Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for acquiring streaming media data applied to a smart television according to an embodiment of the present invention, where the method for acquiring streaming media data is applicable to a smart television including a play control layer, a media player, and a channel service agent layer. As shown in fig. 1, the method for acquiring streaming media data applied to the smart television includes:
step 101, obtaining channel information of a broadcast channel by using a broadcast control layer, where the channel information at least includes any one of a channel identifier, a channel number, and a broadcast address of the broadcast channel.
The playing channel is a television channel currently played by the smart television, and may be a live channel or a carousel channel. Optionally, the channel identifier is a channel name of the channel.
Generally, after the smart television is turned on, when a live application or a carousel application installed in the smart television runs for the first time, a play control layer is created and initialized for the running application program, as shown in fig. 2. Wherein, the play control layer follows the activity lifecycle (including on create, on start, on resume, etc. states).
After the smart television is turned on, when the carousel application or the live application is first run, the smart television may directly load and play a certain live channel or a carousel channel, for example, the carousel channel may be a carousel channel last played when the smart television was turned off last time, and at this time, the play control layer corresponding to the running application program may directly obtain the channel identifier and/or the channel number of the channel (that is, the play channel).
Generally, the user can also select a channel to be played by the smart television through the control device. The intelligent television receives a control signal sent by the control equipment and generates a control instruction according to the control signal. And when the control instruction is used for instructing channel switching, sending the control instruction to a playing control layer. The playing control layer receives the control instruction, and acquires the channel identifier or the channel serial number of the playing channel according to the control instruction, wherein the playing channel is the channel selected by the user for playing. Wherein the control device may be a remote control or other mobile device (e.g., a smartphone).
For example, the number of the channel being played by the smart television is 15. When the smart television receives an infrared signal sent by a remote controller and used for indicating switching to a next channel, a control instruction corresponding to the signal and used for indicating switching to the next channel is sent to the playing control layer, and then the playing control layer can determine that the channel serial number of the playing channel selected by a user for playing is 16.
Taking the channel identifier as the channel name for example, the smart tv may provide a live channel selection interface to the user, as shown in fig. 3. The user may use the remote control to move the cursor over the channel name of the cardioverter channel. When the smart television receives a signal for indicating the determination of the selection, the determination instruction is sent to the playing control layer, and the playing control layer can determine that the playing channel selected by the user for playing is an international sports channel.
Optionally, after the playing control layer obtains the channel identifier or the channel serial number of the playing channel, the playing control layer may also query the playing address of the playing channel according to the channel identifier or the channel serial number. The broadcast address is usually a Uniform Resource Locator (URL) of the server corresponding to the broadcast channel.
Generally, an Electronic Program Guide (EPG) information records a channel number, a channel identifier, and a broadcast address of each channel. The playing control layer may query the EPG information for the obtained playing address corresponding to the channel identifier or the channel number, that is, the playing address of the playing channel selected by the user for playing.
102, sending the channel information to a channel service agent layer by using a play control layer, acquiring a play address of a play channel according to the channel information by using the channel service agent layer, and establishing a hypertext transfer protocol (HTTP) connection with a server with the play address.
The sending of the channel information to the channel service agent layer by using the play control layer can be implemented by the following two possible implementation manners.
In a first possible implementation, the play control layer is used to send the channel information directly to the channel service agent layer.
As shown in fig. 4, after acquiring the channel number or the channel identifier, the play control layer may directly send the acquired channel identifier or channel signal to the channel service agent layer. The playing control layer may also determine a playing address of the playing channel according to the obtained channel number or the channel identifier, and then directly send the playing address to the channel service agent layer.
In a second possible implementation manner, the playing control layer obtains the playing address of the playing channel according to the channel information, sends the playing address to the media player, and sends the playing address to the channel service agent layer by using the media player.
After receiving the playing address from the playing control layer, the media player can directly send the playing address to the channel service proxy layer, and the channel service proxy layer downloads the real-time streaming media data of the playing channel from the server.
Further, after the smart television obtains the broadcast address of the broadcast channel by using the channel service agent layer, the smart television establishes a Hyper Text Transfer Protocol (HTTP) connection with the server having the broadcast address by using the channel service agent layer.
