e-interview with Mr. Aytaç Biber on 5G Broadcast

I did not have chance to personally meet with Mr. Aytaç Biber who is working at Qualcomm as Director of Product Management, but with the help of IBC 2022, we managed to know each other. I prepared the questions with my collegue Mr. Halil US.   I appriciate for the answers of Mr. Biber, hope you enyoj the interview.   Q1. Can you please tell us your 5G solution. 5G broadcast is a new media delivery framework defined by 3GPP standardization body. It defines two modes of communication: 1- Standalone broadcast where a dedicated broadcasting network such as a single frequency network (SFN) is used for downlink broadcast . This could be live distribution of mass media content such as digital TV, live sports and digital advertisement content for billboards. This would be more tailored towards traditional broadcasters. 2- Mixed mode broadcast where low power , low tower networks could be used in hybrid mode with media client switching between unicast and broadcast for more efficient delivery o

post IBC 2022: 5G Broadcast

There is a saying in Turkish. If I try to translate it, I guess it is something like this: "Everyone describes an elephand depending on where he/she grabs." I believe there is also one in English which has similiar meaning, I would be glad if you can share that in the comments. I have been working in broadcast since 1998 and worked on digital terrestrial broadcast since 2003. So, the my main interest was DTT again. But this time not DAB+ / DRM+ nor DVB-T2. My main point of interest was 5G Broadcast.  There was actually one single company which was demonstrating 5G broadcast, namely Rohde & Schwarz. They were doing the demonstration with the receivers which have chipsets from Qualcomm. So this demonstration was in a way the demo of R&S and Qualcomm. But I had the chance to talk to other big transmitter companies. The advance of IBC is that you can find top level executives to talk with on the subjects that you are interested in. So these guys told me that even though t

What will 5G bring to broadcasting?

To be honest, I do not know the answer of the question: What will 5G bring to broadcasting? But, with the help of some documents, I will try to comment on this. It would be great if you also can share your opinions. "Broadcast", "unicast" and "multicast" are different ways of connection. Visualization is always better way of explaining: As you can see in the figure above, Unicast is point to single   point connection; Broadcast is point to all connection; Multicast is point to many points connection.  In broadcast connections, quality does not depend on the number of receiving units. So for serving same data to crowded receipents some kind of broadcast network should be used.  Mobile networks were providing unicast connections, i.e. from the base station to the receiver. Multimedia Broadcast Multicast Service ( MBMS ) is a broadcast/multicast service in mobile networks, which is available since 2009 . But it has not been common
