印度的无线频谱从基站转向手机：从DTT到D2MIndia’s Airwaves Shift From Towers To Phones: DTT To D2M
➀ 印度正在从模拟广播向数字广播过渡，DTT（数字地面电视）取代了模拟发射器。DTT 标准使用 VHF/UHF 载波进行数字传输。
➁ 随着移动设备成为视频消费的主要媒介，智能手机中集成了 DTT 接收器的概念逐渐兴起。这催生了 D2M（直接到移动设备）的概念，将移动基站广播与 DTT 结合起来。
➂ 在没有立即推出 D2M 替代方案的情况下关闭 DTT 发射器导致对付费服务（如 DTH 和 OTT）的依赖增加。D2M 的引入延迟影响了公共广播并增加了互联网带宽的使用。
➀ India is transitioning from analogue to digital broadcasting, with DTT (Digital Terrestrial Television) replacing analogue transmitters. The DTT standard uses VHF/UHF carriers for digital transmission.
➁ Mobile phones are increasingly becoming the primary medium for video consumption, prompting the integration of DTT receivers into smartphones. This has led to the concept of D2M (Direct-to-Mobile), which combines mobile tower broadcasts with DTT.
➂ The shutdown of DTT transmitters without immediate D2M alternatives has led to a reliance on paid services like DTH and OTT. The introduction of D2M remains delayed, impacting public broadcasting and increasing internet bandwidth usage.
