Multifunctional television capable of receiving wired television signals and network television signals

Abstract

The invention relates to a multifunctional television capable of receiving wired television signals and network television signals. The multifunctional television comprises a UDP (User Datagram Protocol) unpacking module, an IP (Internet Protocol) unpacking module, an ASI (Asynchronous Serial Interface) processing module, a timer recovery and serial-parallel conversion module, a synchronous character deletion module, a 8B / 10B decoding module, a demultiplexing and unpacking module and a conversion control module, wherein the UDP unpacking module and the IP unpacking module are sequentially connected and used for processing received network television signals so as to obtain a TS (Transmission Stream); the ASI processing module, the timer recovery and parallel-serial conversion module, the synchronous character deletion module and the 8B / 10B decoding module are sequentially connected and used for processing received wired television signals so as to obtain a TS; and the demultiplexing and unpacking module is used for demultiplexing and unpacking the TS from the network television signals and the TS from the wired television signals under the control of the conversion control module. Through the invention, the functions of a receiving device can be expanded, and the functions of receiving and playing the wired television signals and the network television signals are combined.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a multi-functional television set for receiving cable 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 cable 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 cable TV, satellite TV, terrestrial TV, a...

The current digital TV can be divided into cable 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 cable TV, satellite TV, terrestrial TV, and Internet TV are only in the channel transmission mode, but are the same in the multiplexing of code streams, the packaging format of transport streams, etc., 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
