Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] The present invention mainly recognizes a plurality of logical data streams on the DVB-T2 system; then establishes a corresponding java virtual machine for each logical data stream based on the multiple logical data streams; runs each corresponding java virtual machine through the corresponding java virtual machine A logical data flow; displaying parameter information corresponding to each logical data flow based on the corresponding java virtual machine. An...

Abstract

The invention discloses a method and system for extracting DVB-T2 code steam information through a virtual machine. The method includes the steps that a plurality of logic data flows on a DVB-T2 system are identified; a corresponding java virtual machine is built for each logic data flow is built based on the logic data flows; each corresponding logic data flow is operated through the corresponding java virtual machine; the parameter information corresponding to each logic data flow is displayed based on the corresponding java virtual machine. According to the method and system, the logic data flows on the DVB-T2 system are identified through a receiving terminal, the corresponding java virtual machine is built for each logic data flow, each logic data flow is operated accordingly, the content or parameters in the logic data flows can be fed back to an operating user, the operating user can know related information in the logic data flows conveniently so as to process the logic data flows, and thus control over the logic data flows is achieved.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method and a system for extracting DVB-T2 stream information through a virtual machine. Background technique [0002] DVB-T2 is the second-generation European digital terrestrial television broadcasting transmission standard. The maximum TS stream transmission rate supported within the 8MHz spectrum bandwidth is about 50.1Mbit / s (if including the empty packets that may be removed, the maximum TS stream transmission rate can reach 100Mbit / s). At present, the European DVB standard has entered the second-generation promulgation period successively, among which the DVB-S2 standard was announced in 2006, and the DVB-T2 standard was announced in June 2008. [0003] In order to squeeze out more capacity in terrestrial TV channels for HDTV services, the European Digital Video Broadcasting Organization (DVB) has formulated the second-generation terrestrial digital TV broadc...
