[0058] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0059] Traditionally, TVs and set-top boxes are connected via point-to-point video cables (HDMI, etc.). Figure 1 As shown, it is a schematic diagram of the traditional connection between a set-top box and a TV, including a set-top box and its remote control, a TV and its remote control, and an HDMI baseband video transmission cable. This traditional connection method has the following technical characteristics and limitations:

[0060] (1) The connection between the set-top box and the TV requires an HDMI cable;

[0061] (2) Set-top boxes and TVs require HDMI encoding and decoding processors, which consumes hardware resources;

[0062] (3) Traditional point-to-point physical transmission connections do not conform to the technological development trend of the Internet and wireless network connections;

[0063] (4) The simplification of smart TV remote controls has made it more complicated for users to switch signal sources through the remote control, resulting in a decrease in the usage rate of set-top boxes.

[0064] Therefore, how to solve the problem that it is difficult for users to switch the signal source of the set-top box video output on the smart TV, and how to economically and efficiently utilize the set-top box and the smart TV, and utilize the interconnection capability of the home local area network to realize the interconnection of multiple video terminals through the video streaming network while ensuring the security and controllability of the operator's video services are the main issues addressed by the present invention.

[0065] The following embodiments of the present invention provide a communication connection method between a television and a set-top box, a set-top box and a television. The television and the set-top box are connected to each other through a broadband local area network. The regional interconnection capability of the broadband local area network is utilized to replace the traditional point-to-point video connection cable (HDMI, etc.), thereby realizing dynamic interconnected video transmission of multiple video terminals, and the transmission route can be set through application software. At the same time, the present invention realizes video processing technology for dynamic interconnection of networked audio and video through a broadband local area network, removes traditional baseband audio and video input ports and processing units, thereby reducing the cost of the entire machine.

[0066] See also Figure 2 As shown, the present invention provides a hardware application scenario schematic diagram of a communication connection method between a television and a set-top box, wherein the television and the set-top box are connected to each other through a broadband local area network, and a video stream transmission service is performed between the set-top box and the television through the broadband local area network, that is, the audio and video output of the set-top box is converted into a video stream, and the video stream service is transmitted to the television through the broadband local area network.

[0067] The communication connection method between a television and a set-top box provided in the embodiment of the present invention is not limited to application to one television, but can also be applied to multiple televisions at the same time. It can realize the simultaneous transmission of video streams in the set-top box to multiple televisions, realize simultaneous decoding, playback and presentation on multiple televisions, and realize networked interconnection between different video terminals.

[0068] See also Figure 3 As shown, it is a schematic diagram of the innovative video transmission technology concept based on broadband local area network proposed by the present invention, including a set-top box and its remote control, a TV and its remote control, and a broadband local area network. This innovative video transmission technology concept has the following technical features and limitations:

[0069] (1) The connection between the set-top box and the TV is via a broadband local area network;

[0070] (2) Convert the audio and video output of the set-top box into a video stream;

[0071] (3) The video streaming server transmits the video to the video player on the TV through the broadband local area network for decoding, playback and presentation.

[0072] In the above-mentioned innovative video transmission technology, the TV and the set-top box are connected through broadband LAN communication. Under the premise of ensuring the security and controllability of the operator's video services, the set-top box and the smart TV can be used economically and efficiently, and the interconnection capability of the home LAN can be used to realize the interconnection of multiple video terminals through the video streaming network. However, the remote control signals of the TV and the set-top box are controlled by different remote controls respectively, which cannot solve the problem of the difficulty of users switching signal sources when the video output of the set-top box is on the smart TV.

[0073] In order to further solve the problem that it is difficult for users to switch signal sources when the video output of the set-top box is on a smart TV, the present invention Figure 3 Based on the innovative video transmission technology shown in the Figure 4 As shown, the present invention proposes a schematic diagram of a communication connection method between a set-top box and a television based on a broadband local area network, including a set-top box, a television, a U box and its remote control, and a broadband local area network. The method has Figure 3 All the features of the innovative video transmission technology shown, for example: the connection between the set-top box and the TV is connected through a home LAN; the audio and video output of the set-top box is converted into a video stream; the video stream service is transmitted to the video player on the TV through a broadband LAN to achieve decoding, playback and presentation; at the same time, in this method, by using a micro U box with a USB port and its smart remote control, unified smart set-top box and smart TV application control is achieved, solving the problem of difficulty in user switching signal source control of the set-top box video output on the smart TV. The market success of this invention can help realize the network design of a new generation of smart TVs and set-top boxes, eliminating traditional baseband video output and input ports and their processing circuits.

