影音傳輸系統及影音傳輸設定檢測方法Video and audio transmission system and video and audio transmission setting detection method

本發明為一種影音控制技術,特別是指一種可以檢測影音傳輸設定是否有錯誤的一種影音傳輸系統及影音傳輸設定檢測方法。The present invention relates to an audio-visual control technology, in particular to an audio-visual transmission system and an audio-visual transmission setting detection method which can detect whether there is an error in the audio-visual transmission setting.

請參閱圖1所示,該圖為習用之網路影像傳輸(video over IP)切換系統架構示意圖。網路影像傳輸切換系統1包括有網路切換器10,其藉由網路和多台的傳送器11以及接收器12電性連接。傳送器11和影音資料源14(例如:電腦、多媒體播放器等裝置)電性連接,接收器12則和影音輸出裝置13(例如:顯示器等裝置)電性連接。Please refer to FIG. 1 , which is a schematic diagram of a conventional video over IP switching system. The network video transmission switching system 1 includes a network switch 10 which is electrically connected to a plurality of transmitters 11 and receivers 12 through a network. The transmitter 11 is electrically connected to the audio and video data source 14 (eg, a computer, a multimedia player, etc.), and the receiver 12 is electrically connected to the audio and video output device 13 (eg, a display device, etc.).

在習用技術中,由於傳送器11和接收器12的製造商和網路切換器10的製造商通常並不相同,因此當傳送器11傳輸大量資料(例如:4K多媒體影音,或者是8K或更高解析度的多媒體影音資料)給網路切換器10,然後網路切換器10再將接收到的上述大量資料傳送給接收器12時,往往會因為網路切換器10的網路設定不符合傳送器11傳輸的封包規格,因此造成接收器12接收到封包並解開還原成影音資料時,影音輸出裝置13會有輸出畫面異常的問題。In the conventional technology, since the manufacturer of the transmitter 11 and the receiver 12 is usually different from the manufacturer of the network switch 10, when the transmitter 11 transmits a large amount of data (for example: 4K multimedia video, or 8K or more high-resolution multimedia video data) to the network switch 10, and then the network switch 10 transmits the received large amount of data to the receiver 12, often because the network settings of the network switch 10 do not conform to the The specifications of the packets transmitted by the transmitter 11 cause the problem that the audio and video output device 13 outputs abnormal images when the receiver 12 receives the packets and decompresses them into audio and video data.

當上述問題發生時,由於難以確定是哪一個設定有問題,因此使用者必須要逐一地檢視所有設定,才有可能找出錯誤的設定,此種檢測方式會有耗時與沒有效率的問題。由於前述產生異常的情況發生時,對於網路切換器而言,並非是封包傳輸異常,只是網路切換器沒有根據傳送器所傳輸的封包型態,以適當的網路傳輸模式來傳輸封包,而在現有的技術中,也尚未有適當的技術可以解決。When the above problem occurs, it is difficult to determine which setting is faulty. Therefore, the user must check all the settings one by one in order to find the wrong setting. This detection method is time-consuming and inefficient. When the above-mentioned abnormal situation occurs, for the network switch, it is not a packet transmission abnormality, but the network switch does not transmit the packet in an appropriate network transmission mode according to the type of the packet transmitted by the transmitter. In the existing technology, there is no suitable technology to solve the problem.

爰是之故,有鑑於習知技術之缺失,提出一種影音傳輸系統及影音傳輸設定檢測方法,用以改善上述習用手段之缺失。For this reason, in view of the deficiencies of the prior art, an audio and video transmission system and an audio and video transmission setting detection method are proposed to improve the deficiencies of the above-mentioned conventional means.

However, the following embodiments are not intended to limit the present invention.

