A recording/editing apparatus is provided with an operation inputting device. A user uses this operation inputting device to input record-reservation information, a delete condition to delete record contents from a storage medium, or the like. Moreover, the recording/editing apparatus can access a server via a communicating device and a network. The server accumulates and saves program-information provided from other users, and supplies information corresponding to the delete condition to the recording/editing apparatus, in accordance with a request of the recording/editing apparatus. The recording/editing apparatus judges whether or not the delete condition is satisfied on the basis of the supplied information, and deletes the record contents from the storage medium if the delete condition is satisfied.

Block forming method and apparatus of a digital bit stream, in which such an inconvenience that in spite of the fact that additional data regarding a partial packet to be located at the end of a main data portion exists in an additional data portion, the partial packet becomes a block in which no byte actually exists can be eliminated. When a space area smaller than one packet occurs in the end portion of the main data portion of the data block, partial data of the next packet is stored in the space area, the additional data of the next packet is stored in the additional data portion as additional data of one partial packet and the remaining data of the partial data of the next packet is stored in a start portion of the main data portion of a next data block. When the space area does not occur in the end portion of the main data portion, additional data invalid information showing that the additional data of one partial packet is invalid is stored in a portion other than the main data portion in the data block.
