    • [Object] To prevent image quality deterioration due to unnecessary format conversion.[Solution] An STB (set top box) 200 receives bit stream data that is transmitted from a broadcast station 100 in such a manner as to be carried on a broadcast wave, and obtains stereoscopic image data, audio data, and the like. Furthermore, the STB 200 transmits the stereoscopic image data and the audio data to the TV (television receiver) 300 through the digital interface of HDMI. In a case where the received stereoscopic image data can be handled by a TV 300 and, furthermore, the TV 300 has requested that transmission of the stereoscopic image data be performed without performing format conversion, the STB 200 does not convert the format of the received image data, and transmits the received image data to the TV 300 in the as-is format. Furthermore, in the case of other cases, the STB 200 converts in advance the format of the received stereoscopic image data into, for example, a format that is set by the user, and transmits the stereoscopic image data to the TV 300.
    • [解决方案] STB(机顶盒)200接收从广播台100发送的位流数据,以便在广播波上传送,并获得立体图像数据,音频数据等。 此外,STB200通过HDMI的数字接口将立体图像数据和音频数据发送到TV(电视接收机)300。 在接收到的立体图像数据可以由TV300处理的情况下,并且TV300已经请求在不进行格式转换的情况下执行立体图像数据的发送,STB 200不转换所接收的立体图像数据的格式 并将所接收的图像数据以原样格式发送到TV300。 此外,在其他情况下,STB 200将接收到的立体图像数据的格式预先转换为例如由用户设置的格式,并将立体图像数据发送到TV 300。