[0074] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0075] See also Figure 5 As shown, this embodiment provides a communication connection method between a television and a set-top box, which is applied to a television, and the television and the set-top box are connected to each other through a broadband local area network communication; the method includes:

[0076] Step S11, the television receives a remote control signal, and sends a video stream service request to the broadband local area network based on the triggering of the remote control signal;

[0077] Step S12, the television receives the video stream output by the set-top box through the broadband local area network;

[0078] Step S13: The television parses and plays the video stream.

[0079] The sequence of steps for implementing the communication connection method between a television and a set-top box described in this embodiment includes but is not limited to the sequence of steps listed in this embodiment. Any adjustment of the sequence of the prior art in the art or replacement of the steps with the prior art according to the steps listed in this embodiment are included in the protection scope of the present invention.

[0080] In one embodiment of the present invention, the remote control signal is a Bluetooth remote control signal; the Bluetooth remote control signal is sent by a Bluetooth remote control; the Bluetooth remote control is provided with a start button for triggering the generation of a one-key start video transmission instruction.

[0081] Specifically, the remote control signal is sent by the Bluetooth remote control paired with the U box. Among them, the U box is an intelligent hardware product with a USB physical interface, which supports Bluetooth communication, and forms a U box product with the paired Bluetooth remote control. It is installed on the USB port of the smart TV, and the U box driver software MSIPlayer is installed on the smart TV. At the same time, the latest version of the integrated MSIServer service software is installed on the set-top box, so that the set-top box and the TV are connected through the U box pairing. If the MSIServer service software is installed on the set-top box, it is necessary to ensure that the system software of the set-top box is upgraded to the latest version including the integrated MSIServer service software to ensure that the set-top box and the TV are successfully connected through the U box pairing. After the installation is successful, the set-top box and the TV are successfully connected through the U box pairing. The user presses the red TV button on the Bluetooth remote control of the U box to activate the U box to enter the one-key screen switching working state. Among them, MSIPlayer is a player application specially designed for smart TVs, set-top boxes, and projectors; it has a minimalist interface design and is simple to operate. It supports playing videos in external storage devices, and can also be played by manually entering the video stream address. MSIServer is a service software installed on the set-top box, which mainly integrates the functions of encoding, streaming and pairing players. In one embodiment of the present invention, the Bluetooth remote control includes a Bluetooth transmitter and a Bluetooth receiver; the Bluetooth receiver is connected to the TV through a pluggable interface.

[0082] Specifically, the pluggable interface may be a USB interface, the Bluetooth receiver is a U box with a USB physical interface, the U box is connected to the TV via a USB port, and the Bluetooth transmitter is a Bluetooth remote controller matched with the U box.

[0083] In one embodiment of the present invention, the television has a built-in Bluetooth receiver that can be matched and communicated with the Bluetooth remote control.

[0084] Specifically, the television has a built-in Bluetooth receiver, which is connected to the Bluetooth remote controller for matching communication by receiving a Bluetooth signal sent by a Bluetooth transmitter on the Bluetooth remote controller.

[0085] It should be noted that the present invention does not exclude other connection methods other than connecting the Bluetooth remote control to the smart TV via a U box installed in a USB port, such as connecting the smart remote control to the smart TV via Bluetooth, wireless network, etc., and does not exclude smart TVs other than Android, such as Apple TV. Other connection methods do not conflict with the basic principles and novelty of the present invention and can be regarded as another implementation case. No specific restrictions are made here.

[0086] In one embodiment of the present invention, the television sends a video stream service request to the broadband local area network based on the triggering of the remote control signal, including:

[0087] The television triggers calling MSIPlayer based on the remote control signal;

[0088] The MSIPlayer outputs a video stream service request.

