Digital Broadcasting(数字广播)研究综述
Digital Broadcasting 数字广播 - Planning for Multi-Frequency Network (MFN) with Digital Video Broadcasting-Second Generation Terrestrial (DVB-T2) services is particularly useful during the transition from analog to digital broadcasting. [1] The DTT spectrum band ranges from 470 – 694 MHz in Tanzania after successfully migrating from analogue to digital broadcasting. [2] How are the current law maps of analog and digital broadcasting in Indonesia? How is the current practice of digital broadcast media business in Indonesia? The type of research is descriptive. [3] OFDM is a multi-carrier modulation method with a single antenna configuration, which is very much common in modern cellular networks for digital broadcasting, audio streaming, and 4G mobile communications. [4] The future development and research directions of digital broadcasting and multimedia systems are also discussed. [5] The National Broadcasting Commission’s (NBC) deadline for broadcast stations in Nigeria to switch from analogue to digital broadcasting has spurred the Ministries of Information and Communications, other regulating agencies and the broadcasting industry to be working round the clock to actualize the objective. [6] The rapid development of information technologies, new media: the blogosphere, social networks, the transition to digital broadcasting in the 21st century, has made it necessary to understand the cultural and information processes in Kazakhstan. [7] Video data watermarking becomes very essential due to digital broadcasting. [8] This study uses a text-based qualitative method with interviews as a data collection technique to show the phenomenon of Social TV IG TV being the impact of digital broadcasting. [9] The rapid development of information technologies, new media: the blogosphere, social networks, the transition to digital broadcasting in the 21st century, has made it necessary to understand the cultural and information processes in Kazakhstan. [10]规划具有数字视频广播-第二代地面 (DVB-T2) 服务的多频网络 (MFN) 在从模拟广播到数字广播的过渡期间特别有用。 [1] 在成功从模拟广播迁移到数字广播之后，坦桑尼亚的 DTT 频谱范围为 470 – 694 MHz。 [2] 印度尼西亚现行的模拟和数字广播法律地图如何？印尼数字广播媒体业务的现状如何？研究类型是描述性的。 [3] OFDM 是一种具有单天线配置的多载波调制方法，在用于数字广播、音频流和 4G 移动通信的现代蜂窝网络中非常常见。 [4] 还讨论了数字广播和多媒体系统的未来发展和研究方向。 [5] 国家广播委员会 (NBC) 规定尼日利亚广播电台从模拟广播转向数字广播的最后期限已促使信息和通信部、其他监管机构和广播行业日以继夜地工作以实现这一目标。 [6] 信息技术、新媒体的快速发展：博客圈、社交网络以及 21 世纪向数字广播的过渡，使得了解哈萨克斯坦的文化和信息进程成为必要。 [7] 由于数字广播，视频数据水印变得非常重要。 [8] 本研究使用基于文本的定性方法和访谈作为数据收集技术，以展示社交电视 IG TV 受到数字广播影响的现象。 [9] 信息技术、新媒体的快速发展：博客圈、社交网络以及 21 世纪向数字广播的过渡，使得了解哈萨克斯坦的文化和信息进程成为必要。 [10]

The UL is fully compatible with the Integrated Services Digital Broadcasting Terrestrial Version B (ISDBTB). [1] The scheme that combines ISDB-T (Integrated Service Digital Broadcasting - Terrestrial) and LDM (Layered Division Multiplexing) has been proposed as the way to shift to the next-generation DTTB (Digital Terrestrial Television Broadcasting). [2] Integrated Services Digital Broadcasting-Terrestrial/Satellite (ISDB-T/S) signal, used in Japan as the digital television (TV) broadcasting standard, is exploited in this paper for passive bistatic radar two-dimensional imaging of stationary targets. [3] In this work, a transmission system inherited Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) has been developed, which can provide both fixed reception service and mobile reception service. [4] In the integrated services digital broadcasting-terrestrial (ISDB-T) system, the combination of digital terrestrial transmission and MPEG-4 advanced video coding (MPEG-4 AVC) has offered ways to provide a variety of digital high-definition television (HDTV) programs. [5] Integrated Services Digital Broadcasting Terrestrial (ISDB-T) is the standard adopted in Ecuador since 2010. [6] Our objective is to evaluate the effect of Nakagami-Rice fading on γand $N$ for the Integrated Services Digital Broadcasting - Terrestrial (ISDB-T) service. [7] In the Digital Terrestrial Television System ISDB-T (Integrated Services Digital Broadcasting Terrestrial), it is specified how to send emergency information by the Emergency Descriptor EWBS (Emergency Warning Broadcast System) of Table PMT (Program Map Table); The emergency information is restricted to 1 bit with status of (activation/No -activation) and the area code that determines the geographic location where the alert or alarm will be activated. [8] Then 8k FFT/IFFT is used and number of sub-carriers are 5617 such as mode3 in Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) spec. [9] In Japan, the next generation of the Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) system is being developed to transmit large-volume content services such as ultra-high definition television (UHDTV). [10] In the Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) digital television standard, the emergency wake-up procedure is called an Emergency Warning System (EWS). [11]UL 与综合业务数字广播地面版本 B (ISDBTB) 完全兼容。 [1] nan [2] 综合业务数字广播 - 地面/卫星 (ISDB-T/S) 信号在日本用作数字电视 (TV) 广播标准，在本文中被用于静止目标的无源双基地雷达二维成像。 [3] 在这项工作中，开发了一种继承了综合业务数字广播-地面（ISDB-T）的传输系统，它可以提供固定接收服务和移动接收服务。 [4] 在综合业务数字地面广播（ISDB-T）系统中，数字地面传输与MPEG-4高级视频编码（MPEG-4 AVC）的结合为提供多种数字高清电视（HDTV）提供了途径。程式。 [5] 综合服务数字地面广播 (ISDB-T) 是厄瓜多尔自 2010 年以来采用的标准。 [6] 我们的目标是评估 Nakagami-Rice 衰落对综合服务数字广播 - 地面 (ISDB-T) 服务的 γ 和 $N$ 的影响。 [7] 在数字地面电视系统ISDB-T（Integrated Services Digital Broadcasting Terrestrial）中，通过表PMT（节目映射表）的Emergency Descriptor EWBS（Emergency Warning Broadcast System）规定了如何发送紧急信息；紧急信息被限制为 1 位，状态为（激活/未激活）和确定警报或警报将被激活的地理位置的区号。 [8] 然后使用 8k FFT/IFFT，子载波数为 5617，例如综合业务数字地面广播 (ISDB-T) 规范中的模式 3。 [9] 在日本，正在开发下一代综合业务数字地面广播 (ISDB-T) 系统，以传输超高清电视 (UHDTV) 等大容量内容服务。 [10] 在综合业务数字地面广播 (ISDB-T) 数字电视标准中，紧急唤醒程序称为紧急警报系统 (EWS)。 [11]
