Problems solved by technology
If the subtitle data and PSIP data respectively include viewing restriction information (i.e., if corresponding viewing restriction information for subtitle data and PSIP data are included in the encoded analog signal at the same time), the video signal included in the analog signal may be distorted
Here, distortion of the video signal may include a time offset between the image and subtitle data
That is, subtitle data may not be arranged in an appropriate area of an image due to a predetermined time delay

A transmission stream transmitting / receiving system is provided. The transmission stream transmitting / receiving system includes a transmission stream transmitting apparatus to transmit a transmission stream including first viewing restriction information and viewing restriction insertion information; and a transmission stream receiving apparatus including a video extractor to extract a digital video signal from the transmission stream, a data processor to extract the viewing restriction insertion information and the first viewing restriction information from the transmission stream, an encoder to encode the digital video signal extracted by the video extractor into an analog video signal; and a controller to control the encoder to allow the first viewing restriction information extracted by the data processor to be included in the analog video signal based on the viewing restriction insertion information extracted by the data processorr.
Description
technical field [0001] The present invention relates to a transmission stream transmission / reception system and its control method, in particular to a transmission stream transmission / reception system and its control method, which includes a transmission device for transmitting transmission streams and a receiver for receiving them means, the transport stream includes predetermined information and video signals. Background technique [0002] Generally, digital broadcast signals include video and audio signals and control information in digital format. [0003] For example, an Advanced Television Systems Committee (ASTC) type digital broadcast signal includes control information in Program and System Information Protocol (PSIP) data. [0004] The control information includes viewing restriction information for indicating ratings of digital broadcast programs, thereby protecting children from viewing yellow digital broadcast program content. [0005] A digital broadcast sign...