請參閱圖2所示,該圖為本發明之影音傳輸系統架構示意圖。在本實施例中,該影音傳輸系統2包括有傳送器21與接收器22。傳送器21與接收器22透過有線網路或者是無線網路和網路切換器20電性連接。網路切換器20,可以選擇為乙太網路交換器(Ethernet switch)或路由器(router),但不以此為限制。在本實施例中,網路切換器20內具有設定資訊200,其係可以關於巨型封包(jumbo frame)設定資訊、網路群組管理協定(Internet Group Management Protocol, IGMP)設定資訊、流量控制(flow control)設定資訊或者是生成樹協定(Spanning Tree Protocol, STP)設定資訊。前述之設定資訊200,例如是儲存在網路切換器20內部的儲存裝置當中(圖未示),其是可用來增加網路傳輸效能,提升網路傳輸效率的設定。Please refer to FIG. 2 , which is a schematic diagram of the structure of the video and audio transmission system of the present invention. In this embodiment, the video and audio transmission system 2 includes a transmitter 21 and a receiver 22 . The transmitter 21 and the receiver 22 are electrically connected to the network switch 20 through a wired network or a wireless network. The network switch 20 can be selected as an Ethernet switch or a router, but not limited thereto. In this embodiment, the network switch 20 has configuration information 200, which can be related to jumbo frame configuration information, Internet Group Management Protocol (IGMP) configuration information, flow control ( flow control) setting information or Spanning Tree Protocol (STP) setting information. The aforementioned setting information 200 is, for example, stored in a storage device (not shown) inside the network switch 20 , which is a setting that can be used to increase network transmission efficiency and improve network transmission efficiency.

在本實施例中,傳送器21透過影音傳輸線材,例如:HDMI線材、DVI線材,但不以此為限制,與影音訊號源24a或24b電性連接。影音訊號源24a在本實施例為播放器,例如DVD播放器,或者是藍光DVD播放器等,但不以此為限制。影音訊號源24b則可以為電腦或者是筆記型電腦等。接收器22除了和網路切換器20電性連接之外,也透過影音傳輸線材,例如:HDMI線材、DVI線材,但不以此為限制,和影音輸出裝置23電性連接。在本實施例中,影音輸出裝置23為顯示器或顯示器與喇叭設備的組合。In this embodiment, the transmitter 21 is electrically connected to the audio and video signal source 24a or 24b through an audio and video transmission cable, such as an HDMI cable and a DVI cable, but not limited thereto. In this embodiment, the audio and video signal source 24a is a player, such as a DVD player, or a Blu-ray DVD player, but not limited thereto. The audio and video signal source 24b may be a computer or a notebook computer. In addition to being electrically connected to the network switch 20, the receiver 22 is also electrically connected to the audio-visual output device 23 through audio-visual transmission cables, such as HDMI cables and DVI cables, but not limited thereto. In this embodiment, the audio-visual output device 23 is a display or a combination of a display and a speaker device.

傳送器21將來自影音訊號源24a或24b所輸出的影音訊號,例如:高畫質的4K多媒體影音資訊,或者是8K或更高的多媒體影音資訊,經過訊號處理轉換成複數個封包,藉由有線或無線網路傳給網路切換器20。網路切換器20接收來自於傳送器21的封包,根據設定資訊處理所接收的封包,並根據封包的目的地輸出給接收器22。接收器22解開接收到的封包,將其還原成影音訊號,經由影音輸出裝置23輸出,產生影像與聲音的資訊。由於網路切換器20內的設定資訊可能因為使用者或者是網路切換器20出廠時預設的設定資訊,而和接收器22與傳送器21傳輸所需的網路設定需求不一致,因而影響網路傳輸效率,造成接收器22無法完整地接收來自於傳送器21所傳輸的封包,導致影音輸出裝置23無法順利出畫,例如:影像撥放停頓、傳輸時間過程無法順利撥放等現象。The transmitter 21 converts the audio and video signals output from the audio and video signal source 24a or 24b, such as high-definition 4K multimedia audio and video information, or 8K or higher multimedia audio and video information, into a plurality of packets through signal processing. The wired or wireless network is passed to the network switch 20 . The network switch 20 receives the packets from the transmitter 21 , processes the received packets according to the setting information, and outputs the packets to the receiver 22 according to the destination of the packets. The receiver 22 unpacks the received packets, converts them into audio and video signals, and outputs them through the audio and video output device 23 to generate video and audio information. Because the setting information in the network switch 20 may be inconsistent with the network setting requirements required by the receiver 22 and the transmitter 21 for transmission due to the user or the default setting information of the network switch 20 when it leaves the factory, it affects the Due to the network transmission efficiency, the receiver 22 cannot completely receive the packets transmitted from the transmitter 21, resulting in the video output device 23 not being able to draw pictures smoothly, for example, the video playback is stopped, and the transmission time process cannot be played smoothly.

