Synchronized Source Selection for Adaptive Bitrate (ABR) Encoders

A method comprising:

• producing, from a first source by a first device, a first adaptive transport stream (ATS) that is aligned with a second ATS produced by a second device, the first device being fed from the first source;
• switching the first device from being fed from the first source to being fed from a second source;
• receiving an indication that the second device cannot be switched from being fed from the first source to being fed from the second source;
• determining that the second source is lower in priority than the first source;
• and
• muting the first ATS in response to receiving the indication and in response to determining that the second source is lower in priority than the first source.

A system comprising:

• a memory storage;
• and
• a processing unit disposed in a first device coupled to the memory storage, wherein the processing unit is operative to:
• produce, from a first source, a first adaptive transport stream (ATS) that is aligned with a second ATS produced by a second device, the first device being fed from the first source;
• receive an indication that the second device switched from being fed from the first source to being fed from a second source;
• switch, in response to receiving the indication, the first device from being fed from the first source to being fed from the second source;
• and
• produce, from the second source, the first ATS that is aligned with the second ATS produced by the second device.
