Embodiment 3:

This embodiment further exemplifies the present invention by combining implementation manners of a specific application scenario.

In this embodiment, the EPG (Electronic Program Server) and the CDN (Content Distribution Server) of the IPTV platform can be accessed when the STB is the set top box with the LAN port (wired connection) and WIFI access (wireless connection), and the IPTV channel content and The content of the OTT channel exists at the same time, that is, the RTSP and the HLS content exist at the same time, and the content of different protocols needs to be played according to the current network access mode of the STB, mainly the channel content. In this embodiment, the EPG and JS modules of the IPTV platform (that is, the middleware module between the EPG and the set top box are deployed on the EPG) and the STB modules are implemented.

The specific mechanism is as follows:

1. The EPG sends the channelplayurltype (channel play URL type) switch to js, so as to support the simultaneous delivery of IPTV and OTT play addresses (namely URLs), as follows:

2. When the js channel information is sent, the parameter field ottcdnchannelcode can be added. When the EPG switch is turned on, the EPG sends the corresponding ott physical channel code (corresponding to the physical channel in the OTTChannelURL in the channel address structure).

An implementation of the js interface in this embodiment is as follows:

3. The js interface of the STB reading network connection mode in this embodiment is defined as follows:

Mode 1 is the LAN port network connection, STB preferentially plays the IPTV channel (RTSP/IGMP); Mode 2 is the WIFI connection, and STB preferentially plays the OTT channel (HLS).

4. After the channel plays the join channel ('xxx'), the streaming media reports that the virtual event indicates that the channel starts playing, and js determines whether it is a multicast channel. If it is multicast, set the timer for reporting the multicast start CDR. In order to record the multicast CDRs of the user when the LAN accesses and plays the IPTV multicast channel (because the OTT channel does not have multicast, there is no need to record the multicast CDR).

Based on the above settings, when the STB is logged in in this embodiment, the EPG server calls the telecom specification JS interface CTCSetConfig ('Channel', 'channlurlstruct') to deliver each channel play address structure to the STB.

The OTTChannelURL word is extended in the channel play address structure delivered by the EPG server. segment. The service platform preferentially writes the play URL of the IPTV in the ChannelURL and TimeShiftURL fields. If the Channel contains a PhysicalChannel of OTT, the OTT Play URL is written to the OTTChannelURL field value.

The processing on the STB side is as follows:

1. When the STB login receives the channel play address structure of CTCSetConfig (‘Channel’, 'channlurlstruct') from the service platform, it supports the parsing and saving of the extended OTTChannelURL field in the structure.

2. When the user chooses to play a channel, the STB obtains the channel play and time shift URL according to the following rules:

2.1) When the STB judges that the LAN network cable is connected, the field ChannelURL in the channel play address structure is locally searched as the channel play URL, and the field TimeShiftURL is taken as the channel time shift play URL and sent to the player.

2.2) When the STB judges that it is a WIFI connection, it preferentially searches for the field OTTChannelURL in the channel play address structure as the channel play and time shift URL. If the OTTChannelURL is empty or the field does not exist, then the ChannelURL is used as the channel play URL. TimeShiftURL is sent to the player as a channel time-shifting play URL.

2.3) When the STB judges that the WIFI and the LAN port are connected at the same time, the connection mode of the STB user setting or the STB's own default setting (for example, wired connection or wireless connection) shall prevail. After determining the connection mode, follow the above two methods. Get channel play and time-shift URL.

In addition, in this embodiment, during the channel play and time shift, when the network access mode changes, the type of the code stream is not switched, and the previously determined code stream type is still used. In this embodiment, after receiving a new play request (that is, after switching channels), the code stream type selected last time may be directly used, or the corresponding code stream type may be selected according to the current network access mode according to the foregoing process. Perform adaptive playback.

The above is a detailed description of the embodiments of the present invention in conjunction with the specific embodiments, and the specific embodiments of the present invention are not limited to the description. For those skilled in the art to which the present invention pertains, it can also be made without departing from the inventive concept. A number of simple deductions or substitutions are considered to be within the scope of the invention.
