1. A nitride-based light-emitting device comprising an active layer between an n-type clad layer and a p-type clad layer, wherein:
an ohmic contact layer made of a transparent conductive oxide is formed on the p-type clad layer,
the ohmic contact layer and the p-type clad layer are in direct contact, and
the transparent conductive oxide is one selected from the group consisting of a first transparent conductive oxide comprising gallium, indium, and oxygen as main components, a second transparent conductive oxide comprising gallium, indium, tin, and oxygen as main components, and a third transparent conductive oxide comprising zinc, indium, tin, and oxygen as main components.
2. The nitride-based light-emitting device of claim 1, wherein the ohmic contact layer comprises at least one metal as a dopant for the transparent conductive oxide to adjust electrical properties of the ohmic contact layer.
3. The nitride-based light-emitting device of claim 2, wherein the dopant is used in an amount of 0.001 to 20 wt %, based on the transparent conductive oxide.
4. The nitride-based light-emitting device of claim 1, further comprising a metal capping layer made of at least one selected from the group consisting of Ni, NixOy, Au, Pt, Pd, Mg, Cu, CuxOy, Zn, Ag, Sc, Co, CoxOy, Rh, Li, Be, Ca, Ru, Re, Ti, Ta, Na, and La on the ohmic contact layer.
5. The nitride-based light-emitting device of claim 4, further comprising a metal interlayer made of at least one selected from the group consisting of Ni, NixOy, Au, Pt, Pd, Mg, Cu, CuxOy, Zn, Ag, Sc, Co, CoxOy, Rh, Li, Be, Ca, Ru, Re, Ti, Ta, Na, and La, between the p-type clad layer and the ohmic contact layer.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for retrieval and playback of buffered content, comprising:
buffering a content stream to a buffer responsive to a request to pause play of said content stream;
retrieving said content from said buffer for playback of said buffered content stream responsive to a request to resume play of said content stream, thereby emptying said buffer, said retrieving step further including:
selecting for playback any frames of said content retrieved from said buffer in accordance with a selection frequency;
increasing said selection frequency from the time when said content is first retrieved from said buffer and until said buffer is completely empty;
dropping any frames of said content retrieved from said buffer in accordance with a dropping frequency; and
decreasing said dropping frequency from the time when said content is first retrieved from said buffer and until said buffer is completely empty,
wherein said buffer is emptied at a faster rate than the rate at which said content stream is buffered, and the rate at which said buffer is emptied varies, said buffer being emptied at a rate that decreases over time, and wherein the playback rate of content retrieved from said buffer decreases in accordance with a predefined function of a given time allotted for completely emptying said buffer and the playback rate decreases non-linearly;
playing said content stream prior to receiving said request to pause play of said content stream;
pausing pray of said content stream responsive to receiving said request to pause play of said content stream;
playing said content retrieved from said buffer from the point at which play of said content stream was paused; and
playing said content stream from the point past which said content stream ceased to be buffered.
