What's the relationship between U-Vision and Campus TV?
U-Vision is separate from Campus TV. While Campus TV may submit content to U-Vision, they are two distinct entities with different goals.
Does U-Vision accept submissions from students?
Yes, U-Vision allows students' submissions if the content relates to a university cause. For example, if you wish to promote an event related to your student society, please upload through that society's HKU portal account so that HKUSU can grant you approval for broadcast. If you wish to showcase your work for the subject you are studying in, seek your course tutor/lecturer to upload on behalf of the faculty/department. You may also try uploading using your own HKU portal account and wait for a longer process for us to help seek the your faculty/dept's approval for you. If your content does not fall under HKUSU or your academic studies, but is still related to the university, you may wish to seek the help of a student orientated university office, such as CEDARS, to upload under their account.
Can I submit content to U-Vision if I am not a member of HKU?
U-Vision only accepts submissions from HKU sectors. If you are not a member of HKU but have material that you would like to broadcast on U-Vision, please make sure it is relevant material that would be accepted by an HKU department / faculty / centre / organisation and acquire endorsement of your submission via that related HKU party. We only allow submission accounts to HKU parties, so you must let a relevant HKU party submit the material on your behalf.

I don't have video editing software, can you help?
You can use our Video Composer. It's a free, online video editing application that you can use to compose your slideshows and videos.

If your content has a ratio of 4:3, it will be displayed like this sample. Alternately, if you are absolutely sure that viewers will be able to grab all critical information from your content at a glance, your content may be displayed fullscreen, without the supporting side panel text, like this sample.

U-Vision & Campus TV Relationship
We would like to acknowledge the invaluable input of Campus TV in the creation of U-Vision. Their help made the transition from concept to reality possible. However, U-Vision and Campus TV will remain independent institutions as both parties wish to retain their full creative autonomy.
Sustainability is a major focus at HKU and is directly targeted by U-Vision. The use of digital communication is an effort to reduce the number of printed posters and banners used around campus. Along with paper waste reduction, U-Vision will also pursue energy-saving practices. At present, the TV monitors will only increase HKU's total electricity consumption by approximately 0.04% in reference to 2005 and 2006 figures. (Excluding the larger LED monitors), HKU's total electricity consumption will only be increased by approximately 0.01%.
