Interactivity and control may become important features for video service

Mobile is still quite free from advertisements


I think that advertisers are not using mobile media much. 

I think people will be ready to pay more for better video experience

listening offline from Bangalore, India!

Thank you very much both Jason and Alan. I learned a lot of new stuff today! Such an eye opening solution to an impending problem

Thanks Guys..Enjoy your day..


Great presentation and discussion.  Thank you

Thanks everyone for tuning in today, we'll see you back here on Friday for Video: The Case for Virtualization! 

Good afternoon. I am in Crownsville, Maryland. Very hot and humid!

Thanks for allowing me to participate!

Thanks, Jason and Kelly. Let's do it agan soon.

Thanks again @Alan and @Jason !

Again, if you have any other questions I might be able to answer, hit me up via email: [email protected]

Hi, everyoe. This is Alan. Gotta log off now. But feel fee to shoot me any questions at [email protected] 

@Alan and @Jason Thanks so much for the excellent presentation and for answering our questions!! It was great having you both present today!

Also, someone mentioned what is stopping LTE-B. I posted that Verizon used it during the Suoer Bowl a few years back, but I have not heard of any network wide deployments. Do you know of any deployemtns? What are your thoughts?


@msilbey regarding your LTE-B comment, I believe this will become a transparent technology. I think that was the original problem: they operators tried to "productize" it. In the future, you won't see much about it. It's just the way that operator networks will deliver video traffic.

Thank you for addressing my questions. I appreciate your taking the time to discuss them. Wonderful presentation.

@Kelsey. it shouldn't, because the demand for video is so great that it will more than offset the greater efficiencies achieved.

@Business I'm reposting questions but please go ahead and repost yours, thanks!

Business82603 regarding your "gap" question, yes, that is the gap. Hence the need for greater macro cell network density to provide the kind of connectivity that people need while they are "in transit."

I posted some questions during the session. Will you go back or should I repost?


@kelsey. Definitely not! Mobile devices are becoming the go-to device for video and people want broadcast quality regardless of what device they are on. I think mobile devices will actually drive higher bitrate delivery.



Is broadcast is easier than multicast in implement?

@BUSINESS826903 Sure. Thanx for supplying it, assuming you're from Ericsson.


@Jason/Alan: Q: 

Won't mobile devices reduce or slow the growth of video data demand via downscaling (that is, by requiring less data due to the smaller size and lower resolution requirements of the mobile display compared to other displays, such as high resolution TVs and laptops)?

@keylsey no, no problems there that I have ever heard of.


thanks fot this class


This is Jason. Thanks everyone! Hope you enjoyed the presentation. Lots of great questions asked throughout. Wish I could get to them all...

If you have a specific question, don't hesitate to reach out to me at [email protected] and I'll try and get an answer to you.


very informative lecture. thank you jason and alan!!

@Jason and Alan - Listener Q: are there any copyright complications connected with storing video programs in multiple CDNs?

@vquinata good question. quite possibly

Great Session.  Thank you very much.

And Alan, thanks for using the Ericsson material

Great call, thanks presenters!

Do you anticipate video consumption to become the major use of mobile devices


Online video is the end game, for sure!  Mobility is driving it.

Absolutely. The projected improvements for wireless will help excelerate usage.


Enjoyed the presentation! Thanks!

Very informative presentation!  Thank you!

Thanks for this presentation, Alan, Jason and Kelsey.

Per @elmoor, agree: "no spiking.  demand will continue to grow no matter the delivery technology.  Data will always grow to fill the bandwidth available."

Software guys (programmers) say it is a harware issue, while the hardware guys (engineers) say it is a software issue.

The often stated fact is that 80% of mobile data is consumed indoor. But with indoor, there are options to connect to cellular or Wi-Fi to absorb traffic. But is that the gap for TV usage? Isn't the gap in locations where people are transiting? Int he car? Public transport? Outside of home or office?

Yes. 5G will be a big boost!

Hope the micro-cells don't look like the light pole units in LA.  Sky clutter!

A few years after.  It will take people time to discover that they can do and get more via mobile.


Verizon did experiment with LTE-B, but executives there also did a lot of conflating of LTB-B with other online video delivery systems - mixing LTE-B with talk about the service that eventually became Go90, for example. Have seen nothing big on LTE-B recently. 

In North America the spike started already bit in other side of world may be spike few year later.

Mobile video demand is related to user device quantity and penetration.  5G will raise network capacity a LOT.  Customer demand 'spike' will be when a peak is reached.  My vote would be very soon after 5G.


I think demand will continue to trend upwards and then spike with 5G.


After, because if the network does not provide the service it will put a damper on demand.  Consumers will not 'put up' with poor service.

no spiking.  demand will continue to grow no matter the delivery technology.  Data will always grow to fill the bandwidth available.  

