Abstract
According to one embodiment of the invention, a method for improving video quality by leveraging time zone delays occurring during transmissions of programs. The method comprises an operation of determining a time zone delay between a broadcasting source of a program and a targeted destination for the program. Thereafter, the program is transmitted to the targeted destination where the resolution is equal to at least twice of a normal resolution and/or transmission data rate is equal to no more than one-half of a normal transmission data rate.
Claims7
A method comprising:
- determining a time zone delay for a program transmitted over the Internet between a broadcasting source in a first time zone and a targeted destination in a second time zone, the first time zone being different than and leading the second time zone so that a local time at the first time zone is ahead of a corresponding local time at the second time zone;
- and
- transmitting the program to the targeted destination at a higher resolution than a resolution of the program transmitted within the first time zone, wherein
- the resolution of the program being increased up to a factor computed by (1) a result of the duration of the program added to the time zone delay, divided by (2) the duration of the program, and
- the program being transmitted is not required to reach a destination viewer at the targeted destination until the local time at the second time zone corresponds to the local time at the first time zone when the program was transmitted.
