Double-mode television (TV) capable of receiving ground TV signals and network TV signals

Abstract

The invention relates to a double-mode television (TV) capable of receiving ground TV signals and network TV signals; the double-mode TV comprises a user datagram protocol (UDP) unpacking module, an internet protocol (IP) unpacking module, a lower frequency conversion processing module, a channel data decoding module, a demultiplexing unpacking module and a switching control module, wherein the UDP unpacking module and the IP unpacking module are sequentially connected and are used for processing the received network TV signals so as to obtain transport stream (TS); the lower frequency conversion processing module and the channel data decoding module are sequentially connected and are used for processing the received ground TV signals so as to obtain TS; and the demultiplexing unpacking module is used for confirming to receive the TS coming from the network TV signals or the ground TV signals under the control of the switching control module so as to carry out demultiplexing and TS unpacking processing. After the double-mode TV is adopted, the functions of a receiving device can be expanded, and the double-mode TV is compatible in receiving and playing of the ground TV signals and the network TV signals.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a dual-mode television set for receiving terrestrial television signals and network television signals. Background technique [0002] Digital TV gradually replaces the original analog TV because it carries many programs and the program quality is good. The current digital TV can be divided into terrestrial TV, satellite TV, terrestrial TV and Internet TV according to the transmission signal. Generally, a fixed type of transmitter corresponds to a fixed type of receiver, for example, a terrestrial TV receiver such as a terrestrial TV The set-top box only receives signals transmitted by terrestrial TV transmitters, but not signals transmitted by other types of receivers. Similarly, the types of TV receivers are relatively fixed, and can only receive one of the above-mentioned multiple types of TV signals. [0003] However, because the types of terrestrial TV, satellite TV, terres...

The current digital TV can be divided into terrestrial TV, satellite TV, terrestrial TV and Internet TV according to the transmission signal. Generally, a fixed type of transmitter corresponds to a fixed type of receiver, for example, a terrestrial TV receiver such as a terrestrial TV The set-top box only receives signals transmitted by terrestrial TV transmitters, but cannot receive signals transmitted by other types of receivers. Similarly, the types of TV receivers are relatively fixed and can only receive one of the above-mentioned types of TV signals

[0003] However, because the types of terrestrial TV, satellite TV, terrestrial TV, and Internet TV are only in the channel transmission mode, but in the multiplexing of code streams, the packaging format of transport streams, etc., they are the same, so if you have to face When there are multiple types of transmitters, users need to replace different types of TVs that receive TV signals in time, which is a waste of resources, especially for TV viewers who often move in different regions, when they need to use multiple different TVs This waste is even more pronounced when receivers are adapted to different types of transmitters in various regions
