CPC Class H04N

Techniques are described for managing synchronized jitter buffers for streaming data (e.g., for real-time audio and/or video communications). A separate jitter buffer can be maintained for each codec. For example, as data is received in network packets, the data is added to the jitter buffer corresponding to the codec that is associated with the received data. When data needs to be read, the same amount of data is read from each of the jitter buffers. In other words, at each instance where data needs to be obtained (e.g., for decoding and playback), the same amount of data is obtained from each of the jitter buffers. In addition, the multiple jitter buffers use the same playout timestamp that is synchronized across the multiple of jitter buffers.

Disclosed embodiments include systems and methods for distributed control of media-playback components of a webcast. In an example, a webcast presenter's device can include a webcast compositing engine for creating a webcast from a variety of data sources, a media-playback engine for playing media content items, and a message processing engine for processing messages sent from audience members to the presenter. The message processing engine can obtain the messages and parse the messages for tokens indicative of a requested media content item. The message processing engine, having identified the requested media content item, can then cause the media-playback engine to play the requested content or add it to a queue.

Provided are a conference access method and a terminal for performing the same. A terminal according to an embodiment of the present disclosure includes: an interface configured to receive a plurality of different access addresses for access to a conference from a conference server; an access attempter configured to attempt to simultaneously access the conference via each of the plurality of access addresses; and a priority allocator configured to collect an access result for each of the plurality of access addresses, and to allocate an access priority to each of the plurality of access addresses based on the access result, wherein the access attempter attempts to access the conference via an access address having a highest access priority among the plurality of access addresses.
