The invention relates to a multipicture comprehensive video navigation system which comprises a live telecast stream system, a program stream transmission system and a multipicture integrative management platform, wherein the live telecast stream system comprises an AV signal input end as well as a coder, a multiplexer and a modulator which are sequentially connected; the program stream transmission system comprises a file server, a stream media broadcast server and a multipicture video post which are sequentially connected; the multipicture integrative management platform provides a management command for the program stream transmission system; the live telecast stream system can respectively transmit live telecast streams to the program stream transmission system and the multiplexer / modulator through ASI ports; the program stream transmission system can transmit program streams to the multiplexer / modulator; and the multiplexer / modulator transmits the received program streams to a user through an HFC network. Besides the functions of navigating and managing integrated services, the system also has extended functions of managing front-end resources, controlling distribution mechanisms, processing and editing interfaces, and the like, realizes the unification and the standardization of a management system and has simple scheme and good expansibility.
Description
technical field [0001] The invention relates to a video navigation system, in particular to a multi-picture integrated video navigation system. Background technique [0002] With the rapid development of digital TV and IPTV (Interactive Personality TV: personalized interactive TV) market, digital media resources are increasingly prosperous, and operators provide hundreds of sets of digital TV programs, including digital TV, video dramas on demand, and massive data video programs , online games and many other channels of business content. The increase of programs has greatly enriched the content of viewing options for users, but at the same time, it has also caused inconvenient program selection, a large number of channel switching operations, and key highlights are not highlighted. It affects the user experience, and also affects the broadcasting effect of various programs. There is no good choice link between good programs and demanders. How to allow users to quickly, int...
