DIGITAL CONTENT STREAMING FROM DIGITAL TV BROADCAST

摘要

Techniques are described for remuxing multimedia content received in a digital video broadcasting format without performing transcoding of the video and/or audio content. For example, a computing device with a digital television tuner can receive multimedia content in a digital video broadcast format. The computing device can remux the received multimedia content from the digital video broadcasting format in which the multimedia content is received into a target streaming protocol for streaming to other devices. Remuxing operations can comprise demultiplexing the received multimedia content to separate the audio and video content, performing meta-data reconstruction, and multiplexing the audio and video content into a target stream using a target streaming protocol format.

主权项

1. A computing device comprising:
a processing unit; memory; and an antenna configured for receiving digital video broadcast television signals; the processing unit configured to perform operations for remuxing multimedia content, the operations comprising:
receiving, via the antenna, the multimedia content in a digital video broadcasting format, the multimedia content comprising audio content and video content;determining a target streaming protocol;demultiplexing the multimedia content in the digital video broadcasting format to separate the audio content and the video content;for the video content:
performing meta-data reconstruction for the video content based, at least in part, on the target streaming protocol; andmultiplexing the video content in a target stream according to the target streaming protocol using the reconstructed meta-data and without transcoding the video content;for the audio content:
when an audio coding format of the audio content is compatible with a target computing device, multiplexing the audio content in the target stream according to the target streaming protocol without transcoding the audio content; andotherwise, when the audio coding format of the audio content is not compatible with the target computing device, transcoding the audio content to a different audio coding format for multiplexing in the target stream according to the target streaming protocol; andproviding the target stream according to the target streaming protocol for streaming to the target computing device.
