通信系统、发送设备、接收设备、通信方法及程序
摘要：
本发明涉及能够在HDMI(R)等中执行高效数据发送的通信系统、发送设备、接收设备、通信方法及程序。HDMI(R)信源(53)基于E－EDID的VSDB来判定HDMI(R)信宿(61)是否能够接收子信号。当HDMI(R)信宿(61)能够接收子信号时，HDMI(R)信源(63)将子信号添加到由比特数目小于发送器(72)发送的发送像素数据的比特数目的像素数据组成的主图像的像素数据，从而构造发送像素数据。该数据被发送器(72)通过TMDS信道#0至#2发送。另外，HDMI(R)信源(53)在垂直消隐时段的控制时段中发送包含指示在发送像素数据中是否包含子信号的子信号信息的一般控制分组。本发明例如可应用到HDMI(R)。
摘要（英）：

Provided are a communication system, a transmission device, a reception device, a communication method, and a program capable of performing effective data transmission in an HDMI(R). An HDMI(R) source (53) judges whether an HDMI(R) sink (61) can receive a sub signal according to VSDB of E-EDID. If the HDMI(R) sink (61) can receive the sub signal, transmission pixel data is configured by adding the sub signal to main image pixel data formed by pixel data having a smaller number of bits than the transmission pixel data transmitted from a transmitter (72) and is transmitted by the transmitter (72) via TMDS channel #0 or #2. Moreover, the HDMI(R) source (53) transmits a general control packet including sub signal information expressing whether the transmission pixel data contains a sub signal in the vertical fly-back section control section. The present invention can be applied, for example, to HDMI(R).
