VIDEO ON DEMAND in SPORTS EVENTS

 

Receiving Video feedback that comes from selected taped attempts in individual as well as team sport performances has been a well-known approach for years, when (1997) Chang, Ch. W. and Lee Sh.Y., based their research on sports events for further analysis and tactics through a central Video database; at that time, the particular approach was rather inapplicable, while later on (2000) Lindner et al., suggested real time multimedia data transmission approaches. Last but not least, the original globally yielded results of a relative multimedia database survey developed by Tsibiris A., Tsamourtzis Ε., Sfingos N., Zaggelidis G, and Zaggelidis S, provided the motive for further approach development, which was actually applied by the Athens 2004 organisation within the Olympic Village .

 

In particular, a Video database was developed in favour of the participating athletes’ coaches, the athletes themselves and the journalists alike, according to which their wish to watch - upon individual demand - their own as well as their opponents’ performance was fulfilled (zipped MPEG I version).  Similar access to the available application over the Olympic Village intranet was also provided to the groups of journalists within the Village; however, the particular information was not accessible by the public outside the Village. The audiovisual material accessible to the athletes and their coaches, icluding journalists alike within the Village,  was of a total length of 3,360 hrs. (video time). The project was fully and successfully accomplished.     

The research conducted on the consequent use of the video taped material yielded positive reconstruction of the software operations, according to the successive findings of the experts (Aichele D.B., Caste K., 1994), (Tsamourtzis Ε., Siskos Α., 2001), (Sfingos Ν., Tzekaki Μ., Tsibiris Α., 2006): the development of a client/server network application (50 Mbps) using a central Data base of the potential for audiovisual information transmission over to interested third parties, such as Sports Associations or the Ministry of Culture, General Secretariat for Sports.

 

SOFTWARE & APPLICATION PLANNING & DEVELOPMENT

The previous application gave its place to a multimedia application using Borland C++ (Hollingwirth, 2004). An advanced TAMovie cohesion was used for the video feedback. The relational databases (Elmari R., NavatheS.B, 2001) used can support the whole of the database advantages. In particular, (RDBMS)  MySql has been applied. The application has been characterized by the four different tabs it holds, namely: a) entry-analysis, b) quest-feedback, c) video database management, d) recording-digital video development. The application is based on project development and phase entry according to criteria-keywords related to the video content (Körndle H., Marder U., Robbert G., 1998).

CONCLUSIONS

The Sports Video database application enhances the potential for effective combinations of recorded best practice events in sports training, analytically presented games as well as examples of contemporary trends in sports activities in general, so that all interested parties e.g. atletes and coaches alike could refer to it for gaining all related available multimedia information. In due course, the support of this version by internationally acceptable standards (mpg, avi κλπ.),  will transform the application into a kind of inheritance to future generations for further enhancement of all sports activities.
