ISMA Announces 1.0 to Accelerate Standards for Streaming over InternetISMA 1.0 enables open-standards-based audio and video content streaming over narrow band, wireless and broadband quality networks (October 02, 2001)
ISMA 1.0 is the first implementation specification developed by the ISMA, a group of industry leaders in content management, distribution infrastructure and media streaming working together to promote open standards for developing end-to-end media streaming solutions. ISMA 1.0 provides a step-by-step implementation agreement that enables compliant components to be interoperable between different ISMA-supported vendors in the rich media marketplace.
For this specification, the ISMA has defined two hierarchical profiles. The first, Profile 0, is aimed to stream audio/video content on wireless and narrow band networks to low complexity devices, such as cell phones or PDA's, that have limited viewing and audio capabilities. The second, Profile 1, is aimed to stream content over broadband quality networks to provide the end user with a richer viewing experience. Profile 1 is targeted to more powerful devices such as set-top boxes and personal computers.
"As a first in the streaming media industry, ISMA 1.0 will allow content creators, owners, distributors and aggregators to be able to choose products and solutions from different vendors, and thus tailor their systems purchases to their exact needs," said Hans-Peter Baumeister, board member of the ISMA. "In addition, and also as a first in this industry, we can expect to see a truly competitive marketplace for streaming components and solutions, assuring continued improvements and innovation in this space."
ISMA 1.0 leverages the current industry momentum of MPEG-4 by adopting it as the compression standard. The specification defines the exact features of the MPEG-4 standard that have to be implemented on the server, client and intermediate components to ensure interoperability between the entire streaming workflow. Similarly, it also defines the exact features and the selected formats of the RTP, RTSP, and SDP standards that have to be implemented.
One of the major focus areas for the ISMA is the definition of a comprehensive compliance and interoperability program. With the enthusiasm of the companies represented by the ISMA membership, it is our expectation that this program will be defined by the end of 2001 with ISMA compliant solutions being announced in the first quarter of 2002.
The broad industry participation in ISMA will allow the content industry to rapidly embrace the concept of "one standard - one encode", regardless of the receiving platform, and provide the assurance for the consumers that their investment in rich media streaming devices will not be obsolete. Thus, the open-standards approach of ISMA offers the potential for major cost savings for the streaming media industry, and broad acceptance by the consumer.