Step 103, before the media player enters the playing state, the channel service proxy layer is used to download at least part of streaming media data of the playing channel from the server with the playing address.
Generally, before the media player enters the playing state, the smart tv may send the channel information to the channel service proxy layer by using the playing control layer or the media player, so that the channel service proxy layer obtains the playing address of the playing channel before the media player enters the playing state, and downloads the streaming media data of the playing channel from the server having the playing address. Therefore, before the media player enters the playing state, the channel service proxy layer downloads part of the streaming media data from the server with the playing address.
The streaming media data of the playing channel is streaming media data provided by the server in real time for the channel, and the streaming media data provided by the server in real time is streaming media data which needs to be played by the playing channel at the current moment.
Streaming media data provided by a server in real time is generally composed of a plurality of slice files. Generally, the server generally provides a second playlist for a broadcast channel, where the second playlist includes a Uniform Resource Identifier (URI) of a slice file corresponding to streaming media data that needs to be broadcast by the broadcast channel.
In addition, the server updates the second playlist according to the streaming media data which needs to be played at the current time of the playing channel.
Correspondingly, the intelligent television acquires a second play list of the playing channel from the server by using the channel service agent layer, the second play list is used for recording the URIs of the plurality of slice files, and the slice files are downloaded by using the channel service agent layer according to the URIs in the second play list.
In addition, the smart television also sends a second play list corresponding to the downloaded slice file to the media player, so that the media player can obtain each slice file according to the second play list.
And step 104, after the media player enters a playing state, acquiring the streaming media data downloaded by the channel service proxy layer in real time from the channel service proxy layer by using the media player.
Still referring to fig. 2, after the media player enters the playing state, the media player may start playing the streaming media data, and at this time, the media player obtains the streaming media data downloaded by the channel service proxy layer from the channel service proxy layer for playing.
It should be noted that, when the media player enters the playing state, the channel service agent layer does not interrupt the downloading of the streaming media data of the playing channel. That is, after the media player enters the playing state, the streaming media data of the playing channel is still downloaded from the server in real time by the channel service agent layer.
Optionally, step 104 may also be replaced by: after the media player enters a playing state, the media player is used for acquiring the streaming media data downloaded by the channel service proxy layer from the channel service proxy layer, and the streaming media data of the playing channel which is not downloaded by the channel service proxy layer is downloaded in real time from the server with the playing address.
Before the media player enters the preparation state, the streaming media data of the playing channel is downloaded in real time by the channel service agent layer. After the media player enters the preparation state, the intelligent television does not use the service agent layer to download the streaming media data of the playing channel in real time, and uses the media player to download the streaming media data of the playing channel in real time.
In summary, the method for acquiring streaming media data applied to a smart television according to the embodiments of the present invention acquires channel information of a broadcast channel by using a broadcast control layer, and sends the channel information to a channel service agent layer by using the broadcast control layer, before a media player enters a broadcast state, the channel service agent layer acquires a broadcast address of the broadcast channel according to the channel information of the broadcast channel, and the channel service agent layer downloads at least a part of streaming media data of the broadcast channel from a server having the broadcast address; the smart television can acquire the playing address of the playing channel by using the channel service agent layer before the media player enters the playing state, and stream media data are downloaded from the server with the playing address, so that the stream media data can be downloaded from the server with the playing address without waiting until the playing control layer is initialized and the complex process before the media player enters the playing state is finished, the problem that the speed of the stream media data are loaded for the first time by live broadcast application or carousel application in the related technology is low is solved, and the effect of improving the speed of the stream media data loaded for the first time by the live broadcast application or carousel application is achieved.
Optionally, after the HTTP connection is established between the channel proxy service and the server corresponding to a channel, the corresponding relationship between the broadcast address of the channel and the channel identifier or the channel number may be recorded in the first playlist. The first playlist is used for recording the playing address of the channel which is loaded by the channel service agent layer history.
Correspondingly, when the channel information received by the intelligent television by using the channel service agent layer is not a broadcast address, the channel service agent layer is used for inquiring the broadcast address corresponding to the channel information in the first broadcast list, wherein the channel information is a channel identifier or a channel serial number of a broadcast channel.
