Description
Technical Field
The invention belongs to the technical field of intelligent televisions, and relates to an intelligent television interactive service operation system and method based on operation resource sharing.
Background
In recent years, under the background of the development of communication technology, network technology and computer technology, the traditional telecommunication network, computer internet and broadcast network cannot independently meet the increasing business requirements of people, the telecommunication network, the internet and the broadcast network are integrated on a physical level, and the carrier can share network resources to effectively integrate the three traditional networks into a necessary trend of the future network development. Therefore, the smart television plays an important role in a home video service environment due to the fusion characteristics of intellectualization and visibility. Meanwhile, with the increase of the user's demand for video related services, the content carried by the smart television cannot only satisfy the traditional television related services, and the request of the user for more interactive services to the smart television, especially the complex interactive services combined with the video related contents, becomes the main demand for the development of the current smart television services.
Firstly, compared with other intelligent terminals, the smart television is developed slowly in the aspects of updating, upgrading and the like, so that the smart televisions with different operation chips exist in the market, a large difference exists in the aspects of computing capacity, operation environment and the like, and the operation capacity of part of the smart televisions is weak. Secondly, the central processing unit of the smart television and the related display circuit are mainly applied to video stream decoding operation in design and belong to a special service chip, and for complex interactive services in the application process of the smart television, the logic operation of the smart television, especially the calculation support capability under the artificial intelligence service application environment is poor, which causes the problems in the construction of related services.
In the smart tv service environment, compared with other smart mobile terminals, there are several differences in addition to the difference in computing power:
1. in the household network environment, the network connection is more reliable
In a home video service environment, an intelligent mobile (smart phone, tablet computer, etc.) device and an intelligent television are in the same local area network environment (same Wi-Fi network or router), the bandwidth between networks is generally over 100Mbps, the communication capacity between the intelligent mobile device and the intelligent television is strong, and high-speed computing resource transmission can be performed. Under a high-speed network communication environment, computing resources can be conveniently transmitted in a local area network, so that computing can be rapidly transmitted between devices.
2. In the household video environment, the energy supply is convenient and abundant
In a home video environment, the intelligent television adopts a mode of continuously supplying power, and for the intelligent television, the worry in the aspect of energy supply in the application calculation process is avoided; and for the intelligent mobile terminal under the home video service environment, the energy supply environment is sufficient, energy supplement can be conveniently carried out, and compared with the operation unloading related services in the outdoor environment, the energy problem in the operation unloading process can be ignored. Therefore, in the operation unloading application process of the intelligent television, the influence on the energy supply on the aspect of calculating the unloaded energy supply can be ignored.
3. Under the home video environment, the smart television and the mobile terminal conveniently build the environment
In a home video environment, the intelligent television and the intelligent mobile terminal share a common service, and the intelligent television and the intelligent mobile terminal do not have the influence on mutual trust of calculation, so that a trust calculation unloading environment between the intelligent mobile terminal and the intelligent television can be conveniently constructed in the aspect of calculation unloading application.
4. The smart television and the smart mobile terminal present different characteristics in calculation.
The smart television is used as a core video bearing terminal in a home video service environment, is more suitable for decoding application of video streaming media in a hardware architecture environment, and has poor logic operation capability for complex logic operation of other related services, particularly in the complex service environment. For the intelligent mobile terminal, as the main mobile terminal of the current user, the updating of the device is quicker, and the intelligent mobile terminal is more suitable for complex business operation on the framework of the device, so that the role division can be carried out on the business, and the corresponding business unloading is supported.
Based on the analysis of the factors, how to effectively construct the calculation unloading oriented to the intelligent television by means of the network link characteristics of the intelligent television in the home video service environment is a main technical means for solving the problem of insufficient calculation capability of the intelligent television in the interactive operation service. Under the current home video service environment, the smart television is used as a core video service bearing terminal in a home, and particularly, the video quality is gradually upgraded to 4K from standard definition and high definition along with the continuous improvement of the video quality requirement of a user on television content at present. Especially, in the application environment of 4K image quality, for some video operators, in the process of transmitting 4K television programs, a downlink network channel is adopted for program transmission, and this condition will appear in the related interactive services performed in the high-quality video programs performed by the smart television. In the process of downlink data transmission, data blocking occurs.

