Abstract: In a relay device, a storage section stores data items having order information (e.g. sequence numbers) added thereto, received from a transmitting-end device. A transmission order controller reads out the data items from the storage section such that the data items are transmitted in an order corresponding to information to be notified to a receiving-end device, and transmits the data items. This enables a detecting section of the receiving-end device to detect that a receiver thereof has received the data items the sequence numbers of which are arranged not in an order of 1, 2 and 3 but in an order of 3, 1 and 2, for example, and detect that information corresponding to this order has been transmitted from the relay device. A rearrangement controller rearranges and outputs the data items received by the receiver based on the sequence numbers in an order of the sequence numbers.

Abstract: Audio DIF blocks containing audio data and video DIF blocks containing video data are extracted by an audio/video extracting unit and respectively recorded in separate storage areas of an HDD. System data and audio auxiliary data are extracted by a system data reconstruction unit and thereafter recorded in a system data storage area of the HDD together with frame information generated by a frame information generating unit. The respective data items are recorded in these separate areas, while the audio auxiliary data is recorded together with the system data, and therefore it is easy to rewrite the data during an editing operation.

Abstract: At a transmitting end, information data, which is data to be transmitted, is copied via a number of wireless transmission paths and then encoded. Each piece of data is then subjected to a respective different pattern of puncturing process and transmitted to a receiving end via a respective wireless transmission path. At the receiving end, dummy data is embedded into the punctured data and decoded. The puncture patterns at the transmitting end for the respective different wireless transmission paths are prepared such that they are different from each other. In particular, the bits to be removed are preferably different from each other between the different puncture patters. At the receiving end, if the decoding of the data for any wireless transmission path has failed, the data obtained from other wireless transmission paths are combined and decoded. In this way, the probability of a decoding failure occurring can be lowered.

Abstract: At the time of carrying out a DHO, a DHO execution unit encodes data to be transmitted and interleaves it, followed by dividing it into segment data and sending out from respective transmission paths. When receiving data, the unit receives pieces of segment data from the respective transmission paths, combines them together, de-interleaves them and receives data by decoding it. When dividing into segment data, it allocates segment data with larger amount of data to a transmission path with a high transmission quality, and that with smaller amount of data to a transmission path with a low transmission quality, in accordance with the transmission quality.