例如:傳送器21要傳送的影音資料因為資料量大,因此需要用巨型封包(jumbo frame)來進行傳輸,但如果網路切換器20內部的設定資訊200並非使用巨型封包的設定時,當傳送器21傳送巨型封包給網路切換器20時,網路切換器20因為還是用標準封包傳輸的方式,會因為傳輸時間過長,使得接收器22沒有辦法在特定時間內接收到來自傳送器20的全部封包,致使造成影音輸出裝置23沒有辦法顯示完整的影音資訊。For example, the audio and video data to be transmitted by the transmitter 21 needs to use jumbo frames for transmission because of the large amount of data. When the receiver 21 transmits the jumbo packet to the network switch 20, the network switch 20 still uses the standard packet transmission method, and the transmission time is too long, so that the receiver 22 cannot receive the data from the transmitter 20 within a specific time. , so that the audio-visual output device 23 cannot display complete audio-visual information.

因此,在本發明的一實施例中,透過接收器22將內部設置的封包接收類型設定資訊220,例如:巨型封包(jumbo frame)設定資訊、網路群組管理協定(Internet Group Management Protocol, IGMP)設定資訊、流量控制(flow control)設定資訊或者是生成樹協定(Spanning Tree Protocol, STP)設定資訊,可以在適當時機,例如:安裝完畢上電時,或者是重新啟動時,先主動對傳送器21發出的封包進行判斷,以是先確定網路切換器20的設定資訊是否正確。Therefore, in an embodiment of the present invention, through the receiver 22, the internally set packet receiving type setting information 220, such as: jumbo frame setting information, Internet Group Management Protocol (IGMP) ) setting information, flow control (flow control) setting information, or Spanning Tree Protocol (STP) setting information, you can take the initiative to transmit the information at an appropriate time, such as when the installation is completed and powered on, or when it is restarted. The packet sent by the switch 21 is judged to first determine whether the setting information of the network switch 20 is correct.

要判斷傳送器21所送出來的封包是否正確,在本發明中,可以有不同的實施方式,在一實施例中,傳送器21可以主動周期性的發送測試封包給接收器22,使得接收器22可以根據接收到的封包狀態來進行判斷。在另一實施例中,接收器22可以事先發出傳送指令給傳送器21,然後傳送器21可以根據接收器22所發出的關於封包接收類型設定資訊220的傳送指令,傳送符合封包接收類型設定資訊220的封包。設定資訊220例如是儲存在接收器22內部的儲存裝置當中(圖未示)。之後,接收器22根據封包接收的狀態來判斷網路切換器的設定資訊是否正確。以巨型封包為例,當接收器22要求傳送器21傳輸巨型封包的時候,如果接收器22沒有辦法在預定的時間接收到封包的話,代表中間的網路切換器20的設定資訊200有問題,此時使用者就可以變更設定資訊200,讓巨型封包可以在時間內傳輸到接收器22,以使影音輸出裝置產生正常的影音資訊。To judge whether the packet sent by the transmitter 21 is correct, in the present invention, there can be different implementations. In one embodiment, the transmitter 21 can actively and periodically send test packets to the receiver 22, so that the receiver 22 It can be judged according to the received packet status. In another embodiment, the receiver 22 may issue a transmission command to the transmitter 21 in advance, and then the transmitter 21 may transmit the corresponding packet reception type setting information according to the transmission instruction about the packet reception type setting information 220 sent by the receiver 22 220 packets. The setting information 220 is, for example, stored in a storage device inside the receiver 22 (not shown). Afterwards, the receiver 22 determines whether the setting information of the network switch is correct according to the state of packet reception. Taking the jumbo packet as an example, when the receiver 22 requests the transmitter 21 to transmit the jumbo packet, if the receiver 22 cannot receive the jumbo packet at the predetermined time, it means that there is a problem with the setting information 200 of the intermediate network switch 20, At this time, the user can change the setting information 200 so that the jumbo packet can be transmitted to the receiver 22 within a certain time, so that the audio-visual output device can generate normal audio-visual information.

