IPTV is unwilling to move forward independently to boost key technology development

IPTV is not an independent move forward. Its increasing maturity has boosted the development of several key technologies.

IPTV's business capability is embodied in quickly establishing a bidirectional transmission channel from the content source provider to the content receiver from the vast ocean of content, and providing reliable service guarantee and corresponding management mechanisms. From this perspective, IPTV's business capabilities are basically similar to those of traditional telephone exchange networks-exchange. To accomplish such a task and purpose, several key technologies determine the IPTV service capability.

Search technology required by content sources and content consumers

Unlike the telephone network, the initiator of a telephone call knows the recipient's phone number, while the content provider of IPTV does not confirm the specific content consumer, content consumers do not know where the content source is most satisfying. Audio and video search technology will become a strong demand in the IPTV technology field in the future, and will directly improve user experience and bring user loyalty.

CRM Customer Relationship Management) Technology

The CRM system will be a powerful tool for IPTV Business Marketing, including tracking user habits, analyzing user data, matching content with users, and supporting content marketing strategies. The huge IPTV user data will become the foundation for telecom operators to take advantage of the commercial market and become an indispensable data source for all commercial activities.

Media Exchange and Distribution Technology

Media Exchange and distribution technology is the basis for the transmission capability of the IPTV service platform. Compared with traditional VOD Systems, the IPTV service platform has higher requirements on the Content Delivery stack network. Similar to the traditional exchange network, how to quickly and effectively transmit massive media files and quickly forward and return the real-time data required by users in these media files when they watch the media to find the clips they are interested in) quick exchange to a specified location and client is critical to the performance of the IPTV Business Platform. Similar to the Exchange Network, business data transmission will never be completely encapsulated and transmitted at a time. If massive media files are transmitted and exchanged based on the size of the original media files, both efficiency and storage costs will increase significantly. The efficient and low-cost media exchange and distribution technology will determine the level of support and user experience of the IPTV Business platform for interactive and real-time services such as video communication and monitoring.

DRM (digital copyright management) Technology

DRM is an indispensable guarantee for IPTV services with media content as the core. The content carried by IPTV services is not only the assets of content providers, but also the subject of its legal rights and interests. Without DRM protection for media content assets, content operators, content providers, and service operators will not only lose their own interests, but also suffer from legal rights and interests. In China, secure broadcasting control is a basic requirement of the IPTV platform.

Error Control Technology

Error Control Technology will gradually reflect a huge amount of energy in IPTV services. How to provide reliable and quality real-time services on IP networks is one of the essential key technologies. From the NAL layer network abstraction layer in H.264 and AVS systems, we can see that solving errors in network transmission is the key to improving video quality. The AVS standard is currently studying the error control systems involved in overlapping networks such as media distribution and exchange to ensure that the error tolerance and Error Correction capabilities of video transmission can be improved in multiple aspects.

The combination of these key technologies will greatly improve the service capabilities of the entire IPTV Business Platform and play a direct role in the future IPTV service quality and management capabilities.
