  • Executive Summary Video operators need to transport high-quality and time critical video streams at the lowest possible cost, which increasingly leads them to explore IP network based approaches including the public Internet. However, during transmission across an IP network a packet may be delayed with no guarantee of arrival at a specific time, or in the same order as transmitted. Since video is extremely time sensitive it follows that transmission of high-quality real-time video over IP networks is very challenging.

    The light weight UDP real-time data delivery protocol was designed for streaming video applications but assumes network nodes are not congested. However, a key problem is that IP network routers will simply drop UDP packets when congested, without notifying the sender. This is a critical issue with video delivery over IP networks, especially when UDP video has to compete with TCP/IP data traffic. It is well understood that streaming video using UDP is affected by TCP traffic and its demanding flow control mechanism whenever TCP and UDP share a node, and hence the UDP transmission may experience packet loss.

    TCP, a heavy weight protocol by comparison, is neither suitable for live video distribution, nor high bitrate live ingest to Content Delivery Networks (CDN). This is due to the protocol's flow and congestion control mechanism, which interprets packet loss as evidence of bandwidth limitations and in response reduces the packet transmission rate. This is exacerbated over longer distances, and when traversing multiple networks, both which tend to increase the packet loss rate, thus reducing the effective throughput.

    HTTP-based adaptive bitrate (ABR) protocols are designed to ensure the best possible video quality for any given bandwidth and screen resolution. The client device selects the video stream that is most optimal to local circumstances, but that is by itself not a guarantee of a broadcast Quality of Experience (QoE).

    Therefore, to maintain the quality of real-time video transmitted over IP networks, while also minimizing transport cost by utilizing the Internet, a different approach is required.

    Enter the award winning "DOZER" technology, integrated in DVEO's encoders/transcoders and receivers. DOZER literally "bulldozes" real-time video through IP networks, including the Internet, in a deterministic manner thanks to its ability to automatically correct for UDP packet loss, thus safeguarding the video quality.

    DOZER is a real-time IP Gateway technology featuring an end-to-end error correcting protocol that delivers time critical video reliably over UDP, whether unicast or multicast. It enables smooth MPEG-2 and H.264 SPTS and MPTS delivery of both SD and HD services through DVEO patent pending Automated Packet Recovery algorithms for alleviation of packet delay variation and outright packet loss, and re-ordering of out-of-sequence packets.

    The DOZER is a cost-efficient solution for a variety of UDP video applications by making them virtually immune to out-of-sequence packets and outright packet loss, and using a minimal sub-second latency buffer necessary for accurate, high quality video transport. The DOZER is commercially available in three versions enabling error-free UDP video transport for contribution or distribution over all types of IP networks including the public Internet:

    1. DOZERbox II IP/IP, a compact stand-alone product (pictured).

    2. DOZER Racks IP/IP, 1 RU.

    3. DOZER APR: LIC, a software license for integration in third-party products, and an available option in DVEO encoders/transcoders and receivers. This version allows customers to originate and terminate video delivery without requiring additional hardware devices, thus reducing both CAPEX and OPEX.

  • 2 The Challenge: Delivering Broadcast Quality, Real-time Video over IP Networks 2.1 Introduction to Internet Protocols

    Internet data traffic is generally transported using the ubiquitous Transport Control Protocol (TCP), a part of the Internet Protocol suite (TCP/IP), which has a built-in packet recovery mechanism to guarantee delivery. TCP provides reliable, ordered, and error-checked delivery of packets between applications running on hosts communicating over an IP network. Since non-video data traffic is not as time sensitive as real-time video, the potential delay imposed by the TCP/IP packet recovery mechanism is typically not critical.

    However, since the packet recovery time will vary from one congestion scenario to another, TCP-based protocols are neither suitable for live video distribution, nor high bitrate live ingest to CDNs. This is due to the protocol's flow and congestion control mechanism, which interprets packet loss as evidence of bandwidth limitations and in response reduces the packet transmission rate. This is exacerbated over longer distances, and when traversing multiple networks, both which may increase packet loss rates, thus reducing the effective throughput.

