Abstract: A method implemented in an electronic device serving as an orchestrator managing video and audio stream processing of a streaming platform system is disclosed. The method includes the electronic device receiving a request to process a video source and creating a task graph based on the request, where the task graph is a directed acyclic graph of tasks for processing the video source, where each node of the task graph represents a processing task, and where each edge of the task graph represents a data flow across two processing tasks and corresponding input and output of each processing task. The method also includes the electronic device estimating resource requirements of each processing tasks, and splitting the task graph into a plurality of subsets, wherein each subset corresponds to a task group to be executed by one or more workers of a plurality of processing units of the streaming platform system.

Block-based communication in a communication services patterns environment
Michel K. Bowman-Amuah
- 31 Aug 1999
TL;DR: In this paper, a system and method for transmitting data from a server to a client via blocks is described, where a user query for a solution set is transmitted to a server, which is then used to query a database for a first subset of the solution set, and when a second request from the client for the data in the database of the server is received, a second block of the data sets is queried from the database, built and then transmitted to the client over the network.
