Embodiment 1

[0050] combined with figure 1 and figure 2 As shown, a video distribution method based on the cable home gateway, including the cable home gateway, the cable home gateway has a built-in Cable Modem module, TS over IP module, Route module and HLS Server module, wherein:

[0051] The TS over IP module is used to encapsulate the TS stream of the specified frequency point and the specified PID program into an IP stream;

[0052] The HLS Server module slices the TS stream and generates an m3u8 playlist for the terminal to play by adopting a rate-adaptive method;

[0053] Cable Modem module, used to realize modulation and demodulation function;

[0054] Route module, used to realize route selection;

[0055] The video distribution process is:

[0056]Step S100: when the cable home gateway is online, download the electronic program guide from the front-end TFTP server, the electronic program guide is used to describe the program information that can be played through the cable h...

Embodiment 2

[0072] On the basis of Example 1, combined with image 3 As shown, the specific steps for the terminal to send a live broadcast request in step S500 include:

[0073] Step A1: The terminal invokes the play interface, and sends a play (play) request to the cable home gateway. The play request carries a live request parameter, and the live request parameter includes a channel name and a desired play type;

[0074] Step A2: The cable home gateway receives the play request, parses the parameters, and when the expected playback type is Type=1, obtains the PID information from the program list, successfully obtains the information, joins the IGMP multicast, pushes it out from the Eth channel, returns True and the play link, And detect the heartbeat in real time. When the link is disconnected, stop streaming and release the channel; if the acquisition of information fails, return false; if Type=2, obtain the multicast address and PcrPid from the program list, if the acquisition fails...

Embodiment 3

[0078] On the basis of Example 1, in conjunction with the attached Figure 4 As shown, the specific steps for the terminal to send an on-demand request in the step S500 include:

[0079] Step B1: The terminal initiates a request to the streaming front-end for the on-demand program, and the streaming front-end returns the parameters of the corresponding on-demand program, and the parameters include frequency point, program number and modulation method;

[0080] Step B2: After receiving the parameters of the corresponding on-demand programs returned by the streaming front-end, the terminal initiates a setup request to the cable home gateway and carries the parameters;

[0081] Step B3: The cable home gateway receives the setup request and analyzes it, locks the corresponding frequency point and obtains the video stream of the program corresponding to the program number, if the requested frequency point is successfully locked, analyzes the PID information of the program according...

Abstract

The invention discloses a video distribution method based on a cable home gateway, comprising: downloading an electronic program guide from a front-end TFTP server when the cable home gateway is online; downloading a live list from the front-end TFTP server after the cable home gateway is powered on and started; the cable home gateway Obtain and lock the main frequency point from the configuration file, find the video stream corresponding to the program number of the main frequency point, parse the video stream into service group information and save it, and the service group information is the location information where the current home gateway is located; the terminal Establish a network connection with the cable home gateway; the terminal sends a live broadcast request or an on-demand request; the cable home gateway sends a playback video to the terminal. The present invention solves the pain points of multi-user, multi-terminal, mobile, and IP-based, and simultaneously provides high-quality video and Internet services, and improves user stickiness to the product.

Description

technical field [0001] The invention relates to the technical field of gateways, in particular to a video distribution method based on a cable home gateway. Background technique [0002] According to the development trend of consumer electronics products towards intelligence, mobility, and IP, there are more and more types of smart terminals for households, such as mobile phones, PADs, smart TVs, set-top boxes, and other smart home devices. The home gateway is no longer able to meet the needs of video distribution and transmission for different terminals such as mobile phones, PADs, smart TVs, and OTT set-top boxes at the same time. Contents of the invention [0003] The purpose of the present invention is to provide a video distribution method based on a cable home gateway, which is used to solve the problem that the traditional home gateway in the prior art cannot meet the requirements of video distribution and transmission for different terminals at the same time.