Detailed Description
The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
1. Establishment of computing resource sharing mechanism
Under the control of different users, the client is influenced by subjective and objective factors to generate selfishness, so that a corresponding incentive mechanism needs to be established to improve the computing resource sharing willingness of the users and ensure the benefit maximization of both the users.
The invention provides a contract-based computing cooperation mechanism on a computing resource sharing incentive mechanism by referring to a data forwarding mechanism of D2D. Firstly, a sending user is taken as a contract consignor, and a contract consignment is provided for idle equipment in the regional network, so that a consignment-proxy contract model is established. In the establishment of the contract relationship, the reward calculation utility function paid by other equipment is used as a reward basis, and meanwhile, the idle user equipment in the regional network environment is matched with the user wishes of a contract consignor and an agent.
In order to reduce the time consumed by relay and route in the process of transmitting data, in the design of a forwarding mechanism of a computing task, an idle client under the same switch is used as a broadcasting object, and a client's entrusting contract can be discovered by an idle user in the communication range of the user through a peer-to-peer network structure of the switch. After the idle user finds the entrusting contract, whether to carry out the proxy request of the contract or not is selected according to the utility function of the idle user.
When the number of idle users in the user communication range is more than that of the user entrusting contract, the idle users feed back the relevant power parameters of the equipment participating in the operation to the entrusting party of the contract for contract bidding, the equipment of the contract entrusting party calculates the corresponding utility function of the entrusting party according to the feedback power value obtained by the equipment of the entrusting party and selects the idle users with the same number as that of the entrusting contract as entrusting objects of the calculation tasks in the multiple entrusting contract bidding according to the utility function, thereby completing the forwarding of the calculation tasks. For an idle user, since there are multiple sending users in the system, the idle user can also participate in competing for multiple contracts at the same time. Thus, the sending user can broadcast the contract to a plurality of idle users, and the idle users can also participate in the competition of the contracts of the plurality of users.
2. Compute cache sharing mechanism
After the intelligent television client performs related calculation, the calculation result is stored in the cache of the client, and the data in the cache is utilized, so that the energy consumption and the calculation efficiency of idle users can be effectively reduced. The invention provides a data sharing network established between intelligent televisions under a local area network environment.
1) Data cache sharing awareness
When the idle equipment in the regional network of the contract entrustment direction carries out contract agent invitation or agent bidding, control interaction information carrying a service number is synchronously transmitted to the local network through the switch, the intelligent television terminal caches the traversing equipment after acquiring the control interaction information, acquires a calculation service block in the cache, returns the number of the calculation service block to the contract entrustment terminal and carries out priority bidding setting. After receiving bidding information of other terminals, the contract entrusting party equipment preferentially selects data in the cache according to the time sequence to share the computing service, and reduces the total computing amount in computing resource sharing.
2) Distributed collaborative caching mechanism
In the design of the cache scheme, the invention adopts a distributed cooperative cache method. In the computing resource sharing service, a contract entrusting party transmits control interaction information to other intelligent television terminals by using a local area network, so that each device in the network spontaneously acquires surrounding information, and determines a cache sharing strategy of the contract entrusting party, thereby being more suitable for the situation of multiple devices in the local area network. Meanwhile, under the condition of a plurality of devices, a certain device determines the caching decision of the device according to the caching condition of the surrounding devices, and the redundancy of the cache is reduced and the cache sharing scheme is optimized by calculating the serial number of the service block as the basis for the cooperative cache.
Examples
In the following, a method for constructing a system in a computing resource sharing environment is described by taking a three-dimensional scene application based on a smart television as an example.
