Embodiment Construction

[0037]The core of the invention is to build a system for VOD playing TV media data in the current broadband Internet, so that customers can actively control the playing time and playing mode of TV. First of all, we use the transcoding server to transcode the existing real-time TV programs to reduce the bit rate, so as to improve the quality of media playback as much as possible under the condition of limited bandwidth; then provide specific playback and operation services to customers through the media server, The TV media data of the service is requested by the data receiving storage entity from the transcoding server, received and stored locally. The structural framework of the entire system is roughly shown in Figure 1, and each entity and function in Figure 1 will be described separately below.

[0038] TVOD transcoding server: This module mainly includes three parts: TV media request processing, transcoding function realization and data distribution. The TV media request...

Abstract

In internet, this invention uses the code-converting server (CS) real time to code-convert the received directly TV media (TM) data, then distributes the code-converted TM data toward all cell media server (CMS). CMS stores these data and offers the TM program ordering service and the real time (RT) directly playing service. These two services can be switched seamlessly. The transferring and service of RT TM operation is realized in Internet and its service quality can be ensured. This device consists of CS, the data receiving / storing entity and media servers. Here, the data receiving entity is the data front end of CMS. Both reside on the same physical server and connect to CS via Internet to execute RT transferring protocol.

Description

technical field [0001] The invention relates to the field of computer multimedia technology, in particular to a method for realizing a streaming media server supporting real-time transcoding, multiple playing modes and operations, and a method for transmitting, storing and streaming reading of streaming media data. Background technique [0002] With the large-scale increase of global broadband users, the multimedia on demand service represented by Video On Demand (VOD) has always been the dream of the public, film and television companies and network service providers. The development of multimedia services such as video on demand on the Internet The need is becoming more and more apparent. Because of its interactivity and immediacy, video multimedia on demand is rapidly becoming an important application of the Internet. [0003] IP TV, also called IPTV, uses the infrastructure of broadband IP network, uses home TV or computer as the main terminal electrical appliance, tran...
