A method and system for playing network television in a cloud environment

Abstract

The invention discloses a method and system for playing Internet TV in a cloud environment. The system includes a client, a server, and a virtual machine configured on the server. The Internet TV software in the virtual machine establishes a connection with an external media source, and accesses the network from the network. Receive the IPTV data stream to be decoded in the virtual machine; the IPTV interception module in the virtual machine intercepts the IPTV data stream, and sends the IPTV data stream to be decoded to the client through the media channel added inside the server; the client adds The internal media channel receives and decodes the IPTV data stream to be decoded, and displays the decoded information. The present invention realizes the decoding and playing of the Internet TV data stream at the client end by respectively adding media channels for the transmission of the Internet TV data stream at the server end and the client end. On the premise of ensuring the usability and reliability, the user's demand for watching Internet TV can be satisfied to a large extent.

Description

technical field [0001] The present invention relates to the fields of cloud computing, virtualization and desktop virtualization, and in particular to a method and system for playing network television in a cloud environment. Background technique [0002] When the concept of virtualization first emerged in the 1970s, mainframe computers have been running multiple instances of an operating system simultaneously, each independently of the other. The main purpose of virtualization is to simplify the IT infrastructure. It simplifies access to resources and resource management, reducing the coupling between consumers and resources. The virtual machine is an abstraction and simulation of the real computing environment. The virtual machine monitor VMM needs to allocate a set of data structures for each virtual machine to manage their state, including the full set of registers of the virtual processor, the usage of physical memory and the virtual device. status etc. [0003] Unde...

AI Technical Summary

Problems solved by technology

[0004] In the existing desktop virtualization technology, after the user logs in to the remote desktop through the remote display protocol client, the user runs the network TV software to play the video (such as PPTV, PPS, QQlive, etc.), and the network TV software displays the video on the server side, and the Screen capture of the entire virtual machine desktop, and subsequent compression and encoding are transmitted to the remote display protocol client. Due to the high frequency of video screen changes, frequent encoding and transmission of pictures is required, which not only increases the burden on the server-side CPU, but also affects performance. At the same time, high network bandwidth is required, which affects the user experience when using

[0005] Due to the above-mentioned shortcomings, each remote display protocol adopts some methods to improve this problem, such as not transmitting the whole screen, only transmitting the changing area pictures, or using a lossy compression algorithm to compress and transmit the rapidly changing and relatively large pictures , but even after using the above methods to optimize, it still cannot effectively solve the user experience problem of Internet TV
