Abstract:
A PC (11) of the present invention comprises a one-segment broadcast tuner (16), a display output I/F (18) for transmitting, to a TV (21), data of a broadcast program received by the one-segment broadcast tuner (16), and a PC-side relay coordination control section (14) for transmitting a channel code for (i) causing the TV (21) to receive, via a digital tuner (26) or an analog tuner (27), a broadcast program containing same content as the broadcast program being received by the one-segment broadcast tuner (16), and (ii) causing the TV (21) to output data of the broadcast program. Therefore, in a case where an output of the TV (21) is switched from the broadcast program being received by the one-segment broadcast tuner (16) to the broadcast program being received by the digital tuner (26) or the analog tuner (27), a user of the PC (11) can continuously watch a broadcast program containing same content as before the output switching. This makes it possible to continuously watch, after an output switching, a broadcast program containing same content as before the output switching.
Abstract(Chinese):

本发明的PC（11）包括单段广播调谐器（16），用于向TV（21）发送由一段接收的广播节目的数据的显示输出I / F（18） 广播调谐器（16）和PC侧中继协调控制部分（14），用于发送用于（i）使TV（21）经由数字调谐器（26）或模拟调谐器（27）接收的信道码， 包含与广播节目正在接收的广播节目相同的广播节目的广播节目，以及（ii）使TV（21）输出广播节目的数据。 因此，在将TV（21）的输出从由单段广播调谐器（16）接收的广播节目切换到由数字调谐器（26）或模拟调谐器（16）接收的广播节目的情况下 27），PC（11）的用户可以连续观看包含与输出切换之前相同的内容的广播节目。 这使得可以在输出切换之后连续地观看包含与输出切换之前相同的内容的广播节目。