Reply to second poll: should spike right after 5G, like a fire hose being opened

I think it is growing and will continue to grow regardless of the underlying network technology

It will spike in 2020, and grow very quickly to match adaption rates.


Yes - when 5G is available

Depends (what is the expected demographic and what is the availability of content quality and devices?)

Listeners, do you think demand for mobile video will spike when 5G emerges, which is projected for 2020, OR will demand spike a few years after? 

few years after because it takes time for new devices to become dominant

Yes. with 5G service availability.

Verizon did implement LTE-B  for the Super Bowl a few years back, but I haven't seen any information on a general network rollout.

LTE Broadcast could also be used to transmit the cached video (dlownload) to subscribers as well instead of streaming. It is very similar to the use case for sending out software updates to subscribers over LTE-B.

In multicast with a handheld device, can you pause live tv and and start back up or does the device require some memory to allow that?

what is holding back the implementation of LTE Broadcast?


@Duh! - You are right.  broadcasts that people want to watch in real-time (mainly news and sporting events) will benefit from multicast.  It is not really useful for the majority of OTT.

Only helps on broadcast.  Won't help on time-shifted viewing or 'unique to the Tower' video.

Multicast is clearly beneficial for popular channels of linear TV.  How does it help in a mostly time-shifted world?


With the arrival of eMBMS what is the impact on the LTE unicast capacity?

broadcast is easier than multicast in implememt?

Are there any commercial deployments of LTE-Broadcast in the US? Any specific deployment plans announced?

why not multicast instead of broadcast?


@Vkhanna01 (Of course trasparent caching only works for prerecorded static content.  Live streaming (sports e.g.) is entirely different.): That's a really good point. Would these CDN techniques be applicable with live streaming? How would live streaming be handled?

There is a glossary here: http://www.virtuapedia.com/proddir/dir_list.asp?dir_id=11

Of course trasparent caching only works for prerecorded static content.  Live streaming (sports e.g.) is entirely different.

QOE: Quality of Experince. Got it.

More CDNs (CPUs) means more vulnerability to hackers.

What is the Optimal Qoe in slid 25?


QUESTION: I apologize if this was already asked, but are there any copyright complications connected with storing video programs in multiple CDNs?

Can CDNs be virtualized? If so, has it been deployed in live networks?

Has Google got into the video business like Amazon?


Is the mobile video traffic coming more from OTTs like Netflix, Amazon, Hulu, etc. (longer form > 20 min)? Or is it more from You tube or Facebook that tends to be more short form <5 mim)?

How about inventing a better compression method? Cram more bits into the same pipleline, or remove bits (similar to MP3.MP4). The other option is to lay down more fibre. The speed of light is constant, so cannot grease light.

Looking forward to the Q&A sesion

Geographic area it is another fact for the networking/architecture , speed, CDn, access, and etc...


It depends how much money a company spend on the network archotecture.


Listeners...coming up on Q&A in a bit, start thinking about what questions you would like to ask Jason and Alan.

The buffering issue is not inherent to mobile devices. If your neighbors are using cable Internet and downloading large files, while you are trying to stream a live show, you will experience buffering delays.

@gnean ha! too funny...wifi rage

Funny , chatted about the picture in presentaion.


Is this called Wi-Fi rage, similar to road-rage?

@LAronowitz ("The State of Channel Develoment" is key to this concept but if it is deficient, then so is the outreach.): Good point, when measuing the absolute reach, but early adoption could be good for positioning on a new and growing channel.

Buffer rage is real...especially when streaming live events. LOL!

i was not able to hear , but after some time troubleshooting , i can now 


I wonder if the satisfaction gap on content availability and value is due to more 'skinny' or ' a la carte' offerings as opposed to 'thick' or 'fat' bundles.

I know that of the "140" channels I am offered by my local MSO, I am really only interested in 6-12 of them.  The OTT offerings tend to be narrower, but I feel that I am paying for what I want.  With traditional services, I may pay the same, but I feel as if I am paying not only for what I want, but also for what I DO NOT want.

In the first case (OTT), I feel I am treated fairly.  In the second (traditional), I feel as if I am getting abused (not liking 90% of what I am 'given').....


Not sure. May be not reaching the same level.

@John  "The State of Channel Develoment" is key to this concept but if it is deficient, then so is the outreach.

What happened in Q1/2014, why did video consumption decrease on slide 14


Congestion is issue and creats latency.

Reply to First Audience Poll Question: Adequate is a term that is relative, but because advertisers are moving quickly to take advantage, I will say yes they are adequately reaching consumers given the limitations of the channel and the state of channel development.

No, I don't think they are


No.  Presently, a consumer must seek out optons, compare offerings and make choices that are more guessing rather than based on facts.


No. Advertisers still behind.

