The skilled artisan will have a better understanding of the nature of the invention. <First Embodiment> First, Fig. 1 shows an electronic device 100 for automatically searching for alternative video content according to the first embodiment of the present invention. The electronic device 丨〇〇 includes a display unit 丨|〇, a switching unit 丨20, a detecting unit 130' operating unit 丨40, and a searching unit 丨50. The switching unit 丨2〇 is electrically connected to the 201240462 display unit 110 and the plurality of signal sources 1U, 112, 113, 114; the detecting unit is electrically connected to the unit (10); and the unit (10) is electrically connected to the guessing unit. The unit 13 is electrically connected to the operation unit 14A, the plurality of signal sources u, 112, 114, and the switching unit 120. It should be noted that the switching unit i2〇, the detecting unit 130, the capturing unit 14〇, and the searching unit 15〇 can be implemented in various forms, such as a complete hardware embodiment, a complete software embodiment (including toughness, Permanently inclined, difficult scales, or can be implemented as a form of software and hardware. The plurality of signal sources 111, 112, 113, 114 include: a network server VCD player, a DVD player, a Blu-ray disc player, a cassette recorder, an analog television broadcast, a digital television broadcast, etc. However, the present invention is not limited to this. In addition, the plurality of signal sources iu, m, 113, and 114 respectively correspond to a plurality of video contents. In this embodiment, the electronic device 100 can be a television device. Initially, the switching unit 120 receives the first video content of one of the signal sources, and the first video interface content is displayed on the display unit 11G. Whether the signal specification value of the video content of the side single & 丨3〇 side is lower than a critical value. If so, the detecting unit 13 generates a capture control signal. The signal specification value of the invention towel _ unit 13 包含 includes: a signal strength value, a resolution value, or a signal type, or a combination thereof. It should be noted that the signal specification values of the present invention are not limited thereto. In addition, different signal specification values correspond to different threshold values. For example, when the signal specification value detected by the detecting unit 130 is the signal strength value, the corresponding threshold for comparison is set to 60 dB, in other words, the detecting unit 〇3 〇 detects the first view. The operation control signal is generated when the intensity value of the 5-hole number of the content is lower than 60 dB. Similarly, when the signal specification value detected by the detecting unit 丨30 is the resolution value, the comparison is performed by °; the 201240462 threshold is set to 720*480 (the resolution of the DVD specification), in other words, the detection unit is only required. The 130 detects that the resolution value of the first video content is lower than 720*480, and generates a capture control signal. Alternatively, when the signal specification value detected by the detecting unit 130 is a signal type (for example, a difference between CVBS, YCbCr, HDMI, or a difference between an analog signal and a digital signal), the corresponding threshold value for comparison is used. For the YCbCr (the quality of the signal type is CVBS < YCbCr < HDMI ' analog signal < digital signal), in other words, as long as the detection unit 130 detects that the signal type of the first video content is lower than YCbCr, the capture control signal is generated. The present invention is not limited to the types of signal specification values and threshold values described above. The capturing unit 140 extracts content information of the first video content according to the capturing control signal, and the content information may include: a content name, a broadcast program channel number, a television station name, a playing content time period, or a content length, or other automatic identification The first video content of the f message ' or a combination of the above. For example, 'When the first-view helper comes from the analog TV broadcast unit! 40 may extract the content information of the first-message content from the television information (10) included in the vertical blanking imerval/VBI, for example, the first video content is a movie. The content is the name of the movie. In another embodiment, when the first view content is from a digital television broadcast, the capture unit 14 can extract the first video content from an electronic program guide (Ερ(}) of the first video content. Content information. Regarding digital TV broadcasting standards, please refer to, for example, postal services.
