1. A and B are APIs between middleware and upper layer applications. 2. Interface A: This is a callback interface of Java Script. Through this interface, the EPG system exchanges information with STB applications. 3. Interface B: This is the media stream transmission and control interface. Through this interface, STB applications control the interaction with the media server, set up/disconnect sessions, receive media, and play control. © ZTE Corporation. All rights reserved
