Abstract

The invention discloses a one-way terminal barrage method based on digital television conditional access. By utilizing mobile phone short messages, the method supports a digital television authorized user to use a one-way terminal device, and a user broadcast function of a CA system is utilized such that the terminal CA system receives corresponding EMM data and analyzes the data to obtain barrage content and a corresponding logic channel number. A digital television terminal system displays the barrage content in a rolling manner at an uppermost layer of the OSD if the system judges that the program watched by the user currently and the program corresponding to the barrage content are the same, otherwise does not process the barrage content. The method of the invention enables the user to participate in and see the comment content of live digital television. The user could directly participate in the comment of the real-time live program by using the short messages on the basis of a most common one-way digital television terminal, so that the entertaining performance of the program and the participation sense of the user are improved.
