Method and system for transmitting stock information through one-way digital TV network

Abstract

The invention relates to a method for transmitting securities information by using a unidirectional network of a digital TV and a system thereof, in particular to data transmission of the securities information in a digital TV network, which belongs to a field of data communication of the securities information. The method includes the processes: a front terminal recodes the received transaction data; then, private data is encapsulated and packed into a TS and after encapsulated, the TS is transmitted to a terminal through a network; after the terminal receives the data, decapsulation and decoding are carried out by the terminal for the received data and then the obtained data is put into use. The system consists of the front terminal and the terminal; wherein, the front terminal consists of a unit for encoding the securities information and a unit for transmitting the securities information while the terminal consists of a unit for receiving the securities information. In the method for transmitting the securities information by using the unidirectional network of the digital TV and the system thereof, on the premise that the saving of bandwidth is taken into consideration, the transaction data is recoded in the front terminal and then the private data is encapsulated and then packed into the TS; besides, the method for transmitting the securities information has the advantages of small occupied bandwidth and favorable receiving effect.

Description

technical field [0001] The invention relates to the field of securities information data communication, in particular to the securities information data transmission of digital television network. Background technique [0002] Digital TV has flourished worldwide. The transmission ways of digital TV can be divided into three types: digital satellite TV, digital cable TV and digital wireless (terrestrial) broadcast TV. The reception of terrestrial digital TV has the following forms like cable digital TV: (1) household digital TV receiver; (2) digital TV set-top box + household analog digital TV receiver; (3) digital TV receiving card + multimedia computer. Different from cable digital TV, terrestrial digital TV puts more emphasis on the mobile reception function. At present, vehicle-mounted mobile digital TV has appeared, including cars, trains, subways, etc., which will be the unique territory of vehicle-mounted mobile digital TV. Mobile digital TV receivers will become eme...

Problems solved by technology

At this time, traditional ways such as Internet transmission and satellite transmission can be used to receive real-time data in the market, but the terminals of these two methods do not have good civilian use or mobility. GPRS is used for mobile services in mobile phones and PDAs. , because the receiving method is point-to-point and occupies bandwidth, it consumes a lot of resources, and it is usually difficult to obtain ideal receiving effects