如圖3所示,該圖本發明之影音傳輸設定檢測方法之一實施例流程示意圖。利用圖2所示的架構,可歸納出如圖3所示的操作流程,以判斷出網路切換器20的設定資訊是否正確。在圖3的步驟30中,將傳送器21以及接收器22與具有設定資訊之網路切換器20電性連接,形成如圖2的架構。接著進行步驟31,設定接收器22的封包接收類型。本步驟中的封包接收類型可以為關於巨型封包設定資訊、網路群組管理協定設定資訊、流量控制(設定資訊或者是生成樹協定設定資訊)等,但不以此為限制。然後進行步驟32,使該網路切換器20接收來自於傳送器21所傳送的符合該封包接收類型的測試封包,並根據該設定資訊輸出測試封包。最後進行步驟33,根據接收器22是否接收到測試封包來判斷設定資訊是否正確。As shown in FIG. 3 , it is a schematic flowchart of an embodiment of the video and audio transmission setting detection method of the present invention. Using the structure shown in FIG. 2 , the operation flow shown in FIG. 3 can be summarized to determine whether the setting information of the network switch 20 is correct. In step 30 of FIG. 3 , the transmitter 21 and the receiver 22 are electrically connected to the network switch 20 having the setting information to form the structure of FIG. 2 . Next, go to step 31 to set the packet receiving type of the receiver 22 . The packet receiving type in this step may be about jumbo packet setting information, network group management protocol setting information, flow control (setting information or spanning tree protocol setting information), etc., but not limited thereto. Then, step 32 is performed to enable the network switch 20 to receive the test packet from the transmitter 21 that conforms to the packet receiving type, and output the test packet according to the setting information. Finally, step 33 is performed to determine whether the setting information is correct according to whether the receiver 22 receives the test packet.

在步驟32與33的流程中,因為網路接收器20在收到傳送器21所傳來的測試封包之後,會根據自身的設定資訊將測試封包轉傳給接收器22,因此只要網路切換器20的設定資訊無法符合傳送器21與接收器22之間的傳送需求,在接收器22收到測試封包之後,可以根據接收的狀態,判斷出網路切換器20的設定資訊是否有問題。其中前述的狀態,係根據設定資訊的不同而有所不同,例如,設定資訊如果是巨型封包的話,則接收器可以根據接收到封包所需的時間是否有超過預定的時間來判斷設定資訊是否正確,如果是IGMP的話,則可以根據接收器22是否有接收到屬於同群組或來自不同群組的傳送器的測試封包來進行判斷。In the process of steps 32 and 33, after receiving the test packet from the transmitter 21, the network receiver 20 will forward the test packet to the receiver 22 according to its own setting information, so as long as the network switches The setting information of the switch 20 cannot meet the transmission requirements between the transmitter 21 and the receiver 22. After the receiver 22 receives the test packet, it can judge whether the setting information of the network switch 20 has any problem according to the receiving state. The aforementioned states vary according to different configuration information. For example, if the configuration information is a jumbo packet, the receiver can determine whether the configuration information is correct according to whether the time required to receive the packet exceeds a predetermined time. , if it is IGMP, it can be judged according to whether the receiver 22 has received a test packet belonging to the same group or from a transmitter of a different group.

