When determining about the predetermined set program, when whether only having write down data-signal, program category determining section 402 is by using the content descriptors as describing in the program planning information of using in ARIB STS-B10 digital broadcasting, according to main classification/classification (majorclassification by category) or middle classification/classification (intermediateclassification by category), determine.

For example, when main classification/classification is " news/news report ", " physical culture ", " information/tabloid " or ought main classification/classification is " hobby/education ", and middle classification/classification determines that it is useful only using packet when being " talk/language ", " child/pupil ", " university student/admission examination ", " junior school student/middle school student " and " life-long education/qualification ".

In basic demand is in the time of can determining as a result, as the main classification/classification at the program of booking situation be " physical culture " and middle classification/classification be under the situation of " baseball ", " football ", " golf " etc., then receive data-signal off and on, as under the situation of the digital broadcasting receiving apparatus of second embodiment.Only the result is registered as data-signal, as final data, thereby can reduce power consumption and the amount that is recorded in the recording section 117 significantly.

Figure 11 shows the example of the broadcasted content shown in reception off and on and the kymogram 3 (a).

In this case, determined the airtime, therefore preferably in off-the-air a few minutes before the time, beginning reception intermittently.

Usually, under the situation of sports cast, broadcasting is real-time.Therefore, in most cases the off-the-air time before or after arranging the time.

When the off-the-air of match early the time, as a rule, because the restriction of program, the result's that can play continuously sports commentary and interview.Only under rare occasion, broadcasting finished before arranging the time.Therefore, preferably a few minutes before the off-the-air time, carry out intermittently receiving operation, till off-the-air.

Under the situation of the sports broadcast of for example baseball, football etc., most of motion cost one hour or longer (most of motion cost two hours or longer), thus need a large amount of power receive all broadcasting, so battery has heavier burden.

As mentioned above, when the digital broadcasting receiving apparatus that has a portable phone 100 of broadcast receiving function when utilization writes down this sports broadcast, must be right after in (near the program end) before the end of match, receive and write down this broadcasting off and on, so that reduce the amount of record and the power consumption of recording section 117.
