Abstract

Examples are disclosed for transmitting video content. In some examples, cyclic redundancy check (CRC) values may be added to video content for video frames to be presented or displayed in a given region of a display. Results of CRC functions for consecutive video frames that use the added CRC values may be compared to determine whether the video content for the consecutive video frames is static video content. Video content for at least one of the consecutive video frames may be withheld from being transmitted if the video content for the consecutive video frames is characterized as static video content. Multiple CRC values or different CRC values may be added to further determine whether video content for the consecutive video frames or for subsequent consecutive video frames is also characterized as static video content. Other examples are described and claimed.

First claim

What is claimed is:

1. An apparatus comprising:
circuitry;
a receive module to be executed by the circuitry to receive video content to be presented in a first region of a display;
a cyclic redundancy check (CRC) module to be executed by the circuitry to add a first and a second CRC value to the video content;
a function module to be executed by the circuitry to generate first and second results of a CRC function for respective consecutive first and second video frames for t…
