Providing multiple ABR streams using a single transcoder

摘要

An device and method for providing multiple adaptive bit rate (ABR) streams using a single transcoder is disclosed. The device receives a group of content segments for a media channel, and converts, using a transcoder, a first of the content segments from a source format to a first data format, a first time duration for converting the first content segment being less than a second time duration for receiving each group of segments. The converted segment is then sent to a client device. On receiving a request from the device for content segments in a second data format, the device performs an initialization of the transcoder to convert content segments from the source format to the second data format, the initialization being completed during a residual period of time, or “operational gap” produced by a difference between the first time duration and the second time duration.

主权项

1. A method for providing multiple adaptive bit rate (ABR) profiles for a content stream using a single transcoder, comprising:
receiving a group of content segments for a media channel; converting, by a transcoder device, a first content segment of the group of content segments from a source format to a first data format, a first time duration for converting the first content segment being less than a second time duration for receiving each content segment in the group of content segments; providing the converted first content segment to a client device; in response to receiving a request for content segments in a second data format, initializing the transcoder device to convert a second content segment of the group of content segments from the source format to the second data format, the initializing being completed during a residual period of time produced by a difference between the first time duration and the second time duration; and providing a converted second content segment to the client device.
