Embodiments of this application disclose a synchronization method and a device. A device marks, based on a preset period, a periodic code block in a data bitstream to be sent from a MAC layer to a PHY layer. The device sends the data bitstream to a peer device through the PHY layer, records a sending time of each periodic code block as a first timestamp during sending, and returns the first timestamp to the MAC layer. By marking a timestamp for the periodic code block received from the MAC layer, the device sets a PHY-layer-based time reference scale (namely, the first timestamp) at the PHY layer.

Synchronization method and device

Embodiments of the present invention provide method, system and apparatus for playing advertisements during buffering time in network living broadcasting. The method includes: obtaining, by a network living broadcasting client, streaming media data of a channel currently watched by a user, obtaining an advertisement content file corresponding to the channel, triggering to play the advertisement content file; stopping play the advertisement content file when the amount of the streaming media data retrieved by the network living broadcasting client reaches a pre-determined quantity, and starting to play the streaming media data retrieved. The system includes an advertisement server and a network living broadcasting client.