以下列舉出不同種類設定資訊的具體判斷實施例,來進一步說明本發明的影音傳輸設定檢測方法流程,如圖3A所示,該圖為本發明之影音傳輸設定檢測方法實施例流程示意圖。在本實施例中,流程3a包括有下列步驟,首先進行步驟30a,提供如圖2所示的影音傳輸系統。接著進行步驟31a,透過有線或無線網路連接的方式,將傳送器21以及接收器22與具有設定資訊200之網路切換器20電性連接。接著進行步驟32a,設定接收器22的封包接收類型。本步驟中,封包接收類型為巨型封包。Specific judging embodiments of different types of setting information are listed below to further illustrate the process flow of the video and audio transmission setting detection method of the present invention, as shown in FIG. In this embodiment, the process 3a includes the following steps. First, step 30a is performed to provide the video and audio transmission system as shown in FIG. 2 . Next, step 31a is performed to electrically connect the transmitter 21 and the receiver 22 to the network switch 20 having the setting information 200 through a wired or wireless network connection. Next, step 32a is performed to set the packet receiving type of the receiver 22 . In this step, the packet receiving type is jumbo packet.

接下來以步驟33a,傳送器21週期性地將屬於巨型封包的測試封包傳給網路接收器20。然後步驟34a,使網路切換器20接收測試封包,並根據設定資訊輸出封包給接收器22。最後進行步驟35a根據接收器22是否接收到測試封包來判斷網路切換器內的設定資訊是否正確。在步驟35a中,如圖 4A與圖4B所示,該圖分別為步驟35a判斷是否接收到測試封包的一實施例示意圖。如圖4A所示,接收器22都有接收到傳送器21週期性所傳的測試封包,代表網路切換器20的設定資訊配置是正常的。反之,如圖4B所示,接收器22一直無法接收到來自於傳送器21週期性所傳的測試封包,代表網路切換器20的設定資訊有錯誤。Next in step 33a, the transmitter 21 periodically transmits the test packets belonging to the jumbo packets to the network receiver 20. Then in step 34a, the network switch 20 receives the test packet, and outputs the packet to the receiver 22 according to the setting information. Finally, step 35a is performed to determine whether the setting information in the network switch is correct according to whether the receiver 22 receives the test packet. In step 35a, as shown in FIG. 4A and FIG. 4B, the figures are respectively a schematic diagram of an embodiment of determining whether a test packet is received in step 35a. As shown in FIG. 4A , the receivers 22 all receive the test packets periodically transmitted by the transmitter 21 , which means that the configuration of the setting information of the network switch 20 is normal. On the contrary, as shown in FIG. 4B , the receiver 22 has been unable to receive the test packets periodically transmitted from the transmitter 21 , which means that the setting information of the network switch 20 is wrong.

如圖3B所示,該圖為本發明之影音傳輸設定檢測方法實施例流程示意圖。在本實施例中,流程3b包括有下列步驟,首先進行步驟30b,提供如圖2所示的影音傳輸系統。接著進行步驟31b,透過有線或無線網路連接的方式,將傳送器21以及接收器22與具有設定資訊200之網路切換器20電性連接。接著進行步驟32b,設定接收器22的封包接收類型。本步驟中,封包接收類型為巨型封包。As shown in FIG. 3B , which is a schematic flowchart of an embodiment of a method for detecting video and audio transmission settings according to the present invention. In this embodiment, the process 3b includes the following steps. First, step 30b is performed to provide the video and audio transmission system as shown in FIG. 2 . Next, step 31b is performed to electrically connect the transmitter 21 and the receiver 22 to the network switch 20 having the setting information 200 through a wired or wireless network connection. Next, step 32b is performed to set the packet receiving type of the receiver 22 . In this step, the packet receiving type is jumbo packet.

接下來以步驟33b,使接收器22通知傳送器21傳送符合封包接收類型的測試封包。本步驟中,接收器22透過網路切換器20將指定對應封包接收類型發送給傳送器21。接下來,進行步驟34b傳送器21將屬於巨型封包的測試封包傳給網路接收器20。然後步驟35b,使網路切換器20接收測試封包,並根據設定資訊輸出封包給接收器22。最後進行步驟36b根據接收器22是否在預設時間內接收到測試封包來判斷網路切換器20內的設定資訊是否正確。Next, in step 33b, the receiver 22 notifies the transmitter 21 to transmit a test packet conforming to the packet receiving type. In this step, the receiver 22 sends the specified corresponding packet receiving type to the transmitter 21 through the network switch 20 . Next, go to step 34b. The transmitter 21 transmits the test packet belonging to the jumbo packet to the network receiver 20. Then in step 35b, the network switch 20 receives the test packet and outputs the packet to the receiver 22 according to the setting information. Finally, step 36b is performed to determine whether the setting information in the network switch 20 is correct according to whether the receiver 22 receives the test packet within the preset time.

