The embodiment of the invention provides a digital television live broadcasting method based on network playing equipment, wherein the network playing equipment which is connected with a live broadcasting set-top box and a video playing device through a physical connecting line is electrified and automatically started, communication connection with the live broadcasting set-top box is established, a live broadcasting application program is started, and the live broadcasting application program is controlled to connect a started command receiving service and a video sharing service on the live broadcasting set-top box; after the video playing device is powered on, when a first key value is obtained, if the first key value is characterized as a live broadcast request aiming at a live broadcast channel, the video playing device executes by utilizing a live broadcast application program: based on the command receiving service, sending a corresponding video playing command to a set top box for live broadcasting so as to return a corresponding live broadcasting code stream; receiving the live broadcast code stream based on a video sharing service; and controlling the video playing device to play the digital television broadcasting program of the live broadcast channel according to the live broadcast code stream. The embodiment of the invention realizes the function of watching the digital television broadcast on the network playing equipment.
In detail, the network playing device is a physical entity which can be connected to the network for playing video. For example, the network playing device may be a set-top box for on-demand, so that the network playing device may have two video playing functions of on-demand and live broadcasting.
Although the set-top box for on-demand broadcasting can also realize live video broadcasting through the installed live broadcasting software, the live video resource is from the network, not from the broadcast television operator, so the live broadcasting effect is poor. The digital television live broadcast implementation mode provided by the embodiment of the invention can play live broadcast video from broadcast television operators based on network playing equipment, and has good live broadcast effect.
In an embodiment of the present invention, when the network playing device is a set-top box for on-demand, the network playing device may be an OTT set-top box or a Dongle.
In detail, Dongle, or Dongle set-top box, is a product that can play a role of network video on demand, and may also be called a smart Dongle.
In detail, this live set-top box may be a DVB set-top box. The DVB set-top box can be a set-top box of DVB-C, DVB-S/S2 and DVB-T/T2 standards.
Taking a Dongle and a DVB set-top box as examples, since the Dongle does not have resources such as a modem and a descrambler, the playing of digital video broadcasting cannot be realized when video playing is performed only by the Dongle, but in the embodiment of the present invention, the digital video broadcasting program can be played on the Dongle by borrowing resources such as a modem and a descrambler of the DVB set-top box.
Typically, this digital video broadcast may be a digital video broadcast of the DVB-C/DVB-S2/DVB-T standard.
In the embodiment of the invention, as the network playing equipment needs to borrow software and hardware resources of the set top box for live broadcast to realize live broadcast of the digital television and needs to display live broadcast programs based on the video playing device, physical line connection among the network playing equipment, the set top box for live broadcast and the video playing device is firstly established. Furthermore, in order to borrow the software and hardware resources of the set top box for live broadcasting by the network playing device, communication connection and service connection between the network playing device and the set top box need to be established.
The network playing device is a Dongle, the set-top box for live broadcasting is a DVB set-top box, and the video playing device is taken as an example.
For physical line connections, it is possible to connect television and Dongle through HDMI connection lines and Dongle and DVB set-top boxes through USB connection lines. Thus, the DVB set-top box can supply power to Dongle through the USB connection.
For the communication connection and the service connection, the two connections are usually connected for the first time, that is, the network playing device performs the communication connection and the service connection each time it is powered on, that is, the above steps 101 to 104 are performed only each time the network playing device is powered on. In the live process of the network playing equipment, no matter how the video playing device is switched on or switched off, the network playing equipment does not execute communication connection and service connection any more.
In detail, for service connection, in order to implement command transmission and live video streaming transmission between the network playing device and the live set-top box, the network playing device should connect a command receiving service and a video sharing service of the live set-top box. After the services are connected, both subsequent command transmission and live video stream transmission can be achieved based on the connected corresponding services.
In the case that the above three connections are completed, the above steps 105 and 106 can be performed as required each time the video playing apparatus is powered on.
Corresponding to the step 106, when the user needs to watch the live program of a live channel, taking the network playing device as Dongle, the live set-top box as DVB set-top box, and the video playing device as the television as examples, the user can control the remote controller as required according to the information displayed on the television to send out a corresponding live request. For example, the user needs to watch the live program of CCTV-1, so the user can control the remote controller to make the cursor fall on the option of CCTV-1 and trigger the confirm key. Thus, the Dongle can send the video playing command aiming at the CCTV-1 to the DVB set top box so as to return the CCTV-1 live video stream and control the television to play the live video stream.
Here, at least the following two cases may exist:
case 1: a user operates a remote controller of the network playing equipment to send out a live broadcast request;
case 2: the user operates the remote controller of the set top box for live broadcasting to send out a live broadcasting request.
In detail, the user may cause the remote controller to transmit a corresponding key value by manipulating a down, left, right, confirm, etc. key on the remote controller. The first key value sent by the remote controller of the network playing device can be directly sent to the network playing device, and the second key value sent by the remote controller of the set top box for live broadcasting needs to be forwarded to the network playing device through the set top box for live broadcasting, and the network playing device converts the second key value into the first key value.
In detail, corresponding to case 1 above:
in an embodiment of the present invention, when obtaining a first key value, the method includes: and when a first key value sent by a remote controller corresponding to the network playing equipment is received.
In detail, corresponding to case 2 above:
in an embodiment of the present invention, when obtaining a first key value, the method includes: and when a second key value sent by the set top box for live broadcasting is received and the second key value is converted into a first key value.
In detail, in case 2, a live broadcast request sent by a remote controller of the live broadcast set-top box is first sent to the live broadcast set-top box, and the live broadcast set-top box forwards the live broadcast request to the network playing device, so that the network playing device generates a corresponding video playing command. And then, the network playing equipment sends the video playing command to the set top box for live broadcasting so as to return a corresponding live broadcasting code stream.
In detail, the set top box for live broadcasting can send the obtained code rate to the network playing device after operations such as frequency locking, descrambling and recording are performed in sequence.
In summary, both the OTT set-top box and the Dongle can use the hardware and software of the DVB set-top box to realize the playing of the digital video broadcasting of the DVB-C/DVB-S2/DVB-T standard. In addition, since the DVB set-top box is connected, the OTT set-top box can be controlled or the Dongle can be controlled by using the remote controller of the DVB set-top box in addition to the remote controller of the network playing device.
In the embodiment of the invention, the network playing equipment is respectively connected with the set top box for live broadcasting and the video playing device, and the network playing equipment can support the basic functions of the network playing equipment, such as the basic video on demand function and can realize the additional video live broadcasting function based on the digital television live broadcasting realization mode.
