Methods and systems to fast fill media players
View Patent ↗Methods and systems are provided to fast fill media players and buffers associated with media players. A bandwidth associated with initial startup of a media player is overloaded to rapidly fill the buffer and initiate the media player. Alternatively, multiple simultaneous data communication sessions are established with a media data source device, and the media data are concurrently received from the simultaneous sessions into the buffer or transferred of out the buffer at startup, thereby decreasing the latency associated with initiating the media player.
1. A method of filling a media player residing in a non-transitory computer-readable storage medium and for execution on a machine, comprising:
determining, by a media player executing on the machine, a connection bandwidth and a latency threshold for use in requesting media data, the connection bandwidth indicating a bandwidth that is to be used when delivering the media data to the media player;
generating a set of data communication requests, each data communication request of the set of data communication requests configured to request a portion of the media data from a media source, the set of data communication requests being configured to be executed concurrently;
estimating a duration of executing the set of data communication requests concurrently;
determining that the estimated duration of executing the set of data communication requests exceeds the latency threshold;
in response to determining that the estimated duration of executing the set of data communication requests exceeds the latency threshold:
identifying a quantity of additional data communication requests to be added to the set of data communication requests based on the estimated duration of executing the set of data communication requests; and
updating the set of data communication requests to include the quantity of additional data communication requests;
initiating, by the machine, execution of the updated set of data communication requests, wherein execution of each data communication request of the updated set of data communication requests triggers establishing a transfer session with the media source that is configured to transfer the portion of the media data corresponding to the data communication request;
estimating a combined bandwidth corresponding to supporting transfer sessions for each of the updated set of data communication requests;
determining that the estimated combined bandwidth exceeds a processing rate of the media player;
in response to determining that the estimated combined bandwidth exceeds the processing rate, increasing, by the machine, the processing rate of the media player to a new processing rate;
receiving, by the machine and via processing of the media player at the new processing rate, multiple portions of the media data into a single buffer associated with the media player, the multiple portions corresponding to multiple data communication requests of the updated set of data communication requests;
determining, by the machine and prior to having stored all portions corresponding to all of the updated set of data communication requests in the single buffer, that the single buffer is full; and
in response to determining that the single buffer is full, initiating, by the machine, playback of the media data by the media player, wherein initiation of the media player causes one or more of the multiple portions of the media data in the single buffer to be removed from the single buffer and played by the media player.

6. The method of claim 1 , wherein multiple portions of the media data are received using a bandwidth that exceeds the connection bandwidth.
7. The method of claim 1 , wherein receiving multiple portions of the media data into a single buffer associated with the media player comprises:
filling a remaining capacity of the single buffer with duplicate copies of the multiple portions of the media data until the single buffer is full, wherein one or more additional portions of the media data are received and replace the duplicate copies before the media player obtains the duplicate copies.
