Preserving channel lock and performing dynamic ad insertion (DAI) in a multi-device setup

A system, comprising:

• one or more memories;
• and
• at least one processor each coupled to at least one of the memories and configured to perform operations comprising:
• identifying a primary device that performs dynamic ad insertion (DAI) on a channel, and a secondary device that receives the channel from the primary device and is prevented from performing the DAI on the channel based on the primary device performing the DAI on the channel;
• in response to the identification, determining that the primary device is configured to perform the DAI to replace an original portion of multimedia content in the channel with a replacement portion of the multimedia content;
• and
• in response to the determination, transmitting a fingerprint representing the replacement portion of the multimedia content in the channel to the secondary device in place of a fingerprint representing the original portion of the multimedia content in the channel, thereby enabling the secondary device to perform the DAI on the channel.

A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:

• identifying a primary device that performs dynamic ad insertion (DAI) on a channel, and a secondary device that receives the channel from the primary device and is prevented from performing the DAI on the channel based on the primary device performing the DAI on the channel;
• in response to the identification, determining that the primary device is configured to perform the DAI to replace an original portion of multimedia content in the channel with a replacement portion of the multimedia content;
• and
• in response to the determination, transmitting a fingerprint representing the replacement portion of the multimedia content in the channel to the secondary device in place of a fingerprint representing the original portion of the multimedia content in the channel, thereby enabling the secondary device to perform the DAI on the channel.
