    摘要： A television signal receiving apparatus and method is provided having channel decode means for receiving a signal with a video signal, a sound signal, a data signal, and additional data multiplexed to perform tuning, demodulation, and error correction on the received signal and a demultiplexor for separating the multiplexed signal to output coded data of each of the video signal, the sound signal, and the data signal and for extracting service information as one of additional data. A storage device is provided for storing the service information extracted from the demultiplexor, together with a write controller for controlling writing into the storage device, and a read controller for controlling reading of the storage device according to a user command entered by a user. A source decoder is also provided for decoding the coded data outputted from the demultiplexor using the information outputted from said storage device to output the video signal, the sound signal, and the data signal. The storage device records the service information supplied from the demultiplexor, and the read controller performs control such that necessary data are read from the storage device as required by the user, thereby enhancing the speed of processing associated with the service information to provide a quick response to the user requirement. Also, the write controller can control storage such that only necessary information for the next processing operation is stored, thereby reducing the size of the storage device which is necessary.

    摘要： An arrangement to automatically change between a scrambled digital data output and descrambled digital data output of a receiver by inserting a control signal conforming to a program provider's policy into a transmission signal. In a receiving side, a descrambler descrambles a channel-decoded signal, a demultiplexer demultiplexes the multiplexed signal from the descrambler into encoded video and audio data for output to a source decoder, and extracts the control information inserted in the transmitting side for output to a switch or CPU. The CPU decrypts a control signal from the control information extracted by the demultiplexer to determine whether the scrambled digital signal or descrambled digital signal is appropriate for output, and outputs a changeover control signal depending on the result of decryption. A switch selects the output of a scrambled digital signal from a stage prior to the descrambler, or a descrambled digital signal from a stage subsequent to the descrambler, depending on the changeover control signal from the CPU. Thereby, a scrambled digital signal output or descrambled digital signal output can automatically be changed over depending on a program provider's policy.

    摘要： In a digital broadcasting receiver, an identification information of the image or audio signal detected from the received digital information, and an identification information stored in an identification information memory means are compared one after another. The image/audio mute means is controlled not to output a disordered image/audio signal on the basis of the comparison result. On the basis of the comparison result, the viewer is informed by the identification information output means that resolution/quality of the received image/audio signal is changed. The identification information showing the image resolution and audio quality is inserted into digital information, and the digital information with the identification information is transmitted in a digital broadcasting transmitter.
