Description
本發明係關於一種監視模組，尤其關於一種能夠有效傳輸高畫質格式之影像串流的監視模組。The present invention relates to a monitoring module, and more particularly to a monitoring module capable of efficiently transmitting a video stream of a high quality format.
圖1顯示一習知監視模組之顯示器所顯示的畫面。如圖1所示，習知的嬰兒監視模組中，利用2.4G專屬協定射頻電路(RF)，作為錄影機(camera)及可攜式顯示器(portable monitor)間的傳輸介面。射頻電路(RF)所能承載之傳輸的資料量小，因此一般影像資料僅採用視頻圖形陣列(英語：Video Graphics Array，簡稱VGA)格式。於圖1之顯示器中，是分別顯示四個VGA格式的影像畫面。Figure 1 shows a screen displayed by a display of a conventional monitoring module. As shown in FIG. 1, the conventional baby monitoring module uses a 2.4G proprietary protocol radio frequency (RF) circuit as a transmission interface between a video camera and a portable monitor. The amount of data transmitted by the radio frequency circuit (RF) is small, so the general image data is only in the video graphics array (English: Video Graphics Array, VGA for short) format. In the display of FIG. 1, four image images of VGA format are respectively displayed.
然而，若要利用2.4G專屬協定射頻電路無線傳輸影像時，射頻電路的頻寬一直是影像畫質的瓶頸。以3Mbps的射頻電路(RF)為例，要傳送H.261 720p的影像，需要圖框速率(frame rates)約20fps。However, if the 2.4G exclusive protocol RF circuit is used to wirelessly transmit images, the bandwidth of the RF circuit is always the bottleneck of image quality. Taking a 3 Mbps radio frequency circuit (RF) as an example, to transmit an H.261 720p image, frame rates of about 20 fps are required.
因此若要讓嬰兒監視模組的顯示器，顯示高畫質(High Definition，簡稱HD)格式的影像時，依據習知技術是無法採用2.4G專屬協定射頻電路(RF)進行無線傳輸，因為2.4G 專屬協定射頻電路的傳輸速度較小，使其無法有效地傳輸高畫質(HD)格式的影像。Therefore, if the monitor of the baby monitor module is to display the image in the High Definition (HD) format, the 2.4G exclusive protocol radio frequency (RF) cannot be used for wireless transmission according to the conventional technology, because 2.4G The proprietary protocol RF circuit has a low transmission speed, making it impossible to efficiently transmit images in high definition (HD) format.
因此，需要發展一種能夠有效傳輸高畫質(HD)格式之影像串流的監視模組；或者能夠同時傳輸更多VGA格式影像串流的監視模組。Therefore, it is necessary to develop a monitoring module capable of efficiently transmitting a video stream of a high definition (HD) format; or a monitoring module capable of simultaneously transmitting more video streams of a VGA format.

The image quality of the high-quality video stream HD transmitted by the second image transmitting device group 212 is higher than the image streams R1 R R5 of the VGA format transmitted by the first image transmitting device group 211.
此外於一實施例，影像處理電路242可以為一影像分格電路，用以將該些影像串流進行分格，使顯示器241能夠以分格方式來顯示該些影像串流。圖4A顯示本發明一實施例之監視模組之顯示器所顯示的畫面。如圖4A，顯示器241分別以九宮格方式來顯示VGA格式的影像串流R1~R9。圖4B顯示本發明一實施例之監視模組之顯示器所顯示的畫面。如圖4B，顯示器241將高畫質格式的影像串流HD顯示於其左上方區塊，而VGA格式的影像串流R1~R5分別顯示於左上方區塊的右側邊及下側邊。In addition, in an embodiment, the image processing circuit 242 can be an image dividing circuit for dividing the image streams to enable the display 241 to display the image streams in a divided manner. 4A shows a screen displayed by a display of a monitoring module in accordance with an embodiment of the present invention. As shown in FIG. 4A, the display 241 displays the video streams R1 to R9 in the VGA format in a nine-square grid manner. 4B shows a screen displayed by the display of the monitoring module in accordance with an embodiment of the present invention. As shown in FIG. 4B, the display 241 displays the video stream HD of the high-definition format in its upper left block, and the video streams R1 R R5 of the VGA format are respectively displayed on the right side and the lower side of the upper left block.
如上所述，依據本發明一實施例的監視模組100，包含具有不相同第一通道及第二通道的第一接收端射頻電路231及第二接收端射頻電路232，能夠同時接收多個影像串流而提高影像串流的速度。於一實施例，第一通道及第二通道分 別在相異的頻率範圍，能夠以分頻多工方式同時地接收影像串流的訊號，因此能夠提高監視模組100接收影像串流的速度。且能夠利用多個發送端射頻電路131來傳輸一個高畫質格式的影像串流HD，克服單一發送端射頻電路131無法有效傳輸高畫質格式之影像串流的缺點，而達到有效傳輸高畫質格式之影像串流的功能。As described above, the monitoring module 100 according to an embodiment of the present invention includes a first receiving end RF circuit 231 and a second receiving end RF circuit 232 having different first channels and second channels, and capable of receiving multiple images simultaneously. Streaming increases the speed of video streaming. In an embodiment, the first channel and the second channel are divided into In the different frequency range, the signal of the video stream can be simultaneously received in the frequency division multiplexing mode, so that the speed of the video stream received by the monitoring module 100 can be improved. Moreover, the plurality of transmitting end radio frequency circuits 131 can be used to transmit a video stream HD of a high-definition format, thereby overcoming the shortcoming of the single-send radio frequency circuit 131 being unable to effectively transmit the video stream of the high-definition format, thereby achieving effective transmission of high-definition pictures. The function of video streaming in quality format.
