Hi.

Do any of you know or can you help me find out more information on this chipset?:  
  • BCM7251S Dual Core Mainchipest
New receiver supposed to be coming out around August and TEK2000 is advertising it as doing 4:2:2 MPEG4, while on the manufacturers website, I cannot find anywhere in the specs that it can handle 4:2:2.  Maybe I am just not seeing it, but I have not been able to find any consumer box manufacturer that is making or planning on making a box that will use a chipset that will support 4:2:2.  Hope I am wrong.

Thanks,

Rick

TitleBroadcom Debuts Multi-standard Ultra HD Chip Family
DescriptionBroadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today announced two new Ultra High Definition (Ultra HD) system-on-a-chip (SoC) devices that support Google's VP9 open video compression standard. Supporting client and media gateway set-top box (STB) applications, the BCM7251S and BCM7252S extend Broadcom's Ultra HD portfolio by adding VP9 decode support while introducing support for up to 60 frames per second on the new codec. Visit Broadcom's 2015 Consumer Electronics Show (CES) site to learn more at http://www.connectingeverything.com.

Broadcom's integration of the Google VP9 standard will allow users to stream 4K YouTube content to their set-top boxes and display to a TV. The codec provides up to 50 percent bitrate reduction for comparable quality compared to the previous VP8 standard and enables a significant new source of Ultra HD content in this rapidly growing market.

"As consumer interest in Ultra HD continues to grow, VP9 compression for streaming Ultra HD content on the web opens a new avenue for viewers to experience and engage in 4K," said Rich Nelson, Broadcom Senior Vice President of Marketing, Broadband & Connectivity Group. "Broadcom continues to build a flexible portfolio of devices with VP9 and HEVC compression standards to proliferate Ultra HD worldwide by enabling additional avenues for high-quality content consumption, such as YouTube."

Combined with the BCM4366, Broadcom's latest 5G WiFi device, the BCM7252S wirelessly delivers a fluid and life-like Ultra HD viewing experience throughout the home. The BCM4366 device provides 4x4 5G WiFi connectivity via a high-speed PCIe interface and incorporates multiple 802.11ac Wave 2 features to deliver up to a 4X speed boost compared to a traditional access point. It also significantly increases the reliability and robustness of the wireless content delivery.

Chatting with Octagon now and they say they are using the same chipset and we are making a recording of CBS now and will send to them and they are willing to see if it is possible that the Octagon SF4008 might be able to handle 4:2:2 feeds.

This is a good thing!

There is talk of this receiver ( Octagon sf4008 4k ) with that chipset at a forum over the pond being able to do 4:2:2 with the correct drivers.

Good news Rick.Hopefully there engineers can make it happen.

I found this document, which says something about certain broadcom devices being restricted if
destined for the German Market?? Not sure what that means but I know from experience that certain things may be restricted for export to certain parts of the world. Just thought that was odd..
Octagon is from Germany right?

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