1. Three-dimensional scene rendering interactive operational analysis
In the rendering and interactive operation of the three-dimensional scene, a client needs to receive data of the three-dimensional model through a network and write the model data into a calculation cache of the client. After the client acquires the complete three-dimensional model file data, the client program starts a corresponding process, firstly, the three-dimensional model file in the cache is analyzed according to the packaging protocol of the file, information such as a header file in the three-dimensional model file is acquired, the three-dimensional model is converted into data which can be understood by the program, the data is written into the cache of the client again, and operation preparation is carried out.
In the process of rendering and calculating the three-dimensional scene, a client firstly obtains vertex data of the three-dimensional model. In the cache, the CPU traverses data and calculates to obtain the vertex data of the three-dimensional model, marks the vertex data and writes a new vertex data set into the calculation cache.
After writing the vertices, primitive assembly needs to be done for the vertex data. For the three-dimensional grid model, the primitive assembly aims at constructing the three-dimensional grid by using vertex data and transmitting the three-dimensional grid to image processing equipment of a client side for corresponding rendering calculation.
Firstly, coordinate conversion is carried out on vertex data, the vertex data are converted into screen coordinates, and the conversion result is transmitted to an arithmetic unit of a client side to prepare a primitive assembling process. In the client computing unit, the vertex and the image data machine type fragment are colored through the image processing equipment, and data of the model in aspects of color, material, light, chartlet and the like are processed. And finally, transmitting the calculated result data to a screen for displaying.
In this process, the vertex conversion process is related to the number of vertices, and the larger the number of vertices, the larger the amount of calculation that needs to be performed in the calculation process. Therefore, in the calculation, particularly in the vertex coordinate conversion, material processing, lighting processing, and the like, it is necessary to perform the blocking processing on the three-dimensional model and perform the calculation separately.
2. Block rendering computation of three-dimensional scenes
On a three-dimensional scene rendering computing resource sharing mechanism, a cooperative computing resource sharing service environment needs to be established among a server, an intelligent television client and other intelligent televisions in a local area network, and a three-dimensional scene rendering computing process is completed through the joint action of all terminals.
1) Three-dimensional scene rendering preprocessing
When model data is preprocessed at a server side, firstly, according to the requirements of the size of the model service data, the timeliness of the service and the like, a corresponding service label is adopted as the only mark of the system service; in the process of blocking, numbers are set for all blocks of the model data at the same time, and the combination of the service numbers and the block data labels is used as a unique resource sharing identifier of the block data in the network. And in the service request of the client, the server returns the preprocessed model to the client for rendering calculation.
2) Establishment of contract operation mechanism
After the idle client side joins the contract, the idle client side preliminarily determines that the client side agrees with the current service system of contract mutual-aid operation. In the process of calculation, a local area network is firstly required to provide data service internally. When the intelligent television is in a standby state, the client side obtains the calculation tasks, then carries out calculation, obtains corresponding calculation task rewards, and returns the calculation results to the calculation application side.
When a certain client user obtains the three-dimensional model data of the user, the information such as the current service number information, the data volume calculation description of the calculation service block and the like is obtained through analysis. Meanwhile, the smart television client starts a contract management module to inquire available right resources of the current equipment; and under the condition that the equity resources meet the current service resources, the contract management module performs contract bidding, sends three-dimensional model data rendering contracts to other idle clients in the local area network environment, and waits for the idle clients to perform bidding response.
After receiving the proxy contract, the contract management module of the idle client starts the calculation management module to traverse the cache of the current equipment, judges whether the three-dimensional model rendering cache data matched with the service is stored in the current cache, and then returns the service data cache condition and the calculation power information serving as bidding conditions to the consignor and bidding process of the contract.
After obtaining the bidding information, the contract entrusting party equipment selects proper contract proxy equipment according to the bidding of the idle equipment, the number of the calculation service blocks and the calculation power parameter of the contract entrusting party equipment, writes the equipment information into the cache of the contract entrusting party equipment and prepares for calculation and distribution.