在步驟36b的一實施例中,如圖 4C與圖4D所示,該圖分別為步驟36b的實施例示意圖。本實施例基本上與圖3A所示的步驟35a類似,差異的是接收器22會為了確認網路切換器20設定資訊是否正確,接收器22內設定有等待時間。 等待時間通常是 傳送器21發送時間間隔的n> 1倍以上,如圖4A所示,如果在n倍時間間隔內收到了來自傳送器21所傳的測試封包,代表網路切換器20的設定資訊配置是正常的。反之,如圖4B所示,如果在n倍時間間隔內完全沒有收到,代表網路切換器20的設定資訊配置有問題,或者是就算配置沒有問題,網路封包丟失嚴重,這樣的網路切換器20環境也是不可用的。In an embodiment of step 36b, as shown in FIG. 4C and FIG. 4D, the figures are schematic diagrams of the embodiment of step 36b, respectively. This embodiment is basically similar to step 35a shown in FIG. 3A , the difference is that the receiver 22 has a waiting time set in the receiver 22 in order to confirm whether the setting information of the network switch 20 is correct. The waiting time is usually n>1 times the transmission time interval of the transmitter 21. As shown in FIG. 4A, if the test packet from the transmitter 21 is received within n times the time interval, it represents the setting of the network switch 20. Information configuration is normal. On the contrary, as shown in FIG. 4B , if it is not received at all within n times the time interval, it means that there is a problem with the configuration of the setting information of the network switch 20 , or even if there is no problem with the configuration, the network packet loss is serious, such a network The switcher 20 environment is also unavailable.

請參閱圖5A所示,該圖為本發明之影音傳輸設定檢測方法另一實施例流程示意圖。在本實施例中,流程3c包括有下列步驟,首先進行步驟30c,提供如圖2所示的影音傳輸系統。接著進行步驟31c,將傳送器21以及接收器22經由有線網路或無線網路的方式與具有設定資訊200之網路切換器20電性連接。接著進行步驟32c,設定接收器22的封包接收類型。本步驟中,封包接收類型為網路群組管理協定(IGMP)類型下的偵聽(snooping)設定。此設定的主要目的在於避免網路切換器使用廣播(broadcast)的方式,佔用切換器上特定埠(port)的頻寬,因此採用多點廣播(multicast)的方式來進行封包發送。IGMP snooping的設定資訊下,網路切換器會記錄特定埠上的成員加入或離開,如果一個埠上不存在多點廣部群組的成員,網路切換器就不會把多點廣播的封包送給該埠。Please refer to FIG. 5A , which is a schematic flowchart of another embodiment of the video and audio transmission setting detection method of the present invention. In this embodiment, the process 3c includes the following steps. First, step 30c is performed to provide the video and audio transmission system as shown in FIG. 2 . Next, step 31c is performed, and the transmitter 21 and the receiver 22 are electrically connected to the network switch 20 having the setting information 200 via a wired network or a wireless network. Next, step 32c is performed to set the packet receiving type of the receiver 22 . In this step, the packet receiving type is the snooping setting under the Internet Group Management Protocol (IGMP) type. The main purpose of this setting is to prevent the network switch from using the broadcast method to occupy the bandwidth of a specific port on the switch. Therefore, the multicast method is used to send packets. Under the setting information of IGMP snooping, the network switch will record the joining or leaving of members on a specific port. If there is no multicast group member on a port, the network switch will not send multicast packets. to this port.

