Background
In the initial development stage of the IPTV set-top box, media data of a live channel is transmitted in a unicast manner. With the widespread application of IPTV service, in order to reduce the bandwidth pressure of the backbone network, operators gradually adopt a multicast mode to transmit media data. The multicast transmission network is constructed, multicast related configuration needs to be performed on each level of routing equipment, if a certain equipment node in the middle is not configured correctly or the multicast network is abnormal in the operation process, a multicast stream channel is abnormal, the IPTV set top box cannot normally receive multicast code stream media data, and finally a user cannot normally watch live programs.
In order to solve the problem, the current common method is that when a user starts up and plays a live broadcast channel for the first time, the user requests the multicast code stream media data of the live broadcast channel, and if the multicast code stream media data of the live broadcast channel is received within the preset time, the multicast code stream media data of the live broadcast channel is normally played; but if the multicast code stream media data of the live channel are still not received after the preset time, the unicast code stream media data of the live channel are requested. In such a processing flow, after the user starts up, the user needs to wait for a long preset time to play the live channel for the first time, which causes poor user experience.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and 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 application.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
Fig. 1 is a usage scenario diagram of a set top box according to an embodiment of the present application. As shown in fig. 1, a user may operate the set-top box 100 through the set-top box control device 400 and the display apparatus 200 through the display apparatus remote control device 500. The set-top box control apparatus 400 and the display device remote control apparatus 500 may be remote controllers, the communication between the remote controllers and the set-top box 100 includes infrared protocol communication or bluetooth protocol communication, and other short-distance communication methods, and the communication between the remote controllers and the display device 200 includes infrared protocol communication or bluetooth protocol communication, and other short-distance communication methods, and the display device 200 is controlled by wireless or wired methods.
The set-top box 100 and the display device 200 are each also in data communication with a server 300. The set-top box 100 and the display device 200 may be allowed to be communicatively connected through a Local Area Network (LAN), a Wireless Local Area Network (WLAN), and other networks. The server 300 may provide various contents and interactions to the display apparatus 200. The server 400 may be a cluster or a plurality of clusters, and may include one or more types of servers.
The set-top box 100 can access a network and perform interactive functions such as page information browsing and audio/video playing, and can provide services such as on-demand and watching, pause, fast forward, fast backward and other time shift functions for a user besides a live broadcast function.
After the IPTV set-top box is started, the IPTV set-top box interacts with the service management system through an HTTP protocol to complete the authentication process. After the authentication is passed, the service management system sends the live channel list information to the set top box.
The live channel list information includes a broadcast URL address of each live channel. The Play URL address may contain only one (e.g., rtsp://) or may contain more than one (e.g., igmp://////). When a plurality of playing addresses are contained, the set top box plays according to the sequence of the playing addresses, and tries to play by using the next playing address after one playing fails. The common operators can broadcast live broadcast in a unicast mode at the initial stage, and can switch to multicast broadcast after the multicast network environment is built at the later stage. The establishment of the multicast environment needs to process all levels of multicast replication points, sometimes, the multicast replication points are processed in a wrong way, so that the multicast network is obstructed, the multicast media data cannot be played normally, and a user cannot watch live broadcast normally. In order to be compatible with such a situation, when the service management system issues the live broadcast address, the service management system usually includes at least two broadcast addresses, i.e. broadcast address is igmp:///_ x/rtsp://.
And after acquiring the playing address of the channel in the live channel list information, the IPTV set top box sends a data request instruction to the content distribution system.
If the playing address of the channel is a multicast address (igmp:// >), the set-top box and the content distribution system interact through an igmp protocol; if the play address of the channel is a unicast address (rtsp://), the set-top box and the content distribution system interact through the rtsp protocol.
Because the protocol between the set-top box and the content distribution system is related to the broadcast address of the channel, and the content distribution system contains live broadcast media data, the content distribution system can only send the media data stream (multicast stream or unicast stream) to the set-top box after the interaction between the set-top box and the content distribution system is successful.
The IPTV set-top box live broadcast channel can be transmitted in a unicast mode or in a multicast mode. The current common method is that when a user plays a live broadcast channel for the first time after starting up, the user requests the multicast code stream media data of the live broadcast channel, and if the multicast code stream media data of the live broadcast channel is received within a preset time, the multicast code stream media data of the live broadcast channel is normally played; but if the multicast code stream media data of the live channel is still not received after the preset time, the unicast code stream media data of the live channel is requested. In the processing flow, after the user starts the device, the user needs to wait for a long preset time to play the live channel for the first time, which causes poor user experience.