[0089] For example, the specific process of the MSIPlayer outputting the video stream service request is as follows:

[0090] 1. The MSI player uses the handshake protocol in the RTSP (Real Time Streaming Protocol) low-latency streaming media protocol to send an OPTIONS request (i.e., requesting available methods) to the local area network segment where the set-top box is located. If there is an MSIServer in the network segment that replies to the MSI player and includes an available method in the message, the addressing is successful. MSIPlayer can form an available playback address based on the pre-set port number and the IP address of the MSIServer and perform subsequent playback behavior.

[0091] 2. After receiving the response from the server in the previous step, the MSI player, as a client, sends a DESCRIBE request to the MSIServer according to the playback address to obtain the media information of the video stream output by the set-top box for decoding. The DESCRIBE request is used to request the session description information SDP (Session Description Protocol) from the server.

[0092] 3. After receiving the response from the server in the previous step, the client initiates a SETUP request to the server. The request information specifies the transmission mode (TCP / UDP) of the audio and video data packets and the port number used. Among them, the role of the SETUP request is to negotiate the rtp transmission mode, and TCP and UDP transmission modes are optional. TCP is a connection-oriented protocol. Before sending and receiving data, a reliable connection must be established with the other party. The three handshakes to establish a connection and the four waves to disconnect the connection lay a reliable foundation for data transmission; UDP is a connectionless protocol. Before data transmission, the source and the terminal do not establish a connection. The sender throws the data onto the network as quickly as possible, and the receiver reads the message segment from the message queue.

[0093] 4. After receiving the response from the server in the previous step, the client sends a PLAY request to the server to start playing the media stream output by the set-top box. The PLAY request is a playback request sent by the client, and the playback interval can be specified when sending the playback request.

[0094] See also Figure 6 As shown, the video streaming service provided by the present invention during the communication between the TV and the set-top box is specifically performed as follows:

[0095] Step S21, the user presses the red TV button on the Bluetooth remote control of the U box to activate the U box to enter the one-key screen switching working state, and realize the one-key start video transmission function; (user control step)

[0096] Step S22, the U box calls up the MSIPlayer application on the smart TV; (the system automatically processes step 1)

[0097] Step S23: MSIPlayer on the smart TV initiates a video streaming service request to the MSIServer on the set-top box; (the system automatically processes step 2)

[0098] Step S24: The MSIServer on the set-top box records and encodes the video output of the set-top box in real time, and transmits it to the MSIPlayer on the smart TV via a low-latency protocol. (System automatic processing step 3)

[0099] Step S25: MSIPlayer on the smart TV implements low-latency video stream decoding and screen presentation. (System automatically processes step 4)

[0100] Finally, the user uses the U box remote control to press the "Back" button to return to the TV's built-in content service state. (User control)

[0101] After the TV and the set-top box are connected, the user can control the TV and the set-top box at the same time through the Bluetooth remote control of the U box. The process of the user controlling the TV and the set-top box at the same time through the Bluetooth remote control of the U box is as follows:

[0102] 1. When the user presses the red TV button on the U-box's Bluetooth remote control to open MSIPlayer to present the set-top box content, the user's subsequent operation key values ​​will be automatically transmitted to MSIPlayer through the U-box through the voice channel of the U-box's Bluetooth remote control. MSIPlayer will transmit the user's operation key values ​​to MSIServer through network socket communication and display the operation on the set-top box, so that the purpose of operating the set-top box with the same remote control can be achieved.

[0103] Specifically, the voice channel of the Bluetooth remote control of the U box is the voice button on the Bluetooth remote control. After the user presses the red TV button on the Bluetooth remote control of the U box, the voice channel of the Bluetooth remote control of the U box can be directly and automatically reused to transmit the operation key value of the user's button to MSIPlayer in the user-customized data format. MSIPlayer will transmit the operation key value of the user's button to MSIServer through network socket communication, and finally realize the control of the set-top box.

[0104] Socket is a programming interface used to implement network communication in computer networks. It provides a mechanism that enables applications to send and receive data over the network. In the TCP / IP protocol, socket is an abstract concept located in the transport layer, which is closely related to the TCP and UDP protocols.

[0105] 2. When the user presses the return key (HOME key), it will return to TV mode. The U box's Bluetooth remote control will close the voice channel and transmit the HID standard key value to the TV through the U box to operate the TV.