接下來以步驟33c,傳送器21週期性地對特定的多點廣播群組發送廣播測試封包給網路接收器20。然後步驟34c,使網路切換器20接收測試封包,並根據設定資訊輸出封包給接收器22。最後進行步驟35c根據接收器22是否接收到測試封包來判斷網路切換器20內的設定資訊是否正確。Next, in step 33c, the transmitter 21 periodically sends a broadcast test packet to the network receiver 20 for a specific multicast group. Then in step 34c, the network switch 20 receives the test packet and outputs the packet to the receiver 22 according to the setting information. Finally, step 35c is performed to determine whether the setting information in the network switch 20 is correct according to whether the receiver 22 receives the test packet.

在步驟35c中,如圖6A與圖6B所示,該圖為步驟35c的一實施例示意圖。如圖6A所示,如果傳送器21和接收器22隸屬於不相同的多點廣播群組,則接收器22沒有接收到來自於傳送器21的廣播測試封包的話,代表網路切換器20內的設定資訊正確。反之,如圖6B所示,如果接收器22有接收到來自傳送器21所發出的廣播測試封包的話,代表設定資訊錯誤。此時,使用者可以透過修改網路切換器20內部的設定資訊,將傳送器21與切換器22修改成不相關的多點廣播群組。In step 35c, as shown in FIG. 6A and FIG. 6B, the figure is a schematic diagram of an embodiment of step 35c. As shown in FIG. 6A , if the transmitter 21 and the receiver 22 belong to different multicast groups, the receiver 22 does not receive the broadcast test packet from the transmitter 21 , which means that the network switch 20 The setup information is correct. On the contrary, as shown in FIG. 6B , if the receiver 22 receives the broadcast test packet sent from the transmitter 21 , it means that the setting information is wrong. At this time, the user can modify the transmitter 21 and the switch 22 into an unrelated multicast group by modifying the setting information inside the network switch 20 .

如圖5B所示,該圖為本發明之影音傳輸設定檢測方法另一實施例流程示意圖。在本實施例中,是用來進行網路切換器20在IGMP 偵聽模式下的快速離開(fast leave)設定資訊的判斷流程。在正常IGMP偵聽的模式下,與網路切換器20的特定埠電性連接的裝置如果要離開該埠,會有下列幾個程序。首先第一步網路切換器20的下層的多點廣播群組成員發出離開的請求,接著第二步網路切換器20收到以後向該成員發出確認訊息(query),第三步在送出離開請求的群組成員收到之後,不會回應這個網路切換器發出的確認訊息。第四步中,網路切換器20經過一段時間收不到回覆,便將該成員移出群組。由於在第三步到第四步中,需要經過一段等待時間,因此產生了所謂快速離開的需求。在快速離開的設定資訊下,一但網路切換器20收到了脫離的資訊,便會立即停止對該成員發出多點廣播的封包。As shown in FIG. 5B , the figure is a schematic flowchart of another embodiment of the video and audio transmission setting detection method of the present invention. In this embodiment, the process is used to determine the fast leave setting information of the network switch 20 in the IGMP snooping mode. In the normal IGMP snooping mode, if a device electrically connected to a specific port of the network switch 20 wants to leave the port, the following procedures will be performed. In the first step, the member of the multicast group at the lower layer of the network switch 20 sends a request to leave, then in the second step, the network switch 20 sends a confirmation message (query) to the member after receiving it, and in the third step, it sends The group member who received the leave request will not respond to the confirmation message from this network switch. In the fourth step, the network switch 20 removes the member from the group if no reply is received after a period of time. Since in the third to fourth steps, a waiting time is required, so-called quick departure is required. Under the fast leave setting information, once the network switch 20 receives the leave information, it will immediately stop sending multicast packets to the member.

在圖5B中,流程3d包括有下列步驟,首先進行步驟30d,提供如圖2所示的影音傳輸系統。接著進行步驟31d,將傳送器21以及接收器22與具有設定資訊200之網路切換器20電性連接。接著進行步驟32d,設定接收器的封包接收類型。本步驟中,設定的程序中將接收器22加入與傳送器21相同的多點廣播群組,而封包接收類型為設定為網路群組管理協定。In FIG. 5B , the process 3d includes the following steps. First, step 30d is performed to provide the video and audio transmission system shown in FIG. 2 . Next, step 31d is performed to electrically connect the transmitter 21 and the receiver 22 to the network switch 20 having the setting information 200 . Next, step 32d is performed to set the packet receiving type of the receiver. In this step, the receiver 22 is added to the same multicast group as the transmitter 21 in the setting procedure, and the packet receiving type is set to the network group management protocol.

