Transmission apparatus, reception apparatus, communication system, transmission method, reception method, and programs thereof

摘要

[Object] To provide a transmission apparatus, a reception apparatus, a communication system, a transmission method, a reception method, and programs therefor that are capable of efficiently transmitting at least a plurality of pieces of video data included in data of a plurality of contents at the same time. [Solving Means] A switch unit (32a) of a transmission apparatus selects one of a plurality of pieces of video data supplied from a storage apparatus (42) in accordance with video data designated by a transmission data control unit (32i) and supplies it to an IF unit (32b). The IF unit (32b) transmits video data decoded by a decode unit (113) from a terminal (335). The compressed video data supplied from the switch unit (32a) is transmitted via a terminal (336). The terminal (335) is included in a first channel unit. In a case where the IF unit (32b) is an HDMI, for example, the terminal (335) is a terminal for a TMDS channel. The terminal (336) is a terminal that is included in a second channel unit and connected to a reserved line, an HPD line, and the like.

主权项

1. A reception apparatus comprising:
a reception unit that receives first data, which is baseband, from an external device as differential signals via transmitting lines for baseband data, the transmitting lines being included in a high definition multimedia interface (HDMI) cable; a connection status unit that direct current (DC) biases at least one of a pair of differential lines included in the HDMI cable, such that a connection status between the reception apparatus and the external device can be detected at the external device; and a communication unit that receives second data, which is different from the first data, from the external device via a reserved line and a hot plug detect (HPD) line included in the HDMI cable, transmits third data, which is different from the first data, to the external device via the reserved line and HPD line, and subtracts the third data from the second data.
