Editor's Notes
- #9 In most commercial use cases a client should support SIP and H.323 Call control (telephony logic)Integration and synchronization of Signaling and Media Both SIP and H.323 include a large amount of different scenarios and configurations
- #10 Multi protocolsinteroperabilityH.323 and SIPInteroperability with as many endpoints from the marketSupport in non standard implementations done by other vendors Requires hundreds of test cases and scenarios Error handling mechanism with none standard endpoints Codecs interoperabilityMany different codecs headers need to be supportedEvery codec involves different behavior Complex configuration need to be supported Support different media configurationsFor each codec many different configurations are required Multiple interoperability test cases
- #11 Overcome network impairments Jitter buffer FECAudio and Video synchronization MechanismBandwidth management – real-time adaptation of resolution and frame rate according to available network bandwidthRTCP support (different codecs)
- #12 Video Engine:Development of specific H.264 codec optimized for specific platform (i.e. TI DM6467 using TI’s internal Accelerators)Multi slicing (There is NO off-the-shelf codec supporting multi slicing which requires building a codec from scratch)Dual video support (720p video encodingdecoding and PNC 1080p Encoder) H.263 integration & Optimization for interoperability Audio Engine:Codecs run and optimized to run on DSP (G.711, G.723.1, G.722, G.729)
- #13 Drivers: Camera Drivers – requires specific configuration and settingsUSB driver for both sides (not included in TI SDK) – need to support USB host and USB deviceAudio drivers and Acoustic Echo cancellation DSP and ARM integration and optimizationOperating System integrationBootloaderHW accelerators integration and codecs optimization
- #14 Distributed software integration (i.e. running on 2 TI DaVinci) Requires USB drivers (host and Client) Divide the application to allow running different modules on Master and SlaveOptimization of application flow and data flowSystem level integration & TestingComplete system workload Hundreds of test cases for each module and system test
- #15 Allow remote management of all endpointRemote software upgrade SNMP MIB for configuration and alarmsOpen API’sIntegration to Management Server (i.e. iView)
- #21 Complete Desktop Client engine:Multi protocol support (SIP, H.323) Media Control and Codecs Superior video and audio qualityOptimized for Desktop PC Telephony services:Telephony services (Call, Caller ID, N-Way Calls, Multi-line support) Simple integration (high level APIs , easy to use)Supplementary services (Call Hold, Mute, Transfer, Forward, Call Waiting) Pre-integrated with Hardware platform:BEEHD provide optimized solution for Intel base platforms (Desktop) Short integration time with peripherals (Camera, speakers, microphone) IM/Presence Service module:Standard-based instant messaging protocol (MSRP)Interoperability with other instant messagesStandard-based Presence protocol (SIMPLE, XDM)Service module that handles all Presence and IM application APIs