接下來以步驟33d,傳送器21按照一定的時間間隔週期性地對特定的多點廣播群組發送廣播測試封包給網路接收器20。然後步驟34d,使網路切換器20接收測試封包,並根據設定資訊輸出封包給接收器22。接著進行步驟35d,讓接收器22脫離與傳送器21相同的多點廣播群組。此時,傳送器21按照一定的時間間隔週期性地對特定的多點廣播群組發送廣播測試封包給網路接收器20,網路切換器20接收測試封包,並根據設定資訊輸出封包給接收器22。最後進行步驟36d,根據接收器22是否接收到測試封包來判斷網路切換器內的設定資訊是否正確。Next, in step 33d, the transmitter 21 periodically sends a broadcast test packet to the network receiver 20 for a specific multicast group at a certain time interval. Then in step 34d, the network switch 20 receives the test packet, and outputs the packet to the receiver 22 according to the setting information. Then proceed to step 35d to let the receiver 22 leave the same multicast group as the transmitter 21 . At this time, the transmitter 21 periodically sends a broadcast test packet to a specific multicast group at a certain time interval to the network receiver 20, and the network switch 20 receives the test packet and outputs the packet to the receiver according to the setting information. device 22. Finally, step 36d is performed to determine whether the setting information in the network switch is correct according to whether the receiver 22 receives the test packet.

在步驟36d中,如圖6C與圖6D所示,該圖為步驟36d的一實施例示意圖。如圖6C所示,接收器22在送出快速離開設定資訊之後,如果沒有再接收到傳送器21發出的廣播測試封包的話, 代表網路切換器20的設定資訊正確。反之,如圖6D所示,如果接收器22繼續接收到來自該群組傳送器21所發出的廣播測試封包的話, 代表網路切換器的設定資訊錯誤。In step 36d, as shown in FIG. 6C and FIG. 6D, the figure is a schematic diagram of an embodiment of step 36d. As shown in FIG. 6C , if the receiver 22 does not receive the broadcast test packet sent by the transmitter 21 after sending the quick leave setting information, it means that the setting information of the network switch 20 is correct. On the contrary, as shown in FIG. 6D , if the receiver 22 continues to receive the broadcast test packet from the group transmitter 21 , it means that the setting information of the network switch is wrong.

綜合上述的實施例,本發明透過傳送器經由具有設定資訊的網路切換器發送特定的封包給接收器,接收器於接收封包的過程中,可以根據是否接收到封包來判斷網路切換器的設定資訊,例如:巨型封包、IGMP設定、或者是擴展樹協定或流程控制協定等關於網路傳輸效能的設定是否正確。藉由本發明的方式,可以讓接收器自動地判斷網路切換器的設定是否符合所需的封包傳輸類型,也可以檢測出雖然沒有傳輸錯誤,但是不符合接收器需求的封包而導致的影音輸出裝置無法正常輸出影音資訊的問題,進而可以避免影音輸出裝置產生異常畫面,以及可以減少檢測網路切換器設定所需的時間,提升設定的效率。In view of the above-mentioned embodiments, the present invention transmits a specific packet to the receiver through the network switch with setting information through the transmitter, and the receiver can determine whether the network switch is in the process of receiving the packet according to whether the packet is received or not. Configuration information, such as: Jumbo packets, IGMP settings, or whether the settings for the network transmission performance such as the expansion tree protocol or the flow control protocol are correct. By the method of the present invention, the receiver can automatically determine whether the setting of the network switch meets the required packet transmission type, and it can also detect the video output caused by the packet that does not meet the requirements of the receiver although there is no transmission error. The problem that the device cannot output video and audio information normally can prevent the video and audio output device from generating abnormal images, and can reduce the time required for detecting the setting of the network switch, thereby improving the efficiency of the setting.