[0106] For example, the specific streaming media transmission process in the video streaming service is as follows:

[0107] 1. By calling the Android underlying screen recording interface MediaProjection; the Android underlying screen recording interface MediaProjection is a tool class that comes with the Android system and is used for screen recording. It is a software program.

[0108] 2. Record the audio and video content of the set-top box;

[0109] 3. Call MediaCodec to use the codec chip of the set-top box to compress the audio and video, and output the code stream of video H264 encoding + audio AAC encoding;

[0110] 4. Encapsulate the encoded bitstream into a RTSP (Real Time Streaming Protocol) stream that can be transmitted with low latency through the built-in MSI Server streaming media server;

[0111] 5. After the MSIPlayer on the TV side is triggered by one button of the remote control, it finds the corresponding MSIServer in the local area network by using the agreed RTSP handshake protocol and traversing the corresponding routing table data. After authentication, it can pull the recorded video stream for playback.

[0112] It should be noted that MediaProjection is a function that allows an app to capture the screen or record system audio. There are other capabilities depending on the type of MediaProjection. It is enabled through the createScreenCaptureIntent() method of the MediaProjectionManager class, which can be used to capture the screen, but cannot obtain system audio.

[0113] MediaCodec is the codec component in Android, which is used to access the codec provided by the underlying layer. It is usually used with MediaExtractor, MediaSync, MediaMuxer, MediaCrypto, MediaDrm, Image, Surface, and AudioTrack. MediaCodec is almost the standard configuration for hard decoding of Android players, but whether to use a soft codec or a hard decoding codec is related to the configuration of MediaCodec.

[0114] RTSP (Real Time Streaming Protocol) is an application layer protocol proposed by Real Network and Netscape on how to effectively transmit streaming media data on IP networks. RTSP provides an extensible framework that enables controllable, on-demand transmission of real-time data, such as audio streams, video streams, and metadata. It complies with the specifications of IETF RFC 2326, 4567, and 6064. Its syntax and operations refer to HTTP / 1.1. It is a text-based protocol that uses the ISO10646 character set and UTF-8 encoding. The transport layer protocol that carries RTSP is TCP, with the default port 554. If it is RTSP-over-HTTP tunneling, the default TCP port is 8080. Real-time streaming data is transmitted by different protocols, such as RTP / RTCP to complete the transmission of data streams and control commands.

[0115] H264 encoding, also known as Advanced Video Coding (AVC), is a widely used format for recording, compressing and publishing high-precision videos. H264 encoding is a standard format belonging to the encoding layer of video. Video encoding is obviously for compressing size. The standard introduces a series of new technologies that can greatly improve compression performance and can greatly surpass previous standards at both high and low bitrate ends. The core algorithms used by H264 are intra-frame compression and inter-frame compression. Intra-frame compression is an algorithm for generating I frames, and inter-frame compression is an algorithm for generating B frames and P frames. Intra-frame compression is also called spatial compression. When compressing a frame of image, only the data of this frame is considered without considering the redundant information between adjacent frames, which is actually similar to static image compression. Intra-frame compression generally uses a lossy compression algorithm. Since intra-frame compression encodes a complete image, it can be decoded and displayed independently. Intra-frame compression generally does not achieve very high compression, which is similar to encoding JPEG. Inter-frame compression is also called time compression. It compresses data between different frames on the timeline. Inter-frame compression is generally lossless. The frame difference algorithm is a typical time compression method. The data of adjacent frames are highly correlated. It compares the difference between the current frame and the adjacent frames and only records the difference between the current frame and the adjacent frames, which can greatly reduce the amount of data.

[0116] AAC is the abbreviation of Advanced Audio Coding. It is a file compression format designed for sound data. Unlike MP3, it uses a new algorithm for encoding, which is more efficient and has a higher "cost performance". Using the AAC format, people can feel that the sound quality is not significantly reduced, and it is more compact. AAC appeared in 1997 and was originally an audio coding technology based on MPEG-2. It was jointly developed by Fraunhofer IIS, Dolby Laboratories, AT&T, Sony and other companies to replace the MP3 format. In 2000, the MPEG-4 standard was introduced, and AAC reintegrated other technologies (PS, SBR). In order to distinguish it from the traditional MPEG-2AAC, AAC with SBR or PS characteristics is also called MPEG-4AAC.
