Methods and Apparatus for Distributing and Acquiring Overhead Flow Data in a Multi-Frequency Network
摘要:
Methods and apparatus for distributing and acquiring overhead flow data in a multi-frequency network. In an aspect, a method includes generating initial acquisition flows (IAFs) that describe how content multiplexes are distributed in the multi-frequency network and provide flow identifiers for overhead flows associated with the content multiplexes, and transmitting the IAFs on pre-assigned flow identifiers. Another method includes receiving IAFs that describe how content multiplexes are distributed in the multi-frequency network and specify flow identifiers for overhead flows associated with the content multiplexes, wherein the IAFs are received using pre-assigned flow identifiers, processing the IAFs to determine VM sets associated with current wide and local areas of the multi-frequency network, determining overhead flow related information associated with selected content multiplexes in the VM sets, and acquiring overhead flow data associated with the selected content multiplexes using the associated flow identifiers.
