Component
Description of the solution
component concerned.
- PSIP
-
This is a system that provides channel/EPG information based on the ATSC1.0 PSIP standard in order to provide terrestrial HD broadcasting service.
Channel registration
- Channel information for basic channel tuning
- Encoding information for audio, video, and data stream of each service
- Channel branding (channel name and channel number) for broadcasting services
EPG data management
- Delivery of programming information (EGP) for each service channel
Support for value-added
service data
- Support for assistive broadcasting for the disabled (subtitles/screen commentary broadcasting/sign language broadcasting)
- 3D broadcasting service support
Regional broadcasting retransmission
- Headquarters→Regional broadcasting service channel/EPG information retransmission processing
- PSIP/SI
-
This is a meta-data EPG system based on the OpenCable standard designed to provide digital cable channels and EPG information. It collects, processes, and encodes the channel and programming information and value-added service information for digital broadcasting services, such as real-time, VOD, PPV, and VOD, and sends it to STB through the broadcasting network/DSG band.
Multichannel information
configuration and transmission
- The receiver provides channel information (frequency and modulation method) for basic channel tuning.
- Providing information for audio, video, and data stream of each service
- Providing channel branding (channel name and channel number) for PP
EPG data receipt and transmission
- Delivery of programming information (EGP) for each service channel
Value-added data transmission
- Providing the access control information of paid channels
- Support for VOD, 3D, and broadcasting for the disabled (caption, screen commentary, and sign language broadcasting) services
- Providing value-added information private descriptor for major cable operators in Korea
Cable platform optimization system
- Support for DVB standard-based terrestrial, cable, and satellite broadcasting services
- Support for domestic IPTV EPG metadata and value-added service information
- DVB-SI
-
The DVB-SI standard-based system transmits channels, EPG, additional data and metadata. It collects, processes, encodes, and transmits the channel and programming information and value-added service information for DTV, iTV, PPV, and VOD broadcasting services of DVB, T/C/S, and IPRV platforms.
