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.
For the understanding of the present embodiment, the following detailed description will be given of the embodiments of the present invention.
The first embodiment is as follows:
fig. 1 is a schematic view of an application scenario of a live video sharing method based on an IPTV terminal according to an embodiment of the present invention.
Referring to fig. 1, a server is applied in a public network, and an IPTV terminal and a client are applied in a local network. The server side comprises an authentication server, a service management server and a streaming media server.
The IPTV terminal is a device which is issued to a user by an IPTV service operator, and after the IPTV service is opened, the IPTV terminal can access a service terminal to acquire services such as IPTV live broadcast and the like.
The service end is a group of servers maintained and managed by an IPTV service operator, and provides services such as authentication, service management, streaming media push and the like for the IPTV terminal.
The client is a terminal device such as a mobile phone, a tablet Computer, a notebook Computer, and a PC (Personal Computer) of the user. The devices are located in a local area network with the IPTV terminal device.
The second embodiment:
fig. 2 is a flowchart of a live video sharing method based on an IPTV terminal according to a second embodiment of the present invention.
Referring to fig. 2, the IPTV terminal includes a video sharing service module and an IPTV application module, and the method includes the following steps:
step S101, after login authentication is successful, a video sharing service module sends live video sharing service information to a client so that the client establishes connection with an IPTV terminal according to the live video sharing service information, wherein the live video sharing service information comprises an IP address and a service port of the IPTV terminal;
here, the authentication procedure of the IPTV terminal includes: the IPTV terminal carries the service account number, the password and the terminal serial number information to initiate an authentication request to an authentication server of the server side, and the authentication server returns an authentication result after passing the verification. After the IPTV terminal is successfully authenticated, the IPTV terminal requests a live channel list to the server and caches the live channel list in the service management module, and the subsequent agent module can directly return the cached channel list when requesting the channel list.
Step S102, a video sharing service module receives channel list request information sent by a client, and the channel list request information is sent to a server through an IPTV application module, so that the server obtains a channel list according to the channel list request information;
step S103, the IPTV application module receives a channel list sent by the server and sends the channel list to the client through the video sharing service module;
step S104, the video sharing service module receives channel live stream request information sent by the client, and the channel live stream request information is sent to the server through the IPTV application module, so that the server obtains a live stream according to the channel live stream request information;
step S105, the IPTV application module pulls the live stream sent by the server side, and processes the live stream to obtain a processed live stream;
and step S106, the IPTV application module re-encapsulates the processed live stream to obtain an encapsulated live stream, and the video sharing service module sends the encapsulated live stream to the client so that the client plays the encapsulated live stream.
Here, the application utilizes the original live broadcast service of the IPTV terminal, first queries the network encapsulation format supported by the client player, and then re-encapsulates the live broadcast streams in different encapsulation formats received by the IPTV terminal into the encapsulation format supported by the client, so that the application is compatible with various different client devices, and greatly simplifies the software adaptation work of various types of client devices. The ordinary client device also indirectly supports various modified or expanded network encapsulation protocols of IPTV industries such as RTSP/RTMP (Real Time Messaging Protocol)/HTTP (Hypertext Transfer Protocol)/IGMP/HLS and the like through the IPTV terminal agent, and can be compatible with various IPTV streaming media servers.
Further, referring to fig. 3, the video sharing service module includes a service discovery module, and step S101 includes:
the service discovery module sends live broadcast video sharing service information to the client through an mDNS (Multicast DNS) protocol or a UPnP (Universal Plug and Play) protocol, so that the client searches an IP address and a service port of the IPTV terminal in a local area network shared by IPTV live broadcast according to the mDNS protocol or the UPnP protocol and establishes connection with the IPTV terminal according to the IP address and the service port.
Specifically, after the IPTV terminal successfully authenticates and acquires a channel list, a live video sharing service module is started, a service publishing module publishes the service to other terminal devices in a local area network through protocols such as mDNS/UPnP, a client of IPTV live sharing in the local area network searches an IP address and a port number of the IPTV live sharing service in the local area network in which the IPTV live sharing is started through a service detection method of the protocols such as mDNS/UPnP, and after the client finds the IP address and a service port of the IPTV live sharing service, the client of the IPTV live sharing service is connected to an agent module of the IPTV live sharing service through the IP address and the service port, and requests the channel list and the live stream from the agent module.
According to the method and the device, the live video sharing service is released and found in the local area network through protocols such as mDNS/UPnP, and the live video sharing service can be rapidly experienced without manually configuring IPTV terminal information by a user.
Further, the video sharing service module further includes an agent module, the IPTV application module includes a service management module, and step S102 includes:
the proxy module receives the channel list request information sent by the client, and sends the channel list request information to the service management server of the server through the service management module, so that the service management server of the server obtains the channel list according to the channel list request information.
Further, step S103 includes:
and the service management module receives a channel list sent by a service management server of the server side and sends the channel list to the client side through the proxy module.
Further, the method comprises the following steps:
step S201, when the proxy module sends the channel list request information to the service management module again, obtaining the channel list from the cache of the service management module, and sending the channel list to the client through the proxy module.
Here, the client may send the channel list request information to the proxy module through HTTP or HTTPs, and after receiving the channel list request information, the proxy module forwards the channel list cached by the service management module to the client and displays the channel list to the client interface.
Further, the IPTV application module further includes a streaming media processing module and a stream pushing module, and step S104 includes:
the proxy module receives channel live stream request information sent by the client, and sends the channel live stream request information to the server through the stream pushing module and the stream media processing module in sequence, so that a stream media server of the server obtains a live stream according to the channel live stream request information.
After a user selects a certain live broadcast channel in a channel list of a client, the client requests a proxy module of an IPTV terminal for the live broadcast stream through HTTP or HTTPS, and after receiving the request information of the channel live broadcast stream, the proxy module notifies a streaming media processing module of the IPTV application module to pull the live broadcast streams such as RTSP/RTMP/HTTP/IGMP (live broadcast stream in multicast mode)/HLS from a streaming media server of a server.
Further, step S105 includes:
the streaming media processing module pulls the live streaming sent by the streaming media server of the server, and the live streaming is subjected to ARQ (automatic repeat request), FEC (forward error correction) or FCC (fluid catalytic cracking) processing to obtain the processed live streaming.
Specifically, when the RTSP live stream is pulled, the streaming media processing module performs ARQ automatic retransmission request processing, actively informs the streaming media server of which network packets are lost, and the streaming media server reissues the lost packets, thereby avoiding video blocking and screen splash caused by lost packets.
When the IGMP multicast stream is pulled, the streaming media processing module performs FEC forward error correction or/and FCC fast station switching: when the multicast packet is pushed by the multicast streaming media server, a redundant error correction packet generated by encoding the multicast packet is pushed at the same time, the streaming media processing module receives the multicast network packet, and if the packet is lost, the lost network packet is recovered by decoding the error correction packet through a forward error correction algorithm, so that video card pause and screen splash caused by the packet loss are avoided; when the broadcasting is started, the streaming media processing module and the FCC server interactively acquire a unicast stream of a section of first frame, namely an I frame, and then the unicast stream is transited to a multicast stream, so that the bandwidth of the server is saved while the channel is quickly switched.
According to the method and the device, through the IPTV terminal proxy, common client equipment can also indirectly support protocols such as ARQ/FEC/FCC, the characteristics of packet loss retransmission, automatic error correction and rapid multicast switching in a weak network environment are indirectly obtained, and the playing fluency and the playing starting speed of the client are improved. Meanwhile, the application demonstrates complete functions at the customer of the IPTV service operator, and the operation is good.
