Panther Express this week introduced a new guide designed to help in with process of choosing the most efficient way of delivering online video. Many companies and technical staff struggle with choosing between the advantages and features associated with the two main flavors of video delivery: progressive download and streaming.
Panther Express claims that it has helped many companies decide the best way to proceed. Many videos streaming features are now available through Panther via progressive download. For most situations, the company said progressive download is the better bet because most video and audio is delivered via Progressive Download HTTP
Panther Express’ Content Delivery Network (CDN) is an affordable way for users to access video content.
“Most end users cannot tell the difference between the video delivered by progressive download and that delivered via a streaming video server,” said Steve Liddell, CEO of Panther Express. “It all streams. It is not until you look very carefully at video player functions like how the navigation actually works (rewind and fast forward), that there is a difference.”
Liddell continued: “Most Internet Video is delivered by progressive download. For example, YouTube (News - Alert) video is delivered by progressive download. According to comScore Video Matrix, YouTube originates over 34 percent of all video delivered by US content providers. Our analysis of the top video sites has revealed that over 65 percent of video traffic, and over 55 percent of sites are using progressive download.”
The company claims that its network incorporates more than a decade of experience in HTTP delivery and is based on the latest Internet technologies and architectures as opposed to streaming protocols such as RTSP, RTP
, or RTCP that required proprietary players and expensive servers which were the only means available for streaming video years ago. These solutions were costly and did not scale well but offered more functionality at the time.
But technology is not available for video delivery via the standard HTTP protocol and this is less expensive and more scalable.
Panther says that by using metadata attached to encoded FLV files, Progressive Download can now allow users full seek and navigation at any time without requiring full file download. By using bandwidth throttling, it is now possible to deliver only the amount of video that will be viewed, preventing wasted bandwidth. And for maximizing security no-cache headers can be used to prevent browsers from storing content in cache and further DRM protection is easily available from partners.