    By comparison, the light weight User Datagram Protocol (UDP) offers an efficient method to deliver real-time data to a large number of clients such as in streaming video applications. UDP is stateless and uses a simple connectionless transmission model with a minimum of protocol overhead. It also supports multicast, i.e. sending a single packet to multiple receivers. UDP emphasizes low latency over reliability and by design only offers a "best effort" service level (no packet recovery). Consequently some transmitted packets may be lost or delayed with no guarantee that they will arrive to its intended receiver or at a pre-determined time, or in the original sequence.

    Another protocol such as the Real Time Protocol (RTP), which runs on top of UDP, supports packet re-ordering and de-jittering, to a degree, but like UDP it does not offer packet loss recovery.

    While there are some potential solutions to these issues, such as Forward Error Correction (FEC) protocols, they either require substantial additional bandwidth permanently and/or will delay real-time video delivery in an undesirable manner.

    A potential alleviator of network bandwidth variations is Adaptive Bitrate Streaming (ABR), with protocols such as Apples HTTP Live Streaming (HLS), Microsofts Smooth Streaming, Adobes HTTP Dynamic Streaming (HDS) and the emerging MPEG-DASH standard (Dynamic Adaptive Streaming over HTTP). Common to all is that they will encode the video at various bitrates, ranging from HD quality to lower bitrates that may offer a basic or even decent experience but not a broadcast QoE. The client device selects the video stream that is most optimal to local circumstances, which ensures the best possible QoE for any given bandwidth and screen resolution. This is useful for multiscreen video services to devices of varying display capabilities and across various network types, but that is by itself not a guarantee of a broadcast QoE where it matters most.

    While CDNs are increasingly used to overcome real-time video quality issues, this is limited to the traffic within the CDN infrastructure. So, no matter how solid a CDN is internally, if the video quality is impacted already between the video origination point and CDN ingest, no CDN can restore it. Therefore, special care need to be taken when transmitting live video from its source to the CDN ingest facility.

    UDP by design only offers "best effort" service - packets may be lost or delayed, or arrive out of sequence.

    TCP-based protocols are neither suitable for live video distribution, nor high bitrate CDN ingest.

    No matter how solid the CDN, if the video quality is impacted before CDN ingest, no CDN can restore it.

  • 2.2 Broadcast Video Delivery Issues As framed in the previous section, broadcast quality, real-time video delivery over long haul and multi-hop Wide Area Network (WAN) connections has always been problematic. Real-time ("streaming") video is extremely time sensitive and IP networks subject it to several types of transport induced issues. Moreover, video transmission across multiple networks, and between cities and countries, may involve several network operators thus exacerbating challenges such as:

    Packet Delay Variation: Minor variations in packet arrival time, sometimes referred to as jitter, occurs due to network congestion, timing drift, or route changes. Variations in packet latency across a network can cause problems if the latency exceeds the jitter buffer size as defined in HW or SW.

    Packet Loss: UDP packets may not arrive at all, since UDP does not have a built-in packet recovery mechanism, and with no notification provided to the sender. The probability of packet loss increases linearly with distance since the number of hops traversed is generally larger. When and if this occurs, video quality is impacted and at some point it becomes unacceptable.

    Dedicated and over-provisioned network infrastructure has long been the norm for telcos and cable operators, as well as dedicated CDNs, to minimize jitter and packet loss rates. Such networks offer near perfect Quality of Service (QoS) but at a price and, nevertheless, are still subject to discontinuities and (albeit low) packet loss. This is particularly egregious when video traffic is routed over "bursty" fiber connections.

    Video over Local Area Networks (LAN) generally offers a near perfect QoE. Provided there is sufficient bandwidth and little TCP traffic, congestion can be really low although rarely eliminated. It turns out that switches and routers are not yet perfectly tuned for video and quite often introduce jitter, discontinuities and dropped packets. This is caused by bandwidth contention between TCP and UDP packets.

