AVB software architecture on ARM Cortex SOCs
Summary: Traditional clocking synchronization in networked A/V systems is done via elaborate means. In the automotive sector, the clock synchronization of displays and multi-channel audio in an infotainment platform is implemented using MOST, which is an isochronous environment. In the Pro-A/V area, the displays are synchronized through a combination of separate master clock control link and fixed delay compensation depending on the length of the control link. Synchronization thus has been a tedious and time consuming exercise. Standard Ethernet does not provide QoS and it is an asynchronous environment, although topologies exist to provide it today.
The Ethernet AVB Protocol (IEEE1722+IEEE1588 or 802.1AS) in one such standard that formally brings a QoS and synchronization implementation to Ethernet. By providing global time synchronization mechanism combined with a protocol of prioritization of streams as they pass through switches, Ethernet AVB offers an Isochronous environment similar to that of the MOST bus. Ethernet AVB protocol allows widespread proliferation of Ethernet standard in Automotive, Pro-AV and Pro-Audio systems.
Examples of Ethernet AVB application are:
1) Automotive ADAS in surround camera architecture
2) Automotive Infotainment End points
3) Pro A/V video wall projection system and
4) Multichannel Sound system for Automotive, Studio Environments.
Overview of VoIP (Voice over IP) and FoIP (Fax over IP) technologies like Session Initiation Protocol and H.323.
Even though voice over IP (VoIP) was hailed as a technological innovation, the idea to transport real-time traffic over TCP/IP networks was not new back in the 1990s when VoIP started being deployed in networks. Chapter 2.5 of the venerable RFC793 (TCP) shows both data oriented application traffic as well as voice being transported over IP based networks.
Nevertheless, VoIP puts high demands on signal and protocol processing capabilities so it became possible at reasonable costs only in the 1990s.
VoIP can be roughly split into two main functions. Signaling protocols like SIP (Session Initiation Protocol), H.323 and MGCP/H.248 are used to establish a conference session and the data path for transporting real-time voice data packets. SIP has largely supplanted H.323 in recent years to its simpler structure and packet sequences. MGCP and H.248 are mostly used in carrier backbone networks.
Protocols like RTP (Real Time Protocol) transport voice packets and provide the necessary information for receivers to equalize packet flow variations to provide a smooth playback of the original voice signal.
Voice codecs are one of the core functions of the data path. Voice compression reduces the bandwidth required to transport voice over an IP based network. Compression may be less of a concern in local area networks with gigabit speeds, on slower links like 3G (UMTS, LTE) it still makes a lot of sense.
The algorithms used in different codecs make use of various characteristics of the characteristics of human speech recognition. Redundant information is removed from the signals thus slightly reducing the quality, but greatly reducing the required bandwidth.
In VoIP networks, the echo problem is typically compounded by the increased delay incurred by packetization of voice signals. To counteract the echo problem, VoIP gear (hard phones, soft phones, gateways) include echo cancelers to remove echo signals from the transmit signal.
To transport facsimile over an IP based network, even more technology is needed. Facsimile protocols are very susceptible to delay and delay variation and thus need more compensation algorithms. Protocols like T.38 terminate facsimile protocols like T.30 (analog facsimile) and transport the fax images as digitized pictures over IP based networks.
In this presentation I present some basics of multimedia streaming such as: Multimedia Communications- Multimedia Streaming Apps- Characteristics of Multimedia - QOS - Streaming Stored Audio And Video

44CON 2014 - GreedyBTS: Hacking Adventures in GSM, Hacker Fantastic
There are over 2.9 BILLION subscribers on GSM networks today. How many of these subscribers are susceptible to trivial attacks that can leave phone calls, text messages and web surfing habits accessible to an attacker? This talk intends to discuss the reasons why GSM networks are still vulnerable today and demonstrate attack tools that might make you re-think how you handle sensitive data via your phone. The presenter will discuss his own experience of analysing GSM environments and provide a demonstration of GreedyBTS which can be used to compromise a targets phone calls, messaging and web surfing habits. Mobile Phones will be harmed during this presentation.
Ed Adams, CEO of Security Innovation, along with Brian Witten from Symantec address the trade-off between safety, security and convenience as well as the steps that need be taken by manufacturers before we can trust our the new IoT ecosystem to deliver the promised benefits of connected services.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

2. What is CAS?
A Conditional Access System is the collection of security
components in the end-to-end pipeline of broadcast media,
from source headend equipments to client devices.
PayTV systems generate revenue by enabling media content
rights exclusively to viewers who pay for it.
“Paid channels” or channels with premium content, which are not
available free-to-air.
Video-on-demand and movie-on-demand services.
In simple terms, in general, all devices in the network can
theoretically get access to all the available (free-to-air and
encrypted) media contents/streams. But only those devices
with some specific keys can view the encrypted/protected
contents. The secure management of these keys in the open
network, is the prime responsibility of a CAS vendor.
3. Types of CAS in PayTV systems
Smartcard based solution
Smartcard contains proprietary security logic for decryption.
Proven and tested, and most widely accepted solution.
Recovery time after hacking is high, since cards need to be
replaced.
CAM-based solution
Similar to smartcard based, but the device is just provided with
a slot for CAM module, and any smartcard (meeting CAM
requirements) should be able to work.
More open standard, but poor adoption by market leaders.
Cardless or full-software solution
SoC level security features are used by software modules.
Relatively newer technology, cheaper and growing in
popularity.
Recovery time after hacking is very low, hence discouraging
hackers.
4. CAS for Broadcast Networks
The next few slides explain the end-to-end
management of secure content.
This is a very generalized and simplistic explanation
(intended for engineers with DVB background), and
not specific to any particular CAS vendor.
The basic concept would be similar for all Broadcast
CAS systems, with slight variations in the number of
levels for key encryption, key ladder logic,
encryption/scrambling algorithms used, etc.
