User manual VCON ZAPI DATASHEET

[. . . ] V Z-Kit API (ZAPI) A software development kit allowing customization of interactive, high quality, video and audio solutions on a single chip. The Z-Kit Application Programming Interface (ZAPI) is a set of media library components for integrating VCON's high performance capabilities into applications based on a single chip. [. . . ] Using ZAPI's LAN component, a full videoconferencing client, including VCON's advanced features such as PacketAssistTM, Adaptive Bandwidth Adjustment, Media Xchange ManagerTM and more, may be implemented. Using ZAPI's System component, debugging tools may be added to the application. ­ All in one solution: runs H. 323 protocol stack, H. 263+ encoding and decoding at 30fps, audio encoding and decoding including AEC ­ All on one BSP-15 chip, allowing for rapid development and quick time to market ­ Highly optimized for one or two Equator BSP-15 chips, providing high video quality, low latency and low CPU usage. ­ VCON PacketAssistTM architecture for advanced Quality of Service (QoS) over IP ­ VCON Media Xchange ManagerTM management and scalability module Why ZAPI?­ Complete offering ­ Short time to market ­ Easy to use API ­ 4th IP generation technology ­ H. 263+ codec ­ Support for up to 2 Equator BSP-15 chips ­ Implements H. 323 v4 ­ Includes PacketAssist TM ­ Supports VX Works RTOS Key MXM Features ­ Video call transfer, forward, call pickup ­ Dial plans ­ Call detail records (CDRs) ­ Billing and reporting ­ Policy services ­ QoS services ­ Endpoint configuration ­ Remote call initiation ­ LDAP directory services ­ Gatekeeper functionality ­ Status monitoring Contact us at zapi@vcon. com ZAPI Components The Audio API will start and stop multiple instances of audio encoding and decoding, receive audio from microphone, send audio to speaker and activate Acoustic Echo Cancellation (AEC). The LAN API includes all of the required functionality to build a LAN-based videoconferencing client including support for gatekeepers, gateways, MCU's and VCON MXM. Included in the LAN API is VCON's PacketAssist architecture, bringing advanced QoS to the video application including proprietary networking algorithms that assure the best IP video and audio quality even when used in congested networks. The Video API will start and stop multiple video instances of encoding and decoding, control video encoding parameters and display layout. [. . . ] VCON's Z-Kit allows for custom development and integration of videoconferencing into a variety of form factors. V ZAPI To obtain a ZAPI evaluation kit, please contact us at zapi@vcon. com.
