Techniques for transmission and preparation for display of real-time audio-visual content of a plurality of TV programs over electronic communications network channels and display of the audio-visual signals as a part of a TV Electronic
Programming Guide (EPG) are disclosed herein. In particular, the use of video coded using a layered codec, and stored in a layered format, allows a properly configured
system to present to an
end user a
live preview of multiple TV channels, along with EPG information (e.g., the channel, time, title and genre of video content, a
list of programs scheduled in the future, as well as the ability to, for example, set parental controls, order pay-per-view programs, to search for programs based on theme or category, and to set recordings for the future when combined with a
recording system), on his / her TV screen, without taking significantly more resources (e.g., in terms of bandwidth,
system complexity) than the traditional digital TV transmission.
