【摘要】 随着网络技术和智能终端设备的普及,映客、花椒、斗鱼等直播平台不断涌现。移动直播开始兴起,也标志着全民直播时代的到来。作者所在的字节跳动直播团队也在2019年开始发力直播领域,推出了抖音直播、头条直播等,并在近几年快速发展。而作为直播的核心,直播营收系统也应运诞生。目前直播的主要营收方式为观众进行送礼打赏,主播与平台对打赏金额进行分成的模式。直播打赏的全链路即为营收的核心,整个链路包含了礼物模块、充值模块以及激励用户打赏的兑换模块。这些模块在风险控制系统的护航下,构成了直播营收系统的总体,并不断更新迭代。直播营收系统在作者参与之前有礼物模块和充值模块两大部分,作者参与了兑换模块从无到有的整个开发过程,并对充值模块中接入风险控制系统,接入充值套餐推荐算法进行了开发。并参与了礼物模块的日常迭代与优化。具体来讲,作者在整个系统中主要负责的地方有:(1)独立完成了兑换模块安卓端的总体设计、详细设计、开发与部分测试工作,作为主要开发人员,主导协作完成充值模块、风控模块的开发与设计工作。参与礼物模块的需求迭代与开发。(2)在兑换模块、充值模块、风控模块以及部分礼物模块的产品初评方案基础上,参与对需求的详细分析评审,进行各个模块产品的逻辑细节梳理以及交互设计评价。(3)主导并制定了营收充值和兑换模块的总体架构方案,设计了各类套餐方案以及各模块之间的交互接口。设计并确定了与后端之间的接口方案、对应的数据结构以及接口的请求时机。(4)对测试用例进行完善和补充,参加对测试用例的评审,独立完成P0级别用例测试。(5)参加了充值套餐推荐数据集的建设以及接入充值套餐推荐算法。进行安卓端风险控制模块开发,并参与风控系统中评分模型的数据搭建与设计。经过实际的上线与实验验证,直播营收系统在抖音直播、火山直播等平台效果明显,提高了用户的看播时长,也为主播和平台带来收益,实现直播生态的良性发展。更多还原

【Abstract】 With the popularization of network technology and intelligent terminal equipment,live broadcast platforms such as Inke,Huajiao,and Douyu continue to emerge.This also indicates that the era of national live broadcasting is coming.The author’s department-Byte Dance live broadcast team,also began to develop the live broadcast field in 2019,launching Douyin live broadcast,Toutiao live broadcast,etc.And these Apps has developed rapidly in recent years.As the core of live broadcast,the live broadcast revenue system was also born.At present,the audience gives gifts to the anchor as the main path of revenue,and the mode of sharing the reward amount between the anchor and the platform.The whole path of live rewarding is the core of revenue.The whole revenue path includes a gift module,a recharge module,and a exchange module that motivates users to send gift.Under the escort of the risk control system,these modules constitute the overall live broadcast revenue system,and are constantly updated and iterated.Before the author participates in the live broadcast revenue system development,there are only two parts: the gift module and the recharge module.The author participated in the entire development process of the exchange module from scratch,lead the risk control system and the recharge package recommendation algorithm development.In addition,author also participated in the daily iteration and optimization of the gift module.Specifically,the author is mainly responsible for the following in the whole system:(1)Independently completed the overall design,detailed design,development and partial testing of the Android terminal of the exchange module.As the main developer,author led and collaborated to complete the development and design of the recharge module and risk control module.Participated in the requirement iteration and development of the gift module.(2)Participated in the demand analysis of exchange module,recharge module,risk control module and some gift modules,sorted out the logical details of each module product and evaluated the interaction design..(3)Leading and formulating the overall architecture plan of the recharge and exchange modules,designing various package plans and the interactive interface between each module.Design and determine the data structure,interface scheme and request timing for interaction with the backend.(4)Participate in the review of test cases,supplement and improve test cases,and independently complete P0 level test cases.(5)Participated in the construction of the recharge package recommendation data set and access to the recharge package recommendation algorithm.Carry out the development of Android risk control module,and participate in the data construction and design of the scoring model in the risk control system.After launch and experimental verification,the live broadcast revenue system has obvious effects on platforms such as Douyin live broadcast and Volcano live broadcast,which improves the user’s watching time,also brings benefits to the anchor and the platform,and realizes the healthy development of the live broadcast ecosystem.更多还原