    2.3 Solving the Real-time Video Delivery Conundrum

    Using UDP to transmit video over the public Internet offers great potential savings but requires the addition of a low-latency packet recovery mechanism. Therefore, to maintain the quality for real-time video transmitted over IP networks, while also minimizing cost by utilizing the Internet, a different approach is required. As will be presented next, the award winning DVEO DOZER technology offers a science-based and proven solution that guarantees the quality and minimizes cost for real-time video over any type of IP network.

  • 3 DOZER II IP/IP Solution Architecture, Components and Key Features 3.1 The Solution: DOZER II IP/IP by DVEO

    As noted, a key issue is that IP network routers will simply drop UDP packets when congested, without notifying the sender. This is a critical issue with real-time video delivery over IP networks, especially when UDP video transmissions have to compete with TCP/IP data traffic.

    Enter the award winning "DOZER" technology, integrated in DVEO's encoders/transcoders and receivers. DOZER literally "bulldozes" real-time video through IP networks, including the Internet, in a deterministic manner thanks to its ability to automatically correct for UDP packet loss, thus safeguarding the video quality.

    DOZER is a real-time IP Gateway technology featuring an end-to-end error correcting protocol that delivers video services reliably over UDP, whether unicast or multicast. It enables smooth MPEG-2 and H.264 Single Program Transport Stream (SPTS) and Multiple Program Transport Stream (MPTS) delivery of both SD and HD services through DVEO patent pending Automated Packet Recovery algorithms for alleviation of packet delay variation and outright packet loss, and re-ordering of out-of-sequence packets, with fixed sub-second latency that is a cost of implementation.

    DOZER implements proprietary and sophisticated data and streaming management algorithms in order to optimize traffic that across IP networks. Based on IP-stack oriented software, DOZER sends a minimal set of unique signaling packets along with the original packets. A key feature is Automated Packet Recovery, which means that DOZER only requests a packet re-send when packet loss is detected. Contrary to the Forward Error Correction (FEC) approach, DOZER does not consume extra bandwidth on a permanent basis and does not impose a latency that would be unacceptable. Maintaining the light weight design of UDP, DOZER simply takes corrective measures as necessary.

    Importantly, DOZER does not examine the underlying traffic and it will not alter the internal structure of the Transport Stream. Regardless of whether the content is present in the clear or already processed by a conditional access/DRM system, DOZER applies strong AES encryption before transmission while decrypting it at the receiving end before passing the content along to the application.

    3.2 DOZER Applications The DOZER is a cost-efficient solution for a variety of UDP video applications by making them virtually immune to out-of-sequence packets and outright packet loss, and using a minimal sub-second latency buffer necessary for accurate, high quality video transport. For example, customers in the U.S. use DOZER technology to import video content from countries such as Bangladesh, Colombia, Greece and Iraq with no packet loss or video freezes, and lower latency than FEC-type protocols. An Asian IPTV operator uses the DOZERbox to reliably transfer video between cities, and a TV station in American Samoa between islands. Customers also create low cost CDNs over the Internet. In other words, DOZER technology improves video delivery over both the Internet as well as managed networks.

    3.3 Award Winning Technology The DVEO innovation won the prestigious Society of Broadcast Engineers (SBE) Technology Award for 2014 for the DOZER IP video traffic smoothing technology. Only one SBE Technology Award is granted each year, and it recognizes the SBE Individual or Sustaining Member who has provided the industry with the best new or innovative technical item to further the science of broadcast engineering. www.sbe.org

  • 3.4 DOZER Solution Architecture The video head-end consists of a number of components such as video encoders and transcoders, streaming servers, digital rights management systems (DRM), etc. DOZER is the final component that processes the content stream before transmission. On the receiving side the reverse sequence applies with DOZER as the first component to process the content before decoding and output. Moreover, it can be configured for point-to-point or point-to-multipoint functionality (see Figure 1), and each device can be configured as Sender, Receiver, or both. For more features, see the list on the next page.

