usb wire can not work, and a converter with a slave device function is needed at this moment, based on the device, the usb-dongle device which can be adopted by the application can be used, the hardware connection mode of the device can be seen in figure 1, as shown in figure 1, one end of the usb-dongle device is connected with the set-top box, the other end of the usb-dongle device is connected with the television set, the usb-dongle device can read or write at one end of the set-top box, the usb-dongle device can also read or write at one end of the television set, but the usb-dongle device is in one-way transmission, and the usb-dongle device only has one data storage space, if one end switches the transmission direction, data is written, then the other end can only read the data.
It should be noted that some necessary initialization tasks performed by detecting the plugging event may include:
the set-top box: the set-top box has a daemon usbserver, loads sdk library after starting up, adds a virtual network card, configures the ip address of the set-top box tun0 (for example, iptables-t nat-APOSTROUTING-s 10.0.0.1/8-o eth0-j MASQUERED 10.0.1), starts up the network forwarding function, establishes the mapping relation between the virtual network card and the physical network card, forwards the network data of the virtual network card through the physical network card, simultaneously returns the data to be received through the physical network card and sent to the virtual network card (namely, the data of tun0 is sent through eth0, after the return data is received by eth0, judges whether the mapping table is the return data sent by tun0, then determines whether to forward to tun0), registers the state monitor of usb-dongle equipment, and constructs the network configuration parameters of the television end.
The step of initializing the set-top box after the set-top box is turned on may include:
and A, opening the usb-dongle device to complete the initialization of the device.
B, waiting for the on-line message of the opposite terminal (such as a television) device.
C, enabling the opposite terminal equipment to be on line, and starting two circulation working threads: one is responsible for reading the data of the usb-dongle device and writing the data into the virtual network card (e.g., tun0), and the other is responsible for reading the data of the virtual network card (e.g., tun0) and writing the data into the usb-dongle device, and transmitting the network configuration parameters at the television end to the television.
A television set:
1. a: creating a virtual network card tun0
b, configuring a routing environment through the busy route add-net 0.0.0.0dev tun0 or other commands to ensure that all network data are transmitted through the virtual network card tun 0.
2. The television system downloads and installs the service application program (such as UsbVpnservice) developed for normal work of the usb-dongle equipment, and when the specified usb-dongle equipment is inserted into the television, the television system can start the service application program (such as UsbVpnservice), open the usb-dongle equipment, initialize the usb-dongle equipment, build a vpn environment, and start two cycle working threads as the set top box: reading the configuration parameters sent by the set top box end, and setting a television end network, so that other application programs at the television end can surf the internet through the vpn environment built by usb-dongle equipment. After the vpn environment is built, the network data of the network playing application can be transmitted through the virtual network card tun0, and a service application program (for example, usbbpnservice) can read the network data of the virtual network card tun0 and write the network data into usb-dongle.
It should be noted that the television may be an Android/Tvos 4k smart television. But not limited to, other TV systems (e.g., Apple TV system) as long as the vpn environment established by the system can be built.
