BROADCAST MIDDLEWARE, BROADCAST TERMINAL, BROADCAST SERVER DEVICE AND BROADCAST COMMUNICATION METHOD

摘要

Provided are broadcast middleware, a broadcast terminal, a broadcast server device and a broadcast communication method. The broadcast middleware is applied to a broadcast receiver side and is used for establishing a bidirectional channel between a broadcast receiver and a broadcast server, and comprises a presentation layer module, a transmission control layer module and a physical layer module which are connected in sequence, wherein the presentation layer module is responsible for broadcasting service logic; the transmission control layer module is responsible for the transmission control of the bidirectional channel; and the physical layer module is used for sending an uplink data frame to a broadcast server side via the connected network or receiving a downlink data frame sent by the broadcast server side. The present application can expand the implementation manner of a broadcast bidirectional channel and the range of a broadcast bidirectional terminal.
