Crosstalk

In electronics, crosstalk is any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit, part of a circuit, or channel, to another.

In cabling

In structured cabling, crosstalk can refer to electromagnetic interference from one unshielded twisted pair to another twisted pair, normally running in parallel.

Other examples

In telecommunication or telephony, crosstalk is often distinguishable as pieces of speech or signaling tones leaking from other people's connections. If the connection is analog, twisted pair cabling can often be used to reduce the effects of crosstalk. Alternatively, the signals can be converted to digital form, which is much less susceptible to crosstalk.

In wireless communication, crosstalk is often denoted co-channel interference, and is related to adjacent-channel interference.

Crosstalk (comedy)

Crosstalk, also known by its Chinese name xiangsheng (simplified Chinese: 相声; traditional Chinese: 相聲; pinyin: xiàngsheng; literally: "face and voice"), is a traditional Chinese comedic performance in the form of a dialogue between two performers, or, much less often, a solo monologue or, even less frequently, a multi-person dialogue. The language, rich in puns and allusions, is delivered in a rapid, bantering style. Crosstalk is one of China's foremost and most popular performing arts, and is typically performed in the Beijing dialect (or in Standard Chinese with a strong Northern Chinese accent). The acts would sometimes include singing and musical instruments.

Canadian crosstalk comedian Dashan (Mark Rowswell) says the closest equivalent in English would be Abbott and Costello's "Who's on First?" sketch.

Format

Modern crosstalk is made up of four skills—speaking (simplified Chinese: 说; traditional Chinese: 說; pinyin: shuō), imitating (simplified Chinese: 学; traditional Chinese: 學; pinyin: xué), teasing (Chinese: 逗; pinyin: dòu), and singing (Chinese: 唱; pinyin: chàng).

Cast

Production

In 1979 Keith Salvat, who had made the film Private Collection (1972), wrote a script inspired by Rear Window (1954) called High Rise, about a man trapped in a high rise building because of an injury. He received from development money from the New South Wales Film Corporation and wrote early drafts with the assistance of Byron Kennedy. Then Ross Matthews became involved as producer, and the NSWFC agreed to finance the entire movie themselves under the title Wall to Wall...

Just before filming commenced Ross Matthews got another film funded, Hoodwink (1981) and so brought in Errol Sullivan as co-producer. Filming began in 1981 and was marked by difficulties and tensions, particularly between Sullivan and Salvat. Salvat shot for 19 days, then on 31 May 1981 Sullivan and Matthews fired Salvat and replaced him with first assistant director Mark Egerton. Production was shut down for a week while Egerton and Denis Whitburn rewrote the script. Among the changes made were a new opening sequence and removing most of the exteriors so more scenes could be shot in the one set.