No, but that is a good thing. I think the other thing about non-linear TV is that it less engrained with commerical breaks. Skipping ads first drove the Tivo experience and now with Netflix I don't have to watch any commercials


Measurement is still an issue for multiscreen advertising, so there's still work to be done. NBC isn't even counting online viewership for ad sales around the Olympics.

Thanks Jason, for tackling the infrastructure issue.

As a viewer, I believe they are.  Seem a bit intrusive AND repetitive at this point to insure viewers get the ads.


No, they need to find a new channel


Yes (advertising know where the eyeballs are.)

It's time for our first listener poll. Listeners, do you think advertisers are keeping pace with the rising subscriptions to over-the-top services? Are they adequately reaching consumers in this market? 

Advertisers are running to catch up..


amazing TV set still the main trench.

Wireless infrastructure moving to 5G, cable to DOCSIS 3.1  both provide Gbps potential.  Likely 2020+ before majority of major networks have this capability.


@tbate just type your response on teh chat board!

How does the poll voting work?

I have yet to hear anyone mentioning an upgrade to the network infratructure.

@jlockwood there is no video just audio :) remeber to download the slides!

Will this video streaming clog up the already slow network?

Overcast but nice today in So Cal

I have audio now in IE, but no video presentation


try using FireFox or IE! thsoe browers are producing the best qulity audio :)

Question for the presenters: Is there a viable business model for streaming video services where the content sselection is made dynamically (rather than subscribing to fixed "channels")?

After watching movies in Blu-ray + 4K 7.5 surround sound, there is no going back.

@jlockwood - I had to switch from Chrome to IE for this presentation.

it is not working in chrome for me. 


Hmmm...I have two audio streams going at once....one seems to be delayed by about 30 seconds....so hard to follow


@jlockwood it works in Chrome, but if you're having trouble try Firefox or IE

I love my mobile devices, too.

funny I had to get off my mobile device and onto a PC in order to attend this


Is this compatible with Chrome - I am not seeing anything.


No audio. Have tried 2 different browsers.


What is the projected quality of this streaming video? The current streaming services seem to be purely for 8" (or smaller) screens.

Audio just started again.

I don't have audio. I refreshed and still nothing. I'll try another browser.

@gnean yes we're excited to have 2 speakers today!!

@chigilpin I'm jealous, wish it was cooler in North Carolina!

Two presenters today? Whoaa!!!

Hi from San Diego, CA.  Of course the weather is beautiful.  Sunny and 75.

@PLenkam try freshreshing you browser! 

Seattle overcast, expecting sun 

in the afternoon


Arizona -- it's an oven here!

Northfield, MN Overcast with light rain


Atlanta, GA - Sunny and Hot

São Paulo, Brasil

Sunny and warm (this is my kind of Winter)

Does everyone have audio?

Takoma Park, MD - hot, humid

Listening in from British Columbia, Canada, where it is overcast and cool (59ºF/13ºC)

Virginia - Hot and muggy


QUESTION: Won't mobile devices reduce or slow the growth of video data demand via downscaling (that is, by requiring less data due to the smaller size and lower resolution requirements of the mobile display compared to other displays, such as high resolution TVs and laptops)?

@alanbreznick - Indeed. Looking forward to the presentation.

@dperson Ah. Gotcha. Well, we'll give you more ammunition here.


@Kkelsey. Sounds like it's time for swims instead.


@alanbreznick - Thanks. She actually has one. Just trying to convince her to use it primarily and cut her cable provider. :-)

Hi @dfperson. Maybe just buy her the Roku box as a belated Mother's Day present? 

@Alan it's humid and hot in North Carolina...no more outdoor runs for me!

For those just joining us, we'll get started in about 15 minutes. In the meantime, go ahead and download the slides from the link above the chat window!

Hi, Kelsey. Hot and dry up here.


Good day all...great to be here!

Great slides. I'm trying to convince my mom to cut her cable TV. She already has a Roku box. Hulu is so much cheaper than her local cable provider.

Hello from Ontario. Give my regardrs to Broadway. 

Hi @alan looking forward to it, too! How's the weather in NYC @LAronowitz?

Can't wait to hear Jason speak about this topic !!!

Hi, everyone out there. Looking forward to starting the session soon. Jason is going to do an amazing job.


Hi @hnaidu and @Sr.Direc, good to see you on the chat!

Looking forward to a great discussion.

Hi @wizard and @sa31 - glad you will be joining us today!

Dowloaded his presentation. it has good data.

Looking forward to the lecture

Looking forward to Jason's lecture today! The link to his presentation is above the chat window in the "Special Educational Materials" section. 

Greetings & salutations all!

Looking forward to the second lecture of the month!

Looking forward for better ways to perform video formatting, for instructional and documentry types.

QUESTION: I'm guessing video performance enhancements for mobile devices will require price adjustments. How elastic is this market to price increases?

Greetings and salutations all!

looking forward to the webinar!

Looking forward to sharing my knowledge with the class
