User request processing system and method for electronic program guide system

Abstract

The invention provides a user request processing system and a user request processing method for an electronic program guide (EPG) system. The user request processing system comprises an HTTP request processor, an HTML page register and an application interface module, wherein the HTTP request processor receives an HTTP request from a client and feeds back an HTML page generated according to the client request to the client; the HTML page register caches and manages the generated HTML page in a page cache region and searches a page requested by the client in the page cache region according to the received HTTP request; and the application interface module forwards the HTTP request needing to be processed to an associated EPG conventional service logic module for processing and writes the HTML page generated by the service logic module into the page cache region. The system of the invention can be in seamless joint with a service logic application program in the conventional EPG system, fully uses data and an HTTP content catching mechanism, increases multiplexing efficiency of acquired data or generated dynamic and static HTML pages, and improves the performance of the conventional EPG system by 5 to 10 times.

Description

technical field [0001] The invention relates to digital TV and interactive network TV system, in particular to a user request processing system and processing method for electronic program guide system. Background technique [0002] EPG is the English abbreviation of Electronic Program Guide. In modern digital TV and IPTV systems, the indexing and navigation of various services are realized through the EPG system. EPG is actually a portal subsystem of a digital TV or IPTV system, and its functions and performance have a great impact on the service experience of end users. [0003] Using the electronic menu provided by EPG, end users can choose their favorite multicast channels, order their favorite video programs, query various online information provided by IPTV or related systems, and purchase various additional value-added services. [0004] In the existing IPTV system, the EPG server adopts a Web-based architecture. The user set-top box (STB) interacts with the EPG se...

Problems solved by technology

[0005] A common problem of the existing EPG system is poor system performance. Taking the above system as an example, the Tomcat-based JSP / Java application program (or in other words, the Web presentation layer) in the EPG server has a performance bottleneck when processing user requests

Relevant tests and data show that even if there is no complex operation of the back-end business logic layer and database layer, this kind of Web presentation layer can only handle 600-800 user requests at most within 2-3 seconds, which is difficult to meet the needs of telecom operators IPTV. Network customer needs

[0006] Moreover, in the existing EPG system, searching for data can only fully retrieve the database, so the operation of the database is inefficient and slow, which further limits the response speed and capacity of the system

Considering the above factors, the overall performance of the existing EPG system is low, and only 100-200 user requests can be completed within 2-3 seconds

[0007] In addition, after previous development, the existing EPG system has accumulated a large number of business logic applications. If a high-performance system is redeveloped from scratch, the business functions of the original system will inevitably be unusable, resulting in waste of resources and overall development. Significant increase in cycle time and development costs

[0008] Therefore, it is necessary to design a system and method to overcome the defects of poor performance of the existing EPG system and improve the performance of the EPG system as a whole under the premise of retaining the business functions of the existing system
