 of music, voices, movies, etc., but also capable of reading a character group, such as information of attributes. This makes it possible to easily read out character groups stored in the disc as well as divert the construction of a disc playback device of a general type to the reading of the character group.
More preferably, the disc playback means is constructed such that the disc playback means receives a request signal generated in response to a key operation of a remote controller from the remote controller, and transmits a portion of a character group to be displayed on a display of the remote controller to the remote controller, the portion corresponding to the request signal, and the reading means further includes remote-controlled communication means for sending the request signal and receiving the portion of the character group in place of the remote controller.
The aforementioned disc playback device of the general type is constructed such that it receives a request signal generated by a key operation from the remote controller, and transmits a character group in response to the request signal. Therefore, by generating the same request signal as generated by the remote controller for the same processing, the character printing device can also obtain the same character group as obtained by the remote controller. That is, in this character printing device, the reading means has the disc playback means and the remote-controlled communication means for transmitting the same request signal as generated by the remote controller and receives the character group, which makes it possible to obtain the character group stored in the disc. It should be noted that by configuring the remote-controlled communication means such that it causes the remote controller to generate a plurality of request signals by a single operation and transmit a combination of a plurality of successive request signals to the disc playback device, it is possible to obtain a plurality of character groups corresponding to the respective request signals by a single operation.
The above and other objects, features, and advantages of the invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. This invention relates to apparatus and methods of forward error correction.
Forward error correction techniques typically are used in digital communication systems (e.g., a system for reading information from a storage medium, such as an optical disk) to increase the rate at which reliable information may be transferred and to reduce the rate at which errors occur. Various errors may occur as data is being read from a storage medium, including data errors and erasures. Many forward error correction techniques use an error correction code to encode the information and to pad the information with redundancy (or check) symbols. Encoded information read
of music, voices, movies, etc. , but also capable of read a fictional character group, such as information of attributes. This makes it potential to easily read out character group stored in the disc equally well as deviate the construction of a disk playback device of a general type to the recitation of the fictional character group. 
 More preferably, the disc playback means is constructed such that the disc playback means meet a request signal generated in response to a key mathematical process of a remote controller from the remote controller, and convey a portion of a character group to be displayed on a display of the remote controller to the outside controller, the portion corresponding to the request signal, and the reading means far admit remote - controlled communication means for sending the request signal and receiving the portion of the character group in place of the remote accountant. 
 The aforementioned disc playback device of the cosmopolitan character is constructed such that it receives a request signal generated by a key process from the remote controller, and transmits a character group in reception to the request signal. Therefore, by generating the same request signal as generated by the remote controller for the like processing, the character printing device can also obtain the same character group as obtained by the distant controller. That is, in this character printing device, the reading means have the disc playback means and the remote - operate communication means for transmitting the same request signal as generated by the outback controller and get the character group, which make it possible to receive the character group store in the disc. It should be note that by configuring the remote - controlled communication means such that it causes the distant controller to beget a plurality of request signals by a single operation and transmit a combination of a battalion of successive request signals to the phonograph record playback device, it is possible to obtain a plurality of character groups corresponding to the respective request signals by a individual operation. 
 The above and other objects, features, and advantages of the invention will become more apparent from the following detailed description taken in junction with the attach to drawings. This invention relates to apparatus and methods of forward error correction. 
 Forward mistake correction techniques typically are used in digital communication organization (for example, a system for reading information from a storage medium, such as an optical disk) to increase the rate at which authentic information may be transferred and to shrink the rate at which errors occur. Various errors may occur as datum is being learn from a storage medium, including data errors and erasures. Many forward error correction techniques practice an erroneousness correction code to encode the information and to pad the information with redundancy (or check) symbols. encode information read
