About: Digital subchannel

An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called "multicasting".

dbo:abstract
  • In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called "multicasting". (en)
  • En radiodifusión, un subcanal digital representa a cada uno de los programas independientes que son transmitidos al mismo tiempo desde una estación de Radio Digital Terrestre o televisión digital terrestre en el mismo canal de radiofrecuencia. Esto se hace mediante el uso de técnicas de compresión de datos que reducen el tamaño de cada flujo de programa individual, y multiplexación para combinarlos en una sola señal. Esta práctica es a veces denominada multicasting. (es)
  • 数字子频道（英語：Digital subchannel）是指在广播上，从同一个数字广播电台或地面数字电视台站所发射的同一个射频频道上同时搭载一个以上独立节目流的技术。这是通过数据压缩技术来减小每个独立节目流的大小，再采用的方式将它们组合成单个的信号流。这种技术有时也被称为“组播技术”。 (zh)
