Embodiment approach

[0196] As an optional implementation, the device may also include:

[0197] The second obtaining module is used to obtain the channel identifier sub-sets corresponding to the M video gateways;

[0198] A deduplication module, configured to perform a union operation based on the M subsets of channel identifiers to obtain the set of channel identifiers, wherein any two channel identifiers in the set of channel identifiers are different from each other.

[0199] Among them, after the video gateway is powered on, it first searches for digital TV channels that can be received by the device, and then uploads the resource capability and channel list of the device to the distributed network TV live broadcast server. The distributed network TV live broadcast server will perform "deduplication" processing on the channel lists transmitted by M video gateways, that is, remove channels with duplicate names, and finally form a set of channel identifiers.

Abstract

The invention provides a distributed network television live broadcast method, a device, a video gateway and a system. The method comprises the steps that the resource information and channel identifier collection of M video gateways is acquired; a broadcast request which carries the configuration information of a broadcast terminal and a broadcast command for a target channel identifier and is sent by the broadcast terminal is received; the broadcast request is responded; according to the resource information, a video gateway is selected from M video gateways and is used as a target video gateway which provides a video content transmission service for the broadcast terminal; and a video content pushing request which carries the configuration information of the broadcast terminal is pushed to the target video gateway, so that the target video gateway pushes a video content to the broadcast terminal. According to the technical scheme of the invention, the operation cost of a network live broadcast television system is reduced.

Description

technical field [0001] The invention relates to the technical field of media transmission, in particular to a distributed network TV live broadcast method, device, video gateway and system. Background technique [0002] At present, there are three main ways to realize the network live broadcast TV system used on a large scale. The first one is to convert the live program collection into Internet IP video stream by the live program collection server, and then through the content distribution network composed of streaming media distribution server clusters ( CDN) to the receiving terminal. The second is IP multicast-based live TV generally adopted by telecom operators. The source of live broadcast programs passes through several network devices (including routers, The broadcast copy function is distributed to the corresponding receiving terminal. The third is the live TV system implemented by P2P peer-to-peer network technology. In the P2P live broadcast system, the live pro...
