CPE equipment supporting 4K or 8K television live broadcast and application system of CPE equipment

Abstract

The invention relates to CPE equipment supporting 4K or 8K television live broadcast and an application system thereof. The system comprises a processor with a routing function, the processor is connected with a communication module, a WiFi module in communication connection with a mobile terminal, a network module in communication connection with a fixed terminal and capable of accessing a broadband network, and a direct broadcast satellite code stream conversion module. The direct broadcast satellite code stream conversion module comprises a satellite receiving antenna, a multi-channel Tunermodule and a descrambling module with a descrambling chip which are connected in sequence, the direct broadcast satellite code stream conversion module sends descrambled video data to the processor,and video distribution is carried out on terminal users through the WiFi module or the network module. The CPE is applied to an application system in which a terminal is connected with a network communication base station and receives satellite television signals. The CPE integrates all the modules into a whole, so that network communication signals and 4K or 8K television live broadcast signals can operate independently, and the problem that the television live broadcast signals need to occupy network channels to be transmitted when traditional CPE is used is solved.

Description

technical field [0001] The invention relates to the technical field of video processing and communication, in particular to a CPE device supporting 4K and 8K TV live broadcast and an application system thereof. Background technique [0002] CPE, the English full name is Customer Premise Equipment, literal translation: Customer Premise Equipment; it is actually a mobile signal access device that receives mobile signals and forwards them with wireless WIFI signals. It is also a kind of high-speed 4G or 5G signals. WiFi signal equipment can support more mobile terminals to surf the Internet at the same time, and it can save the cost of laying wired networks after being widely used in rural areas, towns, hospitals, units, factories, communities and other wireless network access. [0003] At the same time, after the advent of the communication 5G era, enhanced bandwidth (EMMB) is an important application scenario of 5G. According to national standards, a single-channel 8K live TV...

Problems solved by technology

[0003] At the same time, after the advent of the communication 5G era, enhanced bandwidth (EMMB) is an important application scenario of 5G. According to national standards, a single-channel 8K live TV signal reaches 150MBps, and a 4K signal also reaches 36MBps. For traditional CPE equipment, like image 3 As shown in , the traditional CPE equipment is to enter the 4K and 8K TV signals into the operator's cloud resource platform through the backbone network, become part of its cloud resources, and then transmit them to the terminal equipment after injection, transcoding, slicing and other technical processing. Mobile devices such as mobile phones and PADs, and fixed-terminal receiving devices such as set-top boxes and TVs can watch live content through the operator’s CDN, but this method will consume a lot of bandwidth resources of the operator’s backbone network and wireless distribution network. Precious 5G frequency band resources. After the launch of 8K TV programs and the popularization of 4K TV programs, there will be more than 100 sets of live TV programs nationwide, with a total bandwidth of more than 1G. Using the above technical implementation plans will consume a lot of bandwidth resources of operators. The quality of video transmission is affected, resulting in the problem of unsmooth signal transmission
