Video signal recording apparatus, video signal reproducing apparatus and video signal recording and reproducing apparatus
View Patent ↗An information signal is received, which includes a main information content signal carrying the contents of the information, a CM portion signal carrying commercial messages (CM) and an information mode discriminating signal used for discriminating information modes of the main information content signal and the CM signal from each other according to the contents. A video signal is encoded per plurality of several video frames, the video signal including the main information content signal and the CM portion signal. The encoded video signal is recorded in a storage medium. The video signal is reproduced, during the recording, from the storage medium while the CM portion signal is skipped. The received main information content signal and CM portion signal are recorded in the storage medium. The information mode discriminating signal is recorded in the storage medium or another temporary storage medium. At least the information mode discriminating signal is retrieved from the storage medium or the temporary storage medium. Locations of the recorded CM portion signal in the storage medium is detected based on information mode corresponding to the CM portion signal among a plurality of information modes discriminated by means of the information mode discriminating signal. The main information content signal is reproduced from the storage medium while skipping the CM portion signal based on recorded positions of the video signal encoded per plurality of video frames corresponding to the detected locations of the recorded CM portion signal.
1. An apparatus for reproducing a TV signal comprising:
a reproducer to reproduce the TV signal from a storage medium having a bitstream recording area and a management recording area, stored in the bitstream recording area being digital data of a TV signal carrying at least one TV program signal and one CM portion signal carrying commercial message, and stored in the management recording area being management data, having data on locations of the CM portion signal, indicating whether the digital data is the TV program or the commercial message;
a instructor to instruct the reproducer to reproduce the TV signal at a given reproduction speed; and
a controller to control the reproducer so that only the TV program is reproduced based on the data on locations of the CM portion signal when the reproduction speed is equal or lower than a reference speed, whereas both of the TV program and the commercial message are reproduced when the reproduction speed is higher than the reference speed.

a skip button for use in skipping the reproduction of the TV signal for a given period; and
a controller to control the reproducer to skip the commercial message and reproduce the TV program based on the data on locations of the CM portion signal when the skip button is depressed,
wherein the controller controls the reproducer to skip the commercial message and reproduce the TV program that follows the commercial message even if current data to be reproduced is the commercial message after the given period elapses.
4. An apparatus for reproducing a TV signal comprising:
a reproducer to reproduce the TV signal from a storage medium having a bitstream recording area and a management recording area, stored in the bitstream recording area being digital data of a TV signal carrying at least one TV program signal and one CM portion signal carrying commercial message, and stored in the management recording area being management data, having data on locations of the CM portion signal, indicating whether the digital data is the TV program or the commercial message;
a skip button for use in skipping the reproduction of the TV signal for a given period; and
a controller to control the reproducer to skip the commercial message and reproduce the TV program based on the data on locations of the CM portion signal when the skip button is depressed,
wherein the controller controls the reproducer to skip the commercial message and reproduce the TV program that follows the commercial message after the given period elapses even if the stored commercial message is shorter than the given period.
5. A method of reproducing a TV signal comprising the steps of:
reproducing the TV signal at a given reproduction speed from a storage medium having a bitstream recording area and a management recording area, stored in the bitstream recording area being digital data of a TV signal carrying at least one TV program signal and one CM portion signal carrying commercial message, and stored in the management recording area being management data, having data on locations of the CM portion signal, indicating whether the digital data is the TV program or the commercial message; and
reproducing only the TV program based on the data on locations of the Cm portion signal when the reproduction speed is equal to or lower than a reference speed, whereas reproducing both of the TV program and the commercial message when the reproduction speed is higher than the reference speed.
6. A method of reproducing a TV signal comprising the steps of:
reproducing the TV signal at a given reproduction speed from a storage medium having a bitstream recording area and a management recording area, stored in the bitstream recording area being digital data of a TV signal carrying at least one TV program signal and one CM portion signal carrying commercial message, and stored in the management recording area being management data, having data on locations of the CM portion signal, indicating whether the digital data is the TV program or the commercial message;
skipping the commercial message for a given period; and
reproducing the TV program based on the data on locations of the CM portion signal when the commercial message is skipped,
wherein the TV program that follows the commercial message is reproduced after the given period elapses even if the stored commercial message is longer than the given period.