The cache area 102 includes a first storage area 1021 and a second storage area 1022. The first storage area 1021 is used for storing a live channel list, and information in the live channel list is live channel list information. The live channel list information comprises a plurality of live channel information, and each live channel information is provided with a playing address corresponding to the live channel.
Since the live channel list information is stored in the first storage area 1021, and a live channel is included in the live channel list information, unicast stream media data or multicast stream media data of the live channel may also be stored in the first storage area 1021.
The second storage area 1022 is used for storing the multicast environment identifier. The multicast environment identifier is the first identifier or the second identifier. When the multicast environment identifier is the first identifier, the multicast environment is normal, that is, the cache region can receive the multicast code stream media data; when the multicast environment identifier is the second identifier, it indicates that the multicast environment is abnormal, that is, the cache region cannot receive multicast code stream media data, and can only receive unicast code stream media data of a live channel.

When the multicast environment identifier is the first identifier, the processor 103 sends a request data instruction to the multicast code stream server, the multicast code stream server sends multicast code stream media data of the current live broadcast channel, the multicast code stream server of the current live broadcast channel sends the multicast code stream media data to the first storage area 1021 of the cache area 102 through the network port 101, and the processor 103 reads the multicast code stream media data of the current live broadcast channel in the first storage area 1021, decodes the multicast code stream media data of the current live broadcast channel and plays the multicast code stream media data of the current live broadcast channel. When the multicast environment identifier is the second identifier, the processor 103 sends a request data instruction to the unicast stream server, the unicast stream server sends unicast stream media data of the current live channel, the unicast stream server of the current live channel sends the unicast stream media data of the current live channel to the first storage area 1021 of the cache area 102 through the network port 101, and the processor 103 reads the unicast stream media data of the current live channel in the first storage area 1021, decodes the unicast stream media data of the current live channel, and plays the decoded unicast stream media data of the current live channel.
In the application, the current live broadcast channel can be played quickly only by sending the request data instruction to the corresponding code stream server according to the multicast environment identifier, the multicast code stream media data of the current live broadcast channel do not need to be requested first, the unicast code stream media data of the current live broadcast channel can not be requested after the multicast code stream of the current live broadcast channel can not be received within the preset time, the time for playing the live broadcast channel for the first time after starting is effectively shortened, and the user experience is improved.
Prior to the playing of the current live channel, the processor 103 is further configured to: and responding to the starting instruction, and marking the multicast environment identification according to whether the multicast code stream media data of any live channel can be read within the preset time.
After receiving the boot instruction, the processor 103 interacts with the service management system via the HTTP protocol to complete the authentication process. After the authentication is passed, the service management system will issue the live channel list information to the set top box and store it in the first storage area 1021 of the cache area 102.
The processor 103 is further configured to: responding to a starting instruction, and sending a data request instruction to a multicast code stream server according to a multicast address of any live broadcast channel so as to enable the multicast code stream server to send multicast code stream media data corresponding to the multicast address; and when the multicast code stream media data corresponding to the multicast address is read within the preset time, marking the multicast environment identifier as a first identifier.
The processor 103 is further configured to: responding to a starting instruction, and sending a data request instruction to a multicast code stream server according to a multicast playing address of any live broadcast channel so as to enable the multicast code stream server to send corresponding multicast code stream media data; and when the multicast code stream media data corresponding to the multicast address is not read within the preset time, marking the multicast environment identifier as a second identifier.
The processor 103 obtains the multicast address of any live channel from the live channel list and sends a request data instruction to the multicast code stream server according to the multicast address. And the multicast code stream server sends multicast code stream media data corresponding to the multicast address according to the received request data instruction. When the processor 103 can read the multicast code stream media data of any live channel within a preset time, the multicast environment identifier is marked as a first identifier. And when the processor 103 does not read the multicast code stream media data of any live channel within the preset time, marking the multicast environment identifier as a second identifier.

And the multicast code stream server sends multicast code stream media data corresponding to the multicast address according to the received request data instruction. When the processor 103 can read the multicast code stream media data of any live channel within a preset time, the multicast environment identifier is marked as a first identifier. And when the processor 103 does not read the multicast code stream media data of any live channel within the preset time, marking the multicast environment identifier as a second identifier. When the multicast environment identifier is the first identifier, it indicates that the multicast environment is recovered to normal, that is, the buffer area 102 may receive the multicast code stream media data of the live channel, and the processor 103 updates the multicast environment identifier in the second storage area 1022 of the buffer area 102 from the second identifier to the first identifier. When the multicast environment identifier is the second identifier, it indicates that the multicast environment is still abnormal, that is, the buffer area 102 cannot receive the multicast code stream media data of the live channel, and the processor 103 identifies the multicast environment in the second storage area 1022 of the buffer area 102 as the second identifier.

And the multicast code stream server sends multicast code stream media data corresponding to the multicast address according to the received request data instruction. After reading the multicast code stream media data of the current live channel, the processor 103 obtains the unicast address of the current live channel from the live channel list, and sends a data stop instruction to the unicast code stream server according to the unicast address. And the unicast code stream server does not send the unicast code stream media data of the current program to the network port of the set top box according to the received stop data instruction.
