VideoRTSP

Establishes the video sessionControls single or several continuous streamsInterleaves continuous media stream with control streamUses discrete session id (RTSP) or UDP (rtspu)Server and client can issue requestsServer maintains state (Play, Pause, Record, Stop)Request-URI always contains absolute URIData delivery takes place out-of-bandRTSP is not tied to RTPSupport for proxies, tunnels and caches as in HTTP/1.1


VideoRTSP Methods

DESCRIBE—retrieves the description

SETUP—start an RTSP session

PLAY—starts stream transmission

PAUSE—temporarily halts a stream

RECORD—saves stream transmission

TEARDOWN—session ceases to exist

OPTIONS—ANNOUNCE, GET_PARAMETER, REDIRECT, SET_PARAMETER

Network Impact for Digital Media

Delay:VOD: No impact due to the service nature itself Live: No impact. Will not disrupt the conveyed message.Too high will lower user experience (start of a video or change between videos)

Jitter:If too high (seconds) lead to buffer overflows packet leakage artefacts/”blacks”If sub-second player will leverage its buffer. Most players buffer could be tuned

Packet loss:< 0.1% > 0.1% lead to artefacts and “blacks” (lost of key frames)Some codec’s are quite robust in packet loss recovery (i.e. WMT 9+).

1: Choose a Redirection MethodSimplified Hybrid Routing1. DNS admin delegates domain cdn.company.com

to Content Router (CR)2. Web publisher publishes video with

http://cdn.company.com/video.asf.asx3. Client clicks on link4. Client makes DNS query for cdn.company.com5. DNS sends NS record for CR6. PC sends DNS query to CR for cdn.company.com7. CR returns its own IP address for cdn.company.com8. PC requests http://cdn.company.com/video.asf.asx

request to CR9. CR sees client IP address (not DNS) and sends a 302

location redirect to http://ce1.ce.cdn.company.com/video.asf.asx

10. Client resolves ce1.ce.cdn.company.com from CR11. CR returns local ce1-ip based on coverage

zone routing12. Client makes request

http://ce1.ce.cdn.company.com/video.asf.asx to ce113. CE1 generates a dynamic video.asf.asx file with an

MMS/RTSP link in the form of mms://ce1-ip/video.asf14. CE1 servers the VoD or live stream as appropriate

Live Multicast to DMP Interaction1. Video Source feed into MP2TS/UDP

Encoder 2. Encoder joins and streams to multicast

group in multicast network3. DMM Publishes Multicast Application or

URL of a HTML page with multicast video configured in a zone fromwebserver to DMP

4. DMP requests HTML page with multicast configured from webserver

5. Webserver serves HTML page to DMP

6. DMP sends IGMP join request to multicast group

7. Multicast network joins DMP and streams multicast video to DMP

8. DMP displays multicast video within a zone using HTML page or full screen video without using HTML page.

Lessons LearnedNTP Sync Systems

Sync scheduling of DME for live events

Sync time between DMM and CVP for SFTP connections

Release/End dates of Cisco Video Portal content

Sync schedule of DMM-DSM Scheduler

Most important!!Digital Signage Scheduler uses time stamps on the content pieces

DMP will request the content based on commands from DMM. If ACNS cannot match the time stamp, the content will not play!!

Lessons LearnedScaling DMP Boot and Firmware Upgrade

No Network boot today. DMP boot only from local flash.

Upgrade Multicast

DMM instruct DMP on MCast Group

MCast Start, DMP Join

DMP assembles firmware image and starts upgrade

Unicast

Upgrade application in DMM

Firmware content is managed like other content but with different content type (DMP Firmware)

Publisher could be used to schedule upgrades

Could leverage ACNS pre-positioning


Lessons LearnedContent Is King

Anyone who has basic HTML and web design knowledge can create signage content. It is not a given, however, that content that looks good on a computer will also look good on a signage display. There are various tools that the user can adopt to create appropriate contentRecommended for content creation:

Adobe DreamweaverAdobe Flash 6.0 and 7.0Adobe Photoshop Adobe PremierAdobe Premier ProSony VegasVLC

Basic HTML, static images, PowerPointfor general audience

Advanced HTML, Flash animationfor Web designers/creative agencies

JS API to the DMPfor Web/SW developers

VideoAuthoringfor creative

agencies

Skill sets for specific audiences

Content Creation Pyramid


41


Lesson LearnedFlash and Video Content

DMP has 2 CPUsDMP 4400 Support H264 and perform better for flashFlash 6.0 or 7.0 supportedUse Flash HW acceleration only if “Flash Full Screen”Use 12fps frame rateAnimations of small objects, small movie clips with little movements work very well

Do not create more than one effect in the same time line segmentDo not use resizing at the same time or use large resizingDo not use shape tweening, or on very small shapesObject effects do not happen simultaneouslyAlfa works better on small objects

Not use imported video

Flash Video


Lesson LearnedAudio Only

Create a MPEG file with a 1x1 black pixel as the video

Audio file compressed with MPEG is lot larger than the normal MP3 compressed file

1. On-Demand is HTTP progressive download only with no session control (i.e. RTSP)

2. Live is MP2TS over UDP over MCAST

3. Either MPEG1/2 or H264.AVC encoding

4. Frontend ETV is part of the DMM platform

5. ACNS integration is though the Digital Signage module

6. ETV Frontent is one Digital Signage predefined application Could be scheduled

7. ETVM need internet access for EPG download from Chicago Tribune services
