Embodiment Construction

[0021] see figure 2 , is a schematic diagram of the first embodiment of the digital television network system of the present invention. The digital TV network system 10 includes: a multiplexer 1 , a digital TV program source 2 , an EPG system 3 , a transmission network 4 , a STB 5 and a digital TV 6 . Wherein, the multiplexer 1 includes: a transmission demultiplexing unit 12 , a program adjustment module 16 and a transmission multiplexing unit 18 . The operation process of the digital television network system 10 is as follows:

[0022] The digital TV program transport stream TS provided by the digital TV program source 2 and the EPG information transport stream TSn generated by the EPG system 3 are transmitted to the multiplexer 1 . The transmission demultiplexing unit 12 of the multiplexer 1 demultiplexes TS and TSn to obtain program and EPG information. The program is transmitted to the program adjustment module 16, the EPG information is transmitted to the program adju...

Abstract

The provided multiplexer comprises: a transmission de-multiplex unit to de-multiplex data flow of digital TV and electric menus for guide information, at least one menu adjust module to adjust menu sound volume, and a transmission multiplex unit to multiplex and output adjusted menus.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a multiplexer, a digital television network system and a volume adjustment method thereof. Background technique [0002] see figure 1 , is a schematic diagram of a digital television network system in the prior art. The digital TV network system 80 includes: a multiplexer 81, a digital TV program source 82, an electronic program guide (EPG, Electronic Program Guide) system 83, a transmission network 84, a digital TV terminal set-top box (STB, Set Top Box) 85 and a digital TV 86. The digital TV program is collected, processed and encoded to form a digital TV program source 82, and transmitted to the multiplexer 81 in the form of Transport Stream (TS, Transport Stream), such as MPEG-2 or MPEG-4 TS. The EPG system 83 also transmits the EPG information to the multiplexer 81 in the form of TS. The multiplexer 81 multiplexes the multiple TSs and sends them out. After pa...
