Embodiment Construction
[0051] figure 1 It is a schematic flowchart of a satellite transmission data navigation method according to an embodiment of the present invention; figure 1Navigation methods for satellite-transmitted data shown in , including:
[0052] Step 301, setting the sending device channel. Specifically, each group of headend 10 , packer 70 and multiplexer 80 is configured to push one or more guide parts 201 or navigation parts 202 . Each content distribution system 90 is configured to push one or more target data 601 . The headend 10 acquires the configuration information and configures the information category and transmission channel of the target data 601, and then generates a corresponding XML file.
[0053] Step 302, setting the first part of navigation information. In this step, the extension unit records the acquisition path of the XML file.
[0054] Step 303, setting the second part of navigation information. In this step, the content of the XML file is set, and the XML ...

The invention relates to the field of satellite broadcasting, in particular to a navigation method and a navigation system for satellite transmission data. The navigation method of the satellite transmission data includes: a, setting the navigation information composed of the guide part and the navigation part, the extension unit records the acquisition route of the XML file; the navigation part contains the XML file, and the XML file records the acquisition route and information of the target data Category; the head end uploads the navigation information to the satellite, the guidance part is broadcast to the terminal through the satellite, and the content distribution system uploads the target data and information category to the satellite. Since the XML file in the navigation part is used to record the acquisition method and information category of the target data, the management operations of adding or deleting the target data and information categories can be centralized as needed, and the completed navigation information can be edited according to the needs of the head-end managers. The operation of addition and deletion is performed without having to recreate the navigation information every time, which greatly reduces the update time of the navigation information.
Description
technical field [0001] The invention relates to the field of satellite broadcasting, in particular to a navigation method and a navigation system for satellite transmission data. Background technique [0002] In the context of the rapid development of broadcast television networks and the Internet, content service operators have a large amount of media content in various forms (live, offline content) and in different categories (music, video). The head-end is used to push the non-real-time target data to the terminal via satellite. With the support of the head-end, the user can use the existing hard disk, interactive channel and set-top box to passively receive or download these target data to the hard disk, and then perform local on-demand . In order to enable users to find the required information conveniently and quickly among the numerous information, the DVB set-top box provides navigation information. The human-computer interaction interface composed of text, graphic...
