Network television playing method and system under cloud environment

Abstract

The invention discloses a network television playing method and system under the cloud environment. The network television playing system comprises a client-side, a server-side and a virtual machine configured at the server-side. Connection between network television software in the virtual machine and an external multimedia source is established and network television data streams to be decoded are received from the network; a network television interception module in the virtual machine intercepts the television data streams, and the network television data streams to be decoded are sent to the client-side through a multimedia channel which is added in the server-side; the client-side receives and decodes the network television data streams to be decoded through a multimedia channel added in the client-side and decoded information is displayed. According to the network television playing method and system, the multimedia channels used for network television data stream transmission are added in the server-side and the client-side respectively, and therefore decoding and playing, on the client-side, of the network television data streams are realized. On the premise that usability and reliability are guaranteed, the requirements for network television watching of users can be met to a great 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