    3.5 DOZER Versions The DOZER is available in three versions enabling error-free UDP video transport for contribution or distribution over all types of IP networks including the public Internet:

    1. DOZERbox II IP/IP, a compact (4.6 in. / 117 mm square) stand-alone product as pictured in Figure 1.

    2. DOZER Racks IP/IP, 1 RU form factor for rack mounting.

    3. DOZER APR: LIC, a software license for integration in third-party products, and an available option in DVEO encoders/transcoders and receivers. This version allows operators to originate and terminate video delivery without requiring additional hardware devices, thus reducing both CAPEX and OPEX. DOZER is an available option in a wide range of DVEO products, such as the MultiStreamer and Mamba DIG/IP encoders/streamers, Gearbox and Gearbox II transcoders, Atlas Media Server and Brutus transcoder/media server.

  • 4 DOZER Use Cases 4.1 Application Versatility

    Studies and real world usage indicate that each type of network, whether LAN, WAN or dedicated and conditioned network, can be perfected by a properly configured pair of DOZERS or DOZERIZED encoders, decoders and gateways. When video packets transits corporate networks, packet loss is likely low. When packets transit dedicated lines, packet loss is higher. When video packets transit public Internet then packet loss is obviously much higher.

    The DOZER is a cost-efficient solution for broadcasters, mobile operators and telcos for a variety of application and deployment scenarios by making transmissions virtually immune to variable latency, out-of-sequence packets and outright pack loss, and by not delaying time critical video like FEC technologies do.

    DOZER ideal for:

    Delivery of multiscreen services over networks that do not offer QoS guarantees such as the Internet Multi-network and multi-country transfers for content producers and service providers Streaming studio quality live news and sports programming over congested backbone networks Replacement of expensive point-to-point managed network connections and traditional satellite

    backhaul by creating low-cost CDNs using any type of network including the public Internet

    Enhance video delivery reliability and quality also over managed networks where UDP video transmissions have to compete with TCP/IP data traffic the latter is prioritized by network routers and will lead to dropping of UDP packets when the router buffers fill up. The DOZER technology will recover the lost packets with extremely low latency, thus preserving the real-time video delivery.

    4.2 Multi-Island Distribution American Samoa KVZK-TV was the very first television station in the South Pacific, celebrating its 50th anniversary in 2014. It was facing a major challenge in distributing its content over IP to the five islands of the territory. They tested and eventually chose IP video encoding equipment from DVEO, also outfitted with the DOZER technology. This solved their content distribution problem and saved money per Daniel Langkilde, Director of the Office of Public Information at KVZK-TV: "Our American Samoa TV network was having major inter-island communications issues with IPTV. The DVEO encoders with built in DOZER saved us large amounts of money by not having to use Satellite Links between islands."

    4.3 Point-to-Point One of the top three U.S. broadcasters uses DOZER to connect between East and West Coast facilities. They found noticeable packet loss on their dedicated lines and now rely on DOZER on top of their Telco conditioned lines. The video drop outs are now non-existent.

    4.4 Multi-Country Distribution Ellas TV is an ethnic channel content originator. It needed to bring content from Greece to the U.S. and found the DOZER to be extremely price effective when compared to using satellite, dedicated lines, or CDNs.

    4.5 Studio to Transmitter Link (STL) I installed the DOZER system as a backup STL to protect my leased lines. The ASI transport is accurate and very reliable. The DOZER system makes the Internet act like a leased line and saves considerable money in the process. I will be ordering another system for a different station very soon. Peter A. Douglas, Director of Engineering, NRJ/Titan Broadcast Group (USA).

  • 4.6 Conclusion As can be seen from the above use cases, DOZER technology benefits UDP video transmissions over any type of IP network, whether the public Internet or dedicated lines. It alleviates packet loss and various other forms of delivery problems such as packets arriving out of sequence.

    4.7 Next Steps and Resources While this document has provided an introduction to the DOZER technology, the proof is in testing it in the network environment that applies to each potential user.
