Abstract:
1. A transmission apparatus, comprising: a processor operable as: a data transmission unit to cause a transmitter to transmit content data through a first transmission path to an external apparatus, and an information transmission unit to cause the transmitter to transmit processing information used to perform processing in synchronization with the content data through a second transmission path to the external apparatus, wherein the second transmission path corresponds to a bidirectional communication path including a certain line of the first transmission path, the bidirectional communication path corresponds to a pair of differential transmission paths, and at least one of the pair of differential transmission paths has a function of transmitting a connection state of the external apparatus using a direct current bias potential, first index information is added to the processing information of each unit of processing transmitted from the information transmission unit such that processing associated with a respective piece of first index information corresponding to the processing information of a specific unit of processing is carried out by the external apparatus at a time at which the external apparatus performs the processing of a particular piece of the content data that is synchronized with the specific unit of processing, and second index information is added to the content data currently being transmitted from the data transmission unit which represents the first index information corresponding to the content data that was previously transmitted from the data transmission unit or that is to be subsequently transmitted from the data transmission unit and thereby predicts the processing that is to be performed in accordance with the processing information of each unit of processing that is synchronized with that previously transmitted or subsequently transmitted content data.
