Embodiment

[0020] This example adopts the solution of the present invention to control the use of the cable digital TV FTA set-top box.

[0021] Firstly, the control information of the set-top box is imported into the database of the data management system, wherein the database adopts a SQL-SERVER database, and the control information of the set-top box includes the set-top box machine number, control identification and expiration (end) date, and then the data management system judges all data in the database. Whether the expiration date in the control information of the set-top box is less than the current time, if so, delete the control information of the set-top box, if not, retain and extract the control information of the set-top box and generate a data stream for all the extracted control information of the set-top box according to the private data format, Then the data stream is multiplexed to all frequency points for transmission, the set-top box system receives and filters out th...

Abstract

The invention relates to a technology of a cable digital TV. The invention solves the problem that the method for controlling the FTA set-top box of the cable digital TV to watch programs does not exist at present. The invention provides a using control method of the FTA set-top box of the cable digital TV. The technical scheme comprises the following steps: firstly, the control information of the set-top box is led into the database of a data management system; the data management system causes all the control information of the set-top box in the database to generate a data flow according to a proprietary data format; the data stream is reused on all frequency points for sending; a set-top box system receives and filters out the data flow analysis and then analyzes and judges whether the data flow includes the number of the set-top box, if else, the set-top box system prompts not to obtain authorization; if yes, the set-top box system judges whether the set-top box is allowed to be watched according to the analyzed set-top box control indication, if yes, the set-top box can play; if else, the set-top box system prompts not to obtain authorization. The method has the advantages that the method effectively controls the watching permission of users and is suitable for the FTA set-top box of the cable digital TV.

Description

technical field [0001] The invention relates to cable digital TV technology, in particular to cable digital TV set-top box management technology. Background technique [0002] The cable digital TV FTA set-top box is a digital TV set-top box that is completely free to watch programs without encryption. At present, many operators provide such services, but the relationship between various operators is a relationship of competition. Many users may buy set-top boxes from other operators to watch programs on another operator's cable TV network, which has caused relatively large economic losses to the cable TV operator, but there is no effective technical means at present To control the cable digital TV FTA set-top box to watch the cable TV broadcast by other operators. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for controlling the use of a cable digital TV FTA set-top box in order to overcome the lack ...
