Abstract

The invention discloses a method for realizing media distribution and positioning by sub-chip storage and a streaming media system thereof, a central node inputs time tag information in original code streams at definite time; the code streams with the same channel identifiers and the time tag information are named and constitute sub-chip files for carrying out the sub-chip storage; the sub-chip files are distributed to various edge nodes from the central node; the node which a user belongs to is positioned to the sub-chip file during the sub-chip storage according to a signaling; and a plurality of sub-chip files is smoothly switched by using the time tag information. As the time tag is input in the direct broadcast code streams at definite time and the sub-chip files are named by combining a channel identifier, the invention realizes the uniform storage of the sub-chip files during the creation of a direct broadcast channel; additionally, the invention adopts the seamless splicing of the adjacent sub-chip files of the time tag, thereby achieving the uniform storage of time-shifted television businesses and television program on-demand businesses, greatly reducing the requirements of the whole system on storage space and storage resources and improving the reliability and the stability of the service of the streaming media system.

Description

technical field [0001] The invention relates to the control method and system field of streaming media in multimedia communication, and in particular to a method for realizing media distribution and positioning through segmented storage and a streaming media system thereof. Background technique [0002] Personalized interactive TV or interactive network TV IPTV (Interactive Personality TV, hereinafter referred to as IPTV), is a broadband cable TV network, which integrates Internet, multimedia, communication and other technologies, to provide users with digital TV Brand-new technologies for a variety of interactive services, including It can well adapt to the rapid development trend of today's network and make full and effective use of various network resources. [0003] IPTV is not only different from traditional analog cable TV, but also different from classic digital TV. Because both traditional analog TV and classic digital TV have the characteristics of frequency divis...
