Restudying the Legal Status of Audio-visual Materials

There has always been dispute between two opinions of regarding audio-visual as an of evidence and as a of evidence.To solve this dispute,we must firstly have clear recognition of the scope of audio-visual materials.From the angles of semantic analysis and legislative study,audio-visual materials include sound-recording evidence,video and computer evidence.The dispute between independent category and non-independent category can be thought to be question of whether audio-visual materials can be classified into documentary evidence.It is to some extent reasonable to classify sound-recording evidence,video and computer into documentary evidence,but this is not practical in the context of our country.To clarify the legal status of audio-visual materials is helpful for the establishment of the evidentiary rules governing the use of audio-visual materials and the procedure and approaches of evidentiary investigation.