If the channel proxy server does not inquire the playing address of the playing channel in the first playing list, the playing address corresponding to the channel identifier or the channel serial number can be inquired in the EPG information to obtain the playing address of the playing channel.
Because the information data recorded in the EPG information is huge, the acquisition speed of the playing address can be increased by inquiring the playing address of the playing channel in the first playing list.
Alternatively, downloading the streaming media data of the broadcast channel from the server having the broadcast address by using the channel service proxy layer may also be implemented through several steps as shown in fig. 5.
Step 501, a channel service proxy layer is used to obtain a second playlist of a broadcast channel from a server having the broadcast address, where the second playlist is used to record URIs of multiple slice files provided by the server.
Step 502, at least two loading threads are created, and the at least two loading threads are used for downloading corresponding slice files according to URIs respectively.
The plurality of threads are started to simultaneously download the slice files corresponding to the URI, so that the downloading speed of the streaming media data is improved, and the jam of the audio and video data is reduced.
The intelligent television can download the streaming media data of the playing channel which is playing, and can also preload the streaming media data of other channels. For example, the preloaded channel may be a channel with a channel number adjacent to the channel number of the broadcast channel; for another example, preloading channels in a favorites list; for another example, the channel with the longest history playing time is preloaded. In particular, this can be achieved by several steps as shown in fig. 6.
Step 601, determining a channel adjacent to the playing channel as a preloaded channel, and sending a channel serial number of the preloaded channel to a channel service agent layer, where the channel serial number of the channel adjacent to the playing channel is adjacent to the channel serial number of the playing channel.
For example, if the channel number of the playing channel currently being played by the smart television is 15, the channel corresponding to the channel number 16 and the channel corresponding to the channel number 14 are determined as the preloaded channels, and the channel number 16 and the channel number 14 may be sent to the channel service agent layer.
Step 602, counting the historical playing time of each channel, determining the channel with the longest historical playing time as the preloaded channel, and sending the channel number or the channel identifier of the preloaded channel to the channel service agent layer.
The smart television can count the historical playing time of each channel. After the intelligent television is started, the channel with the longest historical playing time is obtained, and the channel serial number or the channel identification of the channel is sent to the channel service agent layer.
Step 603, determining the channel in the favorite list as a preloaded channel, and sending the channel number or the channel identifier of the preloaded channel to the channel service agent layer.
Some smart televisions have a channel collection function, and a user can collect channels by using the channel collection function provided by the smart television. Accordingly, the user can view or select the collected channels in the favorite list provided by the smart television.
After the smart television is started, the smart television can determine the channels in the favorite list as the preloaded channels, and send the channel serial numbers or the channel identifications of the preloaded channels to the channel service agent layer.
Step 604, downloading real-time streaming media data from the server corresponding to the preloaded channel by using the channel service agent layer.
The smart television can utilize the channel service agent layer to acquire the playing address of the preloaded channel according to the channel identification or the channel serial number, and establish HTTP connection with the server with the playing address.
The implementation that the smart television uses the channel service agent layer to download the streaming media data of the preloaded channel from the server corresponding to the preloaded channel may refer to the explanation of downloading the streaming media data of the playing channel in step 103, and details are not described here.
The pre-loading channel is usually a channel to which a user may switch, streaming media data is pre-loaded on the pre-loading channel, and when the user controls the smart television to play the pre-loading channel, a media player corresponding to the pre-loading channel enters a playing state and then can directly acquire and play the streaming media data downloaded by the pre-loading channel from the channel service agent layer.
Optionally, when the number of the slice files corresponding to the downloaded preloaded channel reaches a predetermined number, part of the slice files are deleted. The partial slice file referred to herein may be a predetermined number of slice files that are sorted in the downloaded slice file in the playing order. Wherein the predetermined number is typically set by a system developer.
The following are embodiments of the apparatus of the present invention, and for details not described in detail in the embodiments of the apparatus, reference may be made to the above-mentioned one-to-one corresponding method embodiments.