2. Computing distribution process
After the contract bidding is finished, the contract entrusting party starts a calculation management module according to the data information received by the contract agent party, judges a resource sharing mechanism of corresponding contract agent party equipment by taking the number of the calculation service block as a basis, analyzes the bidding data state of the same contract agent party, and performs calculation unloading to the contract agent party through different types of the sharing mechanism.
1) And for the contract agent client side with the cache sharing type, carrying out cache migration on the three-dimensional model rendering data by a distributed cooperative cache sharing method, and storing the three-dimensional model rendering data in a calculation cache of the contract entrustment client side.
2) And for the contract agent client of the calculation sharing type, controlling the computing equipment of the agent client through the calculation management module, performing vertex coordinate conversion and material and light processing calculation on the data of the calculation service block, and transmitting the calculation result back to the client of the client.
After the contract entrustor equipment obtains the rendering calculation data of the three-dimensional model calculation service block, data verification and data integration are carried out through a calculation unit of the contract entrustor equipment, and the interactive and rendering calculation results are transmitted to a user through display equipment, so that the calculation migration process is completed. Meanwhile, in the local cache, the rendering data storing a certain number of computing service blocks is shared, so that the normal operation of acquiring corresponding rights and interests resources in the computing resource sharing service and computing resource sharing circulation is ensured.
As shown in fig. 4, the computing resource sharing process of the system:
firstly, on the initialization establishment of a computing resource sharing process, according to the analysis of interactive services, a method of peer-to-peer partitioning (same computing environment) or service partitioning (same computing resource) is adopted for the interactive services, interactive computation is decomposed into a plurality of interactive computation speeds, and a unique service number is generated in a network.
After acquiring an interactive service request of a user, the interactive preprocessing module performs preliminary screening and analysis on interactive feast data of the user, performs rapid service matching in a service pool of the smart television client, acquires type description of the service and relevant parameters of the service, and establishes a service request data model. And after the service request data model is obtained, transmitting the service request data model to a cache discovery module, and establishing a cache sharing service process.
In the process of cache sharing service, a cache discovery module sends computing resource sharing polling to all intelligent televisions in standby and working states in a local area network according to transmitted interactive computing description and parameters, obtains interactive computing cache data blocks matched with the current service description and the parameters in the current local area network through cache sharing data stored in a sharing service module, and returns the number of the data blocks and corresponding intelligent television routing information to a cache discovery module initiating a request.
The cache discovery module communicates the sharable shared data block number to the calculation management module. And the calculation management module inquires the contract management module, acquires the sharing right mark of the current equipment, determines the quantity of the shared data resources available for the current smart television and determines the sharing strategy. And determining contractors of the contract in the cache discovery module according to the quantity of the shared data resources, and sending cache requests to corresponding intelligent television equipment by responding to the routing information and the service number of the contractors to obtain cache data. After the cache data is obtained and the interactive rendering calculation is completed, the contract management module deducts a corresponding part from the sharing rights and interests of the equipment.
After receiving a shared data polling request of other intelligent televisions in the local area network, the intelligent television acquires interactive service description and interactive parameters, and rapidly traverses the data in the current cache through the cache service module to acquire whether an interactive calculation data block matched with the polling request exists or not; and if the traversal is hit, the network connection information of the corresponding current intelligent television and the identifier of the corresponding interactive service data block are obtained. And performing competitive bidding of the contract.
And after the contract bidding is hit, the cache service module calls the interactive calculation data block matched in the cache and transmits the interactive calculation data block to the intelligent television terminal of the request initiator through the requested network routing information. Meanwhile, the cache service module sends the contract winning information to the contract management module, and the contract management module modifies the current data sharing rights and interests mark of the smart television according to the contract winning information to complete the whole cache sharing business process.
The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and any simple modifications or equivalent substitutions of the technical solutions that can be obviously obtained by those skilled in the art within the technical scope of the present invention are within the scope of the present invention.
