Description

Technical Field

[0001] This invention relates to the field of broadcasting and television technology, and more specifically, to a multi-channel television content transmission system for triple play (telecommunications, broadcasting, and internet convergence). Background Technology

[0002] With the deepening of the three-network convergence strategy, the boundaries between broadcast television networks, telecommunications networks, and the Internet are becoming increasingly blurred. Users' demand for television services has evolved from traditional one-way viewing to interactive, personalized, and diversified directions. As the core entry point for home entertainment and information consumption, the large television screen is gradually taking on comprehensive functions such as content distribution, social interaction, video shopping, and other value-added services.

[0003] Traditional broadcast television networks possess advantages such as wide coverage, stable transmission, and low cost, especially in achieving large-scale, synchronous information dissemination, where they hold an irreplaceable advantage. However, their unidirectional transmission characteristic limits users' ability to engage in personalized, two-way real-time interaction. On the other hand, telecommunications networks and the internet offer rich two-way interactive capabilities, supporting personalized services such as on-demand viewing, replay, and online shopping. However, achieving precise synchronous triggering of massive numbers of terminals at the same moment—for example, conducting public voting, real-time quizzes, or flash sales during live television broadcasts—relying solely on IP networks for trigger signal transmission would face enormous network bandwidth pressure, inconsistent transmission latency, and system stability risks. This high-concurrency triggering mechanism not only increases the burden on servers and network equipment but also makes it difficult to guarantee that all users receive uniform interactive commands within milliseconds, impacting user experience and the fairness of interaction. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a multi-channel television content transmission system for triple play, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-channel television content transmission system for triple play, comprising a broadcast beacon generation and insertion module, a television terminal, an interactive module, and a beacon resource mapping and scheduling module;

[0006] The broadcast beacon generation and insertion module is used to receive interactive service triggering instructions, generate lightweight interactive beacon data, and insert the interactive beacon data into the broadcast television signal stream to be broadcast.

[0007] The television terminal includes a beacon parsing and synchronization triggering unit, which receives the broadcast television signal stream, parses the interactive beacon data contained therein, and triggers the television terminal to establish an IP communication connection with the interactive module based on the parsed interactive beacon data.

[0008] The interactive module establishes a two-way IP communication connection with the TV terminal via the Internet, and provides personalized interactive services based on interactive beacon data and requests sent by the TV terminal.

[0009] The beacon resource mapping and scheduling module is connected to the broadcast beacon generation and insertion module and the interaction module, respectively. It is used to store the mapping relationship between interactive beacon data and corresponding interactive resources, and to schedule the resources of the interaction module.

[0010] Preferably, as a preferred embodiment of the multi-channel television content transmission system for triple-play convergence described in this invention, it includes a broadcast beacon generation and insertion module for receiving interactive service trigger commands, generating lightweight interactive beacon data, and inserting the interactive beacon data into the broadcast television signal stream to be broadcast, specifically including the following:

Interactive types Location information of IP-side interactive resources Interactive effective time range, preset prompt text Its structure is defined as ,in, and These represent the valid start and end times of the interaction, respectively.

[0012] Based on the received interactive service trigger instruction, perform the following: The data packets are parsed, formatted, and compressed to generate structured interactive beacon data with a very small data volume, and then encapsulated into interactive beacon data packets. It is transmitted through the data broadcast channel in the digital television standard and inserted into the currently broadcast television signal stream.

[0013] Preferably, as a preferred embodiment of the multi-channel television content transmission system for triple-play convergence described in this invention, the television terminal includes a beacon parsing and synchronization triggering unit, which receives the broadcast television signal stream, parses the interactive beacon data contained therein, and triggers the television terminal to establish an IP communication connection with the interactive module based on the parsed interactive beacon data. Specifically, it includes the following:

[0014] The radio frequency tuner and demodulator built into the TV terminal are used to receive the broadcast TV signal stream, convert it into a digital baseband signal, and then demultiplex the digital baseband signal to demultiplex the MPEG-2 transport stream, separating the video stream, audio stream and various data streams, including the data broadcast stream carrying interactive beacon data.

[0015] The beacon resolution and synchronization triggering unit extracts all interactive beacon data packets from the demultiplexed data stream, decapsulates the extracted data packets, and restores the original beacon data packets. and to The data payload is decompressed to restore the formatted interactive information. Cyclic redundancy check is performed on the decapsulated beacon data to ensure that no errors occur during data transmission.

[0016] The verified beacon data is parsed to extract key information, including the unique identifier of the interactive event, the interaction type, the location information of the IP-side interactive resources, the effective time range of the interaction, and the preset prompt text. The program playback time within the TV terminal is monitored and compared with the start time of the parsed beacon data. and end time A comparison was performed, and the current time falls within the valid interaction time range defined by the beacon.

[0018] When the TV terminal receives a user's instruction to participate in the interaction, it sends a request to the beacon resource mapping and scheduling module via the IP network to obtain the final resources, establishes a two-way communication connection with the interaction module, requests complete personalized interactive content, and prepares to upload user interaction data. The request carries the location information of the IP-side interactive resources parsed from the beacon, as well as a unique identifier for the interactive event.

[0019] Preferably, as a preferred embodiment of the multi-channel television content transmission system for triple-play convergence described in this invention, the interactive module establishes a two-way IP communication connection with the television terminal via the Internet, and provides personalized interactive services based on interactive beacon data and requests sent by the television terminal, specifically including the following:

[0020] By deploying a load balancing cluster to access IP communication connection requests from TV terminals, the validity of each connection resolution request is verified by the unique identifier of the interactive event and the location information of the IP-side interactive resources. After the request is verified, an interactive session is established for the verified terminal and a unique session identifier is assigned to track and manage the status of the terminal throughout the interaction process. The interactive session is strongly associated with the event ID in the broadcast beacon.

When a flash sale request is received, it deducts the inventory using an atomic decrement operation. By executing the atomic operation of "verifying inventory and deducting," the flash sale is considered successful only if the inventory value is non-negative after the operation; otherwise, it immediately returns failure. After a successful flash sale, a pending order record is generated and placed in a message queue for asynchronous persistence and subsequent processing by the downstream order service.

It is used to store the mapping relationship between interactive beacon data and corresponding interactive resources, and to schedule the resources of the interaction module. Specifically, it includes the following:

Generate a unique key and record the voting status of the terminal in a distributed cache to prevent the same terminal from voting repeatedly within the validity period; The flash sale service processing unit pre-loads the inventory of the flash sale item into a distributed cache. When a flash sale request is received, it deducts the inventory using an atomic decrement operation. By executing the atomic operation of "verifying inventory and deducting," the flash sale is considered successful only if the inventory value is non-negative after the operation; otherwise, it immediately returns failure. After a successful flash sale, a pending order record is generated and placed in a message queue for asynchronous persistence and subsequent processing by the downstream order service. Based on terminal IP address information, strict request frequency limits are implemented to prevent malicious order placement. User lottery service processing unit: According to Load the corresponding prize pool configuration from the resource library, including the total number of prizes and the winning probability of each prize. When a lottery request is received, calculate the winning results according to the discrete random sampling algorithm, record the winning information, and trigger the subsequent prize distribution process through the message queue. S4. Based on the business logic processing results of step S3, and combined with the interactive content data retrieved from step S1, assemble a personalized response data packet for the current terminal, and send the personalized response data packet to the requesting TV terminal through the established IP connection to drive the execution of the interactive interface on the TV screen.
